Help 950 has no power

[Ashley M]

I have a problem with my 2003 950 Adventure I had to get it recovered by the RAC on Wednesday, it will start and tick over but when you rev it, it doesn’t sound right and if you try and pull away it has no power its like pulling away it 4th gear, I did manage to ride it I few miles and when I looked into the end cans they were white like its running very lean, anybody got ant ideas

I'm not sure what's wrong Ashley but have you posted this question on the KTM.UK forum, there are a lot of wise dudes on there

Hi Bob
Yes i have, i did this one as well just to try and get as much help as possible as i'm completly stuck as to what is the problem

I believe that the 950 has exactly the same Mitsubishi fuel pump as the Africa Twin and your problem does sound a little like fuel starvation.

[Ashley M]

Thats what i was thinking but if i urn it key i can here the pump running

Have you had the tank off and maybe pinched a fuel pipe?

[Ashley M]

No i haven't had the tank off in months, it happened near the end of the second day of green laning i filled the tank that morning and had done about 85 miles when it started to run ruff

I read a thread on ADVrider where a rider's 950 didn't run well...

I got the Crud - ADVrider

In his case, the jets were blocked...

Good luck with finding and fixing the problem!

Hi Ashley,
I have had similar problems with my 950, a couple of times it has stopped running for no reason out on the road, both times it started to run again after a couple of restarts while still sitting on the bike. Then again the other day I started the bike after it had been sitting in the garage for a couple of weeks, the bike started ok but would not rev. I tried and tried until the battery went flat. I charged the battery for a couple of hours and decided to have another go, still the same. Eventually I decided perhaps its a fuel blockage so I put the bike on the centre stand and rocked it forward and back as well as side to side pretty violently. I put the key in and started her up, she revved freely straight away.

Don’t ask why I thought shaking the bike would help, I just though what if its crap in the bottom of the tank or something and guessed a good shake would stir it up. The bike will be going for a service soon so I am going to ask that they flush the fuel system.

KTM ownership takes a true petrolhead attitude, what Clarkson says about Alfa’s is true for KTM’s in the bike world. When they run they are fantastic but its only a matter of time before they cause you heart ache.

The story so far, it turns out its not running weak as I first suspected, the reason the exhausts are so white is the at the rear spark plug is not firing which means the un-burnt fuel is going into the end cans then burning off which is the cause of the look of the exhausts, I changed the plug it run for a while then the plug was all fouled up, cleaned it and it did the same thing, long story into a short one, engine out rear cylinder off and found a small piece of metal in there but I can not find any damage to anything and nothing obvious as to were the metal has come from , apart from this the piston, barrel and head look in very good condition the bikes done 35,000 miles and has a full service history

Thanks for all the ideas I'll let you all know if i find the cause
