Just the Wossner Rods would remove 200 grams each of weight off the Crankshaft:
.. 1lb. of weight off the Crankshaft .. and these long cranks need Weight Removal
as they Flex after certain power levels.
After 140HP .. 1200 engines start eating Rod Bearings .. so Blueprinting the Oil System .. shim the Oil Pump
to raise pressure .. have the crank_rods_pistons_flywheel & clutch assembly Lightened & Blueprinted & Balanced
at a Pro Balancing Shop is also Mandatory .. you'll enjoy the effects of the Crankshaft Lightening_Balancing greatly.
RB Racing has some info on their Kit for the K&N Air Filter replacements.
Install Larger Intake & Exhaust Valves.
Bore the Throttle Bodies.
If then .. you still desire Uber Power .. their TURBO kit is presentable ..
You wouldn't need the 105mm bore kit .. just the Wossner Connecting Rods ..
as you want Cylinder Wall Thickness to control the Pressure and the smaller
Piston will have less ROCK to it .. meaning higher RPM's.
If you like .. go with the Wossner 105mm bore kit when you order the Con. Rods
.. these come with bored & matched cylinders ..
Then get your Computer Software remapped .
As far as the Lightening Balancing .. use a Dedicated shop .. the Automotive Racing
community knows who is best .. Google .. call around to the Top Builders ..
Pick your most used cruised everyday RPM level .. that is what you'll have the
Engine Balanced to .. 3,000 RPM with a Harmonic of 6,000 RPM perhaps.
As you reach 3,000 RPM the engine will get way smoother .. as you run above it
vibration sets in .. same with reaching 6,000 RPM level .. so .. 2,500 RPM has
a Harmonic of 10,000 RPM .. the Wossner Lite Rods will remove big amounts
of Vibration .. less weight bends the crank less too .. think it over ..

Do Not Call San Jose BMW to do it as your Pockets will be SUCKED DRY of Money..
.. they will just send it out to the Shop YOU didn't bother to find out about and
charge you a whopping FEE on top of it.
I suspect that once you've done all of the Above WITHOUT the TURBO kit ..
YOUR Engine will be Beyond HPII Boxer Cup Quality .. it'll spin up faster & make RPM quicker
.. a ' Blip ' engine .. and Power Delivery will be such that you won't get KILLED
deep into some Highway turn forgetting that TURBO Bikes are ' Light Switch ' items ..
.. instant shrieking Banshee .. smokes the Tire at 70mph .. you correct & high side .. Adios.
TURBO Bikes are for Straight Lines .. louzy Road Racer.
