Motor
Bored to 102mm with a JV 10.5:1 compression piston. Exhaust port have
been honed and cylinder has been ported, polished and bench flowed. Valves
have been shortened and heavy springs installed for better seating and
strength. White Brothers Road Race CAM has been added also. Rather than
running Race Gas, I use '76' 92 octane with Pro-Power fuel addative. MUCH
better than PJ1. Jagg Oil cooler was also installed. Rocker arms were hard
faced.
Note: White Brothers hop-up kits do not suggest hard facing the
rockers. SO, MAKE SURE you hard face them!
Carb
Kien 41mm FCR Pumper..... Tried the Mikuni 41mm Flat-side, but was
not overly impressed.
Exhaust
White Brothers oversized header and e-series exhaust. Heat wrapped
to remove heat from the front of the cylinder and improve exhaust gas flow.
Wheels
17" front and rear Sun rims, stock XR hubs were used as they are lighter
than Talons. Traditional 3.5 front and 4.25 rear. Black Anodized wheels
for effect.
Suspension
Lowered 2" front and back. White Brother Lowering kit was installed
with heavier springs to suit a 200lb rider.
Brakes
Tried the front 320mm floating rotor. In all honesty, not required.
I found that under heavy breaking (two finger breaking) the rear wheel
still gets light and steps out. Stoppies are still as easy as pie with
the standard XR rotor.
Gearing
15/44. And she still lifts the front end in second! In third if you
tug a little. Max speed is around 115mph
Future Work
1. PC fans will be installed behind the head/cylinder. One on each
side to improve air flow. As you can appreciate, air flow behind the cylinder
is effectively non-existant.
2. Larger Oil cooler to be installed. Possibly fit one from a GSXR.
3. Scotts Steering damper
4. Inverted front forks off of CR250 97/98 model.�
