Looks good! Nicer price too.
Just my gut feel, but 45 degrees seems like a lot for a wet sump engine. Already it has to deal with road grades and g-forces (which can essentially alter the normal "level") and avoid oil starvation where you start sucking air. I don't think you're concerned so much with the oil filter placement as the oil screen and oil pan, below. The oil screen needs to always suck oil, but at the same time, the crankshaft can't splash "too much" or you blow seals and froth (which is why you can't just overfill to submerge the screen) -- it's a balancing act. You probably want your drain plug near a low point as well (along with the oil screen).I have the engine orientation about 45deg off of normal axis
Not exactly. Side-to-side maybe but not fore and aft. I regularly record accelerations of 1g and braking of 3g. 1g is equal to 45 degrees. Not sure about 3g.PS one other thing to keep in mind, as a go-kart, the engine will experience sideways g-forces in the oil pan that don't exist on a motorcycle (motorcycle g-forces are always "down" when riding, even when turning!) -- ..........
The go-kart, going around a simple a horizontal circular track, will likely experience 1G sideways (before slip), in addition to 1G down -- which would pull the oil to a 45 degree plane against the outside/bottom of the sump. That can be sustained indefinitely, unlike braking and accelerating g-forces which are by definition transient.Not exactly. Side-to-side maybe but not fore and aft.

Nice.And..... I’m pretty sure the sump is separated from the crank. Looking from the clutch side there appears to just be a big hole for the oil return.
