tdod101 Posted September 14, 2014 Report Share Posted September 14, 2014 104 octane seems a little high no ? Probably just run 91 or 93 Quote Link to comment Share on other sites More sharing options...
91coupemike Posted September 14, 2014 Author Report Share Posted September 14, 2014 I was told with the 19cc domes I may need race fuel, once the hone gets in I'll have the top end together for a compression check Quote Link to comment Share on other sites More sharing options...
RadarRacing Posted September 14, 2014 Report Share Posted September 14, 2014 28s I have tuned on were in the 155 to 160 mainjet size but I would start bigger, maybe 162 or so they also sometimes need a needle change if they are rich off the bottom.

91coupemike Posted September 14, 2014 Author Report Share Posted September 14, 2014 Damn are the eBay Taiwan jets worth a damn? Gut tells me no, pocket tells me yes! The oem clones from jetsrus?

trickedcarbine Posted September 14, 2014 Report Share Posted September 14, 2014 No on the knock offs. You could contact whitbread about fuel injection if that's what you know and seriously would like to continue with Quote Link to comment Share on other sites More sharing options...
91coupemike Posted September 15, 2014 Author Report Share Posted September 15, 2014 Fuel injection on cars, lol I'll stick with carbs on the quad, seems way easier. Quote Link to comment Share on other sites More sharing options...
Brian Mcgowan Posted September 18, 2014 Report Share Posted September 18, 2014 good rule of thumb I use is plug checks. to black to rich. to white to lean. peanut butter is good. Quote Link to comment Share on other sites More sharing options...
