i assume ur blasty is a pre03 that has cable breaks, i think it would be pretty tough without being able to weld a bracket to hold the master cylinder, other than that it could proabably be done
i have a banshee hydro rear setup.i have a pre 03 to.all you have to do is get the 03+footpegs with the brake and it already has the "extension" on it from the hydros on the 03.the master cylinder you can bolt to where the heel guards bolt to the frame.you will have to make a braket to hold the caliper on unless you get the banshee carrier
i just did a conversion for my yamaha. i have an 02 and the kit i aquired off ebay bolted right up with no welding or drilling what so ever all wwe day was bolt it up adjusted the pads and bled them and they are great. the kit is made by enginete.
