Body work looks great with all the decals and emblems in place.

I thought the wheel truing spec was within .008" axially and radially? .0009" is lathe straight. lol

I misspoke. It's .009" .22mm. My mistake. I'm not sure my eyes could see .0009"!!

No you couldn't see if with anything other than a dial indicator or some such. I believe a human hair is right around .003".

I haven't actually found a Honda spec for trying but I've read within 1mm. That's too big of a gap for me. The front is .25mm and the rear right now is .5mm. It isn't getting difficult to get any closer but I will keep trying for another few hours

alright, I got the rear down to .42mm. that is good enough for me, its well under 1mm, I am happy. now I just put my new rubber dampers in the rear wheel (because I sheared off the tips of the old ones not realizing how expensive they were..) and now I am finding it near impossible to put the sprocket hub back in. the rubber dampers are so fresh and barely budge. I don't really know how to approach this, those are big chunks of rubber. I am afraid to beat on it with a rubber mallet because if I set the floating bolts  down in and hit the hub, they may fall over and I will be doomed to repeat the process of applying downward force while trying to keep the bolts upright....I searched for a similar problem to no avail, so if anyone has advice, please share. I may post the question in the sohc4 section.

Chef, Here’s the way I do it ...

Assemble the sprocket hub/carrier with the bolts, sprocket, sprocket shield, lock tabs and nuts. Snug up the nuts.

Apply a small amount of rubber friendly Dielectric grease to both sides the sprocket hub (red dots) and the rubber dampeners. All the contact surfaces should be lubed up with a light coating.

With the wheel laying flat, grasp the pre-assembled sprocket hub assembly with both hands and “walk” it in while pushing down until it fully engages into the wheel hub.

Apply the final torque to the sprocket nuts and bend up the locking tabs. Future disassembly will be easier too.

I sure like those left and right controls from Yamiya.  I'm going go have to try to make do with what I have just because I am already going to go way over my budget :-(  good job on the wheel trueing......I really think you would be hard pressed to find a tire that is that close to being true anyway.

Oh I know Gary. Thanks Ed, I like them too!

So I tried to mount my front tire. Watched lots of videos and got myself pumped up. Finally went for a go with the front tire and what a pain! I apparently got one bead seated easily. So easily that finally after an hour of grunting cursing and struggling seated the second bead....and then I realized I sealed up both beads without putting the tube it. Oh lord. So I unseated one bead and tried to get the tube in. I have never changed a bike tire, let alone a moto tire. I suck at it. I eventually coaxed the stem through the hole (rim strip kept moving on me making it very difficult) and then quickly realized I had pinched the rim and make two small holes. GAH! I did all the recommended tricks with winded and partial inflation and baby powder on the tube. I just don't know what I am doing. So I got 2 new front tubes and an extra rear tube from my local (hour round trip grrrrr) Honda shop and am about to try again. Wish me luck. Then I need to get ahold of some crimp on spoke weights and balance it. I do not want the stick on weights, not visually appealing to me at all.

Did you manage to get them on without marking up the chrome?

I think I'm going to have a shop mount my wheels. It took my cousin and myself some serious effort to get them off of the rims and I just can't see being able to put them on without marking something up. There is probably a lot of tricks I'm not aware of I guess.

Sucks about forgetting the tube and then pinching it off.... but these things happen sometimes in the heat of the moment.

I actually didn't mark it up. Took a gallon jug of Arizona green tea and cut out 3 oval pieces to use as guards. I wanted a shop to do them but I want to learn. Thesis of this whole project

Yep, tubed tires suck. I had to do the rear on my 550 4 times and ruined 2 tubes before it finally took.

My Goldwing front was both easier and harder. I got the tire mounted without damagine the tube, but the aluminum rims took a bit of a beating. I have plastic rim protectors, but couldn't find them. I will be repacing the back the Spring and I'm not looking forward to it, but I just can't make myself spend $40 to get it changed by a shop.

