    So I recently destroyed my 2010 KTM 990 adventure engine (at least a cylinder and head) and it was easier to buy a new very low milage 2010 990 Supermoto engine to replace it with. I did a bunch of homework and verified the gearing is the same, the fit is correct, etc.

    Couple of differences I came across and I am wondering if anyone knows why.
    1. The spark plugs are different size/model. Yes I even googled it, the SMT takes a different plug. Why?

    2. The front valve cover on the adventure has 2 oil lines connected to it, the SMT has 1. Again, why? I'm pretty sure I will take the adventure valve cover and put it on the SMT so I don't have to drill holes to customize it.

    You should post this in Orange Crush in the 950/990 section. Several guys have done swaps over there.
