Gs300 fuel jets different sizes

[Rduffy3]

I recently bought a 1985 gs300l and while cleaning carbs I noticed that the fuel jets were different sizes. Just wondering if anyone could give some insight on this. The holes look like they are the same size but they are different. Also if anyone knows where I can find a service manual for this bike it would be greatly appreciated.

According to partsoutlaw website …both stock main jets are 115….hopefully still stock mikuni

head to bassclifts site for service manual for similar sized bike

The original hosting for Basscliff's site is mostly defunct, or close to it, so please update your bookmarks!

We've moved as much of this info as we can to my server. There's an '82 GS300 service manual here, although I have no idea what differences there may be, if any, between the '82 and the OP's '85.

Bwringer….Odd …I still “see” basscliffs site exactly like I did 12 years ago when I stumbled across it….and bookmarked it.

Yeah, it's gone in and out of existence over the years. It's sitting on the free hosting associated with an ISP Cliff used many years ago, and the resources are scattered over several different scraps of free hosting Cliff found here and there. Basically, it can (and has) go away at any moment, even if it's working at the moment. Many of the resources on other servers are already gone, and frankly I have no idea how DSLextreme hasn't noticed and deleted the site years ago.


Anyway, when it first went down a few years back, I worked with Cliff to get everything consolidated to my server. I have access to plenty of space and bandwidth. We've kept things more or less updated, removed dead links, etc. The original at DSLextreme has not been maintained.

This is someone throwing a jet in when they lost one... Those are the large and small mikuni jets. The rebuild kits should have the correct jets. Can you use them, sure as long as the size is the same.

Unfocused do u know where I can find a good rebuild kit, I just ordered one but when it came the jets were all different sizes and didn’t fit into the carb
