I am the p.o. And I can assure you that you are way off with your last comment. I AM mechanically inclined and have offered any assistance possible to deep.Humm, something not right for sure? YouTube is tough for figuring out sounds but it sounds lower and deeper than a roller tick. Of course pulling the rocker box off is first up, check for the intake roller bearing to be worn and or loose. If it's really bad the cam is probably shot as well. If it is the roller and it is really worn, I'd be talking to the PO. If it didn't sound like that when he bought it and it's really worn, the PO adjusted the valves and sold it to keep from having to deal with it.:headshake
Keep us posted.
I would stop riding it immediatley. If it is the lower bearings, you are waiting for it to destroy the bottom of your motor. If you are friends with john (orangeshirtdude), then you surely know Dodge131, he is pretty knowledgeable with the KTM's. Hit him up for advice and / or assistance in fixing your broken machine.Thanks for posting this John .. Me and Noah went to rock creek park and it started making the noise all of a sudden .. I rode it maybe a little over a 100 miles .. I did notice the oil looked really dirty .. I did find youtube video of a guy with similar noise with crankcase bearing issues. I am tempted to open the sucker up but with no experience on working on motors / no garage not sure I should venture into it .. I actually rode it to school hoping the noise would "go away" .. nop!
*edit* the guy from the bad crankshaft video says it happened to him within minutes also so that is not out of questionCould be so many things
Broken Balancer shaft
Balancer shaft bearing
crankshaft main bearing
and probably more possibilities but some thing that can go bad in a matter of minutes is more likely
I am riding it no more. Dodge has seen the video and he thinks its bad and needs rebuild. I sure will be bugging him a lot!I would stop riding it immediatley.
