The MW80 dynoed at 20bhp - we got it to 25bhp with just a little bit of work. They also weigh in at 85kg, it's easy to shed 5kg off the bike but might be easier to get rid of more from the rider.........
Chassis Mods
The rear
sub frame under the seat can be removed and replaced by much lighter supports - saving about 3.5kgs
of wieght
The front forks can be made a little stiffer with less dive by putting 6 x 10 cent pieces under each of the spring caps and about 15ml more SAE 20/50 oil into each fork leg
A front fork brace can be added if required
A spacer of about 1.5mm inserted into the rear shock increases stiffness, but it also increases the rebound rate too, the real answer is to replace the shock totally
About 25 small brackets can be removed from the frame saving about 0.25kg. you can also bin the tank hinge mechanism and catch, saving another 0.5kg
All of the standard plastics can be replaced with fibreglass saving a further 2.00kg
Replace the front brake hose with a braided line
Replace Dunlop TT900's with something sticky!
Engine Modifications
Bin the round slide carburettor and replace it with a Keihin flat slide - Add 1.0hp
Port the barrel gently - Add 1.5hp
Use V Force Reeds and block - Add 1.25hp
Make sure that the compression ratio is 12:1
Use AVGAS RF100 - Add 1.0hp
Cleaning the inside of the expansion chamber and repacking the muffler seems to improve performance
Other Possible Mods
Use a 410 chain and turn down all of the sprockets to suit - this will reduce drive train losses
Replace the front disc with a bigger one and remount the caliper - removes brake fade
Put on a Vortex electronic ignition
If want to change the geometry you can change the headstock and triple clamps, but we never saw the need
