I just did a tach plug delete on my 650 and have a spare drive sitting on my shelf. The 500, 550 and 650 tach drives are interchangeable. If you want it shoot me a PM.



 The 650 tach drive HOUSING should swap, but the gear drive inside is different. Just FYI.

Thanks for the clarification. Well, if her drive gear is still good then she can use my housing.

I'm UP I'm UP! Not gonna lie, all of the above is true. I like things with a bit of grease and patina, like my bikes and my face.

Hey Marissa, nice 500 and nice work space you have. I think it's best to pay extra for the bike you really want rather than settling, so nice score! Also CT isn't cheap. People are still selling rattle can basket cases for $1800. I had to go into NJ and NY for better deals. Regarding a bike with paperwork, in CT a bike doesn't have to be titled if it's 20 years old or older. None of my bikes ever had a title.

Where in CT are you? I'm in Monroe (fairfield county)

Your comment about bikes in CT couldn't be more true. For whatever reason, it's IMPOSSIBLE to find a solid bike for the money here. If I had a truck I would have easily gone to NY or Mass for a bike with a good price. I paid $1600 for mine, a little steep but worth the investment to me. I don't want to cut any corners with this project.

Also, located in Guilford (New Haven county). Do you know of any Honda bike clubs? Not that I'll be riding soon, but I would love to have some people to ride with when the time comes. It seems like that can be safer at times.

Marissa welcome, and beautiful bike!
This is my ladies cb500/550. She is 5'2 and while the bike is slightly big, she touches both balls of her feet to the ground.
I had an upholsterer thin the foam on the sides and top of the stock seat pan. Worked out very well.




Good work so far btw, and you came to the right place

A few years back a guy gave me his business card at a stop light and said he held vintage motorcycle meets certain weekdays in Bethel. I haven't actually gone to one and the coffee shop where he said they met got bought and turned into a book store (only in Bethel could there be demand for a mom and pop book store...it's across the street from the Bethel Democratic Party meeting house I sh*t you not, haha).

I don't know of any other clubs, let alone Honda clubs. I just ride with my buddies. There are a few other members in CT, though. Ericcb750 is around your area I think.

Thanks everyone for the warm welcome and advice! Here's my progress this week.

Taking a break from the carbs for now because I need to get a bunch of other components dialed in first. I know as soon as I get it running right I'll want to ride, so I'm addressing them now since I was able to bring the bike back to life.

I've addressed the rear shocks and went with Emgo progressive shocks. They're like a half inch higher than stock but seem like good quality for the money. I'm a little paranoid about the geometry of the suspension now but I haven't even addressed other factors yet. It is something I'm going to have to keep my eye out for in the future. (Note: is there any sort of algorithms or tests to see how much the geometry has been altered?)

Now although the shocks raised the height a hair, which seems completely opposite of what I was looking for, I went ahead and mocked up a seat pan and laid down some foam on it. It's already a lot better than factory and it's not even covered!I can't flat foot but I come fairly close and at this point I don't think it'll be an issue. I've already become used to walking the bike back and forth in my garage on my tippy toes, having to tilt the bike side to side, so I'm fairly confident with it.

A trick I used when making the pan was starting with cardboard, and make your template so the waves in the board are running along the side of the bike itself. Then, when you try to make a bend, instead of using your hands and crushing the cardboard, just lightly take a box cutter evenly through the board and you will have made your bend just by doing that. What that does is create a score line, letting the inner waved paper become a hinge and all you have to do is now flip over the template and that board will bend very well at that score line. I might have to take pictures of what I'm talking about for you guys to understand, so if anyone is interested, let me know!

I also saw a lot of videos where people just took a sheet of aluminum or steel and cut it with a plasma cutter or a grinder (lucky them!) and used that as their seat pan. Granted, I don't know what gauge metal they were using, so I can't say, but I noticed my pan felt incredibly flimsy with the traditional (is it 12??) gauge metal for autobody that I've used for my Z in the past. So, what I did to correct this was take my edges that were uneven (thanks to my fabulous dremel and super old sheet cutters) and shaped them using my hammer and dolly to sculpt them inward and thus add rigidity and improve the lines. Voila.

Now, I'm going to dial in the styling and modifications of the rear end to make sure it works with current suspension. I don't plan on going too extreme as you can see (No frame loops used here folks!) But it's definitely being changed. The rear fender and tail light hang way too far out for my liking. Not to mention, all my OEM parts are being stored away safe and sound in case the day comes where I want to restore it to factory specs :) I'm still drafting designs but you can kind of tell what I'm trying to do with it.

