Mr.7/11's dynoruns
Stage 1 Measured on Ruud Fredrik's mobile dyno at the European Streetfighter Show '98
Standard untweaked 34mm CV carbs with separate K&N filters, BSM Vampire exhaust
124hp

Very unstable curves, but the red acceleration curve is way off. The engine takes too long to catch up so the throttle-response needs fixing.

Stage 2 Measured on the M.W.S. model 100 Dyno
Still the standard 34mm CV carbs with separate K&N filters and BSM Vampire exhaust
Goal was to set the 34's up properly and improve throttle response
126hp, 112Nm

If I remember correctly the figures meant; float level + 2mm, needle position 3 from top, 128 main jets, 2 1.5mm holes drilled into the bottom of the slides and +sl means whe added two breather tubes to smoothen the power delivery.
This shows the gain in horsepower trough the gears and the blue power curve.
A healty increase of torque along the range.
This shows how the throttle-response was fixed. Blue curve is how it should be and red how it was.
Stage 3 Measured on the Moto Mirage mobile dyno at the KicXstart Streetfigher show
29mm flatslides bored to approx. 34mm, separate K&N's and BSM Vampire
126hp
A very smooth 126hp. My first experiment with flatslides and it looks promising as they weren't even set up right.
Stage 4

Measured at HM-racing in the UK to set up my Mikuni RS36 flatslides
Mikuni RS36 carbs with separate K&N's, BSM Vampire
These graphs are in BHP and ft-lbs instead of SAE-HP and Nm!
Horsepower 133bhp / 135hp / 100kW
Torque 82ft-lbs / 112Nm

Trough the gears
Power curve
Torque (you can't whack the throttle fully open untill the revs hit 5000)
We tried raising the needle to get rid of the dip @ 4500rpm but it didn't work. Most probably caused by the exhaust system.
Stage 5 Measured on Moto Mirage's dyno
Velocity stacks on the Mikuni RS36's (no air filters) and a Laser ProFrace exhaust
140.4hp
Power up to a record- breaking 140.4hp!
 
Here my bike is plotted against a few turbo-bikes
Stage 6

"Final" configuration

- Mikuni RS36 with separate K&N's, factory settings
- Nikko Strada 4-2-1 exhaust system
- 3 degrees ignition advance by rotating the pickup base-plate counterclockwise
- one-off wiring loom with 14,1 volts at the coils

136hp @ 8724rpm / 125Nm @ 6519rpm


The bike got a bit too extreme to my liking. With the Laser/RS36 combo ran very rough at low revs but above 6000 it went ballistic! Also the exhaust was a bit too loud to my liking. Must be gettin' old ;-)

CV40 vs. RS36 Here's a graph from someone who switched from 40mm CV carbs to Mikuni RS36's
Power went up 5hp and torque 5Nm
