qboronyrican Posted February 24, 2008 Report Posted February 24, 2008 i know this is a banshee forum but i thought maybe you fellow 2 strokers could help my friend out with his lt 250r quadracer.....im not sure where to look.......for banshee's i know but for him and his im not sure.....he would like to know 1. what should his stock compression be at sea level? (or where to find it he doesn't have a computer so i got stuck doing all the research) 2.how can you idenify what year a engine is from the engine #? 3.suggestions on the following problem....he had a problem where he thought the clutch went so i took it apart for him and found that the basket fingers broke (about 6 of them)along with about 60% of one of the clutch plates(in tiny pieces)....now im thinking that most of the pieces of basket and clutch plate are in the trans since not that much came out when i took the cover off.....what should he do cause im sure that will ruin the trans gears right?

Screaming Yellow Zonker Posted February 24, 2008 Report Posted February 24, 2008 Stock compression should be around 120 If the engine has the vin stamped on it you can go off the 8th digit. As far as the clutch goes it is best to split the case and clean everything or another failure will occur. Quote
qboronyrican Posted February 24, 2008 Author Report Posted February 24, 2008 (edited) 120?? are you guessing on that or do you know that cause others have said 150-160 in that range of answers i got but they were not positive.......as for splitting the case and cleaning it out, shouldn't he then replace all the seals and bearings at that point.....seems like it might get a little costly huh???

trapp350 Posted February 24, 2008 Report Posted February 24, 2008 I would research over at everything 2 stroke forum they have quite a bit of suzuki info. http://www.everything2stroke.com/ Quote
sled Posted February 24, 2008 Report Posted February 24, 2008 the 85-86 bikes dont have power valves, the 87s have a 5 bolt intake manifold. the 88 to 92s have a 6 bolt intake manifold. that should help a little with the year. those bikes also had a problem with crank seals blowing out. so you may wanna split the cases. i had an 87 that was ported, piped, and all that great stuff. it was pretty dam fast, but it kinda broke a lot. it always had some kinda of weird problem. mine had 150psi with a shaved head so 120 sounds right. hope this helps.
