My old build thread starting back in 2006 is here, but now that the GSR has a Projects/Rebuilds section, thought I'd start up a new thread to share current progress on this build.
Mods include:
Engine/air/fuel/electrical
Wiseco 1100 cc overbore piston kit
Web Cam .395 lift camshafts
GRC welded clutch basket w/ APE hardened clutch hub nut
Oil pump with uprated oil pump gears for higher flow
Dyna coils/spark plug leads
Mikuni RS flatslide carbs
Pingel fuel tap
1989 GSXR 1100 4-2-1 header modified to bolt up to the GS1000 head
Hindle 4-2-1 full exhaust system
Electrosport stator and R/R
Suspension/brakes/controls
2004 GSXR 1000 front end, resprung to 1.0 kg/mm Racetech springs to account for bike/rider combined weight
Monoshock conversion with 2006 GSXR 1000 swingarm and GSXR 750 rear wheel
520 chain conversion
Goodridge steel braided brake lines
GSXR rearsets
The bike as it sits now after tinkering a bit, with the addition of a Yoshimura slip-on (muffler bracket removed temporarily shown here), Earl's oil cooler and billet oil cooler takeoff, superbike bars, and Koso electronic tach/speedo/oil temperature gauge.
I've changed the rear wheel to a 2006 GSXR 750 for better chain alignment. More on that later...
Tail section is off until I get the bodywork repainted.
In order to improve aesthetics (hunched over stance due to short GSXR 1000 forks) and handling (a bit more twitchy/unstable when leaned over than I'd like so more rake & trail needed), I plan on adding about 20 mm of front ride height via some fork cap extensions for the GSXR forks.
As it so happens, the board on the ground under the front wheel is about 20 mm high so it gives a good preview of the before and after stance.

Other plans for the cold weather wrenching season include:
- Adding a heavier spring for the rear shock to match the bike & rider's weight better - currently too soft
- Fixing the leaky oil pan
- Getting the chain run perfect. I've mocked up a 2006 GSXR 750 rear wheel in the pics above to help in the effort to get the chain run straight. I was using a 2005 GSXR 750 rear wheel before and had to machine the sprocket carrier and cut down the cush drive rubbers to get the chain in the ballpark of alignment. The 06 750 rear wheel is narrower than the 05 at the hub & sprocket by about 5-6 mm without modification. Once I shim the 5/8" offset front sprocket, I hope that the chain alignment will be perfect.
- Adding a wideband oxygen sensor & gauge (Dynojet Wideband 2) to truly dial in the RS flatslide carburetors
- Paint and bodywork - needs a respray and the dent pulled out of the left side of the tank () after a 0 MPH tipover. Case covers need to be either resprayed or powdercoated. Currently leaning toward a GS1000S style paintjob but in darker, solid blue on top of the tank & tail.
Paint will be somewhere along these lines:
Stay tuned...
