jamierxs100 Posted June 7, 2012 Posted June 7, 2012 All has been well for the past few weeks, and I was thinking last night it was time to sell the car. This morning it started first kick, but lost power after a few minutes, then I couldn't start it. I just went out and started it, (on film) and it cut out in neutral. - see link Not sure what to think, it wasn't sounding that great in idle either. Any help is very welcome. http://www.flickr.co...t84/7163501369/
Moderator Airhead Posted June 7, 2012 Moderator Posted June 7, 2012 Try it with choke and let us know the result Jamie
Moderator Airhead Posted June 7, 2012 Moderator Posted June 7, 2012 ok try with the fuel tap switched off until it runs out of fuel
jamierxs100 Posted June 7, 2012 Author Posted June 7, 2012 ok, ran it with tap off. ran for about 5 seconds and then cut out as expected. should I try it again with tap open? its got about 1/2 a tank of gas.
Moderator Airhead Posted June 7, 2012 Moderator Posted June 7, 2012 did it run well until it cut out?
Moderator Airhead Posted June 7, 2012 Moderator Posted June 7, 2012 well then you will find that your carb is over filling check the float height setting check the float needle is free to move maybe before any of this, give the carb a tap with something like the wooden stock of a hammer just in case it jolts something free
jamierxs100 Posted June 7, 2012 Author Posted June 7, 2012 Thanks, will look at the carb when the rain stops. It ticks over quite well in idle but every now and again the drops a big chunk of revs, then picks back up, but doesn't seem to have the same sound as usual, bit more spluttery. when I rev its not really getting the power, then sputters a bit more and loses it all together. want to use the word 'misfiring' but I know thats a technical term, but thats how it feels, like its misfiring. Cleaned and checked the carb a few weeks ago and its been super fine since then.
jamierxs100 Posted June 7, 2012 Author Posted June 7, 2012 just checked the spark plug, its black, wet and oily. the plug was new 4 weeks ago. think this will cause the misfire i've been getting.
Moderator Airhead Posted June 7, 2012 Moderator Posted June 7, 2012 fit another and start the bike, switch the fuel off and rev the engine freely to clear the flooded crankcases...when it dies switch on the fuel, then off again and re-start the engine and repeat another couple of times
jamierxs100 Posted June 7, 2012 Author Posted June 7, 2012 ok, changes the plug, and followed steps above, it seems to be working fine. Think the new plug shows the problem was the misfiring. But what has caused this problem should I be worried?
Moderator Airhead Posted June 7, 2012 Moderator Posted June 7, 2012 nahh its the joy of owning an old stroker Jamie...wouldnt have it any other way would we get a few spare plugs in stock and always have one in your jacket pocket with a plug spanner