Don't get me wrong, I love the looks of brat seats on CB's, but after seeing the amount of modification that's needed to get that look and the fact that most relocate the tail light, I don't want to do that right now. I'm trying to keep the bike safe, remove weight, but also do little things to gradually take it to the look I want. But there's no way I'm moving the tail light, and if I leave the factory tail light on and try to make it work with a brat seat, it'll just look bad.

 Too many old people and folks on their phones for me to feel comfortable with my light down by the axle, at least with it closer to eye level that gives everyone a chance at a better reaction time. I think I want to go with LED as well for that same reason. We'll see what happens I guess!

My Biltwell helmet came in and I truly love it. The color is a little more saturated and red than my bike, but that's also partial to the sun fading on it. I think they still work together regardless. It's so 70's. The build quality is excellent too, especially for the money!

Next on my list is deciding what to do regarding my wheels and tires. I wanted to get them replaced at a shop but places want to charge $120 an hour and quote me 5 hours to do wheels and tires. I think I'm better off just buying a balancer and doing it myself, and investing in the stainless steel spokes as well. I've already been balancing wheels and tires for years on cars so I understand the concept. I'm more so just concerned with getting the spokes right and taking the wheels off the bike correctly. I was thinking about even buying a spare set of wheels so I don't have to disassemble mine until I get the set up right on the spares. Just curious if it's common for people on the forum to do this work themselves. Also, does anyone have tire recommendations? I'm looking for a set that perform very well for a new rider who isn't looking to go too fast, nor will ever ride in the rain or on the highway.  And preferably look a little old school just so it's more period correct :)

Wheels are pretty easy to lace. Take a pic first, then count the cross pattern, jot ot down, and whether the inners cross or all go the same way. You can true them on the bike if need bem spoke wrenches are cheap. Call here for help if you get stuck.

I had never done wheel lacing before and I did it successfully without a truing stand. It just takes time and patience. You'll get it.

 Why are you relacing them? Just clean the spokes with some 0000 steel wool and polish up the hoops.

12ga steel would be nearly an 1/8" thick. That's pretty thick and should feel plenty sturdy. 11ga aluminum is more than stiff enough, and you can jut aluminum with wood working tools. Use a bar of soap to wax the blade before you cut, and it will slice through like butter.

You can also have an upholsterer staple or glue onto the aluminum. I prefer it to steel due to no rust issues, easy workability, and weight savings.

There are online suspension calculators that you can use and plug your measurements into. I doubt very seriously that you have ill-effected the geometry to a noticeable degree by a small rear shock length change.

I think Bridgestone BT-45's get the common recommendation for period-esque decent tires.

YOU can easily lace your wheels. And true them. Then just have a decent shop mount the new tires and balance the wheels. Plenty of threads here on balancing and truing, or YouTube videos.

What's your goal with the wheels? Just to clean them up or do you want stainless spokes? I'm with Scott that you can just polish them up and maybe hit them with a semi gloss clear for some rust prevention. That being said, lacing and truing isn't that hard. I've seen a bunch of newbies here do it just fine the first time.

You dynamically balance car tires. 99% of motorcycle tires are statically balanced. It's super easy, watch a YouTube video about it. I made my own balance stand out of a rod and skateboard bearings.

Oh, and you say now that you'll never go on the highway. Once you're fairly comfortable on the bike you'll venture out. I had a CB125 which couldn't go on the highway and it was super annoying to me and other riders who had to plan out different routes. A 500 is more than capable of highway cruising.

Nice seat so far. Going to go with black vinyl? And don't focus on being able to flat foot both feet at the same time. I can't even do that with my bike. Many guys on the big BMW touring bikes can only tippy toe also.

Another suggestion to making the seat more sturdy is running a bead an inch or so in from the edge and maybe an inner bead line as well.

I agree with all of that. I'm 6' tall and on my wr250r I am tippy toed. It's just the way it is.

IMO the highway is the nicest of rides depending on the conditions. Just relax and cruise.

Hey!  Welcome to the best forum on the web Marissa! I have a similar build going, but with a 1972 CB750. I got mine because it was the year I was born. Very similar color, Brier Brown Metallic. I also lean toward the brat style seats and drag bars. My ex-wife was very short also, she rode a 1978 Twin Star Bobber....lol! Good luck on your build!

The Husky 701 Supermoto is pretty spectacular, but I think the Yamaha would be fun to learn supermoto riding skills.

And yes, sorry about the threadjack!

Marissa, welcome! These gentlemen are already steering you into the right direction with your build. Looks like a great starting platform.

