Survey Viper Compression


Junior,your Probably A Better One To Explain This Then I.more Compression Doesn't Always Equal More Performance.as Long As There Close In Compression,don't Worry About It.unless Of Course The Compression Is Extremely Low. I Beleive My Viper Is Around 130,125,125 And It Runs Awesome!!!
 
Remember the viper has a lower compression ratio for the pto cylinder. I wonder if it could be the YPVS or maybe the rings that are bad?

I looked inside all the cylinders with a borascope and they looked great + heads were clean. I just wonder what will my compression be next year when the sled has double the mileage (currently 400miles) will it go below 100psi?

I didn't break the sled in, I bough it with 300 miles on the odometer.
 
if the cyls look good, rider. compression might come into line more with more seat time.
