g-force Posted March 14, 2004 Report Share Posted March 14, 2004 i have a 1999 banshee that i bought used 3yrs ago. it still runs great, but may have lost a little power over the years. im not sure what all mods have been done to it. it has t5 toomeys,k&n with lid removed,and port work. i checked the compression and have 140lbs. on both sides. i know thats pretty good but i dont know what i had to begin with,it has the stock head ,milled im assuming. im wondering if a new top end is in order? by the way my elevation is about 1500ft.

MotulMonsta Posted March 15, 2004 Report Share Posted March 15, 2004 Three years without a rebuild? That's a long time. Your motor's just tired. I think it's time for a rebuild. The cylinders get glazed and worn, the piston gets fatigued and is more prone to break..the bearings get worn...ect. Three years is a damn good time span for a two stroke motor.

ranshee Posted March 15, 2004 Report Share Posted March 15, 2004 140 lbs. sounds good to me, but hell its always better too rebuild befor it blows up. I would rebuild befor it blows, should save you some $. Quote Link to comment Share on other sites More sharing options...
banshee tuner Posted March 15, 2004 Report Share Posted March 15, 2004 I'm not saying anyone is wrong but 140 is darn good compression and I would pull the side cover and inspect your clutch plates first. Or you can drain the tranny oil and inspect for clutch fibers, and since you have the oil out try some new 10-30 oil cause if you have synthetic that could make the clutch slip. And the most overlooked problem is clutch freeplay so check the adjustment at the lever. I just would hate to rebuild the topend when it's probably clutch related.
