Guest justice1327 Posted June 9, 2013 Share Posted June 9, 2013 I just did some mxs on my VFR. Lowered the bike by rotating the triangle one hole to the right from the sprocket side. Oil change, changed coolant to Evans, lowered front forks by 10mm, installed new pegs and adjusted pedals. Put the bike up on its center stand to do one last ops check and once over. Decided to put it in gear and wax chain. I noticed it was making noise and jumping. Chain is tight, but has some slack. Bike and chain have 6K miles. Waxed every 5-600 miles. You can see it and hear it at the link below. Any help is appreciated. Not sure how this site works, but i hope to get an email. Otherwise, I will just check back.

Member Contributer CSFS Posted June 9, 2013 Member Contributer Share Posted June 9, 2013 Sounds like a siezed link or two somewhere in there... Rotate by hand and visually check, could also be a worn countershaft sprocket - how many miles...???, how old...???, service history of the chain...???

Auspanglish Posted June 9, 2013 Share Posted June 9, 2013 Hey there... Firstly, in first gear it's quite common for the chain to do that... I usually use second gear... but be extremely careful there are no dogs or children or unaware people around that might knock the bike rocking it backward and the rear wheel come into contact with the ground because your bike will launch forward... and don't dare get your fingers or hands anywear near a rotating chain. Secondly, if you click on the "follow this topic" button up the top right, you will receive a message advising you when new replies come up. Also that chain looks real tight...

spud786 Posted June 9, 2013 Share Posted June 9, 2013 Usually you can see a Bump in the chain as it rotates around the rear sprocket, I didnt see that as in a frozen link. Maybe the cs sprocket is worn bad enough to cause a mismatch. but its all related something with the chain and sprockets isnt right. BTw chain wax freezes up the whole chain and everything doesnt spin freely Link to comment Share on other sites More sharing options...
Guest Posted June 9, 2013 Share Posted June 9, 2013 On the Utube video it states the mileage and mxs of chain, but I was unaware the site would post the actual video and not take you to the video as it appears on Utube. I posted the mxs and mileage of the chain per the recommendation. Auspañol...sound like your speaking from experience. Actually, the gear was in second as first gear is so bad with the noise and chain jump I was afraid it would shift the bike b/f and it take off w/o me. Another site said to adjust chain at tightest spot. I think I will rotate the chain slowly all the way around and find the tightest spot and be sure it is w/in specs. Thanks all. Any more suggestions are welcome. Link to comment Share on other sites More sharing options...
Audigier Posted June 9, 2013 Share Posted June 9, 2013 It sounds like the chain is too tight and when mine did that it was already toast. How old are your sprockets? Link to comment Share on other sites More sharing options...
Member Contributer BusyLittleShop Posted June 9, 2013 Member Contributer Share Posted June 9, 2013 Your chain is slapping the top of the swing arm... its possible you maybe running too much slack... check tension... Link to comment Share on other sites More sharing options...
Baileyrock Posted June 9, 2013 Share Posted June 9, 2013 I agree with Auspanol's thought,s on over tight and common slapping noise. What brand chair? I've toasted brand new (cheap) chains in less than 2400 miles. BR Link to comment Share on other sites More sharing options...
soichiro Posted June 9, 2013 Share Posted June 9, 2013 Chain looks way too tight to me.I'm pretty positive. I don't like that noise, that's not good. I hope it's just the chain and sprockets. The bottom should be slowing slack will running like that. I mean obvious slack.Slapping is normal, the chain never has to deal with full shock extension while riding.That popping is not normal. Do something simple for me. Place your fingers vertical and tell me how many fingers fit between the chain and bottom of the swingarm. DONT RUN THE BIKE TO LUBE THE CHAIN MY FRIENDS. IF YOU EVER SAW A HAND THAT SLIPPED AND WENT THRU THE SPROCKET YOU WOULDNT DO IT. WE HAVE A CENTERSTAND, JUST TURN IT BY HAND. PLEASE!!!!!!!