Here is a picture of one of my CB's I had recently finished:



Keep up the good work. Also, those old Z's are loads of fun!

Drag bar is very comfortable, at least on a CB750. Really good bike control while riding. I used drag bar on long tours here in Europe, about 2500-3000km each way.
I use std cable lenghts for both throttle cables and clutch. Upper brake line need to be shorter though.

Really nice to meet you Marissa and glad the tach housing is getting you one step closer to riding. Here are a couple links for you.

Exploded views of all parts of your bike with part numbers. I copy and paste the part number in eBay and buy things that way normally.

If you find a Honda bike club let me know, haha

Hey guys,

Thank you for all the warm welcome and thanks to Dave for answering all my questions and for having that tach gear housing. It works great.

Sorry I haven't been posting progress more, I have been really busy with work and working on the CB as well. I generally get home at 6pm and work on the bike until midnight or so. Sometimes I even forget to have dinner haha.

So, I ended up doing what I told myself I would never do, and I went ahead and cut the rear frame to install a frame hoop. Blasphemy! Honestly, I was just scared to commit to modifying this bike in ways that are less forgiving than others, but I have strayed from that fear at this point. So, with frame slugs and all, this CB is hooped and looking so good. I'm happy I went ahead with it.

Went ahead and ground down some areas of excessive factory welds. Didn't even remove too much, mostly just sanding it to an even surface and feathering the area with some filler. Initially, I wanted to use some fiberglass filler, but it doesn't feather out as nicely, and I ran out. Regardless, it shouldn't be an issue as everything is gone through and cleaned with alcohol before getting primed and painted.

Did an oil change and found a nice surprise at the bottom of the filter housing. Slightly concerned, I purchased a magnetic oil drain plug (for what little it will do) as a way to see if there's excessive wear in the future, unfortunately I don't know how long this buildup was in there for.

I went ahead and converted the turn signals to minimal LEDs which are really impressive when on.

 More blasphemy, velocity stacks. I went up 3 sizes on the main jet and I just ordered slow jets which are 2 sizes larger, so when those get here hopefully the bike will be able to go around the block or so.

Took the bike outside today and up and down the driveway. It was nice seeing it outside of the garage for once.

I fixed a couple of issues I was having; I rebuilt the petcock long ago and recently its starting to give me issues. The CB500's have two brass nipples and for whatever reason, I can only get fuel to flow out of one at a time. I saw a post from someone having the same issue but it never states if it was corrected or not, so for now I blocked the back opening and just added a Y connector to the first one so it feeds both sets of carburetors. Not a permanent solution but it works. I also had problems with fuel flow because I had a fuel filter on... I totally didn't want to take it off because it let me see how the fuel was flowing, but sure enough after I removed it I saw an instant improvement.

I also previously bought stainless steel brake lines from 4into1 and they were truly awful, I'm lucky I found this out while the bike wasn't on the road, now the bike has a nice set of Goodridge lines.

If you look closely in the photos you can see a battery and wiring box mock up... Unsure it that will be the final form for them but that's current. I still need to button up the wiring in the rear, get tires, and inspect the rear wheel to see if I should keep it.. there are multiple spokes that are bent and I'm worried there's a flat spot. I also noticed today that my front tire is rotational and on backwards... Luckily it's dry rotted so it's not a big deal regardless, but who does that...

I custom fabricated my own side cover panels as well.

Not sure how much progress will be made in the near future, I will be going on vacation and then shortly after that, back to school. I'm hoping to get the wheels and tires sorted out next after the carbs are synched, then move to rebuilding the front forks, installing bronze swingarm bushings, etc. One thing is for sure, definitely want to get the engine and frame powder coated this winter.

Your carb jetting changes are going to be way off very likely. Simply upsizing jets due to velocity stacks is not all thats required, and I doubt very seriously whether 3 sizes up on the mains is fully required, and 2 up on the idles is probably very large too.

Did you buy true Keihin brand jets, or were they aftermarket? Are your carb needles in the stock clip, or did you move them to an enriched setting?

Oil filter housing - I can't tell from the picture what was in there? Did you install the magnetic plug in the filter housing or beneath in the oil pan? Or both?

Don't get too rambunctious on grinding down factory welds. The stock metal tubing and flanges are VERY thin. Removing weld material weakens things further. Go gently and use filler to "add" where you might want to "subtract" so you can blend it out.

Sounds like a quick project for you is a Truing stand and replacing your wheels with new spokes  ;) Given all you've accomplished, I see that as a very minor effort your skills/determination.  :)
