Pretty fast quad, motorwork, clutchwork, etc., but still stock appearing. 50% turbo blue, 50% 93octane, 6.5 ounces of Castor 927. Very inconsistent take offs. Sometimes it screams, then it blows smoke and loads up for the first 50 feet next run. Any suggestions? If I change oils, but not amounts, how much will it change the jetting, if any? Comment?

 

PM lt80 he will probably know your prob.

 

Are we talking 6.5 ounces to one gallon? 6.5 to 2 gallons would put you right at 40:1 and that would be fine. When drag racing we lift the back wheels and gas the bike a couple of times to clean the motor out. The kids like to keep them idling and they will load up like that.
