yea haha i guess these types of builds have died off considering the lack of resources or machine shops being able to do what is requested. when i was talking to kenny roberts he was mentioning how when he had an air fooler back in the day that had a 300 kit on it he did a mod on it where he re sleeved that 300 cylinder made to accept a yz400 piston which comes out to a 85mm bore. he said it worked but never ran right but that was just because he never had a good enough pipe to go along with the build, this was also before he even got into the pipe business himself or else he easily could've made one himself. i was almost going to this route on my build but we all know how hard it is to even find the 300 cylinders and heads now n days. since the fl350 cylinder and head were way easier to find i just went ahead with going this route. i did come across a guy that has 2 sets of 300 cylinders and heads but he said they were already claimed 2 other guys which wasn't surprising.
