I launch my stock motor'd bike at 11K and I get 1.5-ish 60s out of it with the stock clutch. Pulled it apart after 30 or so runs and everything was fine. It does need adjustment after it reallllyyyyy gets warm.
I have the Brock's clutch mod ready to go on for next season, along with a pipe and a bazzaz zfi with qs.
I scanned this thread and it looks like I'm the only stretched bike here so my launch numbers are way off what everyone else is using. I have it lowered front and rear with a strap kit installed.
Yes it still wheelies at 10 inches back. Yes I ride it out. Looks better that way
