hi ive had an rs50 since feb and its on an 03 plate.

shes had an engine rebuild 2 months ago and has been running fine until now...

gets up to about 9000 rpm sometimes 10000 and just splutters along! looses power then kicks in and jus dies agen and it keeps doing it and the bike jus kangaroo hops along !

sometimes it will not start so you have to change the spark plug
when it splutters if you change the spark plug it will run fine for about 20miles but you can tell its not as powerful as it should.

ive cleaned the carbretta...checked the fuel feed...brought new spark plugs

any ideas guys ??

cheers ... Dan

do you get loads of smoke when it splutters?
Also what colour is the spark plug once you replace it?

well thats the least of my probs now lol
but before i cleaned all 3 of my plugs and wen i took them out there was a load of carbon on them
on it sunday and she broke down!
head gasket went so had to replace that
water had got in the barrel.
replaced it and brought new exhaust
still and not really noticed much smoke
as to my early problems wen i take out the plug now it seems perfect

its driving me mad now i love my rs50 !!!!!
