[img]i/expressions/face-icon-small-confused.gif[/img]I am buying a 2002 Yamaha Blaster,just for a Extra Ride,My question is,how much compression shoud the motor have with a 240 Over-bore done on it??? The guy that has it say,s he had it worked over and the builder told him to run race gas in it!!!!! If it,s not over 150PSI compression would that be nessary?????.i have a Banshee that is Built,I run 145PSI compression on it,and it run,s fine on pump gas. Thanks.

 

140-160 psi is stock compression. no need for race gas just may want to run a higher octane fuel like 92. not sure on the compression on a 240. sorry
