  1. Hey guys, While riding this weekend my bike started giving me a new noise I've never heard before. Any time that there is an initial onset of engine braking i.e. when I down shift, coast and let off the clutch, or let off the gas without using clutch, I get a sort of squeak from the engine. It doesn't last but is just a quick squeak. I honestly have no idea what it is because I have never heard it before. Maybe its time for clutch plates or a basket? I would really appreciate some input on this. If it is of any significance the bike is a 2008 KTM 250f. The best thing I can relate this sound to is a car with a squeaky suspension. Although its not my suspension, it's definitely something else. I can provide more info if anyone thinks it will help. Thanks, Mark.

    Clicking when giving throttle

    So im not very experienced with bikes and ive started to notice a click. You can hear a clicking noise as soon as you give it throttle, only when you start to throttle never anytime else. Any help would be much appreciated.

    kx250f God Awful Noise KX250F

    I recently purchased a 2010 KX250F from a friend of mine that had been sitting in his garage for about 5 years. The bike seemed to be in decent shape and the price was right so i picked it up. I went through most of the bike before riding it (air filter, oil, greased all the bearings, adjusted suspension, changed all the fluids, etc) The valves sounded a bit loose so i decided to have a "Buddy of mine" adjust the valves. I get the bike back, go for a ride and the cam chain tensioner falls out while i was riding, luckily i caught it very soon after it happened and it never jumped timing. I put the tensioner back in and continue to ride the rest of the day. as the day goes on the valves sound much looser than they were originally before the adjustment was done, I decided to call it a day and tear the bike down myself. I shim the loose valves and button the bike back up, but now the thing sounds god awful. Straight up clacking coming from the right side of the top end. Since then ive probably had the bike apart and back together 4 or 5 times trying to figure out the problem. Its not the auto decompression valve, every valve is in spec, timing is solid, and the cam chain tensioner is working fine. I'm stumped. anyone have any thoughts?

    Help Diagnose Engine Noise - XR200

    Hey guys - I have a bud with a XR200 that is having some engine noise that he cannot identify. I'm posting the vid for him in hopes that the forum braintrust can help get the right diagnosis. Notes: He has adjusted the valves and the cam chain tensioner. I have asked him to confirm that oil is getting to the top of the valve head. Hopefully he can reply to this thread with more information. @XRepublic Appreciate any and all input :-)

    Who knows what this is?

    Just did a cam rebuild strictly by the service manual and now there is an intermittent ticking coming from the cam cover area. Does anyone know what this is?
  6. started to make this noise when i shut the bike off anyone know what this is or ever run into this problem? thanks,
  7. I have a '02 yz85 and today I replaced the right side crank seal, head o-rings, and swapped out the head for a VHM performance head. I also put a FMF SST pipe on it with a FMF Shorty. The bike has been working perfectly all day, other than running poorly since i need to rejet. But no other problems then that. I came into the garage about 5 hours after riding, and noticed that when I turned the kickstart over, theres some grinding noise. It did not do this after I put it back together, it just started out of nowhere. While I was putting the clutch back together I noticed the shaft the clutch goes on moves in and out, I called my friend who has replaced the clutch on his 85 and he said it was normal and his was the exact same, so I didnt worry about it. After I put it back together it was not making this noise, and didnt make it after riding either. Just started out of nowhere. Heres a vid to show what it sounds like. I don't remember it ever making this noise. I took the clutch apart to make sure nothing was wrong, I didnt find anything wrong except a little gasket maker that got onto the clutch since I put too much. Doesnt feel like theres any resistance while kicking it over, in the video the spark plug is out. Help?

    crf250r ticking

    I have a 2004 crf250r that is making an awful ticking noise, it will start but will not stay running, it also will not start with the choke on. I know it is not spark nock. i am looking for suggestions on what it may be as well as the fix as i would prefer to not take it to a Mackinac. Thanks Grady
  9. Anyone heard this noise coming from under the gas tank when throttle changes? 250 miles 2017 rally. No mods.
  10. This noise is really bothering me. I want to know if it's something to worry about or not. I checked my valves they are in spec. Please Help!
  11. Hey guys, could use some help here... I have a 2008 KTM XCR-W 450 with a new engine knock sound coming out of it. I noticed the noise yesterday and it just seemed to get worse throughout the day (Possibly placebo effect...). I'm positive it's a new noise, and I'm not too thrilled about it. Bike runs perfect, power delivery is unaffected, it's just noisy as heck. Knock is most noticeable at idle and on deceleration, but goes away as soon as it revs. Also, pulling the clutch in while at idle also stops it. I've read about a few things that could cause noises; loose primary nut, timing chain, cam tensioner, etc. However, it's worth noting that the bike only has 30 HOURS on it (I bought it at 14 hours in spring of 2016 from an older guy who bought it new and never rode it, and I expediently broke my leg soon after, so I haven't had much seat time either). I find it hard to believe that something big like those things could be bad after only 30 hours... Anyways, see following link for video of the sound it's making. https://youtu.be/fNf0Nc_XNzQ I have a big camping trip planned for Dumont in 3 weeks, so I'm a little rushed to fix this... And it seems most of what I've read about is over my head, so I'm very heavily debating taking it into a dealer and letting them deal with it. So, two questions I suppose... Does anybody have a dead simple answer to what could be causing this? And if it's not a dead simple solution, does anybody have a ball park figure of what a dealer might charge to fix it? I've never had dealer work done, so I'm kind of going in blind. As always, THANKS in advance!!
  12. I just sealed up my exhaust today with silicon sealant. However, when I turn the engine over slowly and hit the compression stroke (mid part of the kickstart cycle) I hear a quick hiss noise. It sounds like air being released somewhere. Is this the carburetor pumping air into the motor or do I have an air leak somewhere? It's really confusing and worrying me. It only happens while the exhaust is plugged. P.S I can't hear it when the bike is running it only occurs at this point while turning the bike over.

