I have a full Akra race system on my XCo with a UNI filter and removed airbox inner lid. I also run a Booster Plug. Works great. Strong, very strong linear power curve.

So was the plug alone a noticeable difference? Affect mileage?

I have a straight through, uncatted but legal end can, removed the airbox cover, K&N filter and Iridium spark plugs plus a little saved weight. I couldn't go any further because I needed the bike to be reliable. It's a lot better than standard, at one point I swapped bikes with a fellow traveller who was riding a Tenere and we both got off and commented how much faster and stronger the bikes were over standard, having both ridden standard versions of each other's machines and being unimpressed. He had done the same work as me, essentially.
None of this adversely effected my fuel economy either, she remains constant at delivering impressive mileage, she just breathes and burns more efficiently now so runs better.
Personally, i couldn't care less about power curves, i just want to pull my throttle open and notice a difference and i do so that makes me smile.

I have installed booster plug quite a while ago because I have noticed that my bike is more "user friendly" in cold weather so considering the logic of this solution (which in practice sort of cheats the system into thinking that it is colder than it really is) I thought that it is a good idea. From my perspective (I do not consider myself to be an experienced rider and I ride mostly in heavily congested city traffic) it made quite a change. In 1st and 2nd gear the bike seems to be more agile, 1st and 2nd gear seems to be quite a bit "longer" which is a welcome improvement because I do not have to change gears so often while riding in the jam or between other vehicles. Mileage ? Actually in the city traffic is higher (lower fuel consumption sometimes even by 10%). On the road I could not observe any difference.

You're the second person I hear who says that range improved. Logically it should be the opposite as you're putting in more fuel but I guess it makes sense if the bike has a very lean burn system. Maybe we're twisting the throttle harder than we'd like on pullaways which is costing us at the pump and this helps? Interesting you've had it a while and it's been reliable. I might consider one of these myself. My bike is due for a major overhaul later this year...

You just cant kill that Rotax 654 engine (tho Loncin own the rights to it now) ... awesome to see BMW continuing to refine it ... 58 hp now. Same economy.

Like an XC with a steel swingarm, link suspension, steel subframe, 10% more hp and about 15 kgs heavier I estimate ... should be able to shave 5kgs off straight away by eliminating the dual exhaust and putting an aftermarket can on.

Suspension and wheels - as usual for BMW - looks to be the downside. 190mm of travel on an off road bike? And looks like a 17 inch rear wheel - tho it says 18 in the specs. Also looks like the weak BMW F650GS single front hub ... I am guessing that in keeping with recent BMW tradition the suspension will be all Sachs ... which will surely mean its even worse than the poor units on the X bikes. Oh well .... [edit - just read the specs ... it is Suchs all round]

I would like to look at transplanting the engine into an X-C ... wonder if the head - frame bolts are in the same position.

I'm not sure the head is changed. Compression is up a wee-bit but that may be done with the piston. Also, cams are different.

If the head is modified, I'm sure it would bolt-on direct to the old motor.
I'm just not sure it is worth the trouble. Try the new cams and maybe mill-down the old head.

My XCo has plenty of power, as is.

My XCo, with the alterations I mentioned, runs better and gets good mileage. If I baby it, I get maybe 60 mpg. That rarely happens.

I recently made a trip with a friend on his bone-stock BMW 650GS single. My mileage was very similar and never more than 10 percent worse.

Doing the Booster Plug only ? I'm not sure I'd worry about doing that. My primary concern was to add a little richening after opening up the intake and exhaust.

In addition to the UNI and removal of the inner airbox lid, I also fashioned an intake scoop that routes incoming air, when underway, to the airbox.

I can't over-praise how well this little bike runs. Very strong.

Maybe the mods allow it to pull the 17T front sprocket so well. Adding that bigger sprocket was one of the best things I've done.

I very recently bought a Guzzi Stelvio that is mind-blowing but I still luv my little 650.

Do you have more info on the weak F650GS single hub?

Personally I'd rather ride a bike with that engine first and feel the engine work. Often upgrading the number of horses with no gain at the torque side doesn't make an engine smoother. I don't care for horses (they're for track racing ) toomuch, but usable torque and power through the revs are more important to me.

Battery:
After trying everything I went down to the battery shop and has my old battery tested. Looks like it only put out 1 crank AMP. Bought a new battery right there, took it home, installed it, and the bike started as if brand new.

Thanks for the help guys!

I suppose it is about time I join this thread. I've graduated from the Dr200 I've been riding, and am picking up an '09 XCo this weekend. Pics will come when it makes it home. I'm looking forward to joining the list of proud XCountry owners!

Welcome! It's truly amazing how diverse the places your XCo can take you! I've zigged downtown blocks, then passed semis on slab at 80mph, then within that hour climbed steep mud deep in big mountains 20 miles from other people. My XCo is my only bike, and so far I'm quite happy with that! Welcome to a great club!

Something like this then ... (a mate of mine on his GS and his girl (Beemster) on X-Country ... both with 18-21 inch wheels)

Diverse it true. I commuted to work on mine for a year and a half. No issues. I took it green-laning, sometimes with a pillion and up against 400 KTM and enduro bikes. No problems (I couldn't always keep up). I toured Europe with a pillion and half her house strapped to the back. No issues. I rode it across the Middle East through mud, dirt, rocks, desert, sand-storms, flooding, storms, snow, heat, traffic, motorways and everything in between. I was even hit by a car and she still just got up and got going with no real damage. I love this bike. It's not the fastest, not the most comfortable, not the best in the mud and not the sexiest but it does everything with the minimum of fuss and puts a smile on my face every time I see it.
