Re: Bad Gas or Jettining issue???...FIXED
If your tank wasn't full when you put it away and it is not in a climate controlled area then you probably have condensation in the gas... once the water is out it should be fine I know it could be spooge in the carbs from funkified gas, but my experience with carbs on an old bike when I did not know to put stabil in the tank over winter tells me it is more likely water.... unless you don't ride it for 6 months or more degrading gas probably wouldn't be that obvious... a little water in the gas will be a problem
some may say I am wrong... but I had an XS 400 and I never put stabilizer in it... but I always gave it a full tank before putting it away for the 4-5 months of ice.... but I guess gas can go bad in as little as couple months
I'd bet if you had drained out all the gas and put in fresh it would be fine too...
and if you put stabil in a 1/4 full tank, you could still get the condensation. but I berlieve sta-bil now has a drying compound in it too so perhaps that wouldn't be an issue.. I believe seafoam not only removes moisture in the gas but cleans too so it's hard to say what the exact cause was here..
But as mentioned... if you aren't going to ride for a few months... toss in the sta-bil fill your tank fully and you're good.
Thanks for the advice and replies here is how it turned out-
last nite I added half of the can of seafoam and about 3/4 gal of gas...the tank was bout empty. I drove 32 miles at a low rpm where it was cutting out and running rough.....no change. I let it sit 18 hours...and then rode today...it ran about the same for 4 miles and then I turned around, by the time I was back home it was idling, but rough. I turned the idle up to about 1600 rpm and it was good... I rode agian a few miles, tunred the idle back down and it seems to be fine. I then rode the way it should have been all along...yep I should have added stable last fall....I appreciate your help.
Have a good ride guys.
