So what should I be looking to change from standard? Springs I guess, anthing else?

Stock seems to be fine on the Busa with just uprated springs, a mate of mine is still running his stock clutch in a turbocharged busa putting out ~250bhp, although I suspect it will need uprating when he fully winds the boost up.

yip thats all i did as well,everything seems ok so far and it gets a little stick now and then

Was looking at this, but not sure if its necessary??

Further to the last question, just realised that the clutch is hydraulic. How is this operated? Obviously by a slave cylinder, but to connect a propshaft I have to remove this!

You need to remove some/most of the sprocket housing and space it out to suit. Assuming it's like the bird one.

Invest in a westfield megabusa one like i did - it goes against the 'locost' theme but is a lovely bit of kit!! Costs about 200ish quids.

Rich.

Errr no thanks!

Found a guy who makes billet slaves. £50!
