Eddieb's DR build thread.

[Eddieb]

A question for the Nordmeister and anyone else that has installed the FCR39 onto a DR

There's 2 lots of wiring coming out of the carb, one is TPS and I'm not sure what the other is. Both can be cut off and thrown away?

I've installed a Merge AP spring and extended fuel screw into it today. Apart from the 2 wires I think it's ready to go onto the bike!

I've also removed the preload spacers from the front forks of the blue bike so I can take them down to an engineer next week and get 15mm cut of each one to account for the Intiminators. I picked up some 5w fork oil yesterday in preparation for that install.

Mine only had one set of wires but you dont need any of them. I just left mine under the tank.

[NordieBoy]

2 sets?

I removed the TPS wires and bunged a pair of pliers on the TPS shaft, broke it off and taped over the hole.

Yep, 2 sets. One lot goes into the TPS, I'll probably leave the TPS unit on and just chop the wires where they enter it, unless there's a good reason to remove the whole unit. The other wires come out at the bottom of that same cover the TPS is mounted on.

I removed the unit as it touched the IMS tank.
I can also only pull the choke on a fraction and for a fraction more have to push the right side of the tank in with my knee

Thanks Fran, are you using the bar choke or the stock FCR little pull out lever?

[Eddieb]

Eibach spring was installed onto the shock and refitted into the bike today also. Ready for some FCR goodness.

[Phreaky Phil]

I asked MXRob about using the remote BST choke on the FCR and he said that they will fit but can be a bit problematic, so I stuck with the FCR choke. Theres plenty of room with the Safari tank and the throttle cables are on the right side of the carb so they dont get in the way like the BST cables did with the carb mounted BST choke.

Stock FCR. My bar mount one was removed from the switchgear with a dremel years ago.

[Eddieb]

mmm AP timing on the FCR carb not going as planned, partially I think cause I don't really know what I am doing. Carbs are a bit of a black art to me.

To refer to MX_Rob's guidelines
https://docs.google.com/present/view...dhb295f8&pli=1

I've got the carb hooked up to the tank and if I depress the black timing arm fuel is squirted onto the slide, however, if I turn the throttle cam I can't see fuel spraying anywhere. I've tried winding the screw adjuster on the timing arm fully in and fully out and I can't get fuel to spray on the slide by turning the throttle cam, in fact it doesn't seem to be spraying anywhere.

Compounding this is I seem to be getting quite a lot of leakage from the bottom of the carb somewhere, and from the drain in the bottom of the carb. I can't tell if it's leaking from the bottom of the AP pump or the jet access cover but I'm wondering if this is causing a loss of pressure so that it's not spraying when I twist the throttle cam. Depressing the timing arm directly I can press it quickly, however using the throttle cam is much slower so I'm wondering if it's loosing pressure between twists due to the leak, between the 2 leaks it's losing quite a lot of fuel.

I pulled the AP pump cover off and the mating surface does seem to have a bit of damage so thats probably it, but it's not obvious that thats where the leak is coming from.

Anyone in Wellington ever done this? I need to get it sorted in the next 2 weeks for a ride.

[NordieBoy]

I had to wind the screw almost all the way out to get it to to just miss the slide.
Does sound like there's a bit of a leak.

In all my mucking around with the FCR, the best info I could find was here (about the accelerator pump anyway). The site in general is really good, and enabled me to find quite a few problems with the various carbs I had. Good descriptions of what is normal etc.

From memory, I did not have any problems with the squirt hitting the slide. With things set right it is a work of art. This site had some really good pictures that showed setup too. I ended up fixing the carb to a post, (like the pics lower down in the jd stuff) with a small tank feeding to it, and followed these two guides. I had the ap spring mounted in the wrong place in one, and another had a hole (that was not supposed to be there!) in the leak jet part. Both ran on bikes before I worked on them, but worked much better when set up right.

Heya Eddie

Did you do any revalving in the shock or just uprate the spring?

[Eddieb]

Just uprated the spring at this stage, the spring came with the Yellow bike so I've just swapped it over. I find the spring a significant improvement but I'll ride it some more and decided and whether I want to change the fluid as well or not.
At this stage I'm not considering actually revalving the shock as the cost/benefit doesn't stack up.

Yeah that is where I am coming from, I bought a YSS shock on tardme for $200.00 about 4 weeks ago http://www.sella.co.nz/motoring/moto...r-sale/8y8l7w/ , the spring is slightly heavier, .30 mm bigger wire dia so a little better with load than factory.

Damping is great and very adjustable, we wonna get another one or something similar for Ellens bike so looking at options so would be interested in seeing how yours pans out.
