I am an addict. There, I said it. H2

I tried soda blasting, but not aggressive enough.

I threw in the towel, took it to a known commodity:

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

Horse manure.
Anyone who has ever RIDDEN a hot 2-stroke, rather than clucking old wives tales would know that.

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.

Tell more about re-shaping heads...

Why?

How?

What is the benefit?

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.

Easily made? You did them yourself?

How?

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 ago, an aeronautical engineer explained:

"there are no such things as overpowered aircraft, just underpowered pilots"

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.

Explain how EVERY motorcyclist is not "tire dependant"

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.

Murrsickles are dangerous.

Low talent riders are more so.

Being afraid ENSURES that you will crash.

When is the last time you rode an H2?

When is the last time you rode ANY BIKE?
