Well, your not former champions - you can't un-become a champion if you know what I mean, just not the current champion
I understand exactly what you mean, I will try the 7's and 8's, just not as of yet since I'm pretty much waiting for my Picco to kill itself.
Once I get the RB re-pinched or get a new sleeve (most likely a new sleeve) Ill break it in with the 6 and try from there. Just saying that because the engine probably only reaches around 30K max, it never needed the extra cooling and still had twice as much power when it hit the sweet spot than the rest - it was like I hit the "jet mode" button XD XD
All help is appreciated, don't think Im not taking it aboard. Not every track I go to is as large as my home track, if you can call it a track XD
