Yes, there is an early and a late blank, and they are inverse from one another, as Peruano said. My TW's are a mixture of early and late ignition switches, helmet locks and fuel caps. LOL. One bike has 3 keys. If I recall, the stealer gets 13 bucks just for the blanks, and I had to go get them cut elsewhere.
FYI,my local Yamaha counter guy is pretty good, and has always been able to crossreference, scrounge or locate substitutes for things. But yesterday he told me that both Yamaha and the individual dealers have recently embraced the "10 year rule" in a big way, and not to expect him to continue to be a good parts guy, cuz they took all his tools away (parts fiche, service manuals, etc.) concerning anything beyond ten years. Even their service dept. is expected to get all info online from Yamaha, including service manuals. Paperless shop, front to back. The only paper remaining are catalogs for aftermarket parts.
That means that next year things like TK carb parts, drum brake shoes and early key blanks are potentially gunna vaporize?
Xracer, are those Curtis numbers early and late, respectively?
