Posted: 09:20 - 21 Apr 2019 Post subject: Bogging down on long ride |
|
|
The KTM. I rode it all last year with no issue. Took it for a service a couple of weeks ago then didn’t ride it immediately. This weekend I went for a 100 mile ride on Friday, to a place that was booked to remap it to cure the usual KTM snatchy throttle and generally smooth it out. After about 70-80 minutes riding, it started to bog down if I opened the throttle fully in a high gear, such that it wouldn’t accelerate. If I eased off it would pick up again. No FI light, no stuttering or misfiring, just no drive.
It then got gradually worse until a couple of times it cut out. I was able to restart it immediately, before even coming to a stop and it would then go again but was still not pulling right. I got to my destination (hotel) and checked the obvious things. The only thing I found was a loose positive battery terminal, which I tightened. I took it for a test ride and it all felt ok, so that was that, I thought.
Next morning I took it to BSD Performance for the remap. I mentioned the running issue and battery thing. I also struggled to start it that morning due to a low battery, but it eventually got going.
They had it a couple of hours, did their thing and talked me through all the mapping changes - they never saw any running problems on the dyno or road tests and the dyno curve I have looks fine.
On the ride home, the same thing happened, after about the same time riding. I got it home and parked it and haven’t had a chance to investigate further, but I am thinking fuel starvation. Maybe a blocked filter or dodgy supply line? Or even the pump?
Any thoughts from the collective on this? Or experience of the same thing? ____________________
