When you have the tank off carry out some checks to the TPS. I've seen similar symptoms in a couple of Wee's. Here are the parameters . Hope you get to the bottom of this problem

Most of the time, TPS problems do not show up on tests. I'd replace it at any hint it might be a problem.

Bike safely transported back from Birmingham to West Wales. Assuming I am not doing anything daft, then the following is a flow test with dismal results.

Also some images showing sediment from the Tank.

This is the Laboratory

The test.

The result! (that's not 1200ml)

Sludge

That's pretty much what I expected based on the symptoms.

Do you think the external filter mod will resolve this? The Pump does sound like it is doing its job.

I've seen the images of drilling between the walls in the filter to allow fuel to flow but if I'm honest I'm not clear on the whole mod

I'm also looking for (sensible) solutions for cleaning the inside of the tank

The problem is the K7 and later 650 pumps are different from the pumps the original modification the article covers. They are covered later but one of the pictures is missing. It takes two aspects to properly align the drill. I think I would feel better replacing the filter/regulator #15610-27G00 and the strainer #15420-05H00 but the valiant or the cheap could try figuring out the drill angle.

Parts ordered, look out for the next flow test video to be shown soon on a screen near you

If the parts are on order try the drill on the old one and see how it goes.

Just out of interest, are you fixing it for the new owner or did you take it back? Does this make you a proper dealer now you offer a warranty?

Fat Rat · « **Reply #50 on:** February 26, 2016, 20:59:54 »

I would never sell a bike knowingly faulty. I am fixing it for the new owner. Once it has been tested thoroughly and running how it should I will take it back to him.

Nothing to do with warranty, just about doing the right thing.

I'd use your shop if you owned one .!!

He could start a dealership with all the bikes he's got.

Rusty Nuts · « **Reply #53 on:** February 26, 2016, 22:18:14 »

Plenty of courtesy bikes and test rides, then?

"just about doing the right thing". I feel the same Fat Rat, sold my VFR in September (locally) and told him he's got two weeks to check it out and if there's anything wrong I'll sort it, then to bring it back after 3k miles and I'll show him how to change the oil/filter adjust the chain etc. He doesn't think it's as easy as it is!
He didn't bring it back but saw him in the pub the other day and said he wants to take me up on the offer of a "service" in a month or so. He'll bring the parts and I'll do the labour!
Line of sight warranties aren't for me.

You are going well over what most private sellers will do. Good egg.

Much appreciated indeed

That Fat Rat eh! what a good bloke. I bet if he ran a bike club lots of us would join... errr oh! hang on a minute.

DL650AK9 Service Manual page 223, pump fuel discharge amount: min 168 ml/10 sec (could somebody check that I am looking at the correct info) so not sure where the 1200ml/30 sec value has come from.
On the video it looked like you had still got less than even this lower figure but I thought it might be relevant when you do the next flow test.
Intresting thread, own a K9 that was sat in a dealers for quite a while before I bought it and though running OK wondering whether to check mine...
