Well after reading a thread about rebuilding the carbs on these CB650. I thought I would go ahead and try and fix the T-Fitting between the carbs.
Some times it is just better to leave things alone. Well I fix the t-fitting issue by using a small piece of fuel line and drilling a small hole in it. Bought a vacuum adapter kit which had an assortment of fittings. Use a reduce fitting and put a small amount of black sealer around the fitting for good measure. So while I was there I notice in the thread I read I was missing a small o-ring for the accelerator pump bowl. Decided to install one since I still had the parts from the rebuilt kit. I went ahead and clean out all the float bowls. They had a lot of dirt probably from the new tank. Well it was late and went to bed. Next morning I decide to put the 120 original jets back in. When I took the float bowl covers off the floats where stuck all the way out....what the hackers happen. :(  Come to find out I didn't blow out the remain carb spray when I clean out the bowls. The rubber on the needles had swelled up and can't be used any more. :oops: $50 down the drain. Lucky I still keep the old needles. What do I have to loose. I also took this time to bench sync the carbs. This makes the third time I took these carbs off. This time putting them back on was a pain to get mounted back. Don't know why.
With everything back together it runs like a champ :D No more gas smell. Also fix the vacuum lines going to the air box. So everything is back the way its supposed to be. So far no issues with the old needles. Just makes me mad when I screw something up I am trying to fix. Check out the pictures.
Oh do you think my rear tire needs replace? I am riding around the neighborhood with it. Assisted suicide. But its so much fun to ride. 8)

Lot of people poo-poo Shinko tires but they work well enough for my 71 year old not agressive but moderately fast riding style.  I usually buy from Chapparal using eBay.  Stay safe....Larry

I cannot believe anyone would think that is a tire that should be ridden on, no matter what the speed.

So true. When I get the new tires might just try my hand at scorching some rubber off this crap tire. I think it will peel apart very fast. ;D

How can this project go so wrong so quick.
I order another petcock (makes number 3) because not 100percent sure the old one is shutting off all the way. And also order a new fuel filter. One that I can take apart and clean out if needed. Really nice. So the new petcock doesn't fit after measuring and reading the description it should have fit. Was way too small. I really not in the mood to buy a $65 original petcock. Surely there is an alternate solution to this madness. So I go and put the old one back on. Now it is leaking for sure. Had to remove the tank and drain the gas out of it. Now I am stuck... :o Maybe hose clamp a big hose on the tank nipple and use a spring clamp to pinch off the hose...lol Guess that's what I get for trying to improve something that was working.
Anybody know of a cheap solution to a petcock replacement?

Oh I did start it up. Just had to hear it run. Man it starts right up on the first crank. No delay. Best it has run in a long time. Progress I guess. ;D

Death Bike
« Reply #133 on: April 23, 2018, 06:32:41 PM »
I think I should charge the name of this bike from Spare Change to Assisted Suicide bike. :o
So I finally got my tires on order and should be here by the end of the week. Have a pair of Kenda K657. Good price and free shipping. I also order a new chain. Had a buddy that rides and after I told him the o-rings where coming off. He said don't even think about riding that thing. So new chain coming. That was a lot of science and measuring that went into that purchase. So I thought I would get ahead of the game and take the back wheel off. Would give me a chance to inspect the back brakes. I knew they squeak a little. But what I found I have never seen before. The pad came off the shoe! OMG just to think I was riding this thing. Talk about a death wish...lol
So new brakes on the way. Glad I did this now. So all the parts should be here at the same time. Going to try and mount the tire myself. Watch a lot of videos on how to do this. Looks straight forward. Oh found another wasp nest when I took the side cover off.
One concern I have is the axle bearing seal. Should I replace it while it's off? What is the best chain lube to use on a o-ring chain?

Brake lining that has come off the shoe is nothing new.  That is why it is essential to check the brakes on a vintage bike...

Tire change
« Reply #135 on: April 24, 2018, 07:29:03 PM »
So I went to the local dealership to find out how much they charge to mount and balance a tire. If you have your own tire its $35 per rim. Doesn't sound to bad. So being the cheap-o I am and keeping with the Spare Change idea, the no money rule Honey. :-* I watch a couple of video on how to change out the tire myself. Seems straight forward and shouldn't be that hard for this old shade tree mechanic. So tired the zip-tie method. Work up to a certain point. I believe my problem was the tire was too hard. Was not warmed up and soft like most on the video. So I did managed to get it off with a tire spade iron tool.  :P So I cleaned up the rim check the bearings and all seems ok except for one o-ring seal. It's on order and should get here with the tires. I hope. I haven't gotten to the front tire yet. Wanted to get the back all done first. The bike is setting on the center stand and didn't want to rock the boat to much. That's all I need for it to fall over from being over balance to one end.

