Question about 2003 KTM 640 Duke 2
Battery charged and checked,started this morning first time killed it tried again would not start just whirred.
Remove the sparkplugs and ground them to the engine try to start check for spark at plug if sparking check for compression put your finger over plug hole try to start if it pops off check carb for gas (didnt say if it was running and then sat for a while) with spark and compression and good gas it should run if your finger dosent pop off then the problem is no valve movement to create compression(broken cam chain) that would allow the engine to roll over quickly or whirr as you said check these things and let us know
