All right... another question from a new owner. When I changed out the rear tire I noticed NO rim locks, so I assume we just run without them? What pressure are you running for 90% off road/dirt? Can't go too low or you spin the tire and rip out the valve stem.. thoughts?

For 90% off road, you're going to be airing down. I suggest you drill for at least one rim lock.

That depends on weight in part and surface. Unloaded with the Adventure/ but full with 7 gallons of gas, low twenties in the rear. A little more in the front to protect the rim.

I carry and electric pump when traveling to air up as needed. I have run those low pressures on the road but go a little slower.

Best is to experiment on your own, dropping the pressure until it feels right to you. I have a Scotts steering stabilizer so I am cheating.

Rim locks are a PIA, I have never spun a tire but I clean my rims every time, remove the rim strap and oil the nipples, then wie everything clean. Wire brush the rim itself.
After the tire is mounted I tighten the spokes just a little all the way around torquing by feel with this...

Been using WD 40 to mount, unmount the tires.

I never air down, I just run. I've also run plenty of road time on low pressure and it hasn't been a problem. I did try a set of my old mousses once but they were way too soft. I say giv 'er!

Skibum,
My riding partners who are still fast and over 60, like myself, all air down.

One guy rode with Ekins and McQueen in the desert, the other road raced and MX'd back in the days of shit suspension, I'm an old enduro racer and MXer. Well maybe we are just too old?

In gravel and in the slick snot unless you are superman or like riding on marbles all day, I'd air down.

I have 5 broken collarbones from highsides and a broken foot.
Traveling outside the first world, the worst injuries to mc and men were the result of crashes on gravel at 50-60 mph.

Air down bro.

Cracked ribs are a bitch(too).
You just can't laugh at yourself.


Old bill

edit:
Forgot the broken pelvis in Bolivia,bought the KTM when I got home.
It's the most forgiving motorcycle I ever rode.

Thanks for the tips. I was out offroad half the day today running about 28 psi, everything felt fine to me? We weren't running too hard either.

In Mongolia I definitely did run lower psi for the 8 day rally, but it didn't make up for rider error

Yep, good ones.

I've dropped much lower than that with rimlocks and sub 300 lb two strokes.

I remember 12-14 front, 8 rear.
Metzlers knobbies, back in the day.

Ok so here I am at Nordkapp paying the admission fee and saying thanks to the guy at the cash desk, turning the key, ignition on, starting the bike and hearing only annoying clicks (similar to ones when you have a flat battery).
Smiling when doing few kicks with kick starter and telling the guy at the cash desk that it's the northernmost point of Europe where I could breakdown
So here is the thing: all fuses are ok; battery was changed before the trip; used couple of times heated grips and charged a bit an ipad mini just when it happened; both plus and minus connectors doesn't seem loose (been there - done that)...
I'm in the middle of the trip, next is Russia and then Finland...
Any ideas, gurus?;)

I'm no expert, but:
- assuming the heated grips are off for sure when the bike is off, is there anything else connected that can be consuming the batt while not riding?
- does the batt recover when you ride for a while? I would check this without connecting anything to the bike, in order to clear the way to the origin of the problem.
- most of all, assuming the batt is ok (new) can be not charging while riding; do you have access to a place where you can get the bike's batt charging capacity meassured?

Keep us posted!

What is the battery voltage while the engine is running?

My voltage regulator died recently, but would charge the battery normally for 15 or 20 minutes before giving up the ghost. It would not fail strait away though. After riding a bit voltage would start dropping. Over about 10 minute time it would go from 13.5 to 12.5. Then it might jump back to 13.5 and start dropping again. Lowest I saw was about 12volts.

Also, just because the battery is new, doesn't mean it couldn't have failed.