My tubless, cast alloy wheel FJ1200 was a snap. Did the front and rear, including takeing the wheels on and off in a couple hours.

roach, I've got 3 tire irons, I've read way too much about screwdrivers, I do not like shadetree mechanic thinking. do it right or don't bother.

update: I now have both tires mounted and no leaks! I have to buy some crimp on weights now and balance the tires when they come in. almost a rolling frame!

also received my rectifier and regulator from oregonmotorcycleparts, and tonight I am receiving some stuff from south sound honda, almost the last big order not counting the seat, wiring harness, and electronic ignition. slowly and surely...

Congrats. Tire mounting is one of those things that it helps to have someone with you to show you once. I would check those for slow leaks for the next few days. A front tire flat will likely be catastrophic.

Mounting tires is one thing I have no problem paying someone to do.
Not worth the time and aggravation to me.
I know a guy that runs a small bike/lawnmower shop, he changes them for me for a reasonable price (I provide tires/tubes/strips).

alright, update time!

I'll start with the wheels. I watched a lot of youtube videos to get pumped up. I didn't want to buy rim guards, so I bought a jug of tea with thick plastic and cut it up









next was to heat the tire up a little as its was chilly in the garage.



its really hard to take pictures while you are fighting a tire for the first time, so I didn't take any. I used tire irons, windex, and baby powder on the tube. during the front wheel I ended up seating both beads before I even put the tube in.....of course I would do that. then when I DID get the tube it, I pinched it and put two holes in it. gah. drove up to my honda dealership and got more tubes. got them on the right way, no leaks, but I'll be checking in a few days for any leakage. I am ordering some spoke weights so I can balance the wheels and get them on the frame finally. I love the way these look. so oldschool, so new.



my bubble shield came in the mail. love the color scheme.



rectifier and regulator from oregonmotorcycleparts arrived, so I put them on the bracket with the new solenoid too.





decided to clearcoat all my black parts with the 2k glamour clear. just wasn't feeling the matte look, and the 2k clear is more durable than the frame paint I used. I like the look of the clearcoat, so I am glad I went with it.





decided to clear the frame too, but I really wasn't going to take it all back apart again. so I taped off all the holes/threads/nuts and shocks. I managed to get all of it except the bottom of the tubes on the ground and the front of the frame by the headers. I will finish that up in a few days







also I clearcoated the tank with the vinyl stripes. turned out pretty good. I want to do 2 more coats though so when I get more 2k clear I'll do that last 2 coats along with the frame





painted the rotor and cleared it as well. love the look





got a bunch of parts delivered from south sound honda. new honda brake pads. here's to no squeaking!



new caliper adjuster bolt



new handlebar bolts. shiny



bunch o parts



I need a better system....I forgot what I ordered and armed with only the part numbers and a fading memory of whats left on the bike I had fun looking up part numbers and fiches to find it all out. then I wrote on the bags where the parts go. I got stuff to finish putting the heat shields on, and the entire passenger peg setup. I had none of it, I also got new rider pegs too.



forgot I did the caliper too.....that reminds me I have to clear the smaller half when the clear comes in



love the gauges, they look so new



heat shields are done, and two small (2mm x 4mm) holes in the mufflers were patched up with jb weld. the headers are still hole free and still rusty



thanks for reading :D

haha, if you have guns, use them! although for small projects like this it's hard to beat the price, quality, and cleanup convenience of the spraymax. proper prep, patience, and going slow allows a great result with almost any paint. this 2k isn't as forgiving as nitrocellulose, but it does burn in a little with itself making it easy to get a good wet coat.

I have my engine covers taped off and should be doing some more degreasing and painting today. I will be taking my carbs apart again to replace the main jets to 110 (341 pipes instead of 300) also putting in new brass floats (mine dont leak but I like peace of mind), and new float seats and float needles. I am also going to be painting the carb bodies to match the engine, as I can't entertain the thought of having them mismatch and look old when everything else will look new.
