The motor at present does not seem to produce significant extra power at higher revs. Max power in it's present guise is around 6000 with peak torque at 4000. I rarely need to take it over 7 as there is enough below and taking it over does not seem to be any major advantage.

The importer Tim says they respond well to a better breathing air filter and removing the cat from the exhaust releasing the top end. He seems to know what he's on about as he races his in SM1 class with little other modification. I think both Tim and Pokenhood from Nottingham have got them 'to rev like a sewiing machine', but don't think I will bother with mine until I feel the need.
