itzra Posted February 24, 2010 Report Share Posted February 24, 2010 Hello guys,i need your advice, i am getting ready my banshee for this season, lubing everithing, changing trans oil and all that stuff, and my uncle recomend me to change the piston rings, eventough the engine still running good, last year i used the quad alot, about 4 times a week, around five hours on weekends. he doesnt have a shee, but he has a very good experience in two stroke motocross engines so what do you think, would this prevent repair the entire engine in the future?

Larry's Shee Posted February 24, 2010 Report Share Posted February 24, 2010 Do a compression test, that will tell you. Quote Link to comment Share on other sites More sharing options...

In short, do NOT put all your trust in a comp test. I have seen them literally ready to grenade, all while showing perfect compression. If you beat on it for a year, spend a few bucks on gaskets at the least and open it to see how it is wearing. If nothing else, it will give a gauge as to how long the motor will last. You really need to mic the cylinders and pistons as well as inspect the rings for proper wear. Piece of mind is a great thing!

Piece of mind is a great thing! I def agree with blowit on this one, low compression is a symptom of a problem, but there are plenty of other factors. if you put a decent amount of ride time on your bike, you should take it down in the off season and look it over. I did this the second i purchased my last banshee because i bought it when it was -30 deg out side and i sure as heck wasn't gonna ride it, i comp tested it it was a perfect 135 in each cylinder... i took off the top end and as soon as i had the right side off, i noticed the skirt of the piston was holding on by a thread, if i had ridden it like that it probably would have fallen into the crank causing a disaster. new piston kit cost $150 which wasn't bad compared to the cost of a new crank and all the other damage that might have occured.
