Jetting.

[Guest]

Jetting seems fine till I let the bike sit for over a week or two. Then it takes a few rides around town to get back to normal.

Hesitates when cold at about 5k rpm's but does warm up after about 10 miles then after a day or two of riding the hesitation is gone.

80 GS1100E with vance hines header, K&N filter, and box top removed.

Been a while since I looked at the jet sizes specifically.

Wish I could find some non 10% ethanol gas to see if that is the problem.
Is thier and aditive that would help for this if the ethanol is to blame?

Seems strange! sooner or later, someone will ask about the jet sizes " specifically". Do you think you might have sediment sloshing around in fuel bowls? I don't see ethanol as a culprit.
I've used Seafoam on my son's ninja 250- mostly out of frustration- and I think it does something,but I know many folks are skeptical of any additives.
