I'll take another look after I remove them from the cleaner. The o-rings are on the very edge next to the slot for the screwdriver. There were no washers, and no springs are readily visible. Maybe when they are cleaner I'll see them stuck in the bore. I Googled this and found at least two different styles, one with washers and the o-ring on the shoulder, and one without and the o-ring next to the slot. It will be late next week when I reassemble them and continue. I'm convinced they were assembled this way in 1980 by Suzuki. I'll keep the forum informed of the results. Thanks , gs450sjip

Mine look like this:
I guess they are the non-washer style. gs450sjipComment

Cool, I will take a look at mine tonight.Comment

Looks exactly the same as the pic you posted. I have mine set at 2 1/2 turns out and the bike runs great. Once i get my tank patched i will do a proper colortune and vaccum sync on it and I expect it shoul really run. Great bikes.Comment

No washers in mine either... and exactly the same as that pic.
The spring is there to keep tension and prevent it moving I believe although I could be wrong.Comment

Bugger! Hopefully you don't have to wait too long and can get back into it soon...Comment

Pete, and All,
Just an update, I received the replacement carb body, it is exactly like the original. It also does not have a spring on the mixture adjustment screw. So , I can't say it's missing, that's three I have without springs. Doesn't seem to be an issue, the screws have tension on them without the springs. It's in the carb dip now. I may replace the valve cover gasket while the tank is off. Most likely next week before I restart it.

Weird... I have never seen nor heard of them without springs before! Maybe the earlier revisions didn't have springs? Anyway... good luck! Looking forward to the result...Comment

Pete and All,
It's back together and there are changes. I have the floats at 27mm, the mixture screws are set at 2 turns out. The carbs are clean, all passages are clear. It starts quickly, without choke, then settles into a smooth even 2800-3000 rpm ''idle". It stays there for awhile then slowly slows to 1200 rpm and the enrichener is needed to keep it from stalling. After is warms, I tried to rev it some which it does, but it hangs at the fast speed around 3000 rpm, it does not return to lower speeds easily. I am going to check the slack or absence of, in the throttle cable/twist grip. The exhaust does not burn your eyes as before, so it seems leaner. This is with the air filter and airbox lid back in place. Right now, I'm thinking/hoping it is a mechcanical issue, binding throttle, (I tightened the angle iron gang plate after I tightened the top covers and cable bracket) or not enough slack in the cable, lube the cable etc.. Once I get a consistant idle, I can adjust the mix screws.
The cam cover leak was fixed with Loctite 518 anerobic sealer without a gasket. I did not have much time to fiddle with it yesterday. Any advice is greatly appreciated.

It is good that you have changes but what you are now describing is a lean condition, a hanging idle is a sign of a air leak somewhere.Comment

hjfisk,
Yes, I agree, it is a possibility. I will check for leaks, It did not rev as before, seemed sluggish without power. I did hear a odd , very slight, popping or spitting sound on occasion. It was never there before, so I think I'll loosen all clamps, try to reposition the carbs, then retighten them.
Thanks, GS450SJIPLast edited by Guest; 10-17-2012, 06:00 AM.Comment
