Information Quickly Motocross

I know that's not for a ATV but I need the specs of engine compression on a Cr125 1998.Maybe all years can be the same but I need the PSI Range that the engine is supose to be good.

Thanks

I can't remember for sure. But since your asking for a quick answer I'll take an educated guess. CR125s have lower compression than most engines--your not going to see 200psi or anything....

150+ psi at sea level would be excellent
<120 psi at sea level would indicate time for a new top end
lower than 100 psi and the engine may not run at all
