cylinder swap

[christopher21]

Hello all! Well I took my newly running 83' 250r to the badlands here in indiana. On my second day of actually riding it I blew it up. It was bored .80 over so boring is not an option. If I have to I want to get it resleeved. However, If I come across a good one on ebay I will buy it. MY question however is:
WHAT YEAR AND MODELS WILL BOLT ONTO MY MOTOR WITH LITTLE OR NO MODIFICATIONS.

THANK YOU EVERYONE THAT HELPED ME IN THE PAST
IT IS NICE TO KNOW PEOPLE TAKE THE TIME TO HELP OTHERS

IF THIS THING EVER RUNS AGAIN MAYBE I'LL SEE YOU AROUND:headbang: :headbang: :headbang:

81 THROUGH 84 WILL BOLT RIGHT ON!!! BUT REMEMBER THEY INCREASED PERFORMANCE WITH EVERY MODEL YEAR BY A LITTLE TOO SO LOOK FOR A 84 ,,,, THERE ARE LOTSA THEM ON EBAY TOO,,,,,,,,,

did honda make a 81-84 dirt bike or four wheeler 250r?
if they did would it work still?

they didnt start making 250r quads til 86 and they were water cooled ,but the 250r engine is base on the cr 250r bike engine and i think the heads will interchange thruough the same yrs
