Thread: Pushing 70!!
09-03-2007, 04:14 PM #1
Finally got some decent test results today. The weather was typical for Florida, 90 degree air; 85 degree water and 70% humidity. Too dang many boaters out today - it was hard to find good water.
Anyway, I've started to work on the wifes Ultra. The last two weeks of testing has been RPMs only - no GPS. Today I gave her the GPS and let her take a couple of runs - the fastest was a 69.7 and 69.8. The RPMs were running right at 7780.
So far, the only "purchased" parts are (less than $200):
R&D PPK and Cool Air Kit
R-Rated Value Cover Block offs
The ski just hit 55 hours. I've done several oil changes, and now am running Mobil 1 synthetic. At first, I had gas in the oil and air intake tube like several others have reported. The blow by problem is getting much better, with almost no gas in the drain tube, and just a hint in the oil. This hasn't been a problem for me anyway, as I would have changed the oil several times either way. When my wife asked me why some many oil changes as compared to her car, I replied that we run the skis basically with an on-off switch. We're either sitting or full bore - not much in between. Hell, I expect some blow-by under these conditions. And no, the bottom ring isn't bowing because of SC pressure (cause if it was we would all be looking for pieces of our blown apart top ring).
My goal this season has been to get my GPR single pipe to 75 and the Ultra to 70. Looks like I need some new goals

Congrats on the numbers Gator - they look good.....

Those are great numbers. Congratulations.... Seems like it costs more money to make a red one go faster than a blue one I guess Harry was right. The blue ones are faster You are right about the R&D filter making the ski louder. I drilled the access cover the filter replaces and you can hear the air sucking in around the handlebars at idle.

Thanks man! I've been following your progress (way to go breaking 70 ) - and now I'm ready to do some more playing with the Ultra. I'm hoping to see the magic seven oh stay steady on the GPS this weekend.
Quick question, how are you liking the BOV block off plate - I'm thinking about ordering one.
It's more fun 'runnin the Ultra than complaining 'bout them...
