And when I filled up, it only took 10 liters to fill my IMS tank so it was still half full.

So I think the next step is to check out the fuel tap.
...and the venting in the gas cap. Do you have the locking cap? The vent gets plugged in mine which at some point makes a vacuum in the tank and the float bowl won't fill fast enough to keep the motor happy.

(Procycle advises taking the cap apart and poking a hole with an icepick in the rubber piece.)

If you make the hole too big you might have a small amount of fuel spillage in a tipover.

That book is written by the people who built the bike and the valves and valve seats,at least if its a factory manual.
On almost all newer 4 strokes the valves arent lapped in they are simply installed and checked for seal. If the old valve is worn down to a sharp edge then you gotta see what shape the valve seat is in.

Old school mechanics will want to lap the valves regardless of what the maker of said valves says. It wont hurt but they dont need it.
They are so hard not much will happen lapping them.
I put new valves in my 01 DRZe a while ago,the old ones still looked good,new valves were 26.00 each so for the heck of it new ones were installed,they sealed perfect with no lapping.

DRZ/DR valves are simple steel valves,on newer tricker 4 strokes they have hard coatings/titanium valves maybe that cost 100's of dollars.
1 or two adjustments and they are toast,the hard coating is worn through and its time to replace them.

DR's valves last a long time and are simple good quality valves.

Don't let it sit all winter without starting it? In all seriousness, I use fuel stabilizer (or race gas) and simply start the bike every second or third weekend thru the winter. Let it run for 5-10 minutes (to generate some temperature) and then shut it off. I've never had any trouble come Spring.

Your issue might be a partially clogged pilot jet.

Just stopping in to say hello. Name is Andy, I just bought a 2005 DR650 and been surfing through this thread, picking up tips and tricks. I have had KLR 250's prior to this DR. I have only rode about 1/4 mile due to weather and waiting on gasket to fix my screwup, but that 1/4 mile was awesome! Look forward to getting to know all of you.

Welcome Andy. When you click on thumpers at the top there is a stick: bike specific, click on that and then go to dr650. Tons on info.

I had the locking cap until last Fall when the gasket started leaking, so I put a standard IMS cap on it. The tap flows at a verified 500 ml per 15 seconds, so it's not the tap itself at fault. I'm thinking it could possibly be the fuel line being constricted since the carb still has the inlet pipe going straight up, so the line is fairly short from the Pingel tap to the carb, and has a nasty twist which could be restricting the flow.

I'm going to try to make that line up better but the last time I attempted to turn the inlet pipe, it failed to move no matter what I tried.

Did you instal an inline fuel filter between the Pingel and the inlet pipe? Might want to check to see if it needs replacing.

Would you mind posting a photo of that nasty twist, just for the curious? Be sure to understand, the Monday morning quarterbacks are probably going to question your routing; even though you had no choice in the alignment.

My Acerbis 5.3 passed the first 'run it until completely empty' test. But adding the gallon I had, wouldn't flow thru(sic) the uphill bend. I had trouble getting it restarted. This was my first exposure to the situation, next time I'll use the fuel enrichment immediately (hi Derek ) (it was completely warmed up and I thought it would fire right up). Yes, the petcock was set to PRI while I put my helmet and gloves back on to refill the float bowl.

I occasionally have the exact same symptoms on my '05 DR with an IMS tank. I have the old, original IMS petcock that has the fuel outlet pointed forward instead of back toward the carb. Because of this, I run the fuel line upward and then back to the carb, so some of the fuel line runs above both the petcock outlet and carb inlet. After sitting for a while with the petcock off, sometimes an air "bubble" will develop in the fuel line and the weight of the gas above the petcock intake is not heavy enough to push out the air "bubble" and there is not enough gas in the line to syphon gas through the fuel line into the carb. The bubble could be from fuel boiling after shutting down the bike when it it very hot or maybe even a leaking float valve or maybe just from a lot of time? When that happens and I start the bike, it will run long enough to drain whatever is in the fuel bowl and then stumble like it is running out of gas, just like you are experiencing. When this happens, I just hold the fuel line down below the petcock and carb for a couple seconds to make sure the fuel line completely fills with gas and it works perfectly again until I let the bike sit unused for too long. This only happens a couple times a year, so it is not a big enough problem for me to buy a new petcock and correctly route the fuel line. So, check to see if the fuel line is routed above the petcock outlet and carb inlet. If so, that may be your problem...

One of these years I'll replace that silly IMS petcock with one that points the right way and fix it for good, but at least I know what happens if the engine ever starts sputtering and can fix it in 10 seconds...

Is the skid plate made for the DR, or another bike? Can you post pics of both sides?

At first I thought perhaps the steering head bearings might be loose but I don't think that is it. If I put the front wheel against the wall and push up and down the fork will stroke nice and quiet. It seems like the noise is coming from slight front caliper movement and maybe I just never noticed before. Just curious if any others notice this sound. Really appreciate any assistance with this so I can stop pulling things apart trying to find it. Thanks.
Hey JB650, chances are good its the front rotor thats knocking on you. the dr650 has a 2 peice front rotor and the rivets that join the inner and out plates wear just slightly and youll feel the knock/play when you grab the brakes. your in no danger unless its really bad its just annoying.

It's not pretty, but this is what I put on it this afternoon. Some clear line which loops around and back to the carb. I have the line tied to the fuel tap so it doesn't melt on the engine. This is more of an experiment than a finished setup. I hate looped lines, but I couldn't see any other way to do it right now. For the moment, there's no filter in the line, aside from the one on the Pingle tap inlet.

I rode about 30 km and the bike didn't hiccup even once, so that's a good sign.

I also put new spark plugs in and blew all the passageways out of the carb so it's hard to tell which change is responsible.

Thanks for the photo.

You might notice an air bubble in the high spot but that doesn't mean fuel won't flow. I used clear filters on my dirt bikes (long ago), and they always had an air bubble. It made me knutz.

It looks like the IMS petcock is about 1-1/2" farther back than the Acerbis. Kudos for experimenting. My retirement buddy will starve to death before trying anything new or different. Narrow minded old fuddy. That's why I asked for the pic, always looking for new ideas, whether I use them or not.
