Dropped off the bike with the builder and starting the build process. Not able to go as wild as I was hoping (was hoping for a 200+ RWHP), but should bring the bike up to maybe just bit faster than I have ridden. Coming from a legit 160 rwhp GSXR to what I am betting is about 130 RWHP bike was just to much drop for me. Hoping to get this bike up to 170 RWHP on pump gas.
So the build:
Replace the CAMs (looking at some GSXR K5-K6 adjustable cams or possibly the ones from PTR in Austraila)
Replacing the valves and springs to handle more power
Mill the head and thinner head gasket to bring compression up (still leaving it safe for 93 pump gas) Current GSXS 12.5:1 GSXR 2005 which our motor came from 12:9:1. Probably shooting for just over 13.5:1
Port and Polish the heads.
Re-spring forks and massage the valving
Re-spring the shock and tweak the stock valving
ECU Flash to remove the Secondary butterfly restrictions, Timing, engine brake, and still looking at what else can be done. (already remove PAIR and Exhaust valve)
Already done
M4 full exhaust
PAIR mod
Bazzaz TC unit for fuel map customizing (used the auto Tune to update the bike from stock after the exhaust)
Installed but haven't tested Brembo front RC 19 master cylinder (Stock unit was crap 3/4" of lever travel before pressure is applied to the pads)
Installed but haven't tested Spiegler Front and rear lines. (Spiegler is making a kit for the non ABS from my lines, as I live 40 minutes from their shop)
Installed but haven't ridden yet LSL Drag bar from Spiegler. With my short upper body my arm angle to the bars was pretty much horizontal so I had no forward angle to help absorb throttle changes with my body. Lowering the bars a couple inches will make it much better for me. And looking at the competitors sure seemed their bars were already at that level I want.
Hopefully will get a baseline dyno run, but not sure if the builder will get access to a dyno before he starts the tear down.
Will update this thread as I get more information on details of the motor work.
