My sled has the MPI tunnel extension and rolled chaincase. Per MPI, the conversion uses the stock chain and case. My question, which may be dumb, is where is the drain bolt for the chaincase? There is a bolt in the tunnel which appears to be in the same location as the stock drain plug, but it clearly does not drain the case. I cannot for the life of me figure out how to get to a drain plug. Pulling the cover seems like a massive pain and mess due to the bellypan. Any advice?
I should add these photos from the old MPI website too. 
if memory serves, in stock location, it is on the inside of the tunnel to the left of the drive axle below it when looking at the cover of the chain case.
might have gunk inside blocking the port.
