vocab Posted February 4, 2019 Share Posted February 4, 2019 Hello all!So i recently fitted a new drive chain and sprocket set, insuring to the align the rear wheel, properly lubricate the chain and maintain the correct amount of chain slack. However, whenever I release the throttle a strange slapping / loud clicking noise comes from what sounds like it could be the chain. The faster I am going when i come off the throttle, the louder the noise is. Whenever I apply any throttle, the noise is none existent.What would be some other potential causes of this and what would you propose to be a good course of action?A little note that might be useful, the replacement chain was somewhat smaller than the original. I had plenty of free play in the rear wheel/swingarm adjusters but it did mean that when i moved the rear wheel in, the drum brake was forced to rotate slightly. There's a supporting bar holding the drum brake in place alas rotation was necessary.Hopefully someone can get a good grip on what i'm describing, first time posting here so sorry it's a bit wayward.Warm wishesGabe Quote Link to comment Share on other sites More sharing options...
rennie Posted February 4, 2019 Share Posted February 4, 2019 Hello and Welcome It sounds like it's too tight or too slack to me!but it's hard to say without seeing/hearing it Quote Link to comment Share on other sites More sharing options...
Tiggie Posted February 4, 2019 Share Posted February 4, 2019 It does sound like the chain tension is incorrect like Rennie said. Quote Link to comment Share on other sites More sharing options...

Tango Posted February 4, 2019 Share Posted February 4, 2019 Welcome to TMBF mate. .........sounds like it's the wrong chain for your bike......I'd get onto whoever it was that you got it from and get a replacement. .... Quote Link to comment Share on other sites More sharing options...
fastbob Posted February 4, 2019 Share Posted February 4, 2019 Hi and welcome, make sure one of your rear sprocket bolts hasn't worked loose and is hitting the chain guard . This happened to me recently and I could only hear it when I throttled back . Do you mean that the new chain has less links or do you just mean that it isn't heavily stretched ?

Westbeef Posted February 5, 2019 Share Posted February 5, 2019 Also worth noting chains 'bed in' and will rapidly elongate in the first few miles. So you have have had the correct tension set and now it's gone a bit slack. Quote Link to comment Share on other sites More sharing options...
