I'm back onto the nsr project, still trying to diagnose whats stopping this grouse bike from running clean on both cylinders. The top bang hole fires fine, but I can place my hand over the others exhaust while its running and it dont make a difference at all.
I bought a compression tester and both cylinders are reading about 85/ 90psi.. Is this ok? can someone let me know what is spec?
Yes it has new plugs....
