guys i own a cbr1100xx blackbird at present to which i would just like a change to something smaller cc wise. i was offered a swap for my bike to a xt660x 2007 with 11300miles the xt has engine bars also giva rack scottoiler fitted. just would like some advice on the xt660x pros and conns as i have never owned one .i read about fuel issues on the xt so i asked the guy about it and he told me bike is fine if kept in the correct gear in town below 30mph as he has no issues with it this way. also what sort of mpg would i expect to get from the xt660x. my blackbird does about 70miles for a �10 petrol. any common problems to look out for with the xt660x . thanks guys any advice would be very much appreciated

Your guy is pretty much right about the fuelling - keep it the right gear with the revs up and the surging is not an issue. However, there are a lot of cheap and free fixes, all listed in the mods section here, that can address the problem and make the bike ride much more smoothly at lower throttle openings.

You should expect to get anywhere between 100 and 120 miles on a tenners worth of fuel on an XT. They return between 50 and 60 mpg generally, depending on how they are ridden.

These bikes are pretty reliable as long as maintain properly - regular oil changes, greasing of swingarm, linkage and head races etc. Other than the fuelling issue there aren't really any major issues with the XTX.

thanks for the info very helpful

yeh havent seen the xt yet guy told me it may or may not be my cup of tea as the big single motor do vibrate and are totally different to what i am used to <4 cylinder bikes>. going to see her next week just thought i would join the xt forum to ask a few things about the xt.

do u have any regrets pepsi now after owning one?. is it the xt660x u have?

I part ex'd a SV650 for a brand new XTX 6/7 years ago, haven't looked back once.
Completely different animal, it might not be able to keep up with them on long motorway stretches but for fun theres nothing like. Handles through corners lovely, and you can use all the power without losing your licence :P

I rode mine for a few years before I saw the forum so hadn't read about fuelling and surging problem, and I hadn't noticed anything odd. The only issue I'd found was 30mph is between 2nd and 3rd gear, but thats sorted by sitting at just over 30 in 3rd

thanks guys for the info. can i also ask about the tires. i read somewhere the xt can be hard on tires what sort of millage would one get out of a tire from new if looked after ie propper pressures and norml riding ? or is this like asking how long is a piece of string lol

thanks again for the info. is there anything to look out for on the xt x when i am going to look over it this week u can tell me. its the xt660x 2007

As I mentioned before, check for evidence of regular servicing, either dealer stamps of it DIY, receipts etc. Ask when the oil, coolant and brake fluid was last changed. If the question can't be answered satisfactorily, then be wary. Condition of the chain and sprockets I always find is a good indicator of how well a bike has been looked after in general, and big singles are harder than multis on the final drive. Disc and pad condition is also another quick and easy to see indicator of how cherished an XT has been by it's owner.

Look carefully for smooth steering action - get the front wheel of the ground and check the headrace bearings for notchiness. Same the with the swingarm - check for play in the linkage and evidence that it's been stripped and greased.

2007/8 bikes were the fist with O2/lambda sensors and tend to be a bit more prone to surging than others with the ECU 5VK-8591A-10 ECU. See here. Have a look to see whether any fuelling devices have been fitted as this will save you a few quid in the long run if you want to sort it.

Other than general cosmetic condition, spokes and engine finish particularly, just look out for the usual stuff you would on any used bike like engine rattles/knocks, wheel bearing play, brakes, clutch action etc.
