December 1, 201015 yr Hi, im looking for someone with abit of know how about my model of trials bike, its a beta techno 250, I think its a 1997 model but unsure. Anyway, the problem is that a couple of weeks ago I was messing about up the hills where I live when I decided to stop and have a breather. Five minutes or so later I jumped on and kicked her into life when the revs took off out of control! I panicked and hit the kill swith but its abit dodgy and wouldnt work, I couldnt reach HT lead to pull it off so all I could do was turn the fuel off and wait for her to starve. Ive been too scared to start her since incase I damage her. Could anyone tell me what the feck went wrong and how I would fix this! Thanks for now.
December 1, 201015 yr It may be a very simple cure indeed On the handle bars, pull the rubber off the throttle cable and check that the cable is still in the throttle body. Do the same at the carb end of the cable. If the cable has jumped out, even a short amount, it will cause the symtoms you mention. If this is ok, you will need to remove the carb and see if the slide is sticking.

I hope thats it! now all i need is a ned back wheel as I noticed that for some reason there is a number of spokes missing!

December 1, 201015 yr Author Why not simply replace the spokes? hahaha, yeah I would as it seems easier to find spokes than a bloomin wheel but the holes on the wheel rim look abit knackered! Ill take photos at the weekend and stick them on here, I would like to peoples opinion as to what could have happened as I dont have a clue! watch this space.
