DR650 starting problem

[>>Thump°C]

Hi

My son's DR650 normally starts fine, even in the morning.
But twice now, in the early evening, it started, ran for a few seconds and died.
then it would not start. Battery is still good, it turns the engine quite a while before starting to go flat.
I then jump it off my car and after many turns has a few false starts and eventually runs fine.

happened last week and again today.
bike has been ridden in between without problems.

We're going on a week trip next week, so it's a conbcern.

What do I look at.
water in fuel? but would that not give problems while riding anyway?

Please help

Does it not flood?

Check for dirt in the carb. Get carb cleaner and rinse. Then use pressurised air to clean the jets. Also give your airfilter a clean. And the little airfilter under the seat that attaches to the carb.

Eliminate this first, I'd say.

No I don't think so, it's the same way he always starts it.

Here's a pic of the procycle replacement part:

He refers to it as a "vent filter". The stock one looks like a little plastic bell. Inside you'll see a tiny foam filter. Pull the plastic unit (ít's sealed) and dunk the entire thing in a small container of paraffin. Shake well. Allow to dry and reinstall.


Unfortunately, I don't think this is your problem - I think you may have dirt in your carb or an obstruction in your fuel line. But clean it anyway.

Can't hurt to pull your plugs too and check them ...

Check fuel tap:
Turn to PRI and see if problem persists.


Replace plugs & clean air filter.


Then clean carb.

What Lecap said:  it sounds like a fuel problem.

What does the PRI actually stand for?

I fitted spots on my bike a few weeks ago and twice now we had to run start my bike, we connected it all  correct through a relay and it has a switch, so not sure if it is a battery problem. The bike stood for almost 2 years before i bought it.
