Thanks a million lads for all the replys, at least now I have a couple of options ( instead of hoping around with a panicked look on my face !!!!)

Folks, Apologies if this has been dealt with before but I'm new to trials. My 10 year old son and 14yr old nephew are riding beta's in junior divisions at the moment. We've had a few instances of bikes getting stuck on full revs ( for a number of reasons, (dropping,caught cables etc.)On a few occasions the engine kill button doesn't work ( I presume because the engine is so hot at that stage. Can anybody tell me what is the best method of stopping the engine when this happens ? Some suggestions we've heard are "turn the bike upside down", "Rip the carb off asap" or "block the exhaust with your hand and choke the engine" Any help would be appreciated, Thanks

hgas, Might be too simple but If there is an air leak between your carb and the head your bike will rev like that, (happens on my 300 pro) you might have a small crack in the rubber around the clamping area for the carb. A real easy fix ( so fingers crossed that's all it is), best of luck,
