[QUOTE="Champ"] "big bang" theory does disagree with Darsy's assertion.[/QUOTE] I know. I'm going on experience rather than theory though. [QUOTE] Perhaps it's more to do with the throttle response? Dunno, to be honest.[/QUOTE] Could be. Could be the geometry of the bikes concerned or something. I just know my ~45bhp SZR used to do it all the time, and I only seem to get it on the 'blade when there's standing water or a bit of diesel or whatever. I can't remember my Bandit doing it much at all, even on much less sticky tyres - the OE Macadams slid a lot in the wet, especially on manhole covers etc., but I don't remember them spinning up. Could have been me being ham-fisted after recently passing my test, of course.