New Tires
« Reply #136 on: April 27, 2018, 08:25:41 PM »
Managed to get both tires mounted. Was able to balance the front tire no problem. The back tire is giving me a fit trying to balance it. With no weights it doesn't sink/fall. no matter where you place it the tire doesn't move. What are the odds that this tire is balance with no weights.  Found a shop that will balance it for $10. Might be worth it for someone else to look at it. Now I have my speed-o-cable not working again. I just knew when I took the front wheel off this would happen. I know it works because before I took it off it work. Must be something with the cable. I am thinking the cable is not long enough. Maybe have the wrong one installed. It came with the bike. So getting so close to getting it on the road.

Hey dumb question: I got my registration for the bike today. Where do you guys put the registration and insurance card on the bike? Like it doesn't have a glove box like a car.  ;)

You most likely do not have the two tangs on the speedo drive gear located correctly on the wheel.  If it worked before, that is the culprit...Larry

Here at least a photocopy of the registration is legal, but the insurance card has to be original (I think). Original is kept in a safe place in the house or garage.
I put them in a ziplock freezer bag in the toolbox, or tape that under the seat if there is nowhere else.

So the problem with the speed-o continues. If you remove the cable from the wheel, the tab inside spins and moves like it should. Connect the cable and remove it from the gauge. Cable moves. Put the cable into the gauge and it doesn't move. If you remove the cable from the wheel and hand spin the wheel the gauge moves. Its like the cable isn't going up into the gauge far enough.

Think I'll have to get a handle bar bag. Then place the registration in a ziplock bag. Can't but it under the seat. The seat is bolted down to the frame and I couldn't get it off if I got stop.

Took the back wheel to the dealership. Service Manager hook me up to balance the wheel for $10. I think I have the front wheel balance pretty good. Now it's time to put it back together. Then we ride... 8)

NEW TIRES
« Reply #140 on: May 01, 2018, 05:29:24 PM »
Well I manage to get new tires on the bike. Great deal on a set of Kenda. I was impress with myself to getting the old ones off and the new ones mounted. I just used what I had here in the shop. I couldn't get the back tire balance right for some reason. But the local dealership hook me up and got it balance.
Also installed a new chain 530x104L was the right one. Ya me ;D Lube it up with new lube. I have to say that is one sticky stuff. Also install new back brakes. Bike looks good and runs great. Last on the list is a new seat cover. But ran out of Spare Change. So a towel will have to do until get the funds for this project.
Oh and finally got it registered with the DMV. So she has a new Tag! And to top it off, Insurance! Can't believe how cheep it was. Getting fresh gas for her tomorrow.
New helmet DOT/ECS approved will be deliver on Thursday. Just need a jacket and IAM A CRUISING 8) Oh can't believe I made it this far. I will hit the neighborhood a few times. Practice some skills and might even venture out on the open road. Can't wait. ;D

Hey now that's a good one.

I finally took it out for the first time on the real road. Wow that was scary and awesome at the same time. :o 8) ;D So many things to think about while driving. Major problem is the people in this town don't respect motorcycle at all. They will ride your butt know darn well you could stop quick and they can't. I've clock about 30 miles on the bike now since I rebuilt it.
I am still have a small issue can't quit figure it out. Under a load it wants to stumble and you have to down shift pretty far for it to get over the stumble. Does it when taking off in 1st and 2nd. I wonder if syncing the carbs would fix that problem.

But wow... that was fun.  ;D

 The synch is important but won't cure a stumble. you could try some fuel system cleaner like lucas or techron but if you haven't done it you'll end up cleaning the carbs sooner or later.

 Congrats on getting your bike going, ride safe and enjoy. I found a big empty parking lot to sharpen my skills when I started riding again.
   I built a street rod on lunch money once, I ate a lot of cold sandwiches. For years. I still don't want  ham and cheese 40 years later.  I have the car to this day though.

I've cleaned the carbs twice. Will try and add a gas additive, but I don't think that is going to help much.

Been driving around our neighborhood. Its a big neighborhood and has some curves and hills. But a parking lot would be good too. I need to make it to the DMV. They have a course lined on the parking lot. But they never sweep it and has a lot of lose gravel. You would think they would keep it clean off.

Well I found the source of my leak.
The Petcock had a crack around the neck. When I went to tight the nut it broke. :-[
So now in search of a new petcock that won't break the bank. Anyone know a cheap alternative to the factory Honda part. Man the original part is pricey.
Or how about anything from another model Honda that would work. Better yet how about engineering something from a hardware store.
Weather is right to ride and I am missing out. Need a quick fix to get me back on the road.  ;D

 Go by the DMV on the Sunday before your test and sweep it off.

  If it's the petcock with the riveted on faceplate the Goldwing guys drill the rivets and tap for screws. Then you can replace the 4 hole washer inside and it's rebuilt. Some of our parts vendors stock the 4 hole washer.

New petcock arrived today. And it fits!! Order the Honda OEM part to make sure it works and fits like it should. Cost almost what I paid for the bike.
Before all this mess the bike was running great. Now it stumbles on load and hard acceleration. I even removed the carbs again and cleaned them out. Don't know what else it could be. Low battery voltage? Could the idle mixture screws be turned in to far? They are set to 2 1/2 turns out. I am about to give up on this bike. :o
