    iChambers GS750L Project build

    Hey Everybody, I'm glad to have come across this forum since recently buying my 1979 GS750L. I find forums to be one of the best sources for collective knowledge on a any specific subject. I hope to glean what I can from the members here and hopefully contribute some knowledge or creativity here as well.

    To introduce myself a bit, I am a product designer and recently started working in the motorcycle industry but mostly with Harley aftermarket parts. I design new accessories and help give guidance to evolving products as well.

    Ok so on to the bike and build. The bike as previously stated is a 1979 GS750L and had mid 20,000 miles on it when I bought it, or at least that is what the stock speedo reads. It was kept in pretty good stock condition. Here is the picture as it was when i bought it.

    I am not a super fan of the big sissy bar attempt a a cruiser chopper that suzuki made on this bike. I will be building this bike to be a more sporty but practical build, as i will be using it for occasional work transportation and to ride to local shows and occasionally on weekends for fun.

    First this was to get a better par of bars that didn't make me feel as much like a parachute. I also removed the sissy bar. Performance wise I have installed a pair of Progressive suspension 412 shocks with 13"springs to keep the stock height and reinvigorate the rear suspension.

    I am a bit on the vertically challanged side at 5' 5" and wanted a lower seat height. Rather than do any major chopping I found that a early sportster seat fits up to the 750L frame nicely. I got a Burly Brand Brat seat 2 up version. The only modification required was to grind of the front stock seat mounting hook, fab a quick tab for the seat to hook into and drill o single hole in the rear fender for a bolt to mount the seat.


    Because the rear fender is split at the peak with the plastic inner fender the plastic was now exposed. I wanted to shorten up the rear a bit anyway so I experimented with relocating the stock fender. I was basically able to move it forward using the stock locating pins from the inner fender with the fenders rear monting hols and drilled new monting holes at the rear strut location in the fender moving it forward a good 8-10 inches almost entirely filling the exposed plastic area with the metal fender. I trimmed the inner fender with some tin snips so it would still be able to be used and overlap the metal fender properly.


    but with a thinner seat now a void is open under the tank

    I found an empty computer housing some one had put on the curb that had some cool metal panels with louvers. I was able to cut it with tin snips and shape it to sit in the void and clean it up a bit with some style. When I repaint the tank I will fix up that nasty edge a bit.



    Here is how it sits now.


    This is my rough plan for moving forward with the build.


    I will be making some practical mods like custom bag and I will be replacing lighting with sleeker brighter options. I will most likely lower the front suspensions couple inches when I replace the fork springs and rebuild the old spungy forks. <br> <br> Beyond cosmetics, The carbs need syncing and tuning a bit. The PO rebuilt them but didnt have a tool to properly sync them. But the bike is running decently after a little air screw adjustments. There is a leak in the valve cover gasket and I have the replacement part and the repair on my to do list. I hope some of you like the build and I welcome feedback. I'm sure I will be asking for help at some point in the build / life of this bike.

    I realized this might be in the wrong section of the forum. I was hoping to kinda track the general build of my bike which is mostly cosmetic with a few mechanical repairs. If an admin would like to move the thread, i think it woul be better suited in the appearance section.

      I think it fairly qualifies as a Project if not a full out Rebuild. I like the idea of that seat and appreciate that you did at least make the effort to address the tank to seat gap.

        Thanks Shadowfocus603, Ya the gap doesn't look too bad but I do want to do something to clean it up. I haven't completely decided how to mount the plate I made, or if I want to fabricate something that actually fits up in there better.

        Today I replaced the valve cover gasket. The previous one had stared leaking oil and clearly needed replacement. The repair went fairly smoothly and after I took it for a 30-40 min ride to a local nearby canyon and it all seemed to be running well. I bought a can of engine degreaser to hopefully clean up the oil and dirt the engine has accumulated.

        I sorta got an issue with my lighting figured out after replacing the old flasher with a new one that will be friendly to all my future LED lighting and wiring thing back correctly, But I still haven't figured out why the turn signals will not work when the headlight is on. It has been like that since I got it and still has the issue after replacing the flasher. Not sure if the PO messed with wiring much it didn't really look like it when I was going through the rear wiring. Anybody got any ideas about the headlight issue?

          Ok well I replaced the valve cover gasket successfully, but the bike needed a lot more attention than i had time to give it before riding it much so the bike is in the shop getting carbs synced and tuned properly, new spark plugs, oil change, new chain and sprockets, and they had to send the tank out to be repaired because the petcock was weeping gasoline due to a stripped thread for one of the bolts. I am glad that after all this the bike will be ready to safely ride and i can continue my modifications at my own pace while still riding.

          Here is a sketch I did of what I think I am gonna do with the paint for the tank.

          Anyone know of a good alternative for the crash bars? I found that my left side crash bar has a broken mount and probably wouldn't do much good if it went down. Anybody put plastic sliders like on a sportbike or something?

            Well I got the bike back on friday and it is running great. I also had received my tail light stuff while it was in the shop, so as soon as it was back i fabricated a new bracket to hold the tail lights and license plate. I had also previous installed the new turn signals.


            I also changed my direction on the paint to a different graphic, still simple but with more aggressive flow to it.

                Here is another quick pick of the paint. You can see the graphic a bit better in this one.
