hey adam this sites pretty good for not being full of idiots ripping on anyone with any idea beyond riding something bigger than (read other than) an ahem (cough cough spit) honda 250f
cyphers got some good ideas about frames. hes not having a go at you
I can see where the "why" question could be taken the wrong way and that kind of typical response is well based on thumpertalk.com :twisted:
I think you would have some issues getting the air intake on the new engine to line up with a workable location for an air filter and possibly the swingarm mount might mean that you'd have to cut the lower cradle and change it.
my "new" frame looks like the Llamberger, nothing left but the lower cradle, pics soon
