I got home and it felt like the idle was a bit low, so i turned the knob in a little bit it while sitting on the bike. I smelled gas, but thought nothing of it. Got off the bike while it was running, and saw fuel spilling out of the vent hose. I followed the vent hose up, and it was the one under the Idle adjustment (see pic). What is this from? When I shut the petcock off, the fuel stops flowing from the vent hose.

I would like some advice before I start pulling the carb apart, Thanks guys..
someone correct me if Im wrong but I think that means the float is set way too high allowing the bowl to overfill.

I can't remember if the hose in the picture goes to the bowl drain (probably not) or up via a internal tube to a overflow but.........

My TM40 has done this a few times over the last few years for no apparent reason.
Once was coming into Top Springs (dirt road in the middle of nowhere) and noticed it exiting fuel from a hose.
Stripped the carb but found no obvious signs of the fuel seat not seating.

Another time I came out of a large hardware store to find the bike sitting over a '3 foot puddle of fuel.

Could the float stick once in a blue moon is still ??????????
I never leave the fuel taps on,if it was to run down the inlet tract that might risk hydraulic ing the engine also.

Mine did this as well, I removed the carb to adjusted the float and has never occurred again. Pretty simple to do, I was a newb and got it on my first try. Maybe it was just beginners luck

It also stripes oil off the cylinder walls accelerating wear on the piston rings and cylinder.

lol yeah that is pretty lucky. There are lots of techniques for setting the bowl height, I've never done it though.

More likely a little bit of dirt or debris is stuck in the float valve.

stock foot pegs for DR

Does anyone have a stock close up photo of their stock DR foot pegs? Took mine apart, painted them. Kind of forgot exactly how they sit on the bike. I think I have it, but I am losing my mind thinking about it.
Mahalo,

Mahalo,
Don't have a pic on the bike but here is a diagram that may help

Thanks for all the quick replies, I'm going to keep an eye on it. Since I don't have a fuel filter, I think it time to get one. If the problem persists, I'll get in there to reset the float height.

Probably a bit of crud in the needle jet in the float bowl. I would drain the float bowl, re-fill, drain again. Hopefully this will clear any crud out.

If engine is dying at idle ... try setting the fuel/air pilot screw, then re-set idle.
1. Set idle very low after bike is fully warmed.
2. Using Pilot fuel-air screw ... adjust for smooth and highest idle ... then adjust IN (lean) just a hair.
3. Now set Idle to desired RPM (DR650 seems to like around 1300 to 1400)

Spring rate

I purchased a 08 DR 650 the other day. Its stock except for some small dirtbagz side bags and a big parabellum windscreen ( soon to be in the flea market). I want to install stiffer springs front and rear. On the race tech website if I search for 225 lbs, it gives me rates of 8.3 rear and .70 fork. Does that seem correct? Seems like it will be stiff....any help would be appreciated ... thanks

Call Jesse at Kientech. He'll ask your weight and details, and recommend the correct springs. Good guy and tell him Steve from Hamilton sent you.

I'm 227# nekkid. I went with the Race Tech rebuild rear shock kit with 8.6 rear spring - love it! I tried Iniminators with .05 springs in the front. Worked really well loaded for touring on rough pavement. Didn't work for me without the touring load on pavement and didn't work on rocky off road. Too stiff. I've since gone back to stock springs and Intiminators. That combo works well on the pavement and rough rocky offroad. The .05 may work for high speed jumps,etc., but not in my real world.
YMMV

Man....should start a weight loss thread.....

I'm WELL north of 300 with all the gear and the suspension upgrade is next on the list after the seat. What can I do to my stock suspension right now to prevent it from bottoming out terribly and have it handle somewhat decently on the road? I fully realise that I won't get any high performance out of the stock suspension but some tips for the mean time would be greatly appreciated.....
