ive got an 86trx and it seems low on power, the problem seems to get worse as the engine warms up. problem is most noticeable on the bottom. the engine is basicly stock, fmf fatty pipe and silencer, fmf ram valve are the mods. pilot jet jet is a 42, and the main is 155, they are set correctly by checking the plug and air screw, and the needle is in #3. compression is fine, tested that, and changed the stator. i am comparing this to an 86atc that i have had for 13 years with basicly the same mods, and it just doesnt have the same low and midrange that it has. comparison wise it runs almost identical to a z400 in a straight race, which is a little sluggish IMO. just looking for some opinions or some help thanks.
