Thanks for your help. I will do that and see what happens. If that doesn't work I will take it to a Yamaha mechanic. Need new break pads soon anyway. Noticed you are from North West UK, I am from Liverpool but now live in Australia. Anyway, thanks again for your help. Stay healthy!

yes, swapped like for like. Master link seems ok and yes, measuring between mid point of the 2 sprockets. Re my measurements, what I mean is that when taking measurements for chain tension, one section of the chain I get a measurement of 25 mm and in another section 36 mm. Hope that makes sense?

Hi guys. I have a 2016 Tracer, I just had new sprockets and chain fitted. Went with OEM front and JT rear with EK chain. When I went to pick the bike up the mechanic said there was a problem. There were tight spots in the new chain with a difference of 11 mm between loose and tight spots. This is the reason I changed the chain and sprockets in the first place! Interesting fact is that the difference in chain tension was also 11 mm with the old parts. What is going on here? I have read about possible causes such as sprocket not properly centred, tight master link etc... I have checked wheel alignment and its properly centred. Chain tension is 25 mm at loosest section and 36 mm at tightest. Not sure what to do and don't want to spend money chasing a problem if I don't need to. Any helpful advice gratefully received.
