Carb problems

[Eric1966]

I recently bought a 82 GS750T that is in very clean condition, but ist has been sitting a long time, and the carbs were leaking fuel. My first thought was bowl gaskets, so I changed them, reassembled everything, and still leaked. So, I tore everything down (again) and found bad "o" ring on connecting tube. cleaned carbs, reassembled. Now runs like crap. Tore everything down for a third time, ordered K&L carb kits, installed, cleaned, set float levels and reassembled. runs better, but still like crap. wont idle sputters at all rpms. tore everything down again, installed new idle air adjuster screws I left out, set at 1 3/4 turns out, reassembled time #4. now bike idles exellent at 1000 rpms but if I ease into the throttle it sputters, and also sputters while holding steady rpm. also can tell its still sputtering at 70mph cause the tach is fluxing. When im stopped at a light I can smell gas fumes, so i thing its running rich?? but after becoming a expert on R&R of the carbs thru OTJ work im at my ropes end. Ant Ideas? The only thing I can think of that may be a culprit is the air jet that came in the kits were 170's and the jets I removed were 160'S

Thanks for any help....Eric

Sync the carbs. Unless the carbs are in sync, you might have one or more opening before others. This can cause one or more cylinders to get more gas than the others.

That can make is run poorly and might be the "gas smell" you're getting.

I bought an 81 gs850L model for $300 and it is still a basket case. Carbs: I finally got them running good but it took total disassembly and soaking in kleenflo metal parts cleaner for 20 minutes to get all the passages going again. If you go near this chemical you need to be outside with a carbon media respirator, nitrile gloves and goggles, the fumes are horrendous and it is very carcinogenic. I haven't sync'd them yet but I have no more off idle bogs or flooding. also had to replace all needles and seats with aftermarket ones to keep carbs from running over. Now I dealing with the faulty alternator. guess next time I'll save up and get something a little nicer shape. By the way, I have the mikuni carbs, the jets under the plug under the floatbowl; when I cleaned those its helped immensely but the soaking did the trick.
