More non progress :-)

Skim about 1.5mm off the head if you can without touching valve seats, that will give loads of compression, dont use an "advancer" and use superunleaded, lap the valves in (1mm wide seats if you can recut them at home) , advance the exhast can a couple of degrees over the now retarded cams due to the head skim. check for clearance just before top dead centre on the exhaust stroke and exhaust valve, use the original airbox without filter and rejet to suit. Skimming a big chunk off the head will actually retard the cam timing and give more top end power. The compression will give more everywhere. Will give you a good bit more top end go like 15 hp or so and have better midrange too and be far crisper and angrier off the throttle with fast pickup.. Dont use cheap petrol! Fit colder plugs with slightly smaller gaps.

There's a really obvious joke to be cracked there.

But I'm not one to lower the tone like that.

I was going to post something, but thinking about it would give me nightmares for a month.

Yeah, and I totally didn't think that anyway....

Have you seen the size of his ratchet ?

"Yes, I see your point."

"Why, have my trousers fallen down?"

"Help, Eddie - we're stuck in a Bermuda Triangle of knob gags."

Baby, it's the size of my screwdriver you've got to worry about.

How true, not only is it huge, but you're not scared to use it....
