    1980 GSX750E Racer project

    Bought this a couple of years ago, and have been riding/upgrading it along the way. Currently it's parked in my fathers garage, next to my brothers GSX750 and my fathers Dnepr.

    This is how I bought it:


    This is before being parked in the garage:



    What has been done?
    *Valve adjustment
    *Compression test
    *Changed fuel line
    *Mounted new headlight and handlebars
    *Powder coated some chrome parts black
    *Sandblasted and painted seat pan and some other stuff

    Carbs were done by previous owner just before I bought it.

    What am I currently doing?
    *Changing dash to Danmoto Micro
    *Changing to stainless steel brake lines
    *Refurbing all brake calipers + new pads
    *Mounting Delkevic 4-1 exhaust
    *Looking for new rear shocks


    I have one stock seat in good condition and an extra that I plan to have somebody retrim.

    These are the brake calipers, do they have to be changed?



    And this is the current state of the bike, with newly home-powder coated parts and Delkevic exhaust (just test-fitted):



    This is a bit of a random status update of the bike as it sits now, I will try to update when I do something to it. My father lives 3 hours away, so don't expect updates every week :P

    I ordered some RFY-shocks, but after seeing the fit of the clevis I sold them. Currently I'm thinking YSS-shocks. Read somewhere on the forum that I should go for 330mm-340mm?

    Yes, change those caliper pistons and get new OEM seals. The pitting will wear away your new seals prematurely. It's from water getting into the brake fluid.

      Plus one on changing your caliper pistons. Best replaced with stainless steel aftermarket versions and it's job done forever.

          Try Nick Chambers via eBay:



          He'll be cheapest by some margin or Wemoto list them.

                  I was very pleased with the look, so hope you will be happy with it too!

                  I'll try to make some progress soon, I have some parts to overhaul before going to the garage next time I'll post pictures soon

                      Hi. Had some RFY shocks that I planned to put on the bike, but the clevis mount did not fit at all. So I'm thinking about these YSS shocks, only difference is amount of adjustability, right? Any other good YSS dealers in Europe?

                            I will follow this! Im very curious of which shocks you go with. I have been looking around also. First thought of the TEC's with adjustable ride height but heard the quality isnt really good. Thats a pretty exhaust pipe too!

                              Thanks for reminding me to update!

                              I bought YSS suspension:



                              Expensive, but hopefully worth every penny


                              Alot of things happening at the moment, so very little time to work on the bike this spring
