Another RPM question
I still am playing with the RPM shifting point on the 2014 RTS. Since June the most GPM I have gotten 35.1 and that was only once. I notice that in 6th gear the RPM's will go passed 3000 at speeds over 65, is that normal for others. My 2011 pretty much stayed at 5000 regardless the speed.
What am I doing wrong?

I'm not sure that you're doing anything wrong. I've noticed a significant drop in MPG when I increase my cruising speed to 75 mph instead of 70.
Also, how many miles are on the Spyder? What kind of gas are you using? Are you using the eco-assist?
I've got about 3K miles on my '14 RT-L, using 93 octane with ethanol and I'm getting about 35-36 mpg. It's increasing every tank... but slowly.

Increases over 3000 rpms do happen at 65+ in 6th gear. Based on what I have seen mentioned on SL this seems to be the norm.
My current mpg hovers at around 40 mpg. My very first tank was 38 mpg. Now 8,200 miles on the odometer.
I do not drive aggressively, and put 90 octane (highest here) in Alaska. If you pick up the speed beyond 55, the does seem to use a bit more gas. The same situation seems to happen with most vehicles.
When not in 6th gear, I keep the operating revs right around that 3,000 rpm "sweet spot." For me, the is then in the power range for climbing hills, or powering up to more speed.

I've yet to hit 40 mpg and to say I'm not an aggressive drive is an understatement.
Do you use the Eco-Assist? I'm beginning to have my doubts about it's function.
Or maybe it's just this South Louisiana heat evaporating my gas.

I have 2300 miles on it and use high octane( 91 in California). I don't use ECO

I'm going to try some non-ethanol gas on my next tank.
Also, I know keeping track of it on every fill up helps me to be more cognizant of driving habits.

I am not sure how the RPM's stay constant regardless of speed. Seems like a violation of the laws of physics.

RPM's are a combination of speed and gear choices.

Exactly! Unless you have infinitely variable gear ratios RPM changes with speed.

MPG
i just picked up my 14 RT LTD last Thursday. only have 225 miles on it. First tank got 37.6 mpg. Filled up at about 260 miles. 80 miles were hwy miles rest was stop and go around town. it should only get better from here.

I was tickled that my very first tank came in at 37, most of that was 2up and over 70. Fuels do matter, we don't oxygenate fuel here or other Californications...which could affect some folks. Of course that's one tank so no clue if that's accurate, may simply have not filled it full.
Our non-eth has jumped quite a bit for some reason, maybe because boating season is ending, so it's .70 gal diff between 91 no eth and 93 eth. Don't know if I'll try no-eth with the 2014.

My 2014 ACE 1330 has been confined to Alaska its first year of operation. Compared to my Rotax 990, I am very happy with the results. Don't know how either would operate on ethanol, etc. Rotax give me average 30 - 31 mpg and ACE give me 40 - 41 average mpg. 1330 compared to 990, I am very pleased.
