EvilBanshee Posted March 21, 2012 Report Share Posted March 21, 2012 If your floats are'nt adjusted propper, You will starv the bike for fuel. I have done that before... It sounds like thats what happening. Orrrr it could be Bad Plug Caps, another issue i had, Once from 8000+ rpm, i would drop a cyclinder because i had a bad spark plug cap. Once i put on 2 brand new caps. The bike never ran better!! Quote Link to comment Share on other sites More sharing options...

I heard some guys on here bashing them so I did a search and found that for some guys they had a problem running the bowls dry which sounds like you may be experiencing the same effect. Theres more than one thread on here about the OKO's but I could only find this one real quick. If you search you might find out better info and pm some of the guys that had the problem to find out how they solved it. Heres the link to the discussion I found. Good luck http://bansheehq.com/forums/index.php?showtopic=129402 Quote Link to comment Share on other sites More sharing options...