Guest Posted June 10, 2013 Share Posted June 10, 2013 Thanks for the info...some say too loose, some say too tight. I KNOW It is not loose...I measured the tension and slack...less than 3/4 of an inch of verticle movement. Manuel says 1 -1 3/4. I set it w/in these perimeters...still got the same noise...not sure now what it can be....bent sprocket is my guess. Chain is simple to change and so are sprockets...I will let you all know what I decide. Still appreciate any inputs. Link to comment Share on other sites More sharing options...
spud786 Posted June 10, 2013 Share Posted June 10, 2013 If you have 3/4 inch on the center stand it will be even less with swingarm level, looser side is better than tight side, when it comes to stressing the chain. Link to comment Share on other sites More sharing options...
Baileyrock Posted June 10, 2013 Share Posted June 10, 2013 Also check chain slack every 1/8 rotation of the wheel, see if it changes (gets tighter/looser). Indication of a stretched chain. It could have 3/4" in one spot and 2'' in another. BR Link to comment Share on other sites More sharing options...
Member Contributer BusyLittleShop Posted June 10, 2013 Member Contributer Share Posted June 10, 2013 Chains that are too tight hum... chains that are too loose either slapthe swingarm or chain guard... you can eliminate the noise by pressinga rag up from the bottom of the chain while it is running this workslike a chain roller... The purpose of the chain roller is to take up the slack generatedafter the swingarm is lower during ride height adjustments... Thelower the swingarm is adjusted the more slack appears in the chain...instead of suffering excessive chain slack HRC added a roller... withthe chain resting on the roller less slack is felt through thethrottle during on off transitions... it works a lot like a chainroller on a dirt bike if you will... in fact I employed a ball bearingdirt bike roller purchased at a cycle accessory store...

BLS, nice mod but please, don't encourage folk to get their hands anywhere near the chain and/or sprockets with the bike running!! That be scary chit!!

Veefer800Canuck Posted June 10, 2013 Share Posted June 10, 2013 Someone on the old VFR "big mailing list" got his hand sucked into the chain/sprocket with a rag. Severed his fingertips right off. Google image search Seajay VFR chain if you really wanna see it. It's not pretty. Link to comment Share on other sites More sharing options...
Audigier Posted June 10, 2013 Share Posted June 10, 2013 I only run the bike on the center stand to spray the lube, turn it by hand to clean it with a brush Link to comment Share on other sites More sharing options...
Guest Posted June 10, 2013 Share Posted June 10, 2013 Thanks everyone for the inputs. 3/4 was with someone of my weight on the bike. I wasnt aware of the chain roller and I believe I will look into that for this and my other two chain drive bikes. I have adjusted the chain and it is now 1 1/2 with someone on the bike. ... but it still makes the noise...just not when I am on it riding it. I will keep everyone posted. Thanks again.

Auspanglish Posted June 10, 2013 Share Posted June 10, 2013 You don't adjust nor check the chain tension with someone on the bike. Manual states the bike is to be on centre stand and rear wheel free, off the ground.. 2.5 - 3.5 cm of slack under the above circumstances. Link to comment Share on other sites More sharing options...

Manual states the bike is to be on centre stand and rear wheel free, off the ground.. 2.5 - 3.5 cm of slack under the above circumstances. My thoughts exactly. Never heard of checking slack with the bike weighted. Chain will be at it's tighest point when the swingarm is in the center of it's stroke. Dont agree at all that the sprockets are damaged with only 6k miles. Chain is too tight and could have some bad links. I dont know how your bike is stored. It's possible there is 1 or more sections seizing. The best method to ck chain wear is pull the chain directly rearward at the sprocket in the rear. pull the chain towards the rear of the bike. Directly where the chain is in the middle of the sprocket. When new it will pull off the sprocket a very small omount. When worn out it will pull far enough back to see the whole tooth on the sprocket. As stated check this in many spots. You stated you lowered the bike. Thats an unknown variable.

Guest Posted June 12, 2013 Share Posted June 12, 2013 Hello, I never clean, adjust, wax or get my finger near a moving sprocket/chain. ( I have 25 yrs of mxs and electrical background. I dont even wear jewelry) With regards to the measurements I took after adjusting the chain with someone on the bike It shows that with 3/4 of an inch FREE play it was NOT too tight as some had suggested. Same with the most amount of free play at 1.5inches....that measurement would be the most free play one would run. BOTH settings caused the noise. These show that while the chain is set just right and to the most loose setting...it still made the noise. So it was not the tension on the chain that was causing the noise. So what was the problem you may wonder.... I went to change the sprocket/chain set and noticed the drive chain guide plate was snapped in half. I have no idea HOW, but I changed it obviously. No noise with stock chain now. So I kept the new DID 530 chain for later. Thanks to everyone. Link to comment Share on other sites More sharing options...
