More wiring yay
Itís a time consuming process when you do it right. All joints will be soldered and sealed.

Tying to visualize a full leather two person seat with the back half ďcafeĒ hump styled instead of just flat.

Also considering making the rear fender into a hugger style. I think that would look killer.

Yup, digging both those styling cues.  The two-up seat looks great (and could work well with the lines of the rear subframe), and the hugger fender could definitely work too.  For some reason I think having the fender end directly below the end of the seat hoop accentuates the gap between the two - I'd love to see how it looks with the fender tucked away more just as a comparison.  Damn that fender's nice and shiny!

Jimbo, here are a few different amounts of tuck on the fender. Iím thinking tucking it in deep then making a small black or carbon fender about 3 to 4 inches attached under and sticking out from the rear hoop(see example). Iíd need that little fender on the hoop to keep from getting water up my back if I tuck the chrome hugger too deep.

Got my new valve clearance numbers after the rebuild and they are a little tight but still ok. I may ride this season and add it to the list for next winters work.

I also pulled the carbs back off because itís not running right between 1/4 to 3/4 throttle. Starts to burble and lose power. A few carb experts are telling me itís too rich so Iíve got a few genuine Keihin jets coming with a few sizes to do some testing. It has 68/102 now but when I do the idle drop procedure Iím ending up with pilot screws turned nearly 4 out and the plugs are sooty.

I also used this as an excuse to pull the started motor out and clean and re lube the shafts. There was a horrible noise coming from the started motor and now it purrs

I still and stumped on what to do about a seat and side covers. Those covers are hard to come by and everyone wants crazy $$$ for them if they arenít cracked.

.003 and .004 might cause you some dramas, better to be loose than tight. I bent an exhaust valve from not having enough clearance. But if itís already running maybe sheís all good.
Iím digging that rear fender looks mean.

first cafe build was an incomplete learning experience, more of a test run for the real thing FRANKENHONDA II

Iíve been so busy with work, this project has slowed more than I hoped. I got a few sizes of jets and Iíll start with the 98s to see if that helps the burble and sooty plugs.

Cracked side covers are easy fixed with ABS plumbing cement and a little fiberglass cloth on the inside if you think reinforcement is needed.

My covers are completely missing the tabs on the back that plug into the rubber grommets on the frame
