To go back to the timing question, I think even if all the standard electrical parts are required by the 2010 rules to be retained, it's still too easy to cheat by filing the trigger on the flywheel and advancing the ignition that way (albeit by a fixed amount throughout the rev range).

I think that the standard ignition architecture should be retained, but advance curve and timing trigger should be free, even in Class B. This would allow any igniter boxes to be fitted, and the trigger could be played with.

Getting performance gains from this rule would depend on careful work and testing more than ££, so it fits with the DD ethos.

EDIT: I believe that the thing that stops 583's performing is the piston/valve/head combination, so pursuing performance via timing alone is going to produce small results. It would be interesting to do some research...

Provided you know how to do it as opposed to have to pay someone else to do it

Please don't change the rules for next year too much!

I'm in the process of getting a bike sorted for next season and it's costing a small fortune as it is! I don't want to have to make changes as well.

Spot on, the valves and ports, together with the combustion chamber are too small to pull enough gas through to make more than about 52bhp. Fitting 620 heads and pistons apparently makes them fly!

So...

Tyres - leave it
Pistons - copies of OE
CDIs - leave it

Job done.

Move on and race then....it was easier in 2007!

So much said with so few words. Genius.
