Hey everyone I am currently doing some changes to the ttr125 I have. Heavy shock and fork springs as long with 20u weight fork oil. I figured I might as well do a valve adj while I'm doing stuff but I don't remember the specs (manual got destroyed by mice last winter). Does anyone on here have the intake and exhaust specs? Also the compression test spec if you could
thanks alot guys

Its .0031 to .0047, or 3-5 thousands intake, and 4-6 exhaust, checked cold. Compression, as a guess in a 10-1 compression engine, should be 110 psi or more.
There should be a decal under your seat with the valve specs on it. This bike is super quick and easy to set the valve clearances on.
