Here is the followup. I used the 16 tooth to commute from Parker to Broomfied which is a distance of 44 miles. By using the 16 tooth, the motor was in the peak of the powerband I believe at 65-75mph vs being on the downhill side of power at those speeds. The speed limit out here is 55-75. When heading home, I took a less traveled route and was able to basically hold the throttle wide open for about 30 miles. The bike peaked out at around 80mph with no wind and 85mph downhill. I found that if the kickstand starts to droop, the bike will die. Ugg...that is getting fixed.

MPG for the day riding it mostly 3/4 to full throttle was 50mpg. Twice my acccord when running A/C. Still, commuting sucks on a bike but it was fun to do it for a day. Man it was hot.

Corbin seat made it easy on the tush.


Here is a pic:
Ready to roll


Parked with the cruisers. 99 degrees.


Moved the backpack to may handy dandy rack from Shearboy. Thanks!

After much deliberating I finally ordered a Seat Concepts seat and an Acerbis tank for my 99 DR350SE, hopefully it will provide the fuel and the comfort for some longer rides and light touring.

Wow, that mileage is pretty bad for a DR, isn't it? I've been getting about 70mpg, but mostly dirt road stuff with a few pavement sections. Riding faster than 60mph has been kind of dicey due to cross winds, but the rpms are reasonable with my 14/43 gearing (1990 model).

I got 74mpg out of the bike on the first 100 miles of this ride last Sunday.

Hi _CJ,

Out of curiosity, which carburetor do you have? The CV or Pumper carb?

My 1993 DR350 (dirt model) with the pumper carb will yield me right around 50 MPG. I weigh 220 pounds.

Regards,

Gregory Bender

It's a street model with a CV carb, and I'm tipping the scales at about 220 as well.

Uh, no. The star hides my workplace name.

I believe it's a factory 41 rear. The bike is mostly stock with all original parts being it only has 4500 miles.

Oh, it's bad and I imagine due to the strong winds and full throttle runs for upwards of 30 minutes at 7.5-8.5RPMS....it will suck fuel just a bit heavier.


That was my plan however to get the "worst case scenario".

I think there is a pretty big difference in expected MPG performance between the CV and pumper carburetors. I'm not saying it isn't possible, but I've not heard of anyone getting 70 with a pumper carb. On the contrary, I hear regular reports of people getting 70 MPG with the CV carb.

I love my pumper carb. But I've got a long trip coming up where I am going to be in some pretty remote portions of the West. I am wanting longer range without carrying fuel in excess of what my Clarke tank holds. So, I'm in the midst of fitting a CV carb to see what I can do about mileage. I would be thrilled to achieve 60 MPG (a 10 MPG increase over my pumper carb). 70 MPG? I doubt I would believe it if it happened to me :> :> :>

We'll see....

Regards,

Gregory Bender

Greg, if you keep the RPMS down with stock jetting and a CV carb, these little motors as you know sip gas. My idle jet is too large and I can get 70 just putting around and keeping my top speed to 55.

Gotta give you credit for taking that bike out in Denver metro traffic. Doubt I would have the nerve to spin my engine that hard for that long, let alone contend with the traffic up there while doing it.

Meh, I figure the little motor could easily handle 8K. The motors tank right around 50k anyway...so it's not like I am going to see 150K out of this motor so might as well ride it like I stole it.

Just talked to this guy on Craigslist, he has a 1992 DR350, kick only. He claims one of the oil passages got clogged and starved the head. At a minimum one of the cams is scarred pretty bad, and there's no compression. He said he'd be happy with $200 for it. Worth a shot? I don't really need another bike at all, but a DR350 would be kinda cool to have around. My XR650R is an excellent bike, but I wouldn't be against having a smaller dual sport.

Edit- Any guesses as to what all would be needed for repair? New head/cylinder/little stuff is probably more than the bike's worth

Good used heads are tough to find and new ones are expensive. $200 is fair if you plan to part it out *OR* if you know a good machinist who can fix the head.
