So i was just wondering whats the best compression to run on a 240?Pro,s and con,s on how much is too much. ,140,150,160,180 or whats the best running and most reliable.Also if i have had the head milled already what do i tell the builder to get the correct setting for the head.ThanksI:I
 
Well i set it up for pump but im willing next year to run half and half.Just wondering whats the best comp. to run it a blaster like this for trail ridding.Never really have read whats the best recommended high com.Just would like to know.Thanks
 
they seem to really run best at 175- 180 pounds in my opinion ,of coarse youl l want straight race gas though ...a stock head can only be machined safely by so much for pump gas applications or your engine could detonate
