New thread Air cooling 2/2/2014 11:47 AM

now here is something ive thought about before and haven't quite figured it out. how come four stroke motors that are air cooled have much smaller fins versus a two stroke which doesn't run as hot.

my 1984 YZ 490. Just plain fast enough to really pull me around the track and my only win came on that a year and a half ago. against two other yz 490s no less. now why I won we wont get into.

me too, a two wheel drive with a 4.2 v6. guess what? it does anything I need it to. I don't understand why people are obsessed with putting the tailgate up. put a20 dollar rubber mat in the box and nothing will come out.

four stroke owners would say there is an uncompetitive advantage and its ridiculous for a smaller motor to compete against larger ones
