Finally broke 70!!!
added an XS I/C on friday and took the RXT out yesterday, it was running like crap, would only hit 6000 rpms, so i put it back on the trailer and checked everything, looked o.k... put it back on the water and still only getting up to 6000 rpms, rode it for about 5 minutes and it finally cleared up and shot up to 8060...found some flat water and turned on the gps....71.0 and 8040 rpms...whoohoo...and on a hot day..previous best was 68.7 and 8100 rpms.
temp was 100* with high humidity
still need to fill in the rideplate bolt holes..
Im guessing the low rpms are due to how hot it was...
still have not gotton the 42# injectors or a different SC wheel...
cant wait for it to get cool around here to see what it can do...

I'm still looking to break that magic 70mph mark.
Yesterday the best I could get before the GPS batteries died was 67.2 (7950rpms)
1/2 tank, 200lb rider
Outside temp - 93F at 500ft 28% humidity.
This yielded a 3000ft density altitude as seen by the engine.
I guess I need to get an I/C and larger injectors.
That or I just have to wait for it to cool off a bit and then I should break 70.

NEXT GOAL IS 75!!!.....I will need alot more than an x-charger and a rrfpr, I think...
The bogging/missing cleared up on its own, Im guessing with the cooler air from the I/C that the ecu had
to relearn the fuel curve..
also i think the prop is holding me back now, its a 14/17r with 2mm added to it...
I think i screwed it up because i kinked one of the blades...
I was at 68 at 8150 with the 14/17r then i added 4" rear intake, Jims rideplate with skeggs, GH waterbox, XS I/C, and added 2mm to the pitch and now im at 71 at 8050, but is was alot hotter than earlier in the year...also i was getting some bouncing over 70 on flat water, need to shim the plate..

Oh boy......I remember when I first hit 70+....Get ready to shell out some green ones!....Enjoy!...My suggestion...Rude charger, riva ecu, 50# injectors VTS system and a 15/20 prop....75+ easily....nasty acceleration!
