What is the best engine to go with? Preferably best while still cheaper ( i know the newest 450 is prob the best) But im looking for resonably priced. I seen alot of the hybrid yzf426 400ex's. How are they? Is it worth the swap? What all needs to be done? I know the front mounts need to be changed but thats no big deal to me. I have a full machine shop with everything. The main thing is how does it match to the swing arm area??
