The Limey
Evil English Villain
Why thank you old chap. It's very rare, so I'm keen to retain it. I've started painting the seat unit to match, which is going to be a major job of work!
I've been mulling the engine. As aforementioned, the barrels really need a rebore, gone beyond the potential salvation of a hone. A rebore means new pistons, which means big money.
Been reading around and the mid nineties YZF motor is very similar, but has a fraction less stroke and a smidge more bore. However, with the addition of a custom cut 5mm base gasket the YZF top end mates seamlessly to the FZR bottom end to give 660cc and, properly set up, just North of the magic hundred horsepower - ton up power for ton up performance.
This should also save me pennies as over here entire YZF (or FZR600R) too ends in good order can had quite cheaply, so I can get more edge for less wedge.
