Stalling Issues

odie · 07-09-2012, 12:05 AM

I have a '01 GZ with 10,625 miles that I bought used. I had fixed it up and it had been running good up until now. I had taken the gas tank off to get rid of some dirty gas and when I put it back on it and refilled the tank it had trouble starting and running. It will start and idle with the choke on for a minute or so but then it dies. With the choke off it will stay running if you give it some throttle but when I ride it and I roll off the throttle to slow down, it dies. I have heard that of air flow problems can cause such issues and the bike does have a gap where the exhaust pipe bolts screw in due to a crack from the previous owner and so the exhaust pipes won't completely tighten; however this hasn't really caused any trouble before so I was wondering if this had anything to do with it or is something else wrong?

Try the idle screw on the carbie, or carbie could be abit blocked up from the dirty gas. Either way, a clean wouldnt go a miss. I have to get around to doing mine.

And add some barrymans B-12 or Seafoam in the gas tank with the fresh gas, bout half a can .

I couldn't get it started the other day but I took the carb off and found two clogged jets so that my have been the problem but I will try adding something to the gas too.

You'll find that the carb is the Achilles heel of the Gz. Frequent doses of carb cleaner in the tank, after you've cleared the jets, will help in a big way. I can't get carb cleaner, over here, but adding a fuel additive that is advertised as cleaning the carb & valves, has kept it running perfectly for the past five years. :2tup:

The dose of that stuff is 1 oz/gal of gas, maybe go up to 2 oz/gal as an initial treatment. Too much of either will make the bike run like crap. More is not necessarily better. Add it to every 3 or 4 tankfuls depending on how much you use the bike.

Sorry it took so long to answer. I got it running good after cleaning the carb and using a 4 ounce bottle of Red Line complete fuel system cleaner (the only thing the store near me had) in a full tank of gas and adjusting the idle sped. Thanks for all the advice!
