If you live in PA I would say heat won't be a huge issue so I would go with the air since it is 100 bucks cheaper. Additionally if you want a high compression head it would be cheaper with an air...I believe.

also right now there are way better cylinders available for the air cooled motors than the water cooled.

when I place our 1st order I asked Lou for his advise on this subject..
Air cooled has way more performance upgrades as of now, was his answer.. Exactly what I had been thinking!
I trust Lou and order the aircooled!

The air cooled is faster in stock form due to the performance of the head, but that will be addressed in the near future.
or
just get some head work done and you will have a high performance water cooled quad. Wouldn't that be done for any type of racing anyways?
Not really an expensive thing to do, so I wouldn't shy away from the water cooled versions in the 90cc quads in warmer areas.
We even have 44" wide water cooled DRX50s arriving next week, along with a bunch of water cooled 90s.....
I will try to post some feedback once they can be run side by side.
That should be an interesting thing to test out
But yes, Lou is the best!! I call him Yoda, since he seems to know the answer for most things....

the head design is not really the bad part. it is the cylinder and the placing of the transfer ports. the air cooled cylinders are better in this area which means you can do much more in porting one. not saying things cant be done to the water cooled cylinders just as of right now you can get more out of porting with a air cooled cylinder.

Buy a drx 70 water cooled. remove cyl. and throw in trash. goto cycleimports.com and buy a METRAKIT cyl. Install cyl and tell your kid to hold on! These cyl have wicked power out of the box. with a little case modification you will get even more. Just my opinion. I have one and there totally reliable. I will never swith to air cooled.
