Looking at some new cables. Clutch cable is cracked and needs to be replaced for sure. Throttle, I'd just be picking up a spare.
Both cables are pretty pricey, especially clutch cables at $60 or so, maybe a little less with some digging. Motobins has some for the 75c that are quite cheap (£20, so about about $38 CAD right now, plus I wouldn't be paying sales tax), but none of the regular ones. The only ones they have for a pre-6/86 K75c (mine's a 4/86) they're listed as "featherlight". If you've never heard of this, search Motobins for their part # 35250F
Anyone have any experience with these? Are they any good?
