I remember reading that article. I also remember a mechanic who purchaed the kit after reading the article. I remember it was a lot of modification to the motor. I also remember rideing it once and being amazed at how much power and torque it had everywhere. It was also quite expensive. I also remember it would eat the Banshee when it first came out by a large margin. There was a reason it used a +6 swingarm. lol. Klemm Research did a lot of cool things back in the day. Does anyone remember the tri-z motor in the early quadracer chassis? a very near true bolt in. The Z motor made a lot more power and was much more reliable. The Suzuki was really fast with that set up.

Man thats awesome that you got to ride that bike!! (er...trike)

Harry Klemm is still around if anyone wants to go to the source...
He is not in the ATV industry anymore but still doing 2-strokes building PWC motors. He has a company called Group "K" in Arizona.

A cycle shop that bears his name is still around in Riverside California although without his influence. Klemm Cycle.

Harrys old company back in the day was Klemm Research.

Curtis.

Someone should call him.

Honestly, I need to look at the article, but I don't recall them stroking the motor. I think they just bored it out and then had a big piston.

You know if people really are interested a specialty company could make this for you.

How much of a bore job would be required to gain an additional 100cc

Can anyone do the math?

You would need to bore it from 68mm stock to 81mm bore

With the stock stroke it would require an 81mm piston to be 350.4cc's. I don't think thats do-able with the stock cylinder. You'd be into the water jacket and head studs. 76mm (308) would be really pushing it IMO from looking at my old big bore cylinder.

Alright well now I have to find that Article to see what they used!!

I am pretty sure I know where a 370 Z top end is sitting.

[Darius1502]

Where, where?

Is it a special cylinder?

I am still looking for the article but can't find it....Il'l stay on the case!
