lean over & turn the fuel off or flick the kill switch on those type that turn off n stay off. Pays to do it to a mate though 'as we used to do at club days in our early days' [when life was fun]'--jeez they'd get 'mad' haha. Best one though [wrote about once before somewhere] was JN Roberts on the start line [in NZ] on his Husky & dropped the clutch to have it go 'backwards'. Great days back then. Changing tact slightly just thinking about 'rev limiters', my unit Metisse at a wet woodville mx, i had plug leads with no caps, just the steel bent clip on to the plug thing. Rained during the race & shorted to my leather pants at revs n had me doing a 'war dance' for the last few laps.
