Hiya Kev and gang!!!!

My bike is now using about 10% MORE petrol since I listened to you lot!!!!!! But blimey, I am having about 10 times more fun so I guess that this explains the increased fuel consumption, as the throttle is now always wide open so that I can listen to the great air intake "growl" without that stupid snorkel!! Oh and the Stage 2 filter just arrived from Greece so that will be fitted this evening, fuel consumption will be up by at least 20% tomorrow hehe.....

Hiya Guys!! I received my DNA Stage 2 filter from Greece yesterday (thanks for the rapid despatch guys) and I fitted it last night. I already have the K&N Stage 1 fitted and the snorkel removed. This morning my ride to work was even more fun than usual, the bike sounds and goes MUCH better, thanks boys!!!!!

EVERY XT should have this fitted!!!!!

Hi

The pics are dead. Can u re-upload them? :o)

Hi, ive been trawling through all of the posts about the snorkel removal on my 07 xtx, but cant find the info i want, so here i go. Ive fitted a K&N filter, removed said snorkel & my bike is also fitted with a pair of MTC Cans. I read here that the lamba should sort out the fuelling to suit these mods, and if it cant, the engine light will come on. At the minute i,ve only started the bike in the garage, it hasnt been on the road yet, and it seems to be running ok. If i take the bike out and the engine light does come on, how do i go about getting it reset again? these are all the mods i will be doing to this bike, so i wont be fitting a kev mod or power commander. any help appreciated with this, cheers:T

I would recommend a fuelling device + a O2 controller to correctly tune your bike with all those mods.

The O2 sensor light will only come on for open circuit, short to neg or short to +, it will not display a fault for too lean or too rich.

Thanks Kev, but i didnt really understand that :emot-words: So will riding with the mods i have done now make any difference to power output? or more importantly, will they do any harm to the engine (will the bike be running dangerously lean?) If so, i may just install the snorkel and go back to standard filter again as the only reason i changed these was to get a bit more induction roar. Cheers:T

The bike will run lean but should not damage the motor, you are adding more air & allowing the motor to breath more on the exhaust side, there will be an improvement in HP but will be down 3 to 4 HP from what you could get because you have not corrected the A/F ratio with a fueling device.

The XT needs 13.2:1 A/F ratio to produce it's best HP & Torque you will be in the mid to high 14's without correcting the A/F ratio with those mods.
