Hello, i'm new to the forum and the sport so hello.

I have been riding bikes since i was 4 and for my 17th birthday last week my dad got a 2000 Beta Rev 3, very exciting. We had a major disaster though, the throttle cable came out its lug under the fuel tank and jammed and when my dad started it, it revved its head off, like a chainsaw. It doesn't have a kill switch fitted, so we tried to stall it, but failed and it drove itself into the shed, then we tried to get the plug cap off but kept getting electric shocks, and eventually the piston picked up on the barrle and it stopped We have been thinking of all the ways we could have stopped it now and both feel really stupid, but whats happened has happened and we just need to fix it.

So the front wheel is badly buckled and it needs a piston, rings, replated barrel a new front rim (32h) a spoke nipple and a KILL SWITCH now which is going to be dear, but I thought i might ask here if anyone can recomend a decent place/places to try for new parts. Any help would be greatly appreciated.

Other than pulling plug lead, one good way to stop a revving bike is to disconnect the fuel pipe into the carb then (if possible) put in a high gear and try to ride it till fuel runs out - wont take long - not easy but will prevent seizing.

Anyway go directly to Lampkins for bits - v fast delivery and best pricing.

Good luck...

Plug the exhaust with a rag -glove or hold your boot over the end - this is the only way to stop a bike that is stuck wide open.

This applies wheen overreving because throttle stuck or down on the ground

Yank the throttle cable sideways out of the Domino housing. The cap will pop off, and pulley pop out and may give you enough slack to bring it down in speed.

Even with a kill switch, they can overrev and go into glow plug operation, don't need spark. Pulling the cable or plugging exhaust can bring it down in speed enough that the combustion chamber cools and the kill switch has an effect again.

tip it upside down to flood it.

There is no doubt there are countless ways we could have stoped it. So bloody annoying.

Thanks for the advice, I will check out lampkins asap

You can get the barrel re plated i'm not sure if lampkins do an exchange service

on the barrels .There is a company called Langcourt engineering that do

a replating service,they advertise in the tmx most weeks.As for a piston

as siad just go to lampkins they will have all the bits in stock you will need!

Try cental wheel for a rim found them to be cheapest they will also lase it up have alook at the web site

I have actually made some progress with the current wheel. I removed the rim and stood on it/bent it back into shape, relaced it and trued it up. It looks ok now, just has a fairly noticeable flat spot (perhaps 4-5mm inwards from the rest), but I don't think you'll notice it when riding. I'm gonna put it back on and see how it fares and if needs be replace it when it goes out of true. Atleast this spreads out the financial damage of the incident.
