from vfr750fl to trx850

 
My VFR750fl project thunderbike racer is put on hold here is my new project! something else to tinker with in the shed a trx850!...inspired by a very rapid thunderbike trixie by the name of Michael Simmons of west country windings I will try and emulate from scratch. The trx is very light, can be lightened further, handling improved by an R1 front, stiffen the rear by putting a yzf750 swingarm. I have these in the waiting. I will probably lighten and balance the crank, peened rods, raise compression( bigger pistons maybe), put some FCR41 carbs, free flowing exhaust, cams re-shaped and make the crankcase breathe to help it rev easier...things Ive picked up from my tinkering with the vfr and my cbr640 and from the thunderbike racer above.....aiming for the bmcrc thunderbike sport class power to weight 1bhp to 1.81kg.
I should be able to get 85bhp relatively easily, then gradually make my way up to 100bhp at the back wheel.
