Looking to buy a sled, 2001 SXR 700 triple with 3600 miles. Asked the guy what the compression is at right now, and he said 90 all around. I dont know nothing about triples, thought 115 was the minimum. The sled being a triple, What should the compression be all around? 120?

Thanks guys

It won't run very well at 90 psi.Check with another comperssion tester.For all 3 to be the same there must be something wrong with his tester.It is unlikely that all 3 cylinders are no good.100psi is the minimium.
