Newbie carb stuff

[Anonymous]

My bike had a MAC 4-1 exhaust and Uni pod filters on it when I got it. It runs and starts fine, runs maybe a hair rich by the smell, but seems to top out at around 65 MPH, even as low as 4th gear. The previous owner seems to have had some good GS knowledge, but I'm gonna check the carbs to see if the jetting is stock or if he adjusted for the mods. My question is this: is there a writeup anywhere on the web that's kind of a step-by-step for carb tuning? I've been reading and getting some of the basics, but I'm still shaky on it.

Also, can anyone give a hint as to what my jetting _should_ be? 1982 GS550L, with the above-described exhaust and filter mods.

Finally, what's a good source for a jet kit if I need one? I coldn't find one for my specific bike at Dynajet. Are there DJ kits for other bikes that will work?

Thanks for any help. This may be the greatest "go here if you're into/need to know about a subject" site on the web. I've learned a lot just reading old posts.

Cool, all those sites have good info. Tunrs out my top end problem was due to the carb vent tubes, which were still in place. I read on this site that a bike with pods should have them removed, so I tried it and it did wonders. Had the bike up over 70 last night, and it still had more to give, even in 5th.

Thanks for all the help.
