Wierd Winding noise

[quadgod440ex]

Ok fellas , i searched a few threads and didnt come up with anything. This might sound stupid but when im riding there is a winding noise comin from my bike almost like a supercharger or something. like i said might sound alittle stupid. But that is the best way i could describe it. Its only when the bikes in gear and im riding. I have no idea what this is... Possible Clutch?Trans problem? Im not noticing any shifting problems or clutch slipping problems . Has anyone had this problem before?

Check your motor mounts. When one of my motor mounts on my trx250r cracked in half it made a similiar noise. If not its probably something in the motor?

tires lol... alot of old cars trannys wine from the type of gears there made of.. i cant imagine the clutch winding unless the throw out bearing is fried, but if it when ur riding thats ruled out... can def be a trans problem for the most part... try this when u start riding pull in the cltuch and let off the gas and see if the sound is still there and than re engage the clutch try to spot a difference... also drain ur tranny oi and check for anything wierd..

Does the engine still rev and preform the same?
Noise change under a load?
Ck the oil filter for any metal...
May be crank going bad!

Hope not!!

is it whining? or wining, winding. That sounds strange to me lol.

Lumi: the trannies whine because they have straight cut gears instead of slanted ones. Something like that, I know it's the straight cut gears though

quadgod440ex: check your chain, filter?, ummmm lol.

describe when it makes the noise, EXACTLY what is happening at the time.

yea I no what your talking about and now is your bike brand new with HRC cam because mine did that when I first got it but thats just my 2 cents

[quadgod440ex]

Motor runs great , Trans shifts fine , Clutch does not slip at all. I was also thinking about the straight cut gears , cause when i had my car trans built with straight cut gears it did this. But i just never noticed it on my bike before. Ive had it for almost 3 years now and it just came to my attention. when the bike is idling and i rev it , the noise does not happen. It does NOT happen when i engage the clutch. The problem only consis once i am riding in a gear. Does it in all gears. Change my Motor oil after every ride , and my trans oil every other ride . I have not noticed anything different in the oil , No metal shaving or debri in them. only way i think a chain would do it is if it was way to tight. Chain is fine. Tires are brand new holeshot mx6r's , noise also accured with other tires. Its just a really wierd whinding noise. The bike is performing the same i havnt noticed anything at all different. I mean maybe theres nothing wrong maybes its just something i really never noticed. Only thing i can think of that might give u guys a better explanation is i noticed the problem After i took the bike out the next weekend after a really muddy muddy muddy race. Thats the only other clues i could think of. Thanks so much for all the input. Sorry i cannot describe the problem better.

sorry i do not have the hrc kit. Mods are in my sig. Thanks

Like asked above, if you pull in the clutch while ur moving and just drift does it still do it?

Still sounds like a trans problem though.

I havnt got a chance to go out there this morning. Im actually at work right now , when i get home i will take it up the street and see what happens. Thanks

do you have a airbox lid because if you dont that noise might just be the filter sucking in more air

my friends yfz doesnt have a lid but has an exhaust, KandN , rejeted, and when you slowy start out you hear a whistle noise like a turbo but when you gas it you can only hear that exhaust

[honda4life72]

nah is just your transmisson winning , mine does it to

[quadgod440ex]

ok what i came up with is ....... When i pull in the clutch and rev it , The noise does not happen. the noise only happens when i am letting the clutch out to go. So im pretty much leanin towards the clutch is glazed or something. Not positive. Gonna check it once i buy a new one.

time for a video to even more specify the issue.

[hondamano4]

is your chain and spocket good and oil .because when i dont do mine for it in long time it start make something like that and it coming from my front spocket. when i oil it goes

Oil Gets changed after every ride. Chain and sprokets are about 2 motos old. just changed them for the new season. Im thinkin some how the plates are glazed or something cause it is only when im takin off. once i get goin it stops . When im rolling if i pull in the clutch it does NOT make the noise. so im leanin towards more of a clutch issue. Its only when im slippin the clutch to leave. Lots of good ideas you guys have tho. Thanks alot i appreciate it!

[d3ktrix]

Makes sense by what you have said.

Deff. internal tranny/clutch.

what carb you running ? the fcr carb has a whine like a gear drive, after you take the air box lid off it is even more pronounced.

just a thought.

[quadgod440ex]

Stock carb
