Couple things here and there, an ignition side case cover and a stock bore piston if you have one that isn't junk. People want an arm and a leg for those covers on fleabay.
if anyone has a CT90 or CT110 laying around, I noticed they have OEM 17s and it looks like an easy swap onto an XR but I havnt had the parts to try it. BTW the ignitions were updated from mechanical points in '92 but Ive been able to get more advance and curve adjustments out of the points type than the CDIs. '85 is the first year for the pro-link suspension.
I've got both, the kickstarter is primered since it had some rust, i don't know if that matters to you not.
