A glowing pipe while idling is completely normal for a DR650. It has been discussed here many times. if you tune it so rich that the pipe doesn't glow the bike won't run either. Trying to tune the idle mixture with the main jet and needle position will just get you lost in your tuning setup. You still have the stock exhaust so put the 145 main jet back in. Running the 150 main will just make your bike slower.

Idle is controlled by the idle mixture screw and idle speed screw.
Mid-range throttle response, steady speed cruising and 'low rpm wide open throttle' is controlled by the clip position.
Wide open throttle, high rpm operation is controlled by the main jet size.

They all do that. It aids in night-time conspicuity .

Oh thank you. That put my mind at ease. Then I will install back the 145 tomorrow and see how it goes with the rest of the settings.

Errr I'd not be so certain as to the local skills at fixing stuff from raw products, it may well be that locals have the skills to perform a repair quicker and certainly cheaper than a slow expensive (import duties and delays?) delivery. As to the availability of the wire leave that to the locals, they know more about it than us?


Consider that imported goods may be very expensive and that labour rates may be low. A replacement alternator for a car or truck may be a year or twos labour charges - so repairing it is desirable. The people repairing alternators may also do coils too...

The wire gauge of the stator coils would make them more able to withstand the stress. Buy the time the stator coils failed you could expect say two source coil failures? All guess work based on theory. So not worth much in the real world where practice and results are far more important.

Correspondences on CV carbs:

Low rpm all throttle positions: float height, needle base diameter, emulsion tube outlet size
WOT operation overall: main jet
WOT operation between HP peak and red line: main air corrector
WOT operation below red line: jet needle shape
1/4 throttle opening: jet needle clip position
1/8 throttle opening: pilot jet size
1/16 throttle opening: pilot jet size
idle: mixture screw adjustment

Note that tuning should always be done from the top down, although the idle mixture screw should be adjusted at each change.

I remember the days of texting with a number pad... annoying for sure.

I once got so furious with my cell phone provider's customer service person (a customer service complaint), that at the end of the phone call, I took my Motorola flip-phone and put it under the rear tire of my SV650 and ran it over

A few days later, I had a shiny new iPhone with a new cell company. Within a year, I ditched the iPhone and got a Samsung Galaxy with Android. Much better.

It would text also, but I refuse to type with a number pad. (no qwerty)

I'd love to throw it in the woods and only be able to be contacted at home, but it's invaluable when trail riding.

i see you are letting go of your DR are you selling any parts / separately ? If you are send a list of parts / cost. I am in the market for some DR 650 upgrades without blowing my budget.

Nice summary, I'm on the verge of some fiddling.

Speak for yourself . I doubt the locals in central Africa know more about winding coils than I do . The wire not only has to be the correct gauge but has to be coated with insulation that will not break down in hot oil. If Jay was stuck in a country that has some manufacturing base he might be able to source some wire that would work. The chances of some Kibondo local having wire that would make a reliable repair are remote.

The stator I have on my work stand looks to have the same gauge wire in both the charging coils and source coil.

My opinion is trying to rewind it would be a last resort emergency option. It sounds like there is some chance that unplugging the stator will let it run long enough to get the bike to a place that has more resources than Kibondo or at least somewhere that a stator could be shipped to.

glad

I put my magnet in at 3,400 miles and only saw light dusting at 4,480. First oil change at 500 miles.

Does this like normal wear for a DR with 15,500 miles?

For the fast idle problem ... I would ensure your throttle cables are not hanging up. Very common. Routing should be perfect. Check them. Even if twist grip is shut ... you could still have the throttle slide hanging up a bit.

If you can't solve this (carb probs) ... I'd buy a nice BST Carb off someone here ... preferably a nice virginal one that hasn't been "Tuned".

Good luck Bob and good work getting her running! You are almost there!

That picture reveals many times what my motor shows at an oil change interval. I always use Mobile 1 15/50 in my DR650

Hi Refokus,

Perhaps I'm being optimistic. However, I'm pricing the bike taking into consideration the modifications and the market price of a similar bike in Paraguay, Argentina and Brazil, the three countries to which I'm closest at the moment. In Paraguay a new DR650 runs about US$9,000, in Argentina about $10,000 and in Brazil probably $13,000. So even a one year old bike with 24,000 miles is within reason. On MercardoLibre, the ebay of Latin America, there are a few 1999 DR650s with between 40-60,000km selling for US$4-5,000. In all of these countries it is hard to find or import quality modifications. The import duties often double the price of the item. While this bike does have 24,000 miles, it has been maintained tightly. And it is running perfectly.

Thanks for the feedback. If I am unable to sell her, I'll just bring her home with me.

Troy

Hey Jim,

Thanks for the question. At the moment, I'm trying to sell the complete bike. If I do sell the bike complete, I will have some of the original stock parts that I will sell once I return home. The original parts are in new condition and are in storage at the moment. If I am unable to sell my bike, I will bring her back home with me. Then I may rebuild her as a stock bike. I would then sell all the goodies. I'd be sure to post on this thread.

Thanks for the inquiry,

Troy

I hope everyone here takes time to check out your report!

Cheers!
Cheers Grifter. Thanks for following. It's been a ride.
