GS750 only starts with starting fluid when cold

[ZinMaker]

Hello,

I can only get my bike running with starting fluid, then runs fine, until cold again, and then I have to start with starting fluid. I've read lots of posts and have cleaned the jets everything looks real clean in the carbs, didn't see any gunk, even when cleaning the pilot holes with the wire from a bread wire tie stripped of the paper. Any help will be appreciated. My bike is a 1981 GS750ex with about 68,000 miles.

Thanks

Welcome zinmaker,

I had the same problem with my 650 Kat.
The solution was a good carb cleaning step by step , following the carb clean up series in the homepage, and a new batery.

Good luck.

Eliseo.

P.S.: did you chek the cherging system?

Same here. I even took the carbs off and thought I had cleaned them but it still did it. I had to follow Earls carb cleaning 101 to find out there were places that goo be hidin.

It's much better now.

use gas treatment into a few tanks of gas and it may do the job.


NOT CARB CLEANER 8O

I have the same problem, and I've been told a few possiblities (I've got more problems than that if you care to hear 'em ) One solution is, yes, clean the carbs better. another could be a leaky intake manifold. post back if you find it, eh?

[ZinMaker]

Yes I also have brand new battery and when cleaning all the jets, also squirted some chem tool carb cleaner. Oh well, I do have taking the carbs out down to a science in about 20 minutes.

I have the same problem with my GFs 81 GS650GL. I just discovered that the two inboard intake boots are leaking. I will fix that and hopefully that will correct the problem. One clue to a leak is that the idle sometimes is erratic. How does the bike idle once started?

In the bottom of the float bowls are the passages that supply fuel to the choke circuit (that hole in one corner). If even 1 is plugged it will labor to start. Make sure you can blow carb clean through them all, but be careful: it comes right back on you if plugged (wear safety glasses).
