I cannot say for sure but the chances are pretty slim. Have you seen this symptom on overfilled engines? If this is the issue, I'm relieved that is not something worse. But from what I know, too much oil leads to damaged oil gaskets and o-rings.

I have acquired a 2004 XT660R. It has horrible fuelling. It cuts out on downshifting too. I've manually increased the idle which has helped a little.

My problem is that my Dash is broken. I can't access any diagnostics menu. And there is no way I can afford to replace it.

Will the mod work for me even if I can't do the basic dashboard adjustment ?

You asked the same question in a PM to me & this was my reply.

Hi Ted

There are quite a few things that cause these 660's to surge. Unfortunetly you have the worst ECU of them all ending with -00, my adjustable fuel mod will help but wont cure the dreaded surging on a ECU ending with -00, have a look at this link to get an idea of what else needs to be looked at first:

Wow

First of all...WOW! THANKS KEV <3

My Tén = Hardcore level (now)

After some time, i finally had some time to mount everything on my bike. (vacations are cool)

It's a 30m job...had zero problems.

Here are some pictures for you guys









And here...my BEAST (and no...i'm not the beauty...)





So, for those who may have questions regarding this mod (FUEL MOD + O2 + DNA Stage 1,2 & 3...

DONT! you will have a new bike after a 30m work...

Thanks again KEV...really <3

Oh...i'm from Portugal...i tested the mod for like 1 week now at 23-35º (celsius)

I find that the fuel mod knob works better at 6 o'clock position but i will continue testing for sure.

For now, juts another happy rider!

PEACE!

Glad you are happy with all the mods, these 660 motors respond well to the extra air & fuel.
