If we didn't have a new head gasket we baked an old one in the oven for a while. Also we could spray Al paint on the head gasket. I always hand lap my heads on glass with wet or dry. I oscillate the head back and forth in a quarter circle rotating the head now and then. I use an inch pound torque wr...

I feel it is easier to count ratchet notches than shift notches. The five speed has one ratchet notch that is also a shift notch . The four speed has three ratchet notches and four shift notches The five speed has four ratchet notches and five shift notches however the fifth gear notch is also a rat...

The foot change ratchet is different. the four speed has three ratchet notches and the five speed has four. As I remember the ace 100 ratchet cannot be installed in the ace 90 shift cover. Clarence

Terry the circlip holding on the sprocket worked well. As I recall there was a wide and close ration 5 speed for the ace 90. The 90 shift cover had special parts to function. You could put on a newer shift cover on but it would change the shift pattern. I am still riding mine . Clarence back from th...

Merry Christmas back to you Paul and also to everyone. Too cold here for snowballs. God family and friends and many friends ride hodaka. Clarence

I have heard of blenzall before but now what the heck is a gravely and does it fit the hodaka. Clarence

I have had engines that were overtightened and the engine did not turn over you, would be fine with a firm hand tighten. You need a little sideplay in your shafts. I always make sure I have everything freed up then I apply sealer ect. You can also check the crank or the shafts one at a time. Clarence

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
