Awesome! thanks for taking the time to post all of your efforts up here. great thread. P.S. where does that Stoneface beer come from?? p.s. p.s. did you put a bushing in the mounting hole near the crack, it looks to be worn oval.

Newington (Portsmouth), New Hampshire.
Look closely, the hop bud is stylized to tribute "The Old Man of the Mountain"





All the mounting holes have some ovality. I am machining the cases to accept GT750 rubber mounts.
Then I'll make spacers to suit. The ovality won't much matter, the clamping force will be able to do it's proper job then.

I seem to remember my mates one ripping second gear apart ?
But he was drag racing it in a street class , it was denco tuned
Yup. The transmission (aside from a couple teeth on the gears) was sinply the H1 500 trans. re-purposed in the H2 750.

50% more engine capacity heaped on.... what could go wrong?!?!🤣🧨

Well, about everything. I'm $2K into the transmission alone.

Here is proof.
Why we call it inspection.
That things are always SUSPECT.

The undercut transmission is back from R & D motorsports.

R & L Engines phoned to say the cylinders are complete, fitted to the new cast pistons.

Time.... always in short supply.

If that paint stripper is working slow, I wrap the tank in food plastic wrap. It holds the fumes on the paint. Just my two cents!
Yes, bagging it, and then keeping it warmer. And thank you, for your help. 🍻

But, still, todays strippers aren't what we fondly remember. 🥳


This stuff is useless:

I watched one of my mates get on the gas too quick coming out of a corner on a race track a H2 - it stepped out and then shot him up the road. They always were good fun. The H2R was dangerous. They could step out two thirds of the way up a straight.
 
Looks like a good buy! If you remember these bikes made more power then the tire industry was ready for! I'd think modern rubber will make a great difference
Many people take life too seriously - just never stick your neck out anywhere you might be killed. Good tyres help you to become tyre dependent - then as soon as it rains, you are stuffed.
 
My brother uses H1 and H2 motors in speedway sidecars, and they are on methanol. The H1 is enough to win any sidecar race - the H2 is a waste of space. He looped the H2 when it came on song and jumped 3 metres into the back of another bike. It is simply too much, under those conditions.
 
Years and years and years ago I bought an S3 Kawasaki 400. It was locked up but after some WD40 down the cylinders and some rocking back and forth it freed up. I got it running and rode the snot out of it.

I find it's power completely controllable.
 
Like many things and/or endeavors there are people involved with differing abilities. There are some with the talent to exploit the qualities available and some that cannot. I am firmly in the latter category. As a young man playing with dirt bikes there were two members of our crowd that could thrash most of us with peaky small displacement two strokes with narrow explosive power bands . One of these guys was much younger than I , the other much older .
