On the alternator issue.

Last week, I attended the Chicken Rally in Huntsville AL and had a chance to talk with my friend, Rick Jones, who operates Motorrad Elektrik (ME). ME is a great source for electrical items intended for BMWs, especially airhead models.

I asked him about the Rotax motor and the issue of the small alternator in my XCo. He seemed familiar with the issue but said he has been unable to find any supplier who makes anything to boost the output of the 280 watt alternator.

On the idea of replacing the 280 with a 400 alternator as used on other 650 single models, Rick cautioned that doing so may require replacement of the case around the alternator as he suspects the 400 watt unit is physically larger than the 280 and the case housing the 280 may not have sufficient clearance foir the 400 watt unit.

The part numbers seem to be different but I am not sure if that is due to design or color.

I have been able to get 200 miles out of my Acerbis Aux tank set up as well.

Anyone have a stock seat to part with?

my brother might have one back in England. Might be a bit too much trouble.PM me your email if you're interested, I will pass it along to my brother if he still has it.

UPDATE on $156 Touratech gas cap -

Well, this damn thing leaks too ! After a little more than a month installed, the TT cap is leaking about like the stock one did. I removed it yesterday and replaced the rubber sealing gasket with some nitrile that is thicker.

Hope this works. Will report back.

For newbies to this issue, my switch was for functional reasons rather than aesthetics. Sooner or later, the stock plastic gas cap will develop leaks. You can mitigate this by replacing the internal o-ring and making a new sealing gasket ( see earlier posts).

This inevitable leakage may not be a problem for many riders. However, if you are using an auxiliary gas tank, it is a huge issue. As the auxiliary tank fills the stock tank above the gas cap level, if the cap leaks, it will trickle down the side of the tank. A leaking main tank cap can also break the vacuum that may be needed to prime the flow from the auxiliary tank.

Anyway, at $156, the TT is pricey. I have fixed my stock cap as described but, since this motorcycle is discontinued, I decided to spring for a TT cap while they are still available.

Now I am feeling a flat spot in the steering head bearings. Looks like I'm gonna have to remove the forks and replace the bearings ! It's under warranty but I'd prefer to do the work myself. While I'm in there, I am going to install a grease fitting to lube the head bearings in the future.

I bet the rear swingarm needs attention too.

Quit causing guilt.

Nearly 14,000 miles and I haven't looked at mine. I suspect they suck.

I was wondering about the torque of those screws. When I took it off they seemed way too loose, I tightened them a little tighter because now the seal is much more important. Maybe I'll loosen them a bit.

Going out for a long ride today to more fully test the system.

Any chance that the problem is not the cap but in fact the metal fitting on the tank? Could it possibly be a half millimeter bent in some way? Because though some people have this leakage problem, most don't.

From the 1,549 mile, 5-day ride I completed today:







Observations about fuel mileage and other thoughts will follow.

BUT, I had a seriously good time on a seriously wonderful motorbike!

So the more I read, the more I like this bike. I've been recruited to help someone buy her first bike and after a lot of reading, I suggested the XCountry. Now that she's fallen in love with it I can't find one anywhere in the northeast or even remotely close.

Any suggestions?

Nah. The tank flange is fine and the TT cap worked for a while. Remember too that I have an auxiliary tank that feeds the stock so there is some positive pressure on the gas cap from the inside since the stock tank becomes fully charged by the auxiliary.

Im hoping the thicker nitrile gasket will fix the problem. The TT cap is better constructed out of machined aluminum as opposed to the all-plastic stock cap. On top of that, the stock lock cylinder starts getting funky after a lot of use. The TT eliminates the lock cylinder.

Yeah they can be hard to find. There was one on eBay a few weeks ago but nothing now. Good luck!

If it were for me, I'd love to do a fly and ride. But I think as a first time buyer she is going to be put off by buying a bike more than 4 hours away and choose a different bike if she can't find one locally. That would be a shame since the more I read, the more I think this is the right bike for her.

The target is a 4 hour radius from Boston/Providence.

Thanks for the help so far.
