Hesitation HELP Please

[95GSGUY]

I know there are already lots of posts on this topic and I have read most of them, but here is my situation:

- Bought a '95 GS500 for a really good price.
- Right now it is problem free except for some hesitation right when I go to accelerate. After a couple seconds it picks right up and I am good to go.
- I am thinking that maybe it is the carbs that need cleaning, but I don't want to spend the money getting them cleaned if I don't have to, since I didn't pay a whole lot for the bike in the first place. I was thinking about cleaning them myself, but I think it might be a little over my head as I am fairly new to bikes.
- I don't know that it has always hesitated like this (for the last few months), so I am wondering if anyhting I have done recently might have affected it??
           - replaced air filter
           - replaced spark plugs with stock ones (apparently pre-gapped)
           - ran a cycle of fuel system cleaner
           - adjusted my clutch + clutch cable
           - adjusted choke cable
           - adjusted throttle cable
           - swapped new bars on
           - stock exhaust modification (drilled holes in end of pipe)

I live in Canada (BC), and we get a lot of rain in the fall, so I will only have my bike insured for another month or two before storing it for about 8 months. Is it even worth getting the carbs cleaned right before storing it?

So given all this info, any tips would be greatly appreciated.

i'd just run it with some seafoam additive in the gas for a while and see if that does the job. it worked wonders on my bike. if that doesn't do anything then i'd clean the carbs.

Assuming you are opening the throttle with a smooth motion, I think hesitation suggests dirty carbs.

However, by drilling out the exhaust you have increased air flow and likely leaned out the fuel mixture. It is possible that this would require rejetting. I suggest searching the forum (or the wiki?) to find out what jetting others have used with a drilled exhaust. Alternately, I'm sure others will chime in soon with jetting ideas.

p.s. I live in B.C. too! (Vancouver). Whereabouts are you?

BUMP.

ANYONE HAVE ANY LUCK USING SEAFOAM? IS IT WORTH IT?

Seafoam can clear out all the crap from the tank, shoot it into the carbs and destroy them (definetly need cleaning then).
I'd clean tank and carbs, its cheap enough to be free IMHO. Just elbow grease. You dont expect a ridiculously cheap bike to be free of these little bits of work here and there do you. Heck I expect even the high $$ ones to need it.
Cool.

Buddha,

Is he OK to use stock jetting (Canadian) with a drilled exhaust?

I had a dead spot on take off like that on my old GSXR-750, turned out to be a cracked coil. Go figure.. And what do you know it was the last thing I checked.

Canadian 95's came jetted better than ours. I'd leave it be till you get into the carbs
Cool.
