oh my aint that purdy,rest of bike looks pretty nice also! im gonna say as far as your overheating issue id definately run an oil cooler .youve basically got a healthy dragbike motor that would be fine a 1/4 mile at a time with a cool down between passes ,but stop and go traffic with those cams and carbs is going to keep it loaded up causing your overheating issue.heres a pic of that tach u can get a matching speedo too
Still recovering,some days are better than others.

Adding fuel mixture, cools the motor temp. In my opinion, I would rather be spot on at a idle and a touch, rich wide open. It buys me a safety zone!
You may also try retarding the timing. If you fire the motor at a later time, the motor has a longer cooling peroid.
Gear ratio - Every motor! electric or gas, has a speed that it likes to operate at. At that one speed, everything just clicks, the flow, engine temp, timing, fuel mixture, etc.
The age old trick, is to find that spot?? Gear ratio and riding style, affect engine temp.
Then, if you adjust to the problem and reduce the heat, buy an oil cooler, they look cute.
PS- If you lean the mixture, temp goes up. If you advance the timing, temp goes up. Wrong gearing, temp goes up.
I guess all you can do, is reduce cylinder temp or reduce cylinder pressure.............Take it for what, it's worth!
