I'm working on putting together a really complete writeup of power/torque output of the Yamaha R3 with information and results from testing with a number of different bikes and exhaust systems using the Bazzaz Z-Fi as well as Dynojet PCV with and without ignition timing. I started working on this at the Bazzaz facility, but their dyno reads so much differently than Dynojet dynos everywhere else that I had to redo some of this.

I'm testing at Lee's Cycle in San Diego now, and Gregg Spears has been helping a lot with this also, thanks Gregg! Both have Dynojet dynos that seem to read similiarly and I'm gathering data from a lot of different bikes and setups. My bike did just under 32 HP stock on the Bazzaz dyno, and 36.5 HP on the Lee's Cycle dyno, MUCH more consistent with the Cycleworld test which came in at 36.8 HP, and the baseline numbers Gregg has been getting. Hopefully I can publish the article in January, I want to get back to the track at least once more to test some new stuff and there's a lot of info to go through. But here are a few of the dyno runs from Saturday at Lee's Cycle in San Diego.

Here's a run with the stock exhaust, a run with the Akrapovic SS full system with the baffle installed, and a run without the baffle installed. It's a good sound test for all 3. I'll save the HP graphs for the writeup but my bike did 36.50 as stock as I could make it. It still had the 13/42 Vortex sprockets, lightweight brake rotor, and Pirelli Rosso 2 140 rear tire.

Stock exhaust and air filter installed, stock O2 sensor hooked up, all zero map on my Bazzaz Z-Fi:

How close are you to completing the write up?

Thanks by the way.

37hp stock vs 40hp fully tuned... All that for 3hp,, Not worth it!!

So your last three posts you are back at it on being opposed to small displacement/low power bikes. Did you sell your R3 already and move on to something bigger that isn't so boring for you? Are you going to stop by and report how awesome and not boring it is? Please do so, so that everyone can say how it is not worth it to have the bike yet you won't even be using half of its capabilities. Hey guys I have a liter bike, but I'll never regularly ride at over 150 mph, I'll never come close to the edge of my tires, I'll never get out of "C" group at the track, **** I'll never even make it to the track, I'll have a bad ass sports bike but I'll never actually ride it like a sports bike. Not worth it!

We get it, small displacement bikes are **** ( for you).
