Hi, need a little advise...I decided to chain my chaincase oil and have it apart and the mess cleaned up. I'm ready to reassemble the chaincase cover to the fixed part. My question is: What do I do with the shifting fork? Does is just sit in the down position as I tighten the bolts? Any other tips or info on this job would be appreciated. I done it before with my sons 580, but it doesn't have reverse.
