DRZ Keeps Shutting Down - April 7, 2010, 06:05 AM

Yesterday I rode into work, and on the way home got caught in a lot of slow moving, very hot traffic. About 5 miles from home (moving decently by this time) the bike started to sputter a little bit, started losing power, and eventually turned itself off, leaving me to coast to a stop on the side of 66.

My initial thought was I ran out of gas, so I switched to reserve tank, and bike still wouldn't fire up. Switched back to normal fuel and still nothing. Turned the key off and then back on, almost started, then tried again with a little blip of the throttle and it started back up. Made it another 3 miles and the same thing happened again. Same routine, and then once more in my neighborhood. My thought at that point was that the thing just got way too hot. Finally started again after a couple minutes of just letting it sit and made it home. Parked it and let it cool down.

About 9:30 last night (5 1/2 hours later), I went out to take the bike to the gas station to fill up for the ride in today, and the same issue was happening. So now I don't think it was an overheating issue. Battery seems to be just fine, because it has no problem turning it over, just a matter of whether or not the bike will fire and keep running. When I feel it start to go, it just loses power, begins slowing down, and eventually just cuts off.

Any thoughts?

initially sounds like its an overheating issue. then again it could possibly be something electrical. you may have gotten some bad gas or there is are or water in the lines. doubt either one but its possible.the bike may not be getting enough gas, i would check your tanks for sediment or kinks in the lines.

just my 2 cents

First thing that I thought of was dirty carbs, maybe the float sticks every once in a while, which would cause no fuel to get through the carbs properly from time to time, that is if its sticking occasionally.

The reason I say its the float bowl, is because its happened to a quad that I used to ride/maintain for a friend. It would turn over fine, good spark, battery perfect, yet seemed to be getting no fuel, and it sounds like you are getting fuel in increments, so try taking it apart and just cleaning the carbs, shouldn't be to hard, and you might as well do it, its not going to hurt anything, and if it'll do anything, its going to make the bike run better with cleaner carbs

First off there is only ONE carb on this bike people!!!! Second what has been your mpg? Pull the plug and see if it is running rich or lean. Maybe the hot weather has it running weird. also pull the airfilter and check it. Bike could be starving for air. Also have you been getting gas from the same place? Maybe you got a bad batch but that has not happened in quite a while.

When I had the Husky I had the same issue, it would stall out very similar to what you described. I removed the carb and handed it over to Vondari to work his magic, he cleaned it out and did a few other things and the bike was completely fine. If you haven't cleaned out your carb I'd recommend starting there...it never hurts anyhow. As Dodge said...check your plug as well.

Good advice Dodge...blip the throttle after it starts up, if it dies then its your air fuel mixture(not enough air to match the fuel)...but definately follow his advice about checking air filter, fuel, spark, and especially the carb...

MPG has been in the 55-60mpg range. All gas thus far has been from the same station and the same octane. I will check the air filter later today and check the lines as well. Never cleaned a carb before, but I've been reading all morning long, and it seems as though most anyone that can read and has a little mechanical knowledge can handle it just fine. Sounds like my Saturday morning schedule is filling up!

Also, when it does decide to fire up and idle it seems to have no problems at all, just experiencing this problem while I'm actually moving.

Thanks for the suggestions thus far.

It takes about 15-20 seconds from the moment it starts to sputter till I cant keep it running anymore. I eventually slow down and grab the clutch to coast to a stop, as soon as I grab the clutch it usually dies.

Check your gas cap for proper venting.

Slow speed stuck in traffic + hot weather + no venting = pressurized tank. It will "flood" your float bowl and severely richen your jetting.

Jar yah beat me to it!
Gas cap

But I was thinking it could be a vacuum in the tank not filling the float bowl. Pressure in the tank or a float stuck open and it would spill gas out of the carb overflow.

Next time it happens pop your gas cap listen for a "whooosh" or the sound air passing though.
