Carburetor jets
Updated: Jul 27, 2010
Pilot jets
The "VM28.486" series of jets is what will work in the stock dirt carburetor (Mikuni TM33 SS). The "N224.103" series of jets may look like they will work, but they will not fit.

Main jets
The "N100.604" series of jets is what will work in the stock dirt carburetor (Mikuni TM33 SS). The "N102.221" series of jets will also work perfectly well, although the diameter of the head is smaller.
The dimensions of the "N100.604" jet are as follows.
- Diameter of the sloted head: 8 mm
- Overall length: 9 mm
- Thread size: 5 mm x 0.75 mm

Fork boot/gaiter information
Updated: Jan 15, 2010
Searching the Internet, I couldn't find much in the way of definitive information on replacement fork boot fitment for the DR350. Folks mentioned replacing them, but noone seemed to have specifics. So, I measured up my fork and ordered a Daystar replacement boot. Here are the details for anyone else so inclined.
- Diameter of fork tube (top dimension of fork boot): 43 mm
- Diameter of fork lower (bottom dimension of fork boot): 55 mm
- Fully extended length of the fork boot (from fork lower mounting point to immediately under the top triple clamp): approximately 15 inches
- Daystar series MX00069 is a good fit and is available in a wide variety of colors.
I reused the original metal clamps in lieu of the provided zip ties. With the forks in their lowest position in the triple trees and fully extended, the boots reach nicely from immediately under the lower triple tree to the proper mounting location on the fork lowers. The fit at the top and bottom is quite nice…not too snug nor too loose.
The last two letters "BK" signify the color of the fork boots (these are available in a wide variety of colors). So, it is really only the first part "MX00069" that you need to be concerned about.
I couldn't find the DR350 listed anywhere on their website (or anywhere else, for that matter), but these fit many other machines, such as the 1982 Honda CR480R. I bought these from Rocky Mountain ATV.

Hour meter installation
Updated: Jan 28, 2010
I wanted to add an hour meter to my DR350 to aid in knowing when to perform routine maintenance. I found one on eBay made by ProPower.
I made a simple bracket out of some aluminum flat stock I had, and mounted it to the left bolt that secures the trip meter in place.
As for wiring, I grounded it to the bolt on the frame that normally secures the wiring harness loom in place with a clip. For the positive supply, I hooked it into circuit feeding the headlight.
A quick test showed it functions fine. I like that it is out of the way, yet easily viewed whenever I have the desire.

Spark plug resistor cap
Updated: Mar 23, 2010
I recently replaced my original spark plug cap with an NGK VD05FP (8429). Has the waterproof covers. Fits and works a treat. I've a 1993 DR350. You'll want to check the specifications to make sure it works with the later spark plugs, etc. Here is a great document from NGK that'll tell you about each 
resistor cover (as they call them).
