i think my son and i have decided to keep it were going to tear it down and hopefully be able to get by with just replacing gaskets and a fresh topend and reeds. i will make sure to replace the thrust washers that were mentined above. other than that only thing else we will do is replace the suspension, wheel and axle bearings. may rebuild the rear shock and maybe a set of yfz450 front shocks. then ride it. we wil save our money for the next trx build we have been staring at in the garage for over a year. i may pm jerry hall if i run into anything strange in the engine. thanks guys
