Dynojet Power Run...before DNA Airbox
 
Had my very recently bought 2008 XTR dyno'd today, it only had 120 miles on the clock when I bought it, so I now have 700 odd miles on the clock (still feels tight) but supposedly run-in.

Anyway, standard bike and tyres, strapped on front wheel only, 28.6 deg. C, 1035MBARS 10% humidity

42.8 hp
40.57 ft lbs.

Will return with CCC cans baffles in, Power Commander 111 usb, Stage 3 DNA Airbox shortly.

I love a bike with about as much torque as HP!!

Thats the way to check the gain with a before & after. Here was my result with the exact same setup as you.

Kev, my torque at 6100rpm 36.34lbs/ft

Also, where do we want the A/F baseline.....i think from one of the many threads , around 13.2? Any other tips? I now have the results emailed to me, so should you wish, i can forward them on to you......they are in "figure" form, not graph.

My "standard bike" is totally un-fiddled with, I have fitted the PC111 but it has not been plugged in yet. I run the 97Ron Super Unleaded though, instead of 95Ron. And not supermarket fuel, but Esso/Shell/Elf etc. At the higher revs (6400rpm) it was running 12.5 AF , lower revs (2800rpm) around 16.5

Don't worry to much about the readings between yours & my readings, it is the gains I always look at from a before & after run, as every dyno reads differently.

I set my A/F ratio around 13.2:1 for best performance.

I run two maps in my PCIII, one map set at 13.2:1 best performance & the other at 13.2:1 below 3000rpm & 13.8:1 above 3250rpm for town riding better fuel consumption, I can switch between the maps at any stage while riding.

Make sure your AIS is blocked off when on the dyno otherwise the A/F ratio will be wrong.

Thanks Kev

I've been trying to find a stock bike AF reading, to see by how much my bike is richer than with 95Ron...

I like your idea of an "economy" and "power" map....i can use the economy one for the trip to the IOM TT races next year....:023:

My 09 XTX completely standard ranged between 13.6 to 14:3 on 95 Ron Fuel with O2 sensor connected. Disconnect the O2 senor & it can run down to 12:1.

Thanks...I will be fitting the Kawasaki O2 eliminator, and blocking the AIS pipe. I hope this is correct.

If the airbox arrives tomorrow, it will be fitted early week.

The way I have understood things, it is not recommended to use the existing O2 eliminators because they do not work properly. It will disable the O2 sensor, and it will keep the warning light from going on, BUT it will cause the ECU to fallback to a fixed map that is to rich for XT:s (during cruising conditions, which is when the ECU considers the O2 sensor values): the same thing that would happen if you just disconnect the O2 sensor.

Kev or anyone else, please correct me if I still don't understand things correctly.

richardsracingmad 18-07-10 18:09

yep...thats how i understood it too.......but then Correct the map and it should be better. (??)

Well that sounds logical to me, I don't understand why that shouldn't be possible... :017:
