My bike was working great, then when reving it died and after that it wouldnt start. So I pulled the throttle and got it to go. Now its not starting at all, Im thinkin I fouled the spark plugs again. Its also in need of an Oil change could this have caused the bike to die while shifting? Tomorrow I plan on cleaning my brand new spark plugs and changing the oil. But before I do this I wanted to know if you guys think there might be something else I should do to fix it?

 

clean the carbs, air filter, new plugs, charge the battery

 

I checked my spark plugs two of them look good and two of then are dark and sooty, from left to right: good sooty good sooty. Should I go buy two new plugs to replace the dark sooty ones?

How do I go about cleaning my carbs and what sort of things would I need, after looking through the repair manual I can find anything other than the synchronizing them. A little more information would be helpful.

And would dirty carbs even be causeing what is happening to my bike? It cranks but doesnt start and ocationally backfires when cranking.

 

The backfire is from the fouled out plugs. I would only buy 2 new plugs (the wet ones). If it has done this before then you might have another problem. An oil change will not solve anything. How many times has it fouled plugs? Explain to me what you do when you start the bike. How long do you leave the choke on and do you rev it when its cold? We will go from there.

 

The guy at autozone said my dirty plugs werent foul, but that the fuel was running rich. However if they are fouled this would be the second time. When it was working I would not put the choke on, and usually after I started it I would back it out and go from there. When it stopped firing normally, I twisted the throttle to get it to fire. Now it doesnt fire at all.
