Stuck in Zacatecas, Mexico

[scooteraug02]

Did you ever change the spark plug.

I remember on my 2 stroke bikes when the plug went bad it would start and idle but die when the throttle was opened. Put a new plug in and it would run like a champ. I always thought that was weird to start and idle fine but die with added throttle.

Stepping back and looking at the overall situation. You said it wasn't sudden, started acting up. Being in Mexico I would think bad fuel or dirty fuel clogging the carb or tank. Did you ever try to start it with the fuel cap off or opened. A clogged gas cap vent can cause fuel starvation.

Of all things mentioned ... the pick-up coil goes to the top of my list. If you read the 11 million post BIG DR650 thread ... you'll see that over time there have been several failed pick-up coils (also called "ignitor or Pulse coil). Not many, but a few. One was on Big Al's bike which failed somewhere in Cent. America. The local mechanics borrowed a PU coil from a car and fit it in .... IT WORKED!

You're correct .. The PU Coil is part of the Stator. It's rare but there have been a few over the years.

I don't believe the carb is the issue. (unless it's been buggered up by someone trying to "fix" it! )

We've never seen a Main coil go bad on a DR650. There have been a few Stators gone bad but most times it's misdiagnosed and turns out to only be the Pick-up coil.

One or two bad CDI boxes too ... but once again ... very rare. On the road I carry a spare Stator.

Best of luck !

Sorta, note the red circle.

Thanks for your suggestions. We switched out the fuel, cleaned the petcock filters, and installed new plugs. And we confirmed that the tank was venting. But again, it didn't start.

Depends on the technology used, but yes, it'll be near the stator.

Ok, you made it back to Mex. We're all anxiously waiting to hear the final diagnosis

Dave, My three flights down were without a glitch...couldn't have been better. I'm unpacked and have my kit ready to meet the tech at 9am. It's the moment of truth...I'll report back later in the day! Jim

You only need 4 things for an engine to run; compression, fuel, ignition and timing. So, if you've got compression and your plug jumps a nice spark gap and your timing marks all line up and valves seem to open/shut in step with a 4 cycle ... then ?

Good luck, dude!

Although my bike still isn't running, the problem is identified. To save me the work of explaining things in two places, please check out my pics and explanation on my RR...http://advrider.com/forums/showthrea...8#post20439568

Again, my thanks go out to all of you for your help and support!

Too bad you didn't mention the fact you'd swapped out the stock Stator early on. You could have saved A LOT of time and money. Any owner installed Mod always goes TOP OF THE LIST for where the problem started.

But I also blame the Mexican techs for not finding this in the first hour of work. Hate to say it ... but I feel they strung you along ... WAKE UP!
This sort of fault is a novice mechanic diagnostics 101 exercise. I know your guys know more than they are letting on. Oh well, live and learn!

BtW, aftermarket Stators are famous for failure. Many many KLR guys have gone with aftermarket stators to gain more output. Many end in failures. It's all over the KLR boards, has been for years.

If you feel you need more elec. output you should have come over to the BIG DR650 thread. Lots of guys there with plenty of helpful tips on how to set up your bike to get by with the DR's measly 200 Watt output.

Many good mods and upgrades to get by and still have power for elec. jackets, grips and running GPS and such. No problemo. Hope you can still enjoy the rest of your trip! I'll check out your report ... and please ... from now on ask on the BIG DR thread if you have questions. A wealth of knowledge and even some direct support from Pros over there.

On our SV portal site there have been numerous occasions where the magnets in the rotor have came loose and pretty much given the same issues you had. Glad you figured it out. Life goes on.

Keep on ridin'...

So my issue isn't an exception. Other than what's in the manual, are there any instructions out there for a secure installation?

Your rotor is designed differently from the SV's. Ours does NOT have the metal ring on the inside. Some people have used JB weld to epoxy them back into place.
