What's up, I will be in Ft. Myers, and look forward to meeting you. I think I will run the RR, but I'm still undecided because my Sirio was extremely fast down there for the warmup race two weekends ago, but there is the reliability issue with their rods. I think the RR may be perfect on that track.
That's seemed to me... will try some things.... one will be a metamorphosed RR12 who changed the powerband trying to find brutal mid and high rpms losing some of the low-end that has.
and the other will be a NS12 or RS12 with a very close gearing. The RS12 loves to whine a lot.
What kind of gearing tried you tried on the MTX3 (if you still use it) in the warm-up race... planning to carry 20/25, 20/26 and 21/27 for pinions on 0.8 gearing. Probably the 20/25 will be a little short, but need to try it. 20/26 with 58/53 is mine stock gearing for mine local track, a little longer than Ft. Myers (900Ft long with some ample turns and two hairpins).
One thing that scares me the sh*t what is the stinger size on the exhausts is the maximum under ROAR rules? 5 or 5.2mm? All mine pipes go at 5.1... and need to know if need new pipes.
