ah2009 Posted August 23, 2007 Report Posted August 23, 2007 Hey everybody! I got my first banshee this weekend and could use some help and info. It seems to run fine but has about 60 lbs of compression in each cylinder when i kick it over. I can kick it over with my hand. From what ive read, this should not run if it was that low. I havent been able to take it out and ride it yet because i had to order the front drive gear, so i dont really know what the power is like, but ill find out soon. Would it hurt anything to run it this way?? I was thinking maybe top end rebuild??? Thanks!! By the way this seems like a great site!! Quote
fastbanshee8 Posted August 23, 2007 Report Posted August 23, 2007 If your compression tester is known to be good, then 60 lbs. is very low. Personally, I wouldn't even start it, let alone ride it, until the top end was rebuilt. A top end rebuild is recommended at 100 lbs. or lower, and if you can turn the motor over with your hand that easy, then it's definately time to rebuild it. By running it, you could end up breaking a pison skirt, and cracking the cases, and/or destroying the crank, besides tearing up the cylinder walls, and breaking a rod. If you keep running it with that low of compression, then you will have a huge repair bill. Quote
J-Madd Posted August 23, 2007 Report Posted August 23, 2007 Are you holding the throttle open and kicking it until the gauge stops?? At 60 psi, it should run like crap. Quote
TJ10 Posted August 24, 2007 Report Posted August 24, 2007 Are you holding the throttle open and kicking it until the gauge stops?? At 60 psi, it should run like crap. If you can kick it over by hand, it doesn't matter if you don't hold the throttle open when you check it...you need a new top end. With that little compression, it would be like riding around with a golf cart motor. Quote
ClimbAnyHill Posted August 25, 2007 Report Posted August 25, 2007 I don't even think you can kick em' over under 100. Stock should be 130psi. Quote
ah2009 Posted August 26, 2007 Author Report Posted August 26, 2007 Thanks for the info! I think im gonna have to try the top end rebuild. Quote
KaosBanshee44 Posted August 26, 2007 Report Posted August 26, 2007 How many kicks does it take you to start your bike, good compression should start first kick sounds like you would have to kick it 15 times for it to start. Quote
black sunshine Posted August 26, 2007 Report Posted August 26, 2007 Verify that your tester is in good shape somehow. Quote
