Old pic Gene - it doesn’t look like that anymore…Rick your work area is waaaaay to clean and organized!
Horse manure.I was still racing my Triton 500, when H2 Kawasakis arrived. Ken Colvin had one. He rode around turn two on Winton Raceway and gassed it hard. The back of the bike came out, and the bike shot him up the road. It was very spectacular. I also saw one guy on an H2R replica get chucked up the road as he crossed the start-finish line, halfway up the main straight on Calder Raceway. He was really flying. Those crashes were usually pretty harmless. You would never gas an H2 unless the road was clear in front of you
Tell more about re-shaping heads...I never get into pulling two-stroke cranks apart. Learning how to build something which can become very expensive on your own bike can be false economy. Everything in a two-stroke motor is usually much closer to the limit. When H2R Kawasakis were raced in Australia Ron Toombs used to race them. He used to come from New South Wales to Phillip Island via Sale in Eastern Victoria. Kevin Doyle lives there - he reshapes cylinder heads to factory race spec. and rebuilds cranks, and he is still there. He also knows the port timings and chamber specs.
Easily made? You did them yourself?When the crank is rebuilt, the inner seals can be replaced with labyrinth seals - as in a TZ Yamaha. They can easily be made. I have them in my H1 motor. It also has Yamaha connecting rods.
Years ago, an aeronautical engineer explained: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.
Explain how EVERY motorcyclist is not "tire dependant"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.
Murrsickles are dangerous.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.
The Alrocle has spoken!!!Explain how EVERY motorcyclist is not "tire dependant"
Thank you.I have a set of crankcases available. ( UK)
Yam fj1200 uses a pair of small buffersThank you.
I spent considerable time modifying these.
I may need to add a stopper, for limitation of movement under full torque.View attachment 113211
The RZ has them on left front and right rear. So when pulling against the load, the torque has stoppers.Yam fj1200 uses a pair of small buffers
