On Quick Deceleration Tire or Belt Barks
12/25/09 at 06:04:16

I am sure you guys and gals are tired of hearing about my noises. Hope this is the last one. When I let off the gas I get a kind of bark sound which my mechanic thinks is the belt or the rear tire. It will not do it in first gear, but does in the others. I think this new sound appeared after the mechanic installed the Verslagen1 cam chain tensioner. The new tensioner stopped the annoying cam chain noise I had before. If you have any ideas including belt too loose or tire actually slipping on deceleration, please present your comments....Thanks, Dan

Re: On Quick Deceleration Tire or Belt Barks Reply #1 - 12/25/09 at 07:04:55 1st seems like the most violent gear to decel in. So, Im surprised it doesnt do it in first. Id have alook at the front pulley & then try to figure it by the sound, front or rear? A passenger might help you find it,

Another idea came to my mind...Do you suppose the sound could come from the dampers in the rear pulley? Just a guess....Dan

Have you thrown out the "belt tensioner" tool and checked your belt tension by the twist method yet? Tightening the belt fixed a noise on mine.. it was more of a squeak than a bark though.

(pssst ix nay on the azy kay) Check the nut (pardon the expression) on the drive pulley. When it gets loose the pulley can work back and forth.

That was my second guess, but Id check that pulley, because it can cost $$$ if it gets too loose.

Can you get someone to ride w/ you & listen? Might be able to figure better where its from,

I thought about moving the bike back and forth in the shop and watching that pulley for improper movement. Think that would produce any helpful information? THANKS TO ALL.....Dan

This technique works great with a chain drive bike, but I never tried it on the Savage.. make sure the belt is tight first.

Which way loosens the pulley nut? Probably clock wise to loosen & counter clock wise to tighten. Would it be safe to use an electric impact wrench to loosen or tighten it? My impact wrench has no adjustment for impact. Wide open all the time, I think. I may have an air powered socket wrench as well. I will have to look.

As far as installing a Harley muffler....I sure would like to do that, but I am constrained to stay within the law. Legal, you know. That is part of my life as a Christian. In past times I have tried loud mufflers on my Sportster and Honda Rebel only to get them off as soon as possible. Too loud for me, yet I would like a little more sound out of my S40. It is so quiet, how can it even be up to the sound level limit? Thanks again all.....Dan

I doubt the threads are left handed. See this post by JOG as to why. I am away for Christmas but will return home to my shop manual this evening.. will try to remember to look up the correct rotation and post if no one else verifies it for you. Obviously you want to make sure of which way to turn the nut before taking an impact wrench to it, but since you have one, it should come off easily by holding the brake and using very short bursts of the wrench. There is also a "stick a broomstick against the pulley" method but I would save that as a last resort.

I think it's the clutch on the other side that's reverse.... I had a friend come over and hold the rear brake while sitting on the bike... otherwise,... you might stick a broom handle through the rear pulley spoke and let it jam against the swingarm?...
