So, popped the primary clutch spring on my T-Pro. I'm running a MTNTK turbo at about 8lbs of boost. I took it into the boys at CW Foothills, and they found it was broke, which I'm grateful for. I didn't even know, it just seemed to engage "early". Anyway, I've never broke one of these things. My question is: Is this a common issue? Should a guy have one on hand as a spare? 12 years of sledding and I've never had one break.
