When i had my rm 125 out last week it was idleing odd, it would idle high for a couple seconds then idle low then shut off, and when i was riding it i could literally let go of the throttle and it was idleing high enuf that i didnt have to use it. I went to look in my oil and noticed that the rod of my dipstick was missing, could it have gotten chewed up and messed up my case?

Any help please!

 

drain your oil and see if there's anything in it?
