possible fuel issue I believe

[Guest]

I bought the bike last month, didnt run, sat for at 10 years possibly a little more. Cleaned the carbs, just a basic cleaning ran great, I poured some Seafoam into the take let it sit and when I went to start it, it ran like crap. Only 2 of the pipes were getting hot, slow rev etc. So I figuered something in the carb got kicked lose and clogged a passage, I did another clean and replaced all the jets, main jet holder tube, float needle and holder with filter same problem. I bought a ultrasonic cleaner and let them go with some lemon juice because I didn't do a complete teardown and didn't want to mess the o-rings up inside there with some stronger cleaner, and figuered I could get away with just that. Still runs like crap, now only 1 pipe is getting hot and im so stumped, also the choke makes the bike want to stall, only started with choke off and I didn't even have the bike running previous. I shouldve just sent them out to begin with. It's got between 125-130 psi on each cylinder cold, without the throttle being opened because I didnt know that makes a difference, so Im guessing it would be more with the throttle open.

Could the diaphragm slides be a reason here? could possibly be hanging up inside the carbs? someone told me that could be it, but it ran great the first time without cleaning the diaphragm slides


Any help with this would be greatly appreciated

Well rest assured youre not the first that has tried to shortcut reality. They need a FULL tear down and NEW orings and gaskets. Heres the tutorial.

Heres some links to orings. Be sure to replace the intake manifold orings as well. the intake manifold is the rubbr boots bolted to the head that hold the carbs. GSs have a few different intake oring sizes so measure your inside diameter of the groove and order appropriately.

Here is a great website with lots of info and manuals specific to GS bikes.
