Been about 25-30K since last swapped chain (and yes, front sprocket nut swapped then too). Not got too much slack in it, but it's developed a couple of stiff links and has a spot of surface corrosion. I keep cleaning and lubing it, but they keep sticking and I'm feeling a duff-duff-duff-duff as I got down road. Especially when I'm on the throttle, and seemingly changing frequency with change of speed. Since having this, I've changed rear wheel (disc bolts were seized!), new rear bearing and tyre - so can rule them out. Front end feels alright, nowt obvious wrong there, so fairly sure it's the chain. It does seem to ease off when I really lube the chain up.
So reckon it's probably time for new chain. Got a DID VX on there now, debating whether to go same again or splurge a bit more on a Extreme ZVM-X (extra £40 ish) Worth it? Anyone tried one? Last much longer? Or just not worth it on a nice smooth inline four like the Fazer?
