I bought a 1993 dr350 last week, originally thought it was a Street model but now I have confirmed it is the dirt model. I was able to start it when I went to buy it, and once when I got it home, now I can't get it started again.

I've seen a lot of posts saying to pull the decomp lever in, let go of it, push the kick starter until the lever pops out, then kick hard. My decomp lever seems to pop out as soon as you move the kick starter, no matter where the piston is. Then if I try to kick without it I get compression and bust my ankle (got bit bad twice now).

Bike has gas, petcock on, choke on, etc...

Does the fact that my decomp lever pops out immediately indicate that the cable is adjusted incorrectly?

Am I supposed to kick hard with the decomp lever pulled in or not? I've busted my ankle twice already. I don't feel like owning a bike that will bust my ankle every time I try to ride it.

Ive seen this come up in the forum a lot so go motivated and made a video

That's pretty much how I do it too. The only thing I would add to your video is the admonition of NO throttle when kicking. When it had the BST33 carb I would begin the cold start process by leaning it over far enough to overflow the float bowl, thus "flooding" the carb... the same effect as a couple twists with the TM33.

As your video illustrates, it's not necessary to "jump on it". That's a recipe to break something. It only takes a brisk kick adequate to spin the engine thru the next compression stroke with crankshaft momentum.

FWIW, 94 and newer models have a lower primary gear ratio and each kick moves the engine thru more rotation than the 90-93 models. I think they are easier to start than the early models because of that. The engine in my 96 frame is a 93 off-road but I replaced the early model clutch and primary drive gear with the clutch and primary drive from the newer model for that reason.

Jump on it. (NO THROTTLE!)
If you do it properly you'll never have your leg suddenly stopped (trust me I know your pain)
Just don't kick it wherever it is in the stroke. That's when you'll kill your ankle and I did it like that for a while before I knew how to start it and I never got it started once like that.

You'll get used to it, just gotta get the method down.
Thanks, this description helped me out a lot.

The funny thing is, I had a DR350 when I was a kid and I figured this out quickly and never really had a problem starting it. But I found out when I bought this one that I had completely forgotten whatever technique I was using before.

So I cleaned the carb yesterday (TM33 pumper) and replaced some seals, needle valve, etc. Got the bike started and it is running very rich, and stuttering/popping. It is also idling very high, with the idle screw turned all the way out. Where should I start looking for problems? I replaced the pilot screw and set it out about 2 and 1/4 turns, which I thought I had seen recommended somewhere. First thing I am going to do is check the float level.

(PS just wait till I start asking questions about the wiring... previous owner(s) did a number on this poor bike!)

first farkle ordered, and a aftermarket gas tank ?

I just mailed off a fleabay seat pan to Seat Concepts today! The next upgrade I am thinking about is an oversize gas tank. I notice most of them come with their own vented gas cap with a tube. I'm wondering if I'll still be able to use my stock locking gas cap on any of these tanks, I like the added security.

The stock cap will not work, but Acerbis offers a locking cap for theirs:

Some updated info on mine!
Complete motor rebuild and bored out to 440.
Mikuni carb. FMF exhaust.
RMZ250 fork.
Supermoto-ed with DNA wheels and Distanzias.
Complete tear down to frame/cleanup.
Rewired whole bike very minimalist.



Next up: try to convert headlight to HID (for cheap!) and a bigger fuel tank.

Write up on the RMZ250 fork please! What year was the donor RMZ?
