I just had the top end rebuilt last June and have only made it to 3 races since. The airfilter was cleaned and had fresh motor oil before each race. The compression ratio is 14.75:1, I ran VP u4.4 race fuel. The rwhp was around 70 hp. Looking to get $4000 or will trade for a stock 04-05 motor plus $2500 or a trx250r saber or puma drag motor. If interested text or call 330-330-0333.
