Well the original DT's from the 70s and early 80s were air cooled as well.. If somebody who has tried the Blaster 200 - IT 200 parts swap could confirm this, I will go and get a blaster cylinder for this engine.
Hey guys, I tried searching but couldn't come up with the exact info I'm looking for..
I'm restoring a bike for a friend, it's a 1986 IT 200.. The engine has some extensive damage, I've been working on bikes for 25 years and this is probably the worst butcher job I've seen in an engine...
