Squish clearance for a cool running mk1? (+plug Q)

[billy]

I want the thing to run as cool as possible, so no huge compression I guess. But I've read somewhere that a tighter squish gap CAN sometimes make it run cooler. So I guess I'm asking, what squish clearance would be best to use? Bike's gonna be used more like a fast moped to wizz around on, rather then a W.F.O.T track bike.

Bike is standard except running premix and a k&n style filter. (jetting will be dealt with asap ufcourse)

I might aswell ask, what spark plug would be a good choice?

0.9mm squish clearance and run a BR9ES or a BR10ES

Thank's mate! Will be looking for a plug then as the previous one was a BPR5ES.

Edit: If I can't get hold of a BR9ES or BR10ES, can I use a B9ES then?

b9es is fine...just remember to use a resister plug cap...

what is the worst thing that can happen from using a non resister plug cap and non resistor plug?

apart from making the occasional tv go fuzzy could it damage the bikes electrics?
