Hi stigger, regarding the clutch plates, i havent done this myself, it was advised by my mech. Here, somewhere in 2006-2007, they have a 1 make race for the hyo, and all of the gt's were tricked out. He was involved int he race bike developments as well. Now, the thing I noticed form what he listed, the reason their 05's race bikes were reliable even when thrashed is, they have changed the valves, all with performance single piece valves, obviously the electrical were simplified as they have no needs for headlights, brake lights etc, front and rear shocks were re-worked, and other stuff to improve the handling. I am going to do the clutch plates once mine is worn out, thats going to be a while.
The sticky regarding charging system here is a must read. I think for efi model, charging issue will be more pronounced as they need to have a stable electrical system. It is better to recoil the stator with thicker wires as the OEM tend to burn, especially if you live in the 9-10K RPM most of the time. Not to back Hyo or whatsoever, in my experience with motorcycle, not one is free from electrical gremlins, I've seen an 08 ZX10 burn its rec/reg 1 week fresh out of the showroom, in 3 months, since November 2010, i've helped a few friends, all with electrical issue, an R1, a virago 250, a KSR110 .. Problem with bike is, the charging sytem itself, u need to have adequate charge at low revs, yet need to limit it at higher revs to prevent meltdown, cars have better luck with electrical, though i do agree, Hyo just haven't perfected their electrical yet. Something you need to DIY.
