there are a couple of members on here who did a yz250 swap, i think someone did either a yz125 or ktm 125 swap, and someone did a yz85 swap i'm fairly sure.

yepo tjsdaname put a 90cc stroked yz85 engine into a blasty for the mod90 class !
wit regards to the 125 swap it would be more tuneable then a blaster engine and more powerful but it might not b a torquey as long as the frame was build around the pipe and not the pipe round the frame it should go lyk a raped ape
