Here you go, a few photos of the handlebars. Hope it helps!

For my MTB, 20-25% of travel is the recommended sag (with rider aboard - won't sag at all w/o). Surfing found this for MX: "5-10% for bike weight and then 25% for bike and rider weight"

Thanks, is that DR specific, or is that generic for all dirt bikes?

That's pretty generic for all bikes, though imho it should be closer to 10% than 5% for bike's own weight imho (this means a stiffer spring for a given rider weight and sag). This works out to about 1" under the bike's own weight and 4" with rider on most 12" travel dirt bikes.

Sag isn't something that you ordinarily alter to suit varying terrain, at least not much. Also note that it isn't a significantly means of altering suspension behavior - its more about messing with chassis geometry (though your suspension will suck if your sag is way off). If you want a bit quicker steering try running 2-5mm less sag, for a bit more stability run 2-5mm more sag. I wouldn't change more than 5mm at a time as that much will make quite a difference. Modern bikes with less flex will make changes in sag even more obvious. The DR is so imprecise its not quite as obvious, but still makes a big difference

Note that more sag will generally make the bike less plush because it sags into the more progressive part of the linkage where it gets stiffer. Also you've got less travel available to soak up hits. Pre-load doesn't alter spring stiffness, it only changes ride height. All this to say running a bunch of sag won't make it more plush.

This is generic - and you have to know your full travel to use it. Manual says:
DR350SER ('94):
Front suspension stroke. . . ...............280mm(11.0In)
Rear wheel travel . . . . . .255 mm (10.0 in)
DR350SN ('92)
Front suspension stroke. . . ...............280mm(11.0In)
Rear wheel travel . . . . . .280mm(11.0In)

Basically 1 1/8" w/o you, 2 3/4" with.

The manual tells you to measure the spring length to establish proper preload:

SETTING TABLE
Spring length
STD : 269.2 mm (10.6 in)
Softer: 274.2 mm (10.8 in)
Stiffer: 261.2 mm (10.3 in)

I'm no expert either, but I've always heard the general rule for a dirt bike is 20-30% of total travel.

I just received my new foam and cover from Seat Concepts. Thought I'd post some pics of the new foam vs. the old. I won't get it installed for a week or two but so far it looks really good, and the foam is noticably firmer. Good stuff!



Side by side shows how much more there will be to sit on as well as the nice taper inwards at the front of the seat.





Approximate height difference shows much less of a slope towards the front.

So on the way home today... i lost a screw... an important screw... and it left me stranded! Wooo And it just stopped the bike from running and pissed gas all over the floor. Then if you try to start it again it just keeps peeing gas all over!! woo

I believe it is the fuel screw/air mixture screw or somethin... correct me if i am wrong.

heres a pic.. its toward the bottom of the carb. on a 1995 dr 350se stock carb.

Should you put thread-locking compound on the screws that hold the clutch basket together?

The picture is kind of small, but it sure looks like you are missing your float bowl drain screw! That would definitely cause all the symptoms you described.

Noob question: The bike must be at TDC to adjust the valves, correct? And I can find TDC by pulling in the comp lever, slowly kicking down til the lever pops, and letting go?

I would watch the intake valves. TDC is just after you see them close.

Yup ive come to the conclusion that the float bowl drain screw is what i am missing. Thanks!

Do you have any recommendations for cleaning the carb?

You too. I lost a front brake caliper bolt today! Luckily I was only 3/4 of a mile from home, but it was at the end of a 75 mile ride. Not to self check bolt torques more often. I also added some thread locker to the new bolts just to be sure.

Having your lever bottom out without slowing down is an unnerving feeling.
