I believe they are all pretty much the same as far as the ends for the cable. If not,,,, than i know there are a bunch of different threaded ends to make just about any cable work with any throttle. Realy the only concern i could see is that you would just need to make sure the thumb throttle will open the carb enough. I wouldnt think that would be a problem with a yfz thumb throttle opening a 26mm blaster carb but it could be an issue the other way around. Like stated previously the Banshee thumb throttle is the same. (it is opening the same exact saize carb only 2 of them)....
Also i do remember when i sold just the actual lever and it was the same part # as just about every yamaha atv out there.
