ER70S-2, TrophyHunter, Good to hear from both of you. Happy Birthday. The DR 650 Thread is my first read of the day. This the time difference beween the USA and The Philippines I read in the morning what you guys wrote yesterday.

The only thing Malcom Smith and I have in common is age and our love of motorcycles. I did get to ride with him in the
So Cal desert once about 1965. Well, I saw him before we started and after we finished, but that was it.

About riding alone, never a good idea, and I would never advise anyone to do it, but, I enjoy it very much, and will probably continue to do it. A fellow at the motel where I was when hearing my story, said, "If you hadn't been able to walk out, they would have never found you." I said sure they would have, but, it would probably been by deer hunters in the fall.

The Philippines has some great motorcycle riding here. If I was younger I would have a motorcycle rental business and promote it. If you get a chance look in the Reginal Thread under Asia. Some great ride report on The Philippines.

All of you guys keep writing the good stuff on the DR 650 to keep an old guy entertained.

Inexpensive. Lighter than stock. Looks nice. More durable than FMF Q. Flows well. Needs to be re-packed.

LOUD AS ALL HELL.

My T63's are Czech made. I've ridden on serious Volcanic material before ... very hard on tires for sure. Like riding on a Corral reef.

I would be happy with 3500 miles out of my T63 rear ... hope I get it.

I just created a post on my blog about how I transformed my DR650 into a DR650 adventure motorcycle for a year of riding around South America. It includes all the modifications and costs. I thought some of you might be interested. She has been a great bike...and sadly she is for sale.

OK so 1-1/4 is known to be too lean. Check. Will try adding another 1/8

Idle screw/throttle stop is currently wound up as far as possible but still not enough to allow the bike to idle. Idle jet is clean & brand new. Idle circuit?

Thanks!

Hey Greystoke,

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?

1-1/4 turns might be too lean on some bikes but not so on others. If all bikes and their carburetors were exactly the same there would be no need to have an adjustment in the idle circuit.

I have the SuperTrapp IDS II It has a variable baffle system. The fewer plates you have in it, the quieter (and more restrictive) it becomes. I always take my stock silencer with me to any event, in case the sound meter say NYET!.

As a matter of fact, I have put the stock silencer back on and had it there for over a year now. I just like it quiet. I get more noise from the modified airbox and the tires than from the pipe.

I wish there was a light silencer like the SuperTrapp (it's an 8 lb difference from stock) that was quiet and flowed nice.

BTW: There is a smartphone app that makes your phone a sound meter. I know that the sound tests here are taken at 20" away from the pipe at a 45deg angle and about 1/3 throttle.

Troy!! Congrats on a great tour!! A few of us here have followed your ride from the start. Best of luck with the sale ... probably a local will end up buying your bike. Maybe contact the local riding clubs there.

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

Cheers!

Hi,

Can anybody please tell me if there should be any hose attached to the highlighed port on the stock carb?


I just noticed today that this port is not connected with anything in my case. I guess it's a port for ventilation purposes, an I wonder if a hose is missing on my bike.

FWIW, those sound meter apps for smart phones are pure garbage. Just for fun last year, a friend and I tested 3 different sound meter apps on each of 3 different smart phones. The results varied a great deal between each app, and also between each phone. Hard to trust any of them to even provide a vague idea of the actual sound level. A $39 sound meter would be a million times more accurate.

Hey guys, I'm stuck on this electrical issue. I got the spare CDI from South Africa today. It's continuity matched my current CDI with terminal 9 also reading much higher values than stated in the manual. Anyway, I put it in the bike with 1 new spark plug (the inner plug doesn't want to come out) and the old coil. Initially, it wasn't running very well, running for just under a minute and then shutting down, just like before. Then a mechanic friend from Nairobi called and told me to unplug the generator (3 yellow wires) and start the bike. It started fine and ran great for 5 minutes, no issues. He suspected that something's either wrong with the Rectifier or the generator coils. I plugged the generator back in and bike continued to run fine for another 5 mins at idle. I checked continuity across the pickup and power source coils and both are within range - tested after engine was hot. I checked voltage across battery terminal while running and was holding steady at 13.35 at idle and dipping down to 12.2, 12.4 at high rpms and then quickly back to above 13.0. So it sounds like rectifier is fine. I checked AC voltage coming from generator at idle and was getting readings around 30 volts.

He said if bike is running at all then it's not a CDI issue because if CDI is faulty then bike wont even run. Is that true?

So the bike ran great for 10 mins and then I shut it off. Im going to go for a test ride tomorrow. But not sure the problem is fixed. I think something's up with the electrical power coming from engine to CDI that's spiking and causing CDI to shut off the bike.

What can I test further to root-cause this issue?

I have a spare rectifier that I'm going to mount tomorrow.
