I love the heated grips on mine! I put Bike master heated grips on, rode twice with them on high and have to turn it down to about half to be comfortable. You'll probably have to grid the flanges off the throttle tube in order to fit them on.
Rebuilt front forks with Racetech Emulators and new springs.
Replaced rear shock with GSXR 750, and replaced exhaust with new IXIL.
Also replaced Dunlops with Michelin PR4's.
Now it handles like it's on rails.... (Put the removed Dunlops on my 2014 Honda CTX700 DCT ABS).
Also removed EVAP canister and routed extension vent hose out the back. (I'm in California, so the gas cap is NOT ventilated).
Might get Hepco & Becker C-Bow mounts. (Already have the soft side bags from my Aprilia Mana 850 GT.)
Cleaned up some wiring and dropped her back off at the dealer to inspect the charging system. was just in a for a rectifier/regulator replacement for recall, they said the system was charging and working but isnt and are going to try and have suzuki pay for a replacement since they verified it was working when i left and gave out. Some how i dont think suzuki will cover a Generator/Stator replacement.
