had hyper 7 4 about a year now never raced it. when racing when do u get time 2 set it up. eg with mine i need 2 get it warm then bring it back + just give it a little tune.
cheers it keeps running but always has a bit of flat spot on bottom end when 1st hot sow i just give it a little tune + its sound. might b something wrong with it but dont now enough 2 say what.
Sounds a bit like my engine (which has since died) might be a little rich - if you come down there's usually a couple of chaps that can have a listen and give their advice....
