Kiwi Paul & Sparky,

Thanks for the info!
I plugged 3.70 into my bike rpm/gear/mph calculator and came up with extreme drag racing gearing.
hmmmm...
Probably excel is broken on my laptop (its a Mac) :-D
or I don't have the car's tire circumference right.

I'll figure it out

Karl

Karl, you Mac is right... remember the primary reduction in Bike motors and less than 1:1 tranny, even with a 28 inch tire needs a 250 rear to go fast

stainless,
you never know what my left-wing Mac is gonna come up with :-D

18/40 on my Busa = 2.22,
Sparky gave: "3.42 3.23 available  and  with a 2 series carrier 308 2.73 2.56 2.41 2.28 2.14"

so it looks like the waterfront is covered.
Anyway, you and others are running the GSXR & Busa motors, so I knew there was a way to do it.
This is fun!

WTH didn't i get the circumference from the blue CC?  dumbo me.

Don`t ask me either...Seems I remember that a 28'' tire wouln`t fit with the rear suspension the way it is. Think there is a 26" Frontrunner on there. Coudn`t swear to it, though..... :? :cheers:

Ask him what rear-end they are using and how they are driving it and if they have made gearing changes  :-)

If you make gearing changes it is much simpler, less expensive and quicker to do it with sprockets or quick change gears vs. different rear-ends.  We have done it with the transmission gears, but the transmission wasn't that cheap, but once bought the gear sets aren't that expensive.  We will probably make a rear-end change for next year and then fine tune with the transmission again.

......This is fun! Karl

Yes it is, enjoy,
