    New connecting rod teaser....

    We would make it so all the GX200 Parts fitted straight in it. we would also do it as a 3" Bore, But have more material around the block for extra support. We would probably make the deck much taller, like a built in extension so it could take a huge crank. It would be about £1000.00 To...

    So apart from your conrod being slightly lighter than the others, what other advantages does yours have? I was talking with Jarrett and he said increased lubrication, which would be the main advantage. Thanks, Dan

    mikuni 26mm roundslide vs. mikuni 24mm flatslide???

    Take the flatslide any day over round slide. The flatside performs much better, very easy to tune in and once set-up right we have never even had to change the jetting. Roundslides are hopeless, endless hours of trying to tune them in. Even when they are set-up about right, the flatslide is...
