Hey all
New here, I got a 94 GS500. Picking it up after work tomorrow. I'll get some pics up soon.
Some quick questions. The bike has been jetted. What exactly does that mean. What does that do for me. And can it be undone.
Also the rear brake squeaks a little. Guy im buying from says its cause he replaced the rear with a stock pad, if I put an aftermarket pad it will stop. I dont believe that. How much can I expect to pay a shop to adjust the rear brakes.
All for now, hope to see you guys on the road.
Anyone in NY?

Hey Zenn. Welcome dude..I've got a 94 also..it's in the posting (She's finished). Jetted sounds like someone rejetted the pilot and main jets.And yes it can be undone..but you may not want to. Depends on how she runs...You have alot of reading to do. :cheers:Just punch in rejetting or jetting matrix into the search bar above.There are volumes of post on the subject,or anyother subject you choose.
Anyway,You'll have fun Ronin

Welcome, zenn!

Ronin already answered the jetting part.

Rear brake squeal is often the result of a wheel in need of alignment. I don't see any reason why stock pads should squeal when aftermarket would not. Regardless, it's not a major problem; you may have to remove the rear pads, grease the pins, and reinstall.

We can help!

My stock pads squealed alittle,  its from the high metallic in the pad,  I would double check the wheel alignment just to make sure.  I replaced my rear pads with EBC ones, no squeel since.  Either way its not a big deal, no damage to the bike will occur.

As far as the jetting, usually new bikes run lean due to emissions standards.  A re-jetting just adds fuel to the motor to eliminate stutters or hard starting.  On older bikes like the 94 he may have jetted it due to and aftermarket exhaust or a high flow filter.  Ask him what it has, or pop the seat and see if it has a k@n or a standard paper.  as long as the bike fires right up, runs good after warmup, and the oil is clean i wouldn't worry to much about the jetting unless you chance something engine wise

Is there an after market exhaust or performance air filter on the bike?That may be the reason behind the rejet.Any exhaust or air filter upgrades require a rejet.If everything is factory the rejet helps with throttle response and warm up times,if done right.If it runs good don't touch it.The GS carbs can be touchy.The rear brake squeal could be wheel out of alinenment,bad pads,or glazed rotor and/or pads.The rear brakes are disc so they're not adjustable.Here are a few links to help anwser your jetting questions.

Thanks everyone.
The thing about undoing the jetting is that I want better fuel econnomy. I think this would burn more gas.

If it's a rejet using the factory exhaust and air filter,your fuel mileage shouldn't change.If it has and after market exhaust and air filter you may loose a little.It all depends on your riding style.

cool.
I think all else (exhaust, filter etc) is stock

Picking the bike up in a few hours, Cant wait.
