1 vs. 2 cylinder....
Mike,
After reading your post I just briefly searched the net for some info. I see that Rossi builds both single & 2 cylinder engine. I found no info on the VRP anywhere. I was told by a reliable source that they do make a 2 cyl also.
I too was told that Aarens(sp) isn't even in the hunt.
You got methanol on the brain?

Interesting that you ask this Question---Pro would allow any motor in these classes If you ask the people that MFG them for sale they will say theres.Originally posted by pav225 View Post
Rossi,VRP Aherns, make most of them. There are a few around made from
Motor cycle engines and for years Steve Litzell made one that was unbeatable.
So ya can buy the one that won the most last year or might hold any records.
But unlike stock or mod keying in on a MFG and thinking the one you buy
will not be obsolete in a few years or even one years is wrong.
There are a few guys that are very good engine tuners trying to make there own 125,175 right now and they will be allowed to run them.

175ccH Motors
Kind of curious....
Anyone know who makes the best 125 and 175 motors?...By "best" I mean the fastest.
How big of a class is 175 in the US? World?
