Does anybody know if a crf70 head will bolt onto a 50 engine? I have a 70 carb and head and i know the carb will fit but not sure about the head..? I guess it will as the studs are the same but does anybody know for sure

Thanks

Will fit but will make your engine run like s**t and it will not have as much compression.

tried it on a honda cub and it made performance worse not better

hope this helps

Cheers mate that is actually very helpful, sounds like I will need to run a high compression piston kit to counteract the loss of compression and get the power gains.

thanks :thumbsup:
