If it is an mpi turbo you should still be under warranty....
Mine is, only problem is by the time they come up with a fix it won't be any more. Rode another 40 miles yesterday, boondocking and climbing and lost another half quart. I never rolled the sled, just carving left and right. I love the sled and turbo, the thing handles amazing and the power is great. Just getting tired of cleaning up oil after every ride.
Big Fish, if you block the return line how would the oil that ends up in the breather box get back to the tank?
