Start problem

[suzuki750]

Stabilize my 83gs750 at the end of the season went to start it yesterday has a brand new battery cranks great just won't start somebody mentioned to me about draining the carb bowls then use prime to get some gas back in there from the tank

[rphillips]

Yep, that's what PRI is on there for. Personally I don't see the need of draining the bowls first, PRI for a couple of min. then it should start. Don't forget to put back to ON position. Leaving it on PRI could cause gas leaking into crankcase.

Yes, the bowls are likely dry from sitting all winter. Typically, put petcock on PRI (prime) for 20-30 seconds to fill the bowls, Then turn the lever back to ON or RES (reserve). This will work better for you with the bike on the center stand.

Did you have the choke on full when you tried to start?

Resist the urge to twist the throttle when trying to start.

If still no start, I'd move to checking spark.

What model 83 GS750? E, ES, S, or T? .

And, we like Pictures.

Yes I did have choke on I'll try using the prime thank you

different tail

Well...Did you get it started??? that's what this thread was about.

[suzuki750]

i drained the bowls and put it on prime for 30 sec tomorrow i am picking up new plugs got a new battery we will find out tomorrow

[Rich82GS750TZ]

Orrrr…. You could just pull each plug one by one, put it back in the cap, lay the plug threads against the head as you press the start button, and witness if each plug sparks or not.

[suzuki750]

ok.. new battery, new plugs drained the carb bowls primed for 30 sec to fill the bowls a little starter spray and bike is running like a champ

[Rich82GS750TZ]

Glad you seem to have it sortied. But if you didn't check the old plugs for spark, you don't know if your issue was not enough and/or old fuel, or 1 or more plugs gone bad. I'd want to know. You should not have needed the starter fluid. The fact you did leaves me wondering if you have a fueling problem/ gummed up carbs. Any more hard starting after this would have me tearing down the carbs for a full dip/clean/new o-rings. Report back after you have consistent starting and running w/out the aid of the starting fluid.

[suzuki750]

yes i agree.. should have checked the plugs first ...the plugs did look like *@%^$*@%^$*@%^$*@%^$ they needed to be changed and the little gas that did come out of the bowls was a little dark that needed to come out so far so good bike runs good and starts right up .its a very cold running bike always was

[rphillips]

Draining the bowls certainly didn't harm anything. But I wonder if draining fuel from the bowls, that has been sitting there since last fall, then refilling them with fuel that has been sitting in the tank since last fall will accomplish much. But in your situation I can see do whatever you can think of to get this thing started. You did good & probably all will be fine. Congrats.

[suzuki750]

Believe it or not the gas in the tank look much better than what came out of the bowls much clearer it did have stable and seafoam in it and there wasn't a lot of gas in the bowls either so I'm not really sure what really did the trick either but bottom line is I'm riding

[Who Dat?]

... .its a very cold running bike always was

Try turning the pilot screws out about 1/4 turn on each carb.

When is the last time you checked valve clearances?

With clean carbs and good valve clearances, these bikes start quicker than some fuel-injected machines.
