Here is my bike Stock. (with Power Commander) and with the full Ti system (with PC) Big gains down low and at the top. I was hpoing for a bit more at the top and I will put the air snorkels back in to see what they do to power.

I still have to set the TPS and other minor tweaks.
Sound is wicked!!

yeah...a video of that dyno run would make alot most happy. :)

and you have to be able to feel that torque leap from 4 to 6.7Krpm. real nice.

Thanks for posting...interested in your riding impressions too. I would think after your tweaks there would be more hp based on representations for the R with racing exhaust (whatever that may turn out to be) or Ti system. In any case, the bike looks and sounds great

MV's seem to have about a 15% drivetrain loss. Normal is 13-15% so things are pretty much in line.
144hp (what MV states the bike should make with the full system/chip) subtract 15% and you get 122.4 HP.

136 stock, subtract 15%= 115.6. About what my bike was putting out.

Both Ago 1000's I dynoed put out 143 and 146 HP. That is also about a 15% driveline loss.


I have a little more work to do as far as TPS, snorkels and mapping. Bike pulls strong though.
Sounds like a F1 car!!!

John,

What you got is GREAT, better, improved and the sound is better too. The 'naked' 910 is set where it is for safety reasons. Be careful with that BEAST!

Looking forward to riding with you again, Peter

I saw that too, I was joking to myself, "That is where the turbo was kicking in..." :naughty:

Ya, that's nice...Speed safely.

Agreed, any more power and the bike would be a bit scary. As it is, it is hard to keep the front wheel on the ground.

It is not about peak numbers, the delivery of the torque and how the power builds is really great on these bikes. I am very happy with the results.

John, I can't believe I missed this thread.
This is VERY interesting to me.
You dyno'd my bike at 121, with MV corse inox midpipe and headers. This means that the Ti silencers add about 2hp.

Hi Airfuel, do you have any dyno test with it original without PC?
What is the airfuel ratio and CO level?

Did you run it with any special air filter?

Thanks

Here is the very first run I did on the 910R Completely bone stock,no PC.

The last run was just yesterday. Full Ti system, BMC filter. Custom map.

Stock was rich at full throttle, mapped is just about 13/1 a/f

Thanks Airfuel.

Very nive A/F line you got there! What is the CO level you got at idle speed, did you check?
What petrol do you guys normally use there in USA?
