Gixer1460, I love the quote.
Duckndive, the 2005 and 2006 650 were oil cooled, after that they are water cooled. Looking at the specs for 600 and 650 bandits it appears the 650 has 1 bhp less than the 600, drinks more juice and cost half as much again for vehicle tax.
I just happen to have a GSXR 750 L and a GSX 1100 F both for sale but I've not had anyone even look at the 1100 so I don't think I'll fair any better with the 750. After reading in here that even a dumbf**k like me could put the 750 top end on the 650 base, I'm thinking I could get some extra bang instead of the hassle of trying to sell it. The b6, b650 and 750L the stoke are all the same 48.7mm, the gudgeon pins are the same diameter so it should all fit. I was going to put the whole 750 motor in the bandit frame until I saw the insurance quote.
