Hello,

Just got back from the shop

Ran the '09 Tuono R on the dyno.

Bike temp 181 Deg F

All runs with 3% grade on the drum.

All runs are at the wheel, I have flywheel #'s too.

Run1 266534 Map 2 with Remus Ti slip on, baffles in, K&N filter.
72.8 ft.lbs @ 6933 rpm, 121.5 hp @ 9872 rpm.

Run2 266533 Map 2 with Remus Ti slip on, baffles in, K&N filter.
72.3 ft.lbs @ 6525 rpm, 122.8 hp @ 9571 rpm.

Run 3 266533 Map 2 with Remus Ti slip on, NO baffles, K&N filter.
73.4 ft.lbs @ 8238 rpm, 124.4 @ 9573 rpm.

So the final set up will be #3.

The torque curve had two peaks and a dip with the baffles in it peaked at ~ 6600 rpm then dipped and re-peaked at ~ 8200 rpm
When we took the baffles out the dip went away and the second peak was the max.
A/F looks good and curves are nice and smooth and linear.

Good day at the shop.

Now just waiting to get me tank vacuum problem solved.

Air temp outside was 48 F.
Inside shop and dyno room 70 ~ 75 F
A/F ran right at 14.7
On the full throttle run it was a little lean in the beginning, but who putters around at 3000 rpm
in top gear and then wacks it and waits for it to pull all the way to redline ? not me.
The 10% throttle , 20% and 60% runs all had good A/F ~14.5.
I will post the graph's later hen I get a good connection.
