They work well when you use the front brake the bike rises up rather than lower they do handle a little strange some times. Clarence

I don't have the data but what CW pipe is more desirable the flame thrower or the stinger ?? And I am looking also for the response to your question. Clarence

how about the superrat bracket tapered. also new exhaust gasket and tighten. Clarence

kinda sorta. There are times when a hodaka can't be pulled backwards in neutral running or not running. The kick start is hanging up just enough so when you pull back on the bike it pushes the kick start kicker forward into the clutch cover. I have seen this several times. It has never seemed to aff...

just a kind and gentle touch. I think Clarence

Use no silicone, your piston looks new. usually when when a ring breaks and the engine eats it, the piston is really torn up. Make sure no metal pieces are in the lower end. I think new rings would be a go piston tight and all. Clarence

The five speed race gears for the ace 90 worked great just a little machining had to be done on one case. I am still riding mine. And I think I have the literature for installation. There was a close and wide ratio set and there was a c clip to hold on the sprocket not a nut. Clarence

The early super rat frames number would start with B37205 the early rat engine would begin with M1001. What part of the country are you in?? Clarence

Just being there was awesome!! when about one thousand bikes fire up and take off in a group over a quarter mile wide The ground just shook. And the here and there boy from the north were lost in the pits. The film brings back memory's Good film! Clarence

The coil and bracket was made for the ace 90 it was to replace the internal coil also considered a race item at the time it has a bolt on bracket. I just don't use either on a small engine. A shot of gas from a oil can or I will do or a half teaspoon of gas down the plug hole. For neutral I would re...

Oil or melted rubber? If oil lean out mixture and tighten clamp. Make sure exhaust nut is tight and sealed. A air leak can melt the rubber. In about 1969 my ace 90 connection rubber to the exhaust pipe melted dripping burning rubber==++== forest fire tanker planes and everything not good!. Clarence
