A good quality but Cheap (ebay) o-ring chain and sprocket kit. Regina chain, and JT cogs. For a GPX 600 (15 and 39 teeth) but fits perfectly. Have a JT 13 tooth on the front so overall ratio is down from 3.2:1 to 3:1.. should be close enough and will allow for lower revs at high speed.

Frame bolt heads and threads wire brushed
