I bought a 1987 Honda trx 125, replaced the carb, cdi box, checked all wiring, rectifier is good, timing is good, plug is good, it will start (most of the time, seems flooded though) and run some times but bogs when rpms are up. (The atv was missing both handlebar break levers when I bought it) at this point if it's the valves (can't find the clearance for this model) or reverse limiter or something else entirely. I do need the valve clearances regardless but any/all help would be so appreciated. Also how do I adjust the fuel air ratio.

Air/fuel ratio should be able to be adjusted on the Carb. Should be a little screw for adjusting on there.

I don't know about valves.

Both clearances should be .003mm both intake and exhaust make sure to adjust at top dead center on compression stroke.

My apology that is .003in I'm reading it from a post someone copied from there service manual
