Not going to throw a used engine into it?
Nope, I decided long ago that if anything major went it was done, I'm not putting any money into it. It actually lasted much longer than I expected and I nearly stripped it down for parts at the end of it's 2-year warranty. In the first 2 years it went through 2 engines (this last one is an 09 model) 4 batteries, 3 stators, 4 reg/rec, 1 fuel sending unit, rear shock, fuel sending unit, CDI and a fuel petcock. I could not go 3 weeks without a failure the last one coming just 1 week before the warranty ended. That was 8 years ago and not a problem since then. It's taken me around the US in some of the worst weather imaginable for a bike and never missed a beat but now it's time is at an end.
After the US trip I rewarded it with a second front disk and GT650 master cylinder giving it some awesome stopping power, it was right after practicing a panic stop from 130 kph today that the engine went south. Tomorrow I will take a peek under the valve covers out of curiosity but I think the problem is deeper than that.
