KLV1000 long run dying issue

[pichulec]

Hello All. Yesterday I was coming back home from Lake District and after about 150miles of riding with constant 70-75mph on 4k rpm I decided to leave M6 due to roadworks speed limit. When I reach the roundabout the bike just died. I could start it but as soon as I leave the throttle to idle position - it will die. Funny thing is if I cycle ignition, it will start as nothing happened (you can see that on the video).

I had that issue before, it only happens after very long ride on motorways. Suzuki dealership mechanic told me last time that throttle bodies top cover popped out and bike was getting too much air. I really don't know if it is the case. Any thoughts will be appreciated.

Hi I had exactly the same last year after a run of 120 miles of similar speeds I slowed down for road works and it just cut out just like yours I to managed to start it again but it was running like yours not quite right the temp gauge was on normal I made it in to the services let it cool down for half an hour it then started fine so I went to the fuel station in the services and topped up it ran fine all the way back home I had filled up at a supermarket earlier that day I wondered if it was a ruff lot of fuel?  it has not happened since, hope you made it home OK keep us informed

Perhaps the fuel tank breather is blocked and a vacuum is forming as fuel is used?

Worn TPS maybe

Two issues come to mind that may cause your symptoms. Firstly the fuel pump issue, maybe loosing pressure and secondly the TPS .

What about coils? I posted this on FB and one bloke had same problem, and in his case the coil was failing?

[kwackboy]

A coil issue wouldn't cure itself when you turned your ignition off / on

Edit ... I will add though that coil issues are not uncommon .

Coils may behave differently depending on their temperature (assuming they are faulty)?

When last time I was in Suzuki dealership, they told me that throttle bodies popped off, like in this topic.

I am having mine serviced next week so I will get my mechanic to check my throttle bodies as well

It's unlikely to be the throttle bodies popping off as the bike would not run properly again until they were re-fitted. It would be worth checking the TPS and making sure throttle body fittings are in good shape and properly fitted and tightened if you're getting the bike serviced. My Vee very occasionally cuts out in a similar way to yours when coming to a halt after being run hard. It seems initially that the tickover is too low and the engine just dies. It always starts again instantly and then ticks over normally and runs fine. It's never been enough to bother me. So maybe the TPS does need a look?

@Hookie thanks for the info  I will get him to check through the whole bike I have been using the same bike mechanic for 40 years
