Yanbansh04 Posted July 9, 2013 Report Share Posted July 9, 2013 Hi, i have a 7mm cub, I run trail and some street, and i think my timing is too high, i have +7, i want to know the bike will work better with +4 or +5 ? Because my bike don't run great at high rev or low rev depending how i jet ( pwk 33mm, 45pilot, 172main ) 160psi( the engine is new ), thank and sorry for the bad english Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted July 9, 2013 Report Share Posted July 9, 2013 try running it on +4......USUALLY the only people you see running that much timing are guys running them on alky. Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted July 10, 2013 Report Share Posted July 10, 2013 Well what is huge rest of the set up? There could be some other variables. A lot of gas cubs out there loving 7 degrees of timing. Quote Link to comment Share on other sites More sharing options...
Finch Posted July 10, 2013 Report Share Posted July 10, 2013 my gas 392 loved +8 Quote Link to comment Share on other sites More sharing options...
Zillaguy Posted July 10, 2013 Report Share Posted July 10, 2013 My pump gas, stock cyl. 4mil LOVES +7, it seems to rev out quicker @+7 than @ +4... I'm running my squish band clearance at .050" which keeps the compression in check so I can run pump gas and +7... Just be careful to listen for deto under a big load.. if no deto occurs you're good... Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted July 13, 2013 Report Share Posted July 13, 2013 Big difference in the way a cub responds to timing then a stock cylinder set up though. Quote Link to comment Share on other sites More sharing options...
