A question I have been asked several times over the years. Short rods also.
I had kids asking me if I could add a "powerband" to it (the bike).

I used to send them down to the machine shop and ask for a long weight.

Was that a long weight or a long wait?

If I liked the kid I would send him for a short weight.

My mates in the machine shop didn't mind and it helped the kids with their critical thinking skills.

I talked with that customer today.

He uses longer rods and pistons with the wrist pin hole moved. I'm sure he buys them from JE and we trim the skirts for him.

It's an inline four cylinder jetski motor

This cat also has showroom mint Kawi triples, a 500 and a 750 in his airplane hangar.

Where he lives every property has access to a grass runway "Aeroclub" in Wellington.

I go to the dog park there, all I can afford
