Lumpy on a steady throttle + stays around 2.5 - 3k on closed

Postby nige » Sun Aug 20, 2017 3:40 pm

Guys, bike is new to me, 990 SDR's are new to me. I am sure all the answers are in the search, but not sure what I am searching for.

So around 40 - 50 mph the bike is very snatchy on the throttle, kinda on a steady throttle attempting to keep a steady speed. Also on a closed throttle the bike seems to want to hold its revs.

Bike has a full Akra system on it and the guy I bought it off had the Akra map done. Bike is a 2008 and has only done 3250 miles. It had its 600 mile service but has never been back to KTM since, he only ever did about 300 miles a year. It has had regular oil changes and the MOT's reflect the mileage. He has done a couple of track days blah blah

This morning I did the reset thing. Turned it on cold, did not touch a thing ran it up for 15 and a half minutes, fans were cutting in and out. turned it off. Left it whilst I got my kit on and then turned it back on and took it out. Did not notice any change.

Just lumpy and snatchy with the high revs, I noticed when I came back that it was hunting between 1.5 and 2k revs on idle.

Do I simply need to get it into KTM for a good seeing to ???

Do you have TuneECU cable and software?

Sounds like it's hunting, I would recommend a few things.

Clean and pack BCG with dielectric grease.

Acquire Tune Ecu cable and check that TPS is not our of adjustment then also check that the throttle bodies are in sync.

cheers guys - As I am the new owner, decided to put it into KTM for a full service and diagnostics. Think of it as baselining my ownership :D

Hopefully they get it sorted. Let us know what they find.
