1997 zrt 800

richnn · 10-19-2009, 09:02 AM

I just purchased a ZRT 800 triple and PTO side cyl is not firing, but does have a spark, raw gasoline is dripping out of the exhaust.
Compression is about 90 , is it possible to spark plug wires are reversed or do they all file at the same time (3 x per cycle). Any ideas on how to troubleshoot

Thanks

compression is deffinetly low. does that engine have individual heads,i think my old 600 did. check your piston for some major gouging or wear.

90 is too low but the sled should still run on two cylinders....jmho

PTO cyl is shot - get a new piston probably. Raw gas is dripping from exhaust because it is not firing and not burning the gas.

90 psi is too low for it too run.
