Harley owners, I need a bit of help figuring out your transmissions.
I've been eyeballing a Rotax 503 for a swap on my bike and because they don't have a regular transmission, I was thinking "don't harleys use an external belt driven tranny".
I did a quick check on ebay for them and noticed that a lot of them had some sort of cooling or oil hoses going to the tranny, do they require an external oil pump of some sort? I thought they'd be splash lubricated like a regular transmission is.
