Marty acetone seems to do nothing with gummy sludge and dried gas oil residue. My best results are with a few cups of lacquer thinner and some clean gravel or nuts ect. I pour this out and filter it and repeat until no more guck comes out. The threads on the petcocks are english not metric if you wa...

I have a F hodaka engine what was it out of?? And also a 100cc aluminum cylinder with steel sleeve, it is stamped W I it has the four bolt intake like a super rat, and a very large exhaust port, the cylinder is about 2 inches longer?? Clarence

Well I think you have a wombat head, unless I have my thoughts are in reverse. I think the CW head is 9 space 2501, wombat 952501?? Clarence

I sure agree with Ed here on the chain guard I have seen engines ruined by chains coming off and I think any chain guard is better than none . Clarence

I will check tomorrow I need 50cc parts for my autopet also. I also have a couple of the bigger yamaguchi engines that will fit in a hodaka. Clarence

Not good information, but I remember an old bell helmet ad that said if you have a ten dollar head buy a ten dollar helmet. Safety is very important. Sure is neat seeing comments, ideas and suggestions. Clarence

MTRob if you have any trouble with it call me if you wish. Clarence

It will fit Any ace 100 or ace 90. Clarence

There were leading link front forks made for hodaka in the 60's and 70's I have three./ One set is on my old ace 90 that I used for cross country and motocross up until 1973?? They handle a bump really well and if you use the front brake the bike raises up. On mine you needed good shocks also. My 90...

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
