I had a S ported M90 dropped off to me recently. The owner wanted me to look at it and see if it could be improved. To be honest I have never even seen what has been done to a M90 to make it an S port. Couldnt find any thing in the way of pictures. Decided to post pictures of the porting so people can see what has been done to the case. The workman ship is excellent and everything is smoothed and radiused for good flow. I have no plans to change anything to the case as I dont beleive anything I do will improve on the work already done. Just curious how many others have not seen a S port job but hear about them all the time.
