Personally, I think the biggest limiting factor (flame suit on) that limits the VFR is the size of the throttle body. FCR39's would do the trick. Get rid of those PITA butterflys too!

Bear in mind, the RC30 would break it's crank when pushed much over 140HP. The VFR800, based on the RC45, would be a better (but more expensive) platform. The last year of the RC45 in WSB, it was a 190hp, variable intake, semi-dry sump beast.

Don't mean to rain on your parade but considering the RCs thirst for oil, I'd be hesitant about hiding the filler cap (and the site glass) behind the fairing.

Firing cylinders together is generally known as a "Screamer" configuration....not Big Bang.... :twocents:

The screamer is an even firing order engine. Google Doohan and Screamer.

V4 2-Stroke (90 degree motor)

000----090----180----270----360

-1-------3--------2-------4-------1-

All cylinders fired within 90 degrees is now called the 'long bang'.

Long Bang - I4 or V4 4-Stroke

000----090----180----270----360

-1-3-2-4---------------------1-3-2-4

Congrats Rick!
