990 Fuel injection problems
 
My 990 has 14000km on the clock, and recently started giving a FI error code 49 Idle control motor malfunction. KTM here were told by Austria to replace the Throttle Bodies. This worked for about 4hours then the fault came up again. At first the bike seemed to idle fine but as the throttle bodies were replaced on a Friday I would have to wait until today to get it back to KTM. Yesterday being a Sunday I wanted to ride. On first startup the bike stayed idling at 5000rpm and would not come down. Took the bike to the petrol station to fill up. After second startup and bike up to operating temperature the bike continued to idle at 5000. Rode bike back home. On the third startup the idling came right. rode the bike for most of the day with no problems. Went to the local and after a couple of hours of standing the bike would not start. It would crank but not fire. After a couple of tries it fired but would not idle. I am going to try a cold idle for 20 minutes to try and reset the computer.
My question is, is there anyone out there that has experienced this same problem and what was done to rectify it.

In cars - 90% of the efi problems are connector releated.

I'd suggest you clean and check all the connectors around the 'black box' and your throttle bodies.

Test each wire as it entres the connctor .. while the bike is running - if it changes the 'tune' by flexing/pulling/pushing on one wire you may have found the source of the problem.

Spoke to KTM yesterday evening. They have received a point by point test sequence from Austria, so hopefully this will find it!!!!
