Hey folks,

Just attempted to start my DR650 (2015)......having a few problems

She idles fine but as soon as I put 1/3 -1/2 throttle the engine starts spluttering and if you put more power on after this she will cut out

Can anybody advise me what to check before I start taking the bike to bits? I just put some new fuel in the tank and it made no difference

I will attach two videos of the problems (apologies about the exhaust noise!)

First video is of me opening full throttle.

Second video is of me opening it to when it starts spluttering for a while, then opening all the way until cut out.

Any help would be greatly appreciated!

Check fuel flow into carby float bowel .. remove float bowel, put a container under the carby and open the fuel tap ... if it does not flow but dribbles you have a blockage .. possibly in the plastic filter fitted to the carby inlet.

clogged jet(s). this has happened to me several times as my DR sits for extended periods in between uses.

Turn off the fuel .. and then let the engine run - pulls most of the fuel out of the jets.

This responce is to teevee and is prevent blocked jets ... not to fix the original problem!!!!!!!!!!!!!!!!!!!!!!!

been there done that and still got gunked. even ran it dead then drained float bowl using screw. seems as though the utterly horrific gas we have in nicaragua will kill just about anything that sits. it's gotten worse over the past several years as fuel quality has worsened.

since ethanol seems to be the culprit to a large extent, what i'm going to try this year is making up a few gallon batch of de-ethanoled fuel and run that through the system for storing after draining the pump gas from the last trip.

At least some of the lawnmowers around here stipulate that ethanol based fuels are not to be used ...

Mr DR650 has just been sat for 7 weeks while I was away at work

I will try turning off the fuel and running her for a bit

Thanks so much Back in a while!

I tried running her for a bit.......no luck

Could somebody tell me what I need to do from the following diagram? Not too familiar with these things to be honest

http://www.vincestrangmotorcycles.com.au/carby.pdf

I'd start with taking the float bowl off the bottom of the carby, and then taking the main jet (14) out. Look to see if there's anything blocking the jet hole, and blow it out. If you can't see it clear after blowing, poke something soft, like a piece of grass stem into it, or a blast of compressed air. Never use anything that is tougher than brass. The jet is a precise size.

Cheers

Nigel

That is to prevent teevees problem! And possibly you should use it too to prevent future occurrences. Works on lawnmowers too.

Remove the float bowel. Turn the fuel off first.

To do that there are two screws on the bottom of the carby - screw #36 shown in your pdf diagram ... only one screw shown but there are two.
The flow bowel is not numbered in your diagram ... but screw #24 is fixed to it.

Now turn on the fuel and check that it flows out on to your boots. It should run out freely .. not dribble. If you want to avoid wasting fuel then put a container under the carby. If it does not flow out freely ... then check its flow out freely from the black rubber tube that runs from the fuel tank to the carby. Item #23 is the plastic filter that can get blocked .. remove it and clean it if required.

If it runs freely then do as Nigel suggests ... I'd use a nylon fishing line as the
probe, item #14 is what you want to clear ... it is brass so yellow coloured and has a small hole in its centre.

Good luck.

-----------------
Ar .. see you have done the deed .. fairly easy to follow your nose. Harder to type it up.

First thing I did was to replace those carby bolts with stainless steel allen cap heads ... past experience say those bolts will seize and be impossible to remove. I'd even be tempted to put torqueX bolts in there! Put some 'never size' on the thread of these bolts .. no matter what you put in there (and I'd not use the bolts with damaged head here).
