I have a 96 sporstman with roughly 4000 miles on it and lets just say these 4000 are not "highway miles" I used to be able to keep up with the new 500's but ive noticed a decrease in power and performance. Anyone know of any good clutch kits that would bring this machine back to life? Or any other ideas for that matter....thanks

 

check the compression if its really low u wil need a rebuild

 

the machine still has decent compression, It was real bad so I tore apart the carb and found a sliver of metal in the main jet. That helped a lot. But still not where is was before....

 

Just jack up the plastic and park a Yamaha under it.............[img]i/expressions/face-icon-small-wink.gif[/img]

 

ill park a yaHaHa under it when I run it over [img]i/expressions/face-icon-small-wink.gif[/img]

 

time maybe for a new piston,rings, or reeds,that will ensure a consistant power running,whenever it is stock or modded.

 

anyone know what the compression should be? What would be considered too low?

 

As said befor with that many miles on it.Bore it new wisco piston and rings.The 96's are 2 stroks right.If so theres alot you can do to that motor.

 

nah, its a 4 stroke, not a 2 stroke.

the compression should be 120-140 psi
