My cousin was doing a new top-end on his 2008 M8 and got coolant in his crankcase... is there a drain? I can't find one in any parts diagrams. If not, is there any way to get the coolant out without taking the crankcase apart?

Thanks.

Suck it up with towels and swish it out with some premix. You don't have to split the case but you do need the jugs off.

Just take a shop rag that is brand new and clean and run a few of them through the crank cases and it will mop up the coolant. The pour some 2 stroke oil in the bearing/rod area and turn the motor over slowly a couple times before putting the top end back and and you should be just fine.

I had the same thing happen rebuilding the top end of my '05 M7. Just stuck a few clean shop rags down there and it was clean as could be. Put some oil in her, buttoned her back up and she ran like a top!

Second on the shop vac. Duct tape a 1/4" fuel line on the end. Wash it out with brake clean and suck it clean. Put some injection oil in a oil can and pump some in the bearings.
