Hello XT owners

I am the proud new owner of an XTX660 2005. I just bought this bike is superb condition with 55ookm and fitted with airbox mod, potentiometer and aftermarket exhausts. However it seems to be poorly set up with almost no torque and running roughly perhaps over rich.
Can someone tell me how to reset all the adjustments (MAP??) to factory stardard so that I can start from a known point. I can remove the pot if necessary. Thanks in anticipation. Kiwi Pete.

and to

Question one. Does the bike have a power commander fitted to it?


p.s. thread moved to correct section, please follow the link for 2 days then it stays in the new section for good. Cheers

Hello - and thanks for your help. I am not sure if this is a Power COmmander but there is a Pot mounted under the seat in the manner of the Engine Control Unit (By Kev) mod. paperwork which came with the bike.

Right! In that case, that pot is a Kev's fuel mod. The idea is that you adjust that knob in either direction until you get a satisfactory smooth ride. There is no such a thing as a "zero" settings to go back to but if you follow the steps below you can adjust the Kev Mod to the best of its capacity.

However before you adjust the knob, please make sure of the following:

1) correct chain tension - chain is not too slack / taught
2) tickover or idleing speed is kept between 1450 - 1500 rpm to learn how to adjust the tickover please follow these steps:

Switch off Engine Run switch, switch OFF Key switch.

1/ Press both SELECT & RESET buttons and then switch ON Key switch, keep SELECT & RESET buttons pressed for at least 8 seconds. Display then changes to "DIAG". Release SELECT & RESET buttons.

2/ Press the SELECT button once until CO displays, press SELECT & RESET buttons again & hold, CO1 should display.

3/ Once selected CO1, switch on the kill switch & crank the motor. Once started the rev counter should be in the right side of the LCD screen.

Once you have the diag mode on the screen locate a screw which is on the left hand side of your throttle body

Turn this screw clockwise & this will increase the idle speed. I would set your idle once the engine is warm to around the 1500rpm mark

Once you are happy that your tickover sits regularly at 1500rpm, and that your chain has the correct tension, with the engine warm go for a ride and start with the knob all the way off and see how the bike behaves at low rpm's if it judders or stalls then you increase the knob setting a notch or two. Try again, test ride it and see if it improves. Keep turning the knob until the bike has the smoothest ride possible, but remember do not do this test before the tickover and the chain slack are set correctly.

Hello Capt Moto Many thanks for your detailed procedures - which I will do next weekend. Much appreciated. On another topic do people ever change over the front wheel and forks as really I was after the 21" model but in the end couldn't resist the moto I bought due to overall condition and price. I guess it would be an expensive exercise.

Yes it has been done before and it can be expensive because it requires a new fork / brake disc etc. However if you find a front end at a bike breaker (very rare because bikes you find at breakers have nearly all of them been t-boned somewhere and that means the front end is the first thing to go)

Many thanks for this further info. I can see what you mean about the scarcity of forks. Sorry for the delayed reply -out of town.

Regards Peter Wilson

Hey sport..
If I can ever fined a set of USD forks to fit my R..
I will have a set of R forks I don't need...

PS..I'm in Blenheim...
