No that will go some with a dumy tank an ducts will keep those cool enough, theyre up there to get cg lower frames a bit chunky tho and brazed joints.. Some one needs a tig.
Kinda cool but cross overs never really work well, just buy a snowmobile. Did Husky ever dabble with them?
I've ridden them and like it a lot. Theres a good following for them here. Much more fun than a sled for me. Its like the difference between quads and bikes.
