2007 is the year of my XT.

I have just had a camping weekend away and the bike returned 65mpg ( 145miles=10.14 litre==65.1mpg) but i was being "sensetive" with the throttle due to the surging. It does seem that it is happier at mid-range openings.

At 65-70mph its fine. Its just the lower rev range that makes me think that the PC has been set up for more power mid to higher rev range. when i crack the throttle open it takes off like a scalded cat !!.....Brilliant :rofl[1]:

I have no idea about checking the settings of maps etc, so if you know of a reputable Dynojet dealer who understands XT660 i would get it over to them to see whats what.

Thanks for all your help and advice so far.;)

Thanks for all the advice.

I read the info on this site and found......sprocket carrier bearing knackered, rear wheel bearings knackered !!!.

So... i stripped the lot out, cleaned and greased all relevant parts, new bearings, adjusted and cleaned chain/sprockets....Sorted!.

Much smoother on the throttle and massive difference in the surging issues.

many thanks.

Stan.:happy:

Fitted
 

Well i fitted it finally.... not had chance really to check, but it did seem better on the way home, i'd just turned the dial to 3 pm....

Ill try and have another test tomorrow.. the exhaust still pops on the over run,,,
the surging wasn't that bad before to be honest, kinda figured it'd iron propper;y as it was a little annoying and seemed more pronnonced after it our from the new 2 to 1 exhaust fitting.

Stanbloke, check your chush rubbers as these made a massive difference for me, just stuffed with cushion flooring works well.....

braaaaaaaaaappp

You need to block off the AIS pipe to stop the popping in the exhaust.

..
 

Then it will stay unblocked cause I like it.
After a ride today. 3pm on the dial seems about right..
It's definately much smoother through the gears and in traffic.
She sounds happier. Not struggling :)

Thanks again :)

Nethen,

I've done the cush drive rubbers along with wheel bearings, sprocket carrier bearings too......massive difference.

Disabled the AIS today so i will see what the result is tomorrow. I opened the airbox to find it awash with filter oil !!!!!. replaced the KN filter with a std filter, for now.

Looking at Mitas E09 tyres as the ones i have on are past it now.

E 09 rear
Army 644 front are our default tyres now.

Pretty good on any surface :)

Happy Braaaaapppping :)
