Sorry didn't realise that lineaway.

Good evening I've recently had the same problem with my 2007 beta rev 3 . It sounded exactly the same and smoked the same . I checked threw all the electrics . On the cdi i found a bared wire which I heatshrunk and taped . I also found a loose wire from the block connector which connects the cdi to the stator . It wasn't hanging out of the connector as there is 2 wires in the block it was wedged next to the other wire until I gave it a gentle pull . I cut the block off and put new connections on and also heatshrunk them . Then the next problem was the wire leading to the coil was loose in the block connector so I cut that off and put new one on . I also cut a tiny bit off each end of the spark plug lead to ensure good contact. Put new spark plug in and cleaned spark plug cap out with contact cleaner . I've rode the bike 3 times since this and it hasn't missed a beat . It would start fine but just back fired and popped at quarter throttle . I'm unaware of which part sorted it as I did the things I mentioned in one night but they were all things that obviously needed sorting. It was all worth a try before ordering a cdi which I put the problem down 2 . All I can say is check every connection

Hi guys My Dad has just bought a scorpa sy250 with the vin number vmuscy249sc600 can anyone tell me what year bike this is

Thanks 0007 i put a new needle float valve in about 3 weeks ago as the old one was really worn, but didnt use anything on it to seal it so thats maybe worth ago

Hi guys why is it when my 2007 rev 3 is upright i dont get any loss of fuel , but when i leave it on its side stand idling for 5 minutes or more it starts leaking, not loads but leaves a little puddle

Hi guys Im looking for someone to rebuild a shock on a 2007 beta rev3 sometime in the next few weeks as its leaking , does anyone have any good recomendations of were i can send it to be done.

Thanks for your advice guys , tonight i have cleaned the carb , ive also cleaned the airbox which had abit of water in it so im going to look at sealing it abit better to prevent water from getting in , hopefully the carb clean will of solved it as a few particles of dirt came out.

Zerorev3rev4- Ive repacked exhaust and clean air filter before every outing , is a crank seal a big job if it is that , last time cleaned carb one of the jets had water in it

Hi guys , My 2007 rev3 seems to of started running rough after 5 minutes of warming up there seems to be a clunking noise but the bike seems to run fine , after a hour or so of running it doesnt seem to idle properly , it just wants to cut out , Ive tried new plug , cleaning the carb and trying v power fuel
