Title: Hesitation - Clean Carbs?
Post by: Sier on May 11, 2008, 02:29:21 PM
Hi Guys,
I just wanted to say I just bought a 2002 GS500E with 2,250 Miles.. BEAUTIFUL BEAUTIFUL.. The bike is in REALLY GOOD shape.. and there's only one thing that needs to be fixed.
The bike hesitates a little when pulling the throttle.. It doesn't die at all after warm up, however if you pull the throttle the RPM won't go up for like 2 seconds... Just like it doesn't have enough gas.

The seller told me I have to clean the carbs, and I would like to confirm this. Do you guys think cleaning the carbs will fix the problem? IS there an easier way to  fix it? I don't have ANY idea on how to clean the carbs.. So I'm really lost.

Thanks Guys!!

I'm happy to be part of the GS500 FAMILY

did you try to adjust air fuel?

Cleaning carbs is really not that difficult. 2c

I bought some SEAFOAM and added to the fuel.
CAn I let the bike idle for 2hrs?
Is it ok?
so it can burn the gas+seafoam and clean the carbs.

Idling for two hours is a bad idea. It's an oil cooled bike, and it wants to be ridden with enough speed ( > 25mph) to keep air flowing over those pretty aluminum fins.

I'd start by draining the tank, then the carbs at the float bowls and trying fresh gas. If it still acts sluggish, check your plugs for signs of wear or mixture problems.

Bad gas (water/other) is usually a cause for problems, along with vacuum leaks, but this doesn't sound like a vacuum leak.

Also (possibly unrelated), from what i've heard, the best way to use seafoam or any of those kind of cleaners is to pour it in, then run it for a while, then let it sit so that the seafoam is in the system and can do the cleaning.

Worth a try as well maybe?

Welcome!

It sounds like a stock, factory lean carburetion problem to me.  I'd check the simple stuff first, like sun or age-cracked hoses starting around the frame-mounted fuel selector.

Thanks Guys!
I added some SEAFOAM + 93 octane gasoline..
It's running smoother now..
I'm going to get some plates tomorrow, and if I feel it's safe to ride, I'll ride..
If it continues to jerk/stall.. I'll just find a shop to clean the carbs.
Thanks,
I'll keep you updated.

you know 93 octane isn't good for your bike, right ?

you can clean the carbs yourself, they're very simple, and there are write ups here on the forum. i don't think it's your issue though. ;)

if you want to let the bike idle for a long time then find one of those giant industrial fans that blow at like 40 mph or a very windy place.

Will a GS actually idle for 2 hours without fouling plugs?
