silverzl600

Also it was just rebuilt, and at the time of the rebuild i put a +4timing key in it and some new reeds. Ever since, it has run fine until its under a load, then it starts to break up on top end. Any ideas? Thanks for the help

I have an 89 banshee bored 40 over with some clamp on uni foam filters, and i just picked up a dyno port two into one pipe. I was wondering what it should be jetted to, right now it has 220's in it and im at roughly 1000' elevation. Any help would be greatly appreciated.
