hi guys
well i bought this srx 2 years ago checked the compression and it only had 100psi(checked with 3 different comp. tester) i took the motor apart and found out there was spx or spi pistons in it.
So i put in brand new yamaha pistons and rings in there and tested the compresion again and same thing i still have 99 to 101 compresion
Now ive been running like this for 2 years never had a problem (knock on wood)
and i raced 3 different srx around town and i take them all bout 4 sled lenghts
i only have a hauck growler in there stock clutching
would some porting be the cause of low compression
p.s i tryed 5 compresion tester all together same reading
