Put a new OEM cam chain on My '03 KTM 250EXC 4 stroke with 300 hours and it made those same noises go away. It battery starts better and when you shut it down it sounds better and when you kick start it, it's easier. It howls less when going down the road in 6th.
Hey!!! Yes my bike does same thing and same noise. Doesn’t do it all the time but when it starts it seems to stay. But a bigger question is how you got a 2017 crf450r with electric start? I thought 2018 was first year for electric start. Thanks for the fix though definitely the issue with my 18.
@@ShadowKnight7171 Alright boomer, ill continue to take good care of mine, and you can continue destroying the value in anything you own. What a clown XD
Hey I really need some help. I have a 2020 crf250r everytime I let off the throttle I get this friction skimming sound like something is spinning and rubbing against something. It goes away immediately when I pull in the clutch. And when I try to recreate the sound when i put it on a stand with no load the sound isn't really there. You kind of hear a noise but it's way more quiet and might be something else even or normal. But when I ride the noise is there. It's the only video on my channel if you want to hear the noise. I'm guessing like a countershaft bearing possibly?
I have a 2015 crf250r with 381 hours on it. It still runs strong, but I have shimmed the valves twice now. It can't possibly last much longer so I'll be rebuilding it this week.
