Well, you're unlikely to have the same problems that I did... you're out of warranty. Also, if it fails you can follow up with the owner for 3 months rather than KTM. I think that, from memory, the sprocket seal tends to fail and the CDI can cause problems. I'm not sure whether they've got the same water pump seal issue as all V twin KTMs but I'd be surprised if they used a different part/design for the singles as the twins.
Good luck.
