    Hello I bought my son a 07 senior adventure and he loves it so much so now he want to race. I am afraid that the bike will over heat. It gets very hot where I live (110) in the summer. I have already bought a pro circuit pipe and am wondering should I get the 19mm or 21mm carb? I also am adding shims to the clutch getting rid of the springs. so my question is can I swap a LC cylinder and head along with water pump and radiator for my air cooled? I have found all these items on ebay at a good prices.

    you will have a problem fitting the radiator, the radiator mount is a welded part of the frame,

    Straight forward answer is yes if you have the parts but not sure if your frame will have radiator mountings.

    You would be better off selling the Adventure and buying a Pro Jr.

    We raced our adventure in 110 temps. The only time it over heated was in the mud when they over watered the track.

    But the performance on the LC's is much more reliable and powerful than the Adventure.

    I'm not sure why they have different part #s , we ran the AC cylinder and head on our LC bottom end and the bike made the same power as it did when it was LC ,
    could be a strength issue maybe? , the SR does spin a lot faster than the MA

    Just sell it and get LC one. Do the math, it just don't add up....
    a Mini and SR adventure is what it is. You WILL be out more money trying to make a Adventure run like a SX than if you just got a SX.

    But on the other hand the SR Adventure we had never over heated and it was piped up and stuff in summertime here in OK, just as hot....
