Fist mod to pop out is the new color.
I was fortunate enough to find a brand new original black tank. Some might ask: Why change it? The reason is that although I think the red is nice, the black tank seems smaller (optical illusion). I also think that the logo location is better in this tank model. And lastly: I just like black for the GT1000.
Second obvious mod is the exhaust.
Another forum member sold me a Marving Slip-on set (Thanks Roadie). I polished it and placed it along with a nice set of Corse Dynamics Velocity Stacks and an ECU reflash.
