On the trail I carry a spare tube with a handful of CO2 cylinders; no pump or compressor. Knock on wood but I haven't needed them yet.

Thanks for pointing that out!

(sometimes i forget to air down...but i realize it about 1 minute into the trails. it really does make a huge difference.)

i'll leave the pressures like that for riding roads to link trails. i will sometimes leave the pressures like that to ride home at the end of the day if i'm withing 10 miles or so of home.

if i have farther to go, i will air back up (to around 25psi both front and back) first. a bunch of the guys i ride with do not have plates and trailer to rides. i can generally borrow an air compressor from one of them. if everyone is dual sporting it, though, we will stop at a gas station to air back up if there is one within a few miles of getting back on the road. if not, i carry a planet bike mini versair MTB pump and use that (which i also use to fix trailside flats).

i have ridden pretty far on twisty roads at pretty good speeds with 10 psi in the back and 12 in the front. it does not equal death. the bike does feel squirmy, though, and i would rather air back up. but i don't bother if we are linking trails.

(also, i have rim locks...i like two per wheel as they balance each other. i would not run such low pressures without rim locks.)

i prefer to carry a bicycle pump (particularly the mini versair...as it is a dual stage, high volume pump that fills the tire rather quickly and is easy to use and it's cheap--and i've used it many times and it has never let me down) as opposed to an air compressor (too big and weighs too much) or CO2 cartridges (if you run out of cartridges--it can take a couple to fill a single tire, and you might have more than one flat--you are screwed)...though having both CO2 cartridges and a pump would be a good backup.

here is a link to the mini versair:

Thanks LRT and all others that replied to my air pressure question.

I have 2 rim locks coming and will have installed with my new tires.

This forum is full of great information for a noob, Thanks again to all.

Looking forward to Cromag and meeting those that attend,
Dave

I need a rear sprocket.

Any chance someone on here lives around norther Oklahoma that has a rear sprocket that will work on my DRZ400? A used one would be great as a spare until I can find a new set of sprockets and chain.

Anything from a 44-46 tooth should work with my current chain

I'm from nh and am currently doing the TAT. Ride report here http://advrider.com/forums/showthread.php?t=803820

I have found no discussion on setting the DRZ rear race sag. What is the easy way to measure sag and set the pre-load?

Measure from the axle to some easy-to-see point on the tail (edge of the plastic, tape/marker line, whatever). Lift the rear of the bike and measure it (fully drooped out), sit on it in the riding position and measure it (or rather, have someone measure it). Set it by adjusting the preload on the rear shock.

Rule of thumb is 25-35% of total travel. For most dirt bike, this means about 4 inches.

I have had a good 2 years so far out of my Topeak hand pump, lots of coastal sand riding, it gets a good workout and works very well.
How do you guys carry your pumps on the bike?

Hi, I had a small canvas cover made up for mine, which is then attached across ways to the handlebars with some double sided velcro tape, works well.

Can you set the bead when changing out a tube with one of these hand pumps?

Really? I had trouble seating a rear tire on a GS with an electric pump. I'll have to look into one of these. Thanks...

With this being small bike pump, how was the volume when using on a motorcycle tire? How long did it take to pump up the GS tire?

It was definitely technique. It was the first time I had put a new tire on the back. Seems like it was just the last few inches that wouldn't pop on. Had to deflate and relube.

I'd like to see how you have your tool tube rigged up as an air chamber. Got any pics?

955616846,

How about showing us a photo or 2 of your tool tube air resevoir setup? That sounds interesting.

The DR-Z seems to like a little less sag than most. 90mm is recommended by Eddie Sisneros and works great for me.

Saw this and couldn't help posting it. Maybe just carry one of the small 3 oz cans of WD40 and a lighter?
