Electrical Issues (Solved)

My DR650 has had odd electrical problems for over a year. I replaced the battery in early 2011, and by that Fall, it was dying. I figured the battery wasn't very good, so I replaced it again with a new Yuasa this time. In early Feb, my Battery Bug showed things weren't charging well. I ordered a new (aftermarket) regulator from ProCycle and installed it. Things seemed better, but the Yuasa wasn't doing well now either.

A few months ago, I noticed again that things weren't charging well. I got back from a ride to find my battery voltage at 12.0 and the Battery Bug beeping away. I swapped the old (new) battery back in since it seemed to be holding a charge. I was glad that I saved it. I decided it was probably the stator, so I ordered one from ProCycle. Since the bike is a 1996, it made sense. Might as well replace it, since I can get the 250 watt version.

Installed, and all was well again.

Then last Friday I rode from NW Oregon to Reno for the weekend. I noticed during the ride that it wasn't charging again. I watched my battery voltage drop lower and lower. Then after a gas stop, it started charging again somewhat. Phew.

Got to Reno, then tore into the bike. What did I find? One of the wires on the regulator connector had come loose!! It appears that it was never properly crimped to the connector. A trip to the auto parts store and I was able to get a new crimp-on connector to replace the bad one in the regulator connector. Now it's charging very well! And the battery I thought was dying (the first new one -- an EXT9) is doing very well.

So in retrospect, I don't think the stator was bad. I'm not upset about it, since I got the higher-output version. Now I can run my heated vest this winter without having to give up my handwarmers. :)

So... if you have weird charging problems, check those wires!

Just finished installing a Trail Tech Vapor on my DR650. This one has the heat sensor under the spark plug. I'm wondering if anyone is using this setup and what heat readings I could expect from that sensor location. I'm using CR9 plugs. You might also let me know what your RPM is at a given speed with stock gearing. I would like to compare the tach feature for accuracy.

Thanks...

I have this setup. My temps vary from the 280's up to the 350's depending on ambient temp and how hard I'm working the bike. I'm running CR10E plugs in mine, as I believe this is the stock plug.

My gearing is close to stock.. I'm +1 in back compared to stock (16/46), but I'm turning 5000 RPM at 68 mph with a properly-calibrated Vapor.

That's what I see also.

Thanks. Funny I also am running 1 tooth more in the back. CR 10 plugs are stock but the manual options the CR9 as suitable also. I am going back to 10's in a week or so. I live at 3500 feet and often see 7,8,9,000 which is why I run the 9's.

A few thousand miles ago I tried installing the Pro Cycle jet kit as stock there was some lean surge. No way in hell would the bike run after the airbox was cut per instructions, regardless of where I put the needle it was way too lean. Used duct tape to slowly cover the hole while moving the needle until I had a hole slightly larger than the snorkel hole and the needle clip on 3rd from top. Ran great, got 50+mpg for many miles, but the duct tape of course kept coming loose. Had a little of what felt like lean surge, so I marked the air box and replaced the duct tape with a riveted and siliconed piece of tank bag stiffener.
Now the bike starts and idle just fine, takes full throttle on the stock main jet just fine, but if I try to give it a bunch of throttle in the mid range it falls on its face.
It will rev to red line on full throttle.
When I let off full throttle to about 3/4s it dies then catches and continues to accelerate.
If I ease the throttle open it pulls ok.
It does it whether fuel tap is on regular or reserve.
Starts and idles great, responds to idle mixture screw changes.
Will cruise at a steady 65 to 70 just fine.
I've gone from full up to full down on the needle clip - no real difference other than a very very slight improvement at full rich.
Slide has been drilled for a few thousand miles.
Manifold screws are tight.
Petcock vacuum plug is in place and in good condition.
Air cleaner is clean.
Fuel filter is clear.
Little o-ring under the cap is in place and looks fine.
No smell of unburnt fuel.
Valve adjustment is spot on.
Plugs are only about 1K miles old.
I just can't open the throttle fast unless I go to FULL throttle. Anything less than full throttle it hesitates, catches, then craps out again..
Your current running situation sounds like exactly what would be expected if running the DJ/Procycle needle with an uncut air box. It runs well on the idle curcuit and WFO with the small main jet but is way too rich on the needle. You will never get that needle to work properly without opening the airbox.

Hey folks-selling a set of 2009 plastics with an 09 matching tank. Shameless plug.

Hi,
Been reading here and I keep seeing the NSU screw. Where is it? And why does it come loose? I looking to buy a late Model DR soon and just doing some reading to see what I'm getting into coming from the KLR world.

It's the DR's version of the Doohickey I guess. It's not bad though. It's the Neutral Sending Unit. Open the clutch-side of the motor, pull the clutch out, and remove the two screws holding the NSU in place (they're probably loose)... apply threadlock and reinstall snugly. Done.

'Course this means you have to drain your oil first, and probably need a new gasket for that side of the motor, but it really is an easy fix.

Don't let the length of this post scare you, just different guys showing their solution.

Where are the DR650 videos or are you just spamming?
