Topic: Engine/frame angle

[babyfood1217]

I know there's a thread around here that this topic was briefly addressed, but nothing shows up.  Perhaps bringing it up will refresh my memory of where it is...

Does the engine in my cb750 has to be at the angle it is at?  I'm curious about rotating it forward slightly (don't ask...seriously), and all said and done, I would essentially be bolting it with stock bolts to the stock frame at the stock engine mount points, and instead be affecting its' angle with suspension modifications.  I figured that an intake track needs to be as straight as possible, and engine mass and center of gravity is a big things, but aside from that, what affect would an angle change have on the performance of the ENGINE (don't worry about the mass/CoG/suspension)

I'd be concerned with the gearbox gettin sufficient lubrication if the whole engine is canted forward.  also I'd be worried about oil pooling up in the head at the front of your valve cover.   

Other than that, have fun and let us know what happens.

If you're always doing a wheelie there won't be any problem.

Aren't the oil return passages located at the front of the head? 
Personally I'd have a look at some pictures of Seely, Rickman and Egli framed CB750's for some guidance as I seem to remember noticing that (one or some of) those had engine positions that looked to be angled greater than stock. 
I don't know that I'd worry about oil pressure to the transmission much, as long as your pump screen is clean and you get good pressure from your pump.
