    Opening up the d plate?

    I have a group k 1390 gpr and was told to open up the d plate by a few people. I was told open it up to where the middle of the D to the flat side of the D messures 2 5/16 inches. Sound good?

    Thanks

    I think I found what threw me off. I did not realize that the Riva was a little larger than the R&D. I am going to open it up from 2 3/16 to 2 5/16. Thanks again!

    I opened my Riva up .100" also, just on the flat part. I really couldnt tell if there was a gain or not but It sure didnt hurt anything.
