My Concours carburetors give me a fit sometimes.if I let it sit up much at all, it starts running rough. Always the cylinders on the left side. It seems worse if I leave it on the sidestand instead of the centerstand. I use Seafoam and that usually clears it up. One of the bike mags recommended something called Star Tron gas treatment. Anyone try this? I was reading Rider magazine in the tech advise column about a Connie rider with the same issue and they recommended a complete carburetor rebuild. According to them, a little seal on the float needle wears out after a while causing problems. His bike only had about 15,000 miles on it, mine has 61,000 miles. I have tackled single carburetors but not four and feel that is over my head. Who do you trust on this, a dealer or individual? I don't want to pay for a rebuild but just have someone dump gas treatment in the tank. What should I expect to pay for this? This problem in the past happens at startup usually. Lately, though it happens after riding a while. I always know it is going to do it if it is hard to start or if I am at a red light idling and the rpm's drop from 1200 to 1000. Some Connie owners say they sometimes have rust in the tank causing problems. This is on the older 1000 cc Concours.

Try the Star Tron. I have had it help sometimes. Most carburetors don't
like ethanol. The 10% helps avoid gas line freeze, but eats seals and
gaskets. BTW, Isopropyl is a better solution for anti-freeze. Find a
service station that sells gas with no alcohol in it and try a couple of
tank fulls.
Of course the real solution is to get a bike with fuel injection. I
first became a full time motorcycle mechanic in 1952 and have rebuilt
lots and lots of carburetors. Still do it in a pinch, but fuel injection
is the only way to go. If I could convert my KLR, I'd do it in a
heartbeat. I almost always grab my fuel injected bike if I have to go to
the store. Get on, turn key and ride off. No diddling with the choke to
get it to keep running. No extended warm up period. Just ride.
Been there, done that.

Yeah my Versys is fuel injected and I really like it (if I could figure out how to get to the air filter-heh).
A friend says carburetors is voo doo science.

Tony, living where you do, I predict you will soon want another KLR. Nothing against the Trident, and there are plenty of open roads around you on which to wring it out, but there are too many places the KLR can take you where the Triumph will be less than happy. Hey, there is nothing wrong with having more than motorcycle.

Have always wanted a brit bike so now I have one. Will continue to look for a another klr but at this point am looking for the new adventure. Will continue to lurk. Thanks to ya'll for the info for because of the list my bike was a good runner. Thanks to everyone and look forward to warm weather.

A bank of carburetors need not be intimidating. There is increased hassle
with removing and replacing them as a bank and syncing four vs two or none,
but what makes one carb work also makes four work. Guys on the GS Resources
forum do it regularly and help each other out. I'm sure there's a Connie
group with similar expertise somewhere out there. If you do dive in be sure
to not overlook anything such as intake boot o-rings or intake trumpets
etc.and be careful to reseal the airbox, carbs, and intake boots carefully.
Air leaks can make life miserable.
Best way to maintain carburetors is to add fresh gas to the tank, ride
until empty, and repeat.
