Eddieb's DR build thread.

[Eddieb]

So today I head over to BMWRSNUT's as he reckons he's got the gear to get my lower suspension bolt out.

1) 2 minutes work by Stephen and it's sorted and the bolt is now in the lower position, as it happens he didn't even need to use the hair dryer, it was all muscle.

2) Stephen had to check his hair with the 'Professional Hair Stylest' hair dryer before we started work

With the rear raised the bike is considerably higher, it made much more of a difference than when the front was raised on it's own.

Hey guys what are these carbs off that you are using? I just had a look in the shed at the grenaded yz450 engine which will never go again it has a KEIHIN Flat CR carb looks like 39mm. Is this any good to anyone? HIGHEST OFFER NOT NECESSARILY ACCEPTED but probably will be.
GSers

what other yz450 bits have you got?
front end?
exhaust cam?
exhaust system?

[GSers]

That the right area, the DR requires a FCR-39MX.

FCR = Flat Slide Carb MX = Motorcross 39 = Venturi size
This one is off a 2005 450 with throtle position sensor Part # 5XD2 10RJ03
and has a 39mm venturi

Does it have the air cut off valve?

I bought nearly a complete bike that lunched itself IE it aint going to be running again anytime soon. ( never )
I am using the front end complete including plastics seat rear subframe rear shock
for a HPN BMW900RR sort of bike.
There is sitting in my shed what is left of the motor gearbox I think it dropped the cam chain front pipe rear swing arm and wheel, linkage, frame, carburettor, coil, radiator x 1 and ignition box No rear exhaust
The engine was stripped at the bike shop before I bought it and turned up in boxes I have not looked at it very closely at all.
What do you want me to have a look at specifically for you or make me an offer for what is left
This bike I can tell was not very well maitained used for a hack.

Nordie
I think so, but looks to me like it is cable operated showing in the correct place from what I can see on the KEIHIN website.

You beat me to it, welll the front end part anyway, already have muffler

Right back to Eddies Dr build thread.

Sooo.... Is this the right one Nordie? - Been toying with the idea of the FCR40 but $$$$ always get in the way. I guess a 39 would work about 2.2% less efficiently than the 40...

Making up adapters should be no sweat, reckon the YZF cables are long enough? as for jetting.... Probably, maybe, er better get an advrider login and start trawling!

Hijacking again! Back to the thread...
BTW I found a nice big ally road sign buried in weeds at the side on the road (when looking for the spare wheel that fell off my trailer) so loose a wheel - gain a new bash plate for the DR Silver linings!

I took the DR out today for a play on the beach at Wanuiomata. Took it through some very soft sand and it ploughed through that not too bad with the E-07 fitted, it was soft enough for the bike to stand up on it's own without being dug in.



On the way back in I tried standing the bike up with no stand again for a photo, which resulted in this



And thats where things got interesting.

After picking the bike up again it wouldn't start, the battery quickly ran out of juice to turn the motor over. After a short wait a quad turned up and towed us back to the car park where it crash started easily.

The ride home was uneventful and we made it without stopping, I chucked the battery on charge and the charger was saying it was fully charged after about an hour. Is the short discharge and quick recharge an indication it's stuffed?

Once the battery was on charge I started writing this post and discovered I had lost my camera, oh crap! it's only a cheap one but still $150 worth, and that would also mean I'd have lost todays pics.

We jumped in the car late this afternoon and headed for the beach. We figured we'd re-walk the track we came out of and sure enough, half way back to where the bike had fallen over the camera was lying beside the wheel rut, phew!.

[DR650gary]

Reinstall the battery and put the multimeter on when you turn it over. Should drop to around 11-12 volts. If it drops to below 10, almost certainly stuffed.

Great photos, looks like a good day and you got your camera back!

[Eddieb]

Thanks Gary, will try that out.

The DR headlight is hard wired on obviously, and my bike is also fitted with running lights so the indicators are on constantly also, this means there's a bit more draw on the battery than usual starting up.

I think long term I might wire switches into both circuits so I can turn them off as required.

Dump or LED the running lights. Or even put the blinkers on when starting it.
There's 42w running constantly there if it's just the front ones.

The 39 flows better than the BST 40 as there's no butterfly in the way of the flow.

That cable out the top is the hot start cable.
The air cut valve is on the side and is missing from that one. The accel pump bleed valve is closed on that one too but if you put on an adjustable one then you're meant to block it off anyway. If you run without it, it'll bog heavily on slow throttle openings and at low speed will stall (as the YZF riders will attest). The bleed valve shunts more of the flow back to the float bowl at slower openings.

It'll work but backfire more than one with the air cut valve.

I've got one the same one on the shelf for parts that I may convert one day.

While I was putting the bike back together last night I found a loose plug under the rear end of the tank. It has a red and a black wire. Is it supposed to be loose? anyone know what it's for? I couldn't find a mate for it.
