Fun With Carbon Fiber

Good morning everyone!!

A month or so back I decided that I wanted to recreate all the body parts of my DR650 with carbon fiber parts. I started a thread to share my progress learning how to do composite work and making the pieces for my DR. The last part that I will make will be a Dakar style fairing with a dash to hold all the goodies that we need on our bikes.

Lots of people have posted greats tips and tricks on the thread and I've included a great resource page to help others get started.

Follow along and if you're interested in making carbon fiber parts for your DR, do it! It's really easy.

All three bearings, the on in cush-hub, and the 2 bearings in the wheel hub.

I did find this:
hub: 20mm x 47 mm x 14 mm
cush: 25mm x 52mm x 15 mm

Correct?

Thanks,
Thanas

Now What?

Thanks Derek:

So, will this enzyme additive work its way out after a couple tanks or do I need to drain the fuel? I added it to one tank. I've refueled only once so far but did not add any more startron. It is still not running well in first gear or on start up.

Thanks again.

I just got a Seat Concepts Tall foam kit and it is awesome! It made room for my knees and is very comfortable. There customer service is excellent. I called and talked to one of the owners who basically told me I could have any cover option I could dream up for $160 with free shipping for mentioning ADV. I got a carbon top with gripper sides on a tall foam. The install was a breeze and if you don't like how it turns out you can always pull the staples and do it over.

I don't know for sure if your additive is at fault, but I do know that the need to use the cold start enrichment longer indicates a lean issue with the pilot circuit. I would replace the float needle if the tip is found to have a witness line, set the float height with the help of a float height setting tool to 14.7mm, replace the pilot jet and set the idle mixture via the following method:

Start the engine and warm it up. Set the idle CO to 3-4%. Set the idle speed to 1500 rpm. If you don't have a way to measure CO%, lower the idle speed below the factory spec. Starting from a setting that is known to be lean (1-1/2 turns is likely but not guaranteed to be), adjust the fuel screw to obtain the highest idle speed. Adjust to 1/8 - 1/4 turn richer than that. Then, adjust the idle speed back to 1500 rpm.

For diagnostic purposes, the gear is mostly irrelevant. Throttle position is the important thing:

Put some tape on the throttle housing and the edge of the grip. Mark zero throttle with a sharpie. This is best done with the engine idling, so you can tell when the slack in the cable has just been taken up. Turn off the engine and mark wide open. Now take a tape measure (metric works best in my opinion) and measure the length of the arc. Put a mark at the mid point. Duplicate this procedure to mark the mid-point between here and zero throttle opening to get 1/4 open. Repeat for 1/8 and 1/16 openings. With the help of the marks, determine precisely during what throttle opening(s) it misbehaves. Don't have an accident trying to look at the marks while riding. If you do, I'm not responsible!

Regards,

Derek

To what is the front axle supposed to be torqued? I just r/r my front tire and don't have my manual to let me know the torque of the axle or the four axle nuts. I think the rear was around 70 - 75...but I can't remember the front. Thanks.

This procedure will work for most other bikes but on the DR650 setting the mixture screw this way will often result in a slight "rich bog" just off idle. If you aren't going to make other changes to avoid the rich bog most riders have good results turning the mixture screw about 1/4 turn leaner than the highest idle.

I've been involved with 2 attempted rotations and both abandoned due to the amount of force needed and concern about breakage. This was with the carb held securely in a vice and the use of a heat gun to try and expand the body a bit away from the pipe. We cut them off, and threaded it and fitted a straight pipe to both.

Others have had no problems.

Good luck.

It didn't work that easy for me. Tube started to kink, so I left it alone. As a test, with the pig tail, I ran the tank dry. Curly Q did not air lock. Ran the tank bone dry, including sloshing fuel from the right side.

Wait a minute. Which way is leaner, turning in? Thanks.

My experience as well. I gave up and lived with it the way it is.

the other option is to to buy a TM40 pumper carb
