252wheelieking Posted December 5, 2010 Report Posted December 5, 2010 (edited) Hi BHQ members, Im in need of advice for a little but big problem to me. What could be my problem? Im concerned with my jetting here in NC at sea level with temp ranging from 25-45 degrees now.....I had 48 pilots, CEG needles-mid clip & 158 mains @ .5 turns out. It ran fine when the temp was from 40-70 degrees. I didn't notice the difference in power until after I burned my clutches completely out, then it overheated & blew the head gasket on the left cylinder. I figured it had a blow head gasket because the left cylinder kept dying after it got warm up. It will run fine until it got warm & I could smell the coolant. So I installed new clutch kit, new head gasket, 52 pilots,CEG needles mid clip & 170 mains @ .5 turns out.Symtoms are now the left cylinder doesn't die but it backfires or spit back, it starts right up & if you give it throttle it stall like it wants to cut off. You have to pat the throttle lightly to get the RPM's up. When the RPM's rise they hang at more than idling RPM level & will not return to idle. I'm lost....Thinking about just rebuilding the whole topend over with new gaskets. But thought I'll check with you ladys & gentlemen first. All help & advice is appreciated.