    HELP! What is this sound??

    My friend bought this 2012 TE310 with 3500 miles on it. It looked to be in good condition when I went with him to check it out, he got it home and has done about 100 miles on it running perfect and all of a sudden it quit when going down the highway. It would still start when he pulled over, but was making an aweful sound. Im not too familiar with huskys, so all I had checked was the oil when we got home to see if there were any shavings or anything in it. It was pretty low on oil but has nothing in it. By the sound of this video could someone point me in the right direction to what to check next. We are done for the night and I figured I could hopefully get some insight overnight on here.
  14. Heres the noise. Sounds like its coming from my top end..,

    High RPM Scraping Noise 2011 CRF250x

    I have a 2011 CRF250x, I've always been on top of maintenance, never really flogged the bike. From about this time last year the bike developed a sort of rubbing/scraping noise coming from the left side of the motor only when it was 3/4 throttle or more. I thought it might have been drivetrain so I pulled over, put it in neutral and did the same thing (3/4 throttle and more) while sitting still and it did the same thing. The bike sat in the shed for about 6 months and then I took it out to see if I could figure it out. I pulled the valve cover off and everything seemed normal, nothing loose, valves still in clearances. I also pulled the cam chain tensioner out, I wasn't game enough to go further so I put it back together and started it. No noise. It was fine, I rode it for about 1-2 months with no noise at all. I had to get a friend to ride it to get it inspected for road worthy and the noise is back. I've tried taking the cam chain tensioner out again and it hasn't worked this time. The noise has also become worse and at lower RPM (more like 2/3 throttle now). I'm wondering if this has been experienced by anyone else also and how they fixed it. I'm not game enough to continue riding it as I'm not sure whether the noise is something going bad. I'm keen to fix the problem as I've been without a bike for so long, I just don't have the money to pay someone to dig around the bike for me. Thanks in advance

    Alright I have searched and have done research on forums before but have never posted. New guys get eaten alive, I don't mind just help me out. I have an 05 yz250 that runs like a champ, well I came across a 2015 yz250 that I couldn't pass up but she don't sound right to me. Got it to the house, fires up, idles correctly, and revs smoothly. Little bit about the bike, it has a fmf fatty with the Q slip on that looks like a four stroke pipe, but no other real engine mods. At the top of the power band the bike sounds as if the power valve is loose or there's maybe a slight piston slap. I have had a bike with piston slap and it doesn't come to me as that. This is where I need your help. It does the loud cackle noise at the top of the band, then falls smoothly back into the power as it revs down some. Also when down shifting to bring on the power it makes a slight delay with a weird sounding small pop(kinda like a back fire, just quieter). Any help before I open this thing up would be helpful!!!! Thanks in advance ✊🏼

    2015 kx250f problems

    Hi guys any response would be great. So I just got this 2015 kx250f like 3 weeks ago and I haven't got to riding it that much but since then I've already noticed a few things that are a little abnormal. Whenever the bike is warmed up or even ridden for a while the clutch seems to be jerky and not smooth when taking off from stop. what could be causing this jerkyness? I've replaced the oil in the bike and adjusted the clutch line, nothing helped. When the bike is rolling I can shift the bike into neutral but not when stopped (while the bike is running of course). Also the one that is really concerning me- whenever the bike is cold started(and idling), idling( when warmed up) or cruising in low rpm and trying to accelerate I hear this knocking noise. But whenever I'm revving the bike just a little bit all the way to high rpms the noise seems to go away. It doesn't loose any power and it's only at really low rpms. I can confirm it's coming from the engine and not the chain since I've adjusted the chain to spec. Thanks in advance

    2003 KTM 125SX noise?

    I just bought a 2003 KTM 125 SX from craigslist the guy I bought it from only owned the bike for a couple weeks but the guy who owned the bike before had supposedly just rebuilt the top end, I also believed he probably raced with it cause hes got his name on the decals and numbers on it. When I went to pick it thought it sounded fine but I'm not familiar with 2 strokes and I showed it to my Dad and started it up and he pointed out a noise that sounds kind of like a rattle or something and I'm not sure if that is just a normal noise for this bike or if there might be an issue that I should look into. Also the bike looks really clean its got a new fmf pipe on it and supposedly new boysen reeds but the day I brought it home I went ahead and did an oil change and it was verrrry dirty. If anyone is familiar with this bike or has any advise I would really appreciate it!!! Thank you!! Here is a link to a video of the bike running
