R1 Clutch & Gasket
Before I fit the engine, I thought I'd take the opportunity to change the clutch.
Is a std clutch sufficient for a BEC, or should I fit an uprated one?
Where's best to get a clutch and gaskets? Direct from Yamaha or is there anywhere decent on line?
Cheers Steve.

Double up on the spring.
Cheap enough from your Yamaha dealer.

Doubling up on the diaphragm spring is the cheap way of doing it and seems to work. Alternatively there is the Barnett spring conversion at ~£100
which converts it to conventional 5 coil springs. I think this should give better pedal feel and allows you to add stronger springs if required, but
obviously costs considerably more than a second diaphragm spring!
As to plates etc, the standard Yamaha ones seem as good as any, not heard any horror stories or anyone saying Brand X is significantly better.

I've went the Barnett route. I wanted a bit of a heavier feel after driving the cerb for so long. I've kept the old diaphram just in case
of emergency!!!

Yep me too, ISTR reading comments that the double diaphragm spring setup can sometimes be unprogressive across its range so can lead to a slightly
snappy clutch take up, but I have no first hand experience of that.

As far as I'm aware, my motor has a stock clutch in it. It has had 3000 miles of pretty hard use, including a track day two days ago and is
still going strong!
Don't be so keen to ditch the stock spring until it gets tired..... 
Spin 'er off Well...
