Still not going to get 90 on a super 8 or 9 with out thousands in it. And thats not including all the stuff you blow up on the way to figuring out whats going to work. I hit 86 on my zx50 ac but I have all the best parts, recently i bought the Malossi 25mm carb, air filter, intake, reeds, and a few more exhausts. I know I can hit 90 but it wont be safe, at 86 I felt like I shouldnt be doing it. Also further more I run my engine on a severely lighter chassis than the zx or supers.
Definitely check out my build, I just posted a few new pics of new parts I got. I just spent another 1500 on dio parts.
