thanks for your reply I think you are right I will give the power valve a clean up.

Thanks for the reply, yes I can hear the power valve turn when ig on sometimes it is a bit sluggish. The plugs are new and I have set and re-checked the gaps all seems fine there. I think i will take the power valve out and check/clean it to see if it has gunked up? I had a powervalve about 15 years ago and never had a problem so I'm a bit stupped. I'll give it a go this weekend to see if it improves. Thanks again muff

Hi to all at the club. I have recently bought a 1988 RD 350 power valve. It has been running OK but recently when off the powervalve 0-6500 rpm it mis fires and there is little power as soon as I get it on the power valve it goes like a rocket. I have removed the carbs, cleaned and reset, I have checked all the ignition side and given it a full service. Some times it drops on to one cylinder gor 4 miles or so then comes back on. I cant seem to cure the problem. I am not sure if it needs a de-coke or if there is something else I should be looking at. Can anyone shine some light for me and point me in the right direction. My local dealer has all the attributes of a highway robber, I just dont want to got there. anything would be appreciated so I can get the old girl back on the road before the last of the good weather (thats the little bit we had) has gone. Cheers. Muff.
