ya the frame rail is the main problem. but it should work perfect since its so close to the frame rail i can either clamp it on there or i can use a self tapping screw maybe but i dont want to risk weaking the frame by drilling a small hole in it either? but once i mount it i am going to make a simple modification the the choke lever depending on what type of choke cable i can grab? my buddy has a cycle shop down here and he has lots of old broken down bikes and quads and he's gonna let me look around. and then ill probly just run the cable up between the handle bars and headlight? i think it will work what do u think?
