Is my XTR-07 correct adjusted in Dyno?
 

Hello

Wondering if my XTR-07 is correct adjusted in dyno. The guy who run my bike in his Dyno is very careful to adjust the bike to really good fuel curve. Run the bike with 15/45 and it feels good but compared to my friend who only got a 2-1 system without any other mod it feels not right. I bought the PC V from offtheroad.de and told them to put a fuel mod but my guy told it was really wrong from the beginning and change it. Here is my mod on my bike:

*OTR 2-1 without ca but with Db killer in, about 34mm instead of 50mm plug.
*O2 optimizer
*KN filter "no open filter on right side because I drive in mud"
*Power commander V
*15/45 gearing
*NGK Iridium spark plug

Is my CO1 cut off from the system with the o2 optimizer so I got have to touch it? The diagram shows real hp on the backwheel and did it on fourth gear because some bike have regulations on the highest gear, is this ok?. I gonna try to loan a laptop to check my fuelnumbers but I was with this guy probably about 1,5 hour, he didn,t top rev the engine, but really adjust in to maximum fuel curve.

The picture was to small so I send a link!

Looks OK but the A/F ratio is a bit rich across the rev range, we have mostly found the XT's produces it's best HP & Torque around 13.2:1.

A O2 Optimizer does not affect the CO1 at all, it only controlles the closed loop circuit & is set to around 13.6:1 by Dyno Jet.

Air/fuel ratio guestion...
with the AIS "air injection system" working is it
possable to get a true reading of the Ex gases...

No it is not, everytime you Dyno your bike or use a A/F ratio tuner or gauge the AIS needs to be blocked off or completly removed.

Thanks Kev

Should I change anything or let it be. If I take out the DB killer the front wheel goes up really easy but I still use 15/45 so probably in the winter I gonna change to 14 in front. It is as really heavy bike
but doing wheelies with it is well balanced. How much do the clutch stand?

Hello

Perhaps KEV could see this picture when I took a backup on my PC V.
Does it see any good or is there something to do?

I see they have not mapped the closed loop area at all from 2500rpm up to 15% throttle, 9% is Dynojets default closed loop setting for Dynojets O2 optimizer, the rest of the map looks fine. The Dyno tuner could have tried to get the map closer if he wanted, if the bike rides well I would not worry to much about the closed loop area.

Yes the bottom register is great but how much more respons can I get to change? Are there any other maps who is almost the same I can try with or is it a bad idea? Thanks again KEV.:headbang:
