I dont think I ride that hard (in the street). High 30's with Mefo DS tires. I did notice a 4mpg jump when I went from Mefo's to Pirelli Scorpion Trail street slicks. On the freeway, 60-70mph, avg. I do have a windscreen on the front, maybe that's doing it.

A solid piece of alum is cut to the size of the plate for support.

That's weird: I smudged my lisc plate in Smugmug and now it's bigger than the second pic??



How I recessed the plate light. You can see the alum piece at the far left of the pic, really dirty.
I like this. So you just modified the stock mud flap to what you have there? And that is a drz250 taillight?

So.... um.... what happens if after you remove the upper chain roller.... you thread the set screw in too much... and it drops into the frame.

Maybe.............Procycle calls it a DR250, Kientec calls it a DRZ250. If you buy from either of those, you'll get the correct light. If you want to order from your local dealer, I don't remember which I ordered 8 years ago. BikeBandit is being difficult or I'd give you a better answer.

I made a mid-pipe back then, and it was really ugly; notch, bend, weld, notch, bend, weld; etc. So very glad the side cover hid it.

Question IMS Petcocks & reserve

I know the IMS petcocks don't have a great reputation, but are they really POS? My buddy and I were both running our DRs on a long route in Death Valley and carrying an extra gallon of fuel each so we could run our IMS tanks until hitting reserve and then down to empty to find out what our ranges were.

Well we both got a surprise when neither of our bikes would start when we first ran out of fuel and switched to reserve. We could see the fuel in the tank right at the top level of the petcock. We ended up having to add our spare fuel to continue the ride and so we didn't learn the real range of our bikes with IMS tanks.

Any ideas on how to fix short of replacing the IMS petcock? Is there a separate filter on the petcock for reserve that might be clogged?

If we hadn't been carrying spare fuel, could we have modified the IMS petcock in the field to get us back to camp?

This happens regularly, I think it's the up-hill loop in the fuel line, something I learned from my snowmobile. fwiw: I still have my stock tank.

Usual routing:



Guys have been rotating the carb inlet 90* to the left: 9:00 o'clock. I think Tim came up with a better idea:

I guess it rattles around in the frame.
I know when I do mine, (with a set screw) i'll centre punch the very top thread on the side, with the hex key in the hole, some thread sealer, and screw it in. That'll stop it from falling in and give it a little bite. No bolt heads to worry about.

+1
Or, like myself: Being an airplane guy. . .light is better. So, a dab of ATV on a fingertip. I'm sure i get maybe .00000000000002 more mpg.

edit: yeah yeah yeah. . . .ok: Smear the atv from finger to hole. Shhhheeeese.

High 30's? Your thumbnail/website states the average is about 45. I ride mostly street commuting to work and back and I also have a windscreen (screens for bikes) but it may look like you have a bit more weight strapped to yours than I do mine, plus the fuel tank and whatnot.
I'm running the Shinko 705's, keep mine luggage free when possible and i only weigh around 165, so that may be the difference between the two of us.
I guess my point was even after I jetted it, added an aftermarket exhaust and re-jetted. I got a lot more fun-factor and barely lost any mpg's for it, but an avg. of 45 ain't too bad either.

Mine ran out on the highway the other day, was able to reach down and switch to reserve, bike sputtered a bit then came back to life. I have a TM40 carb though, maybe that makes a difference.

The screen for the fuel straw (on position) and for reserve is one and the same. You can use a flashlight to look in your tank and see it. I doubt it's clogged, try running your bike on reserve with a full tank

Its jumped from 37-39 (Mefo's) to 44-48 with the Scorpion AT's. Thats a pretty big jump. Im sure once I throw the D606's on in the next month or so I'll drop a few MPG again. Oh well, this bike still rawks
