1982 suzuki gs650glz won't start

[RedZed]

So I took off the fuel filter and cut the lines a bit shorter and it fired right up! I did a benchsync and the bike runs great! But then the battery promptly went bad haha. I figured from all the use from trying to start it a lot the past few days it just ran down completely.

Yep, don't go far till you know you got a reliable charging system. At least do a quickee test......

Better to find out in your driveway than in the median of a busy road!

Funny you mention.. I rode it around the block, stopped to fill it up and the battery was dead. I had to jump start it and I rode it home. I took the battery to orielly auto and they charged it and "said it was good" it was late so I didn't put it back it. Next day I put the battery in and it didn't start. I tried it for a couple minutes and nothing so I came back to it later and I put my tester on the battery and it read 11.6v and when I was turning it over it read 6.7. But it wouldn't even start when I tried to jump start it. I checked the spark and it's sparking. I am so confused.

Battery is toast in my opinion as it doesn't sound like it's holding a charge. Get a good battery and then run through the stator papers.

Probaby not charging correctly either if you couldn's start it after riding a bit.

How did you jump start the bike? Hopefully it was with a battery that was NOT attached to a running vehicle.

If you used a running vehicle, your R/R is likely toast, too.

.

[tom203]

Yeah, jump/boost only from non running vehicle! Despite O'reilly's test, I'd say your battery is toast.

[RedZed]

But even if the battery was toast wouldn't it still start if it was jumped? And pardon my forum language inexperience, but was is r/r?

[cowboyup3371]

R/R = regulator/rectifier

[RedZed]

Okay, I doubt that is fried. But let's say it is for the sake of finding the problem. Would that stop a bike from starting at all? Even with a different battery hooked up?

[RedZed]

Okay it has to be a fuel problem again. Because it started this morning but it didn't stay because when I rapped the fuel just slightly to try and keep it going it just sputtered out. But I do think the battery Is going out as well

[tom203]

This is likely a combo plate of issues- you got to knock them off methodically. Make sure gas gets to carbs-(understand how petcock works)

[RedZed]

I know that the gas is getting to the carbs, I've checked all four carb bowls and unhooked the fuel line and gas shot out from the petcock. And I had the bike running. It started probably 5 times. Then I rode it around. Stopped for gas. Battery was dead. And it hasn't been the same since.

+1, you have work to do. Adjust the valves first, dip and completely clean the carbs correctly, new orings everywhere, vacuum synch them and do all of the mixture screw adjustments, then test the charging system and fix what needs fixing. Then go right into the brakes, suspension, all of the other stuff, it is all certainly neglected just as bad.

[tom203]

OK, your carbs have gas- so when you crank it ("choke" full on, NO throttle input) ,got spark?? if yes , crank some more, you should see traces of fuel on plugs after a liitle cranking
