Thread: D-Plate mods?
06-17-2007, 05:25 PM #1
So I have seen and heard people talk about opening up the d-plate... Is this worth while? If so any recomendations on opening size? Anything else I should do why the ski is apart for TB and timing key?

Only open it up if you have a 1390 motor, otherwise leave it stock...

I saw some where, it said to open it up but it said nothing about only after 1390 big bore....
But then again maybe none of that info I saw was correct.

On a 1300 motor opening the D plate a small amount made no difference to the peak rpms.
But if you open up the D plate it will raise the mid range HP - but at some point if you open it too much it will also cause a loss in peak HP.
For a single pipe CC race ski we used a completely open D plate.
