Money spent on suspension is like money spent on your Mom. Good things will come from it.

oil change is a must at least once a year

Yeah, that's for sure on the to-do list. I'm leaning towards fluid change and respring the rear (front sag is good...suspect a previous owner fitted stiffer springs up there) and spend some time setting clickers and see where I stand. She really wanted to swap in the whoops a few times and over-rotate coming off berms so upping rebound screws is on the list for next time.

My suspension could use at minimum a fluid change and I need to go to a heavier rear spring...debating sending it off to be revalved. I'm challenged by sand whoops and really want the bike to behave its best over them. Got to ride with a couple 250 MX-ers in the woods over the weekend and while I never expect to be nipping at their heels it would be nice to put in a better showing.
I'm lucky, I have a really good suspension guy damn near right next door. ZR1.

I'm a big guy, 240ish, and I talked to him. He said that the valving on the DRZ is pretty good from the factory, but it's hampered severely by being undersprung in almost all cases. I dropped my bike off, and for $400 he resprung it, changed the oil/seals, and basically did a very thorough suspension service.

It really did transform the bike. I can't say enough good things about it. I used to have a LOT of front end chatter on corners that weren't smooth, now I can cut through corners wih whoops, rocks, ruts, whatever, no issues. The bike hooks better, turns better, just does everything better.

A revalve will only make a difference if your riding is outside the type/speed of riding that the bike is valved for from the factory. But proper spring rate, and oil weight, will make a big difference, because it will allow the factory valving to work how it is supposed to.

The suspension is also prone to plummeting through its travel at both ends when pushed because compression damping forces near maximum suspension velocity are too low for anything but trail riding which tends to have the lowest suspension demands. Increasing the oil viscosity hurts the low speed circuits (the bluntness - it might feel better on the road where suspension velocities are very low) and 15-20cSt is about optimum with tailored stack configurations.
Front adjusters are low speed only... ramping up the low speed damping will help the feel into a corner and decrease the tendency to tuck, but it will do very little for the rest of the damping curve. Excessive low speed damping just increases harshness.
The rear has both high and low speed adjustments, but these have a limited range.

The bikes around here are about half and half for RT and OEM valves. I normally recommend RT Gold Valves because when buying these valves they come with the support to configure the stacks for weight and riding style. People are usually on their own when designing custom stacks for the OEM valves.

A while back I posted several front stack combinations (including stock) for the OEM valves and their associated damping curves that would have met the needs of most riders (tested by better riders than me), but there was no interest so I didn't bother with the rear.

If you guys are really interested in doing revalves… there is a LOT of good info/knowledge, shim stacks, plots, etc… for both the forks and shock in this thread: http://www.thumpertalk.com/topic/103...commendations/

Personally I've tried and developed a few of those recommended stacks. With each successive revalve, the bike feels better and better

When I first switched to stiffer springs for my weight, I didn't feel a big difference in the suspension's performance. However following the first revalve The stock suspension is good for moderate trail use at moderate speeds. Pick up the pace, hit whoops, high-speed obstacles and the DRZ will leave you on the ground without confidence.

Has anyone installed one of these on they DRZ? I'm thinking this would be a great thing for those of US that load the electric system down with heated grips,vest & Gps.

We get a bit of snow, even in the desert.

That thread is partially what prompted the question. I think I may give it a shot on the forks but not sure I have the desire & equipment to do the shock. I've never felt like my forks are too bad (but maybe that's because the shock is underperforming?). I really need to tear into them and see what I'm working with. I may try some of the shim stacks in the forks and send off the shock for a re-stack.

Yeahhh, I can see getting sucked into this. Guess with the time change I've got a bunch of nights after work to play with fork oil in the garage...

I have it on my bike, easy install and works fine. Just remember that you can't run larger than a 120 tire with this or it will rub.

No experience with that particular battery, but I've been using an 8-cell Ballistic Evo2 for about two years now, running heated grips and a GPS with no issues, never dipped below 13.5v. Haven't touched a battery tender since I installed the Ballistic, but I also ride year-round. Adding heated sock liners to the mix this winter, so we'll see how that impacts things.

Starchamp,
Does this battery fit in and stock position? and where is it available?

Blaster,
Thanks for the heads up about the tire size restrictions.

DRZ ride report. (Not Me, but I wished).

110 days of off road to Central Asia


Earlier this year my wife (Kim) and I (Seb) went on an adventure ride from Belgium to Mongolia and further to Central Asia for 110 days of offroad mayhem. We were both riding DRZ's 400E and still grateful to Walter Colebatch for some of his Sibirsky Extreme tracks for Kazakhstan and Russia.

No, this is not a copy/paste or a hoax of Walter's and Terry's last ride, but an adventure of it's own since our final destination had nothing to do with Magadan and in the end we did only parts of Walter's tracks.

We didn't prepare too much in advance, only all our visa and some off road tracks and off we went, direction East for almost 4 months.
