How do all,
These are my thoughts and feelings about my xt660z 09 so far...Overall I am happy with the bike, in the couple of months I've had it I've had to replace the head bearings and the cush drive rubbers, no probs easy enough, fitted kevs O2 and Fuel Mod as well as dna filter and snorkel removal...Now, like I say happy overall however I can't seem to get the bike to cruise at a set speed. so days are better than others I think its much better in the mornings then during the day.(I am HGV Driver so stupid o clock). Would the bike run better due to the colder temp in the mornings? I originally had kevs fuel mod set to 6oclock. I have blocked the AIS pipe as well and have now set fuel mod to 3oclock.

What I am seeing/feeling about the bike.
definitely a on/off feeling if I try to hold the speed at 30 in 2nd, 40 in 3rd 50 in 4th revs are about the 4000 mark.
clicking another gear 30 in 3rd 40 in 4th drops the rpm to around 3000 reduces the on/off feel quite a lot (but is still there)
The bike will pull in these gears but I feel its to high a gear.
I have also raised the idle to around 16-1700rpm this seems to have reduced the on/off feeling a bit so I am sticking with it for the moment.

I was also wondering whether its my riding style, my other bike is an FJR.

Sorry for the long boring post but trying to give as much info as poss
