Really doesnt sound like metal on metal. But it may be, thats just an observation.

Bought this bike last fall with 3300 miles. Bone stock. It knocks so loud I have to wear ear plugs. Has 6500 now...knocks horribly, but no worse than the day I got it. It cannot be normal engine noise. Its way too loud for "normal" , and its not a valve tick. Its a well defined harsh "knocking" sound which manifests when under a load only. Let up on throttle she's quiet as can be.

Its Not oil type, not detonation, not valve adjustment, not carb sync. Its all been done.

Riding with a crusty old jap bike rider today ... he said you have a bad cam chain tensioner. He said it sounds exactly like his Kawasaki 750 Vulcan did with the same problem.

He added a manually adjustable cam chain tensioner to his sled which fully corrected the problem.

Do you guys know if there is such a mechanism available for an 08 V-star 1100 ?? I absolutely hate riding it like this and I'm not having any luck finding such a thing via google. Seems it'd be worth a shot.

Many thanks.

Thank you. Good price on that piece too.

I'm gonna go remove them now. Didnt see anything in kb...but might have missed it. The 99's thru 09's (based on my reading) have a simple method of adding tension to the spring on the auto tensioner's. I'm gonna give that a whirl and see if it makes a difference.

Thanks again.

Nothing unusual found with timing chain tensioners. I bit the bullet and while running errands this a.m. stopped at a yammy dealer. Had the service manager listen. He said he hears nothing out of the ordinary. While I'm a bit surprised I'll take him at his word.

I guess I'm just not used to japanese bikes. To me it sounds like its going to blow up, and other riders always ask "whats that knocking" but I guess these engines are designed to be noisey.

I'll do what I've been doing...wear ear plugs and run it !! Leave it as is. I dont see it as a motorcycle worth sinking much $$ into anyway. So all is well.

Can you get a recording of it?
Well...I would say yes but I cant seem to find the charger for the camera I built a handlebar mount for. It has very good audio capability too...for a cheapie. I'll hope to find it when my daughter returns home Monday. She borrowed it and I have no idea where the hell it is.

Yeah a video might help.

I see you own a Harley with a twin cam, i do too. In comparison, the 1100 is much louder, might just be something that is normal.

Yea, thats what I'm beginning to think. Unfortunately there were no other vstar 1100's there that day. He wanted me to hear another.

Yes, The Harley is very quiet.

She (vstar)sounds beautiful when not under a load but when you load her down (not lugging) just with normal acceleration or even a slight up hill the thing just sounds horrible. The knock echo's when under an overpass. Its the loudest thing (by far) you hear when riding it.

I may try a second opinion when I get a chance. Hard to imagine its normal but I guess it is possible. Never had a motorcycle, or any motorized vehicle with an engine this noisy.

Thanks.

I don't hear anything like a knock on my 99'.. But maybe I'm not listening for the right thing? Have you listened to videos of other 1100s to see if they sound the same?

Nothing like you describe coming from my 06 with 24K miles.
But then again 'loud' is a relative term. What sounds extreme to you may very well be normal. Apparently your dealer thinks so. But if I were you I would find a couple more and have a listen just to satisfy my mind. That or swing by a different dealer for a second opinion.

I figured as much. Anyone that has ridden a motorcycle would question this mechanical noise. Its all you can hear when you are accelerating. Several guys I've ridden with have commented on it, without asking them to. The service guy didnt ride it, he and I both just laid on the brake and slipped the clutch while revving..... To create a loaded condition which is when the knock occurs. Sure wish he'd have ridden it. You cant miss it when you are riding it. I could hear it when we were trying to create it, he didnt.

As stated earlier, the knock only occurs under a load, such as normal acceleration. When you lay off, or are in neutral, she sounds beautiful.

Oh...also......no its not an exhaust pop. It does pop but thats letting up and just on occasion.

Thanks, I really need to get that video but I cant find the camera / charger. Damnit. It would only take a few minutes.

I listened to the video a couple of times on my headset, I hear what you're talking about, but I also hear a lot of valve chatter. I have an 09' and I don't think mine is that noisy. But, now that I say that I'll get on it tomorrow and be wrong. I'm also wondering if it's not something vibrating against something that's causing that noise.. Check all of your windscreen bolts and make sure they're tight. Because it's possible that you've got something knocking (most likely plastic on metal) at a certain vibration. I only say this, because I would expect the knock to be present at the same RPM in all gears and I didn't notice it in first gear.. Only 2nd.. Is it present in the other gears as well? Try holding the windscreen while you're riding when it's knocking and see if it goes away? Just a thought.. Really hoping that it's not a mechanical issue for you.

Thanks Ego. Yes its present in any gear ...only when under a load. Looking back on it I should have loaded it down a bit more, but was afraid posters would accuse me of lugging the engine and it'd get off track. I hear you on the metal on plastic comment, but I just changed the wind screen (to a larger Cee Bailey). It is most definitely a mechanical noise. It sounds like a timing chain slapping on the plastic guide to me but I'm probably way off base....as usual !!

Thank you for your input, I appreciate it.

A good full-face helmet will get rid of that noise. :D
