All this opens up many ????
Removing crank material changes the journal size. This means new 'babbit' bearings will be required? And the overboring of the cylinders? The walls are powdered metal aluminum composite. Not your 'run of the mill' easy to machine bore. Done wrong and can you say 'major blowby'? What about rebalancing the assemblies after all this work? Even then, all this will undoubtly affect the fine balance and reliability designed into the VFR800. How much HP are we taking about gaining? I remember the lead designer that was interviewed back in late '97 as it was being released stating many combinations of bore & stroke was tried until they came up with a 'happy motor'. Maybe there's some tuners out there that know more about Honda motors than Honda themselves, but all this time & $$$ might be better spent on making the bike lighter (remember 6 pounds per HP) and handle better. I find making bikes lighter /centralizing mass is more cost affective and yields better results than
major motor mods.
