Hello, Im having problems with my engine at the moment, and its very Annoying. Its been De-restricted for a while so i dont think thats what is causing my problem. when i first start up my ped, it starts and runs fine to 50 mph. after a few seconds, the revs die slightly causing the bike to obviously slow down!. after it slows down to 30mph! the revs gain speed and return back to 40ish. my engine repeats this over and over again slowing to 30, then gaining speed..ex.. My bike will not go flat out again when i ride it. The first time this happed was after i cleaned my bike, so i don't know if water got into the electrical system but the engine have no electrical restrictor on it?.. the best way to describe this problem is like a electrical restrictor gone faulty. The bike also feels like its lacking low power, like coming of roundabouts of corners. if any one have had the same kind of problem or knows what im on about please get back to me.. would be EXTREMELY helpful : )

Hello, yes it was a proper clean!. i have clean my carb out several times before and after this. When you say change the plug.. what do u mean the electric device that connect to the carb?

youre carb has water in it

When you said washed it was it just a quick wash or did you clean engine etc?
Possible causes?
Possibly water in carb? clean carb out.
Plug HT lead or coil breaking down? Change parts. I would change plug straight away.
