motor was built by the owner of white knuckle to run at dome valley last year. it ran 1st in its class there @ 3.82 if i'm not mistaken. he then went completely back through it and ran it at sandfest this summer and was the fastest thing there...on sand i think it ran high 3.8s and low 3.9s. white knuckle would know the numbers for sure.
68mm bore cub, white knuckle billet head, cr 125 reeds, lock up with billet basket, 286 straight cut gears, 2-5 neutral down override, 41 pwk alky carbs. this bike is nearly brand new with the exception of wheels. +4 lrd chassis, marvin shaws front and rear, +12 lone star swing arm, jj&a billet axle, new white knuckle fuel tank.
if i can remember anything else i'll let you know.
thanks
