will exhaust from GS450LX work on GS450SX?

[sicnarf442]

I'm restoring an '81 GS450 SX and have an '83 GS450LX for a parts bike. I'd like to swap exhaust systems, but I suspect they are not 100% interchangeable. Specifically, mounting brackets are slightly different. Has anyone attempted this? Known issues? Also, is exhaust flow restriction same for both bikes? I assume carbs are jetted the same for both models, but would like to be sure

Thanks,

I'm not real flash on the '83's, but I believe most major things like the head are still pretty much the same, meaning the headers should line up ok.

Carb/fueling wise I don't expect any differences.

The only catch will be the muffler mounts, and that's something you'll just have to work out... certainly should be doable I would think!

Pete,

Thanks for the info. That's pretty much what I suspected. By the way, I was reading your scrambler thread before I posted the question and I was really impressed, not just with how nicely your bike turned out, but by your perseverance. It put my discouragement over minor setbacks into perspective. The more I work on the GS450 the more I realize what little gems these bikes are.

Thanks for the compliment Francis! And more than happy to help if I can. I've gotten heaps of help from here over the years so I like to give back where I'm able.

Feel free to start a project thread up and share your progress, both the forum at large and myself will be happy to read along
