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.

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.

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.

I just want to say that the total height of my idle adjustment/throttle stop screw is about 10mm above the bracket. This is the outer screw length (9mm) plus inner pin height (1mm). When your throttle is completely closed, does the throttle rest on the throttle stop screw, or touch it at all? It should - unlike in that picture a few pages back. I don't mean to beat a dead horse though, so onwards!

Really, the only things that should affect idle are the pilot/idle jet, idle adjustment screw, fuel/air screw, and float level.
Your pilot jet is known good.
Your fuel/air screw is probably fine.
You don't like your idle adjustment screw anymore!
So, I guess you need to pull the carb apart and check if you missed anything - any little spacers or o-rings? Check the float level?
You could take out the fuel/air screw without taking out the carb and see if the spring, washer, and o-ring are on it first...

Did you change anything else on the bike at the same time as cleaning the carb?
Do you have a tach by chance?

Thanks for the measurements mate. Here's a shot of mine. Looks pretty much the same with pin wound up as far as possible.



A bit of an update.....

Pulled the carb again and checked every jet and gave them another clean for good measure. Everything looked fine.
Gave the idle circuit a good soaking in carb cleaner spray as best I could with no compressor to blow through. Let it sit for a bit then did it again.

Then went back to the float assembly. Before setting the float height again just did a little inspection and notices the piping in the float assembly has a tiny jet in it.



Which comes out here...



Eyeballing it against the light I couldn't see through it so drowned it in carb cleaner and used a tiny dental brush to gently pry the jet. Nothing came out. Blowing through it didn't do much but eventually I thought I could see a tiny dot of light when holding it up to the light. I don't know what this circuit is for or whether it's relevent but figured it has to do something.

Then fit the float assembly back and checked the float height. Float height looked OK from what I understand but when holding the carb the right way up so the float is on the bottom I lifted the float with my finger to see if it moved freely. It went up fine but when lowering the float the jet stayed in the hole until the tab touches the wire loop. Then it drops with a tick. Tried it a few more times and realised it was sticking in the hole. Pulled the jet out and saw a tiny bit of varnish on one of the four posts around the jet. Cleaned that off and tried again. Now the jet morves freely. That must be some pretty fine tolerance there.

Put the carb back together and reinstalled in the bike.
Now it starts easier. Choke still prevents it from starting. Warmed it up a bit then let the throttle drop. Stalled.
Started it again and warmed it up for a few more mins. Let it drop. SUCCESS

It's idling by itself, sitting on the throttle stop. I'm guessing it was the jet not dropping freely that was the main issue.

Thanks tons for all your input fellas. Legends, all of ya

Here's a little vid. Can anyone guestimate whether that idle sounds about right?

do a pinesol clean on the carb. way back when, i thought my carb was clean until i did and was amazed how much dirt came out. http://advrider.com/forums/showthread.php?t=560117

i now also run a small pour of Lucas fuel treatment through all my full tanks of gas. after another year and 1/2 i pulled my carb to look at it clean everywhere. did a precautionary pinsol clean and i had only tiny amount of dirt. it's oil based (not a distillate) so it's not harsh. my bike is happier when i use it. goes in everything i have with a motor. http://www.lucasoil.com/products/dis...catid=2&iid=26
