four stroke engine mount question.

So...

I know a few folks dont like the demon engines with their hoot gearbox, i am going to swap the chain with the down home american made chain soon. but for some reason i dont know if i should have the mounting plate at a exact horizontal mount with the ground or if i can get away with slightly leaning more forward in order to have enough clearance for my air-box. Will this effect or alter the angel with the chain? or can i get away with this?

new engine running.

i realized this... after i upgrade to a cvt ill be fabricating a metal fairing over the engine/ possibly copper. and figure a way for electric starting/kick bar like real bikes!
