Comparability between GS models

[Ska3454]

Hi Everyone,

I recently purchased a project bike, which is a 1982 GS650G and I am fairly new at working on it. I continue to find parts of the GS650E, specifically airboxes, tanks, etc. and was wondering if anyone knew if these were compatible across models? Also, if there is a good resource to check into compatibility. Thanks for your help!

Compatability is very tricky. especially seats, tanks, body parts in general BUT your first look might be the parts fiches a la CMNSL or several others that other members prefer. Specifically, CMNSL has a list of bikes the part will fit and this sometimes includes a modern substitute.

You can take the part number elsewhere online and get better pictures and maybe a better communication with a seller as to exact particulars.

Thanks, Gorminrider! Had a quick look through the website and there seems to be a lot of great resources. I finally had a chance to compare fiches between the 650E and 650G airboxes and it helped make sense of the ones I've found online. Still on the hunt for a 650G airbox. Much appreciated!

Here's the "acid test" Find a website that sells genuine Suzuki parts and look up the parts fische for your bike. You can compare part numbers between different models to check for compatibility.

Thanks, Lab3. Just to confirm what you're saying - if while comparing fisches and part numbers between different bike models, I notice the part numbers match up, then I know they are cross-compatible?

You are correct

[LAB3]

Yep, that's how it works! I'm pretty sure it works with other Suzuki products as well. If you cross reference the o-ring that seals the dip stick on my bike it cross references to a fuel seal on a Suzuki outboard. Just for grins I checked it out, sure enough, same o-ring.

ServiceHonda.com is a good site too. It’ll show you every application of a part number in a single list.

The 650G is a great bike, but you should know that it's a bit of an oddball. Most of the four-cylinder GSes (including the 650E) have roller-bearing cranks, the 650G has plain bearings. It uses smaller spark plugs. It uses different chrome covers on the ends of the cylinder head. The cams have sprockets with a different number of teeth than the 650E, so be careful.

Just a bunch of little details like that, so be sure to keep your eyes open.

Did I mention that it's a great bike?

Much appreciated insight, guys. Thanks again!

Anyone know if an exhaust from 650e fit on a 650l?

I don't know for certain that it will not work on a 650 G or L, but the head pipe part numbers for the plain bearing G and L are different than the chain drive, roller bearing crank E. Also, the 650E, in addition to having a different intake cam lift or timing, is said to have larger bore exhaust. Not sure if that includes bigger exhaust ports in the head, but I seriously doubt it. I'm thinking that the E exhaust will not fit. The E was rated at about 6 hp more than the G/L. Probably even more difference at the rear wheel with chain vs. shaft.

Like Steve said, a number of differences between the fairly rare 650e and the shaft drive 650's. There seems to be more 650L's being broken down with parts for sale on places like ebay, most of the time. Out of the 4 GS650 models, the L is likely the easiest to get used exhaust and body parts for much of the time. Good luck with the project and hope you have a riding bike soon, if it's not already.

I never had a clue chain drive 650's had roller bearing crank & shaft drives had plain bearings. I really couldn't (didn't) believe it till I looked it up on the parts fische. That just amazes the heck out of me. Great info. around here.
