Iam thinking of getting the jet kit but might get both?
It's about 100 US dollards plus shipping. [from Australia, might cost as much to ship it there and back though]

Just wondering if it's worth getting the stock pipe converted or getting an after market that is lighter and maybe better?

What are your thoughts?

Is there a good aftermarket can that works with his jetting kit?

Thanks for your time and help

kind regards

I also replaced a loud Cobra silencer with the stock/modded Kientech silencer and jet kit. While I cant say that it was a significant improvement in power over stock, I will say that the engine is more responsive to the throttle with no stumble or flat spots and no "popping" on closed throttle deceleration. It seems much more crisp. I'm very happy with the sound as well.

Thanks for the replies all

DTP any suggestions on an aftermarket replacement? I did a quick search and am unable to find any variety.

This may have been the problem, or part of it anyway. If you look in the plug boot where the wire went, you'll see a pointed screw. The wire threads onto this; if it was loose it could cause intermittent spark and bad idle. If it's nasty, you'll want to trim the wire back a bit and re-install by twisting the boot onto the wire. (note how the core sticks out and is bent around the outer sheath) I hope that fixes it; it must have vibrated loose.

The resistor is accessed from the spark plug end of the boot, not the wire end. Look for the flat head slotted screw down in the boot.

Mate I have tried about everything out there as far as after market mufflers and found they were all obnoxiously loud with massive amounts of backfiring on decel freaking annoying for me and anyone riding with me along with pissing off general public .

I went with Jesse's modded one and have been very happy , nice tone with it.

Ill keep ya updated, thanks for the help.

To answer your question my experience with carbs is on the low end. I have had a BST 40 all the way apart but never been deep into a pumper carb.

PS any one have prefence with the DPR9 over the DPR8 spark plug or visa versa?
Hi frdbronco8,

If you are looking for a new spark plug cap, I've had good luck with this one.

Hi Andrew,

My 1993 DR350 dirt model came with a SuperTrapp that was way too loud for my taste. I wanted something a lot quieter. I bought a modded muffler from Jesse and I'm very pleased with it. It isn't silent, but it is much quieter. As for performance, I couldn't tell any difference between it and the SuperTrapp (seat-of-the-pants dyno).

I started off with Jesse's recommended jets, but they were too big for my DR350 where I ride (2250 feet and up, up, up from there). I'm back down a lot closer to stock (37.5 idle, 132.5 main) and it is running great (only other mod I inherited is the air box).

I've never experienced a stock muffler, so I can't provide any comparison data for you there.

Hope this helps!

Regards,

Gregory Bender

Yeah the switch I bought was this one here. Only $20 and it works. My local Cycle Gear had about three or four in stock.

WHY are all the deals on the wrong side of the country!

Guy lists this bike as a dual-sport, but the headlight looks like the offroad version to me:

I would assume that is not street legal. No mention of title or any apparent street equipment.

Its a dirt model, note the lack of a starter motor and presence of a kicker :)

He may have gotten a plate for it though. Great deal too.

Mine's a street model and it has a kicker with no electric starter.....as do other pre-1994 DR350S's.

The add says 1998, no reason to think that's wrong, esp as its got forks that can't be older than 1997, the frame color was only used in later years, it lacks turn signal mounts on the rear fender support, etc. Unless someone has swapped a ton of parts around its a 97-99 dirt model.

Newb question - when I do an oil and filter change on my DR is it better to warm the motor up before I drain it? That's what I do on my trucks but they have much more oil in them so I'm not sure if it matters on this bike, it's my first 4-stroke.
