do a search and there is a guy who put a kx80 engine in a 300ex, im sure he could help you

yeah i did this with a cr80 engine and it has lots of power but im not sure if it has more. The radiator you can put in the front where part of the frame comes straight down. its not the easiest thing in the world to do though.

[roostin_dale]

can you post some pics of that?

holy crap.... how big is that back sprocket.... and when u mounted the motor did it bolt up to the stock motor mounts?

[honda_racer_713]

alright we no longer have that back sprocket on because we have a different motor in it now but its a 50 tooth. and we had to make motor mounts but the motor mounts bolted onto the stock motor mounts........if that makes any sense at all

wat kyle is trying to say is.... they made extendd peices of metal.. bolted them to the stock 300 motor mounts.. then the other end to the bike motor... so the mount is extended.... i think thats a better explination....
