Old Worn Chain clanking - Advice on urgency of the problem

[Chippertheripper]

The only reason I asked, is you wanted a recommendation on where to go. I'm pretty sure Jane uses a place in Westport. I'll defer to her:

WD40 is an expensive way to clean a chain, Kerosene is cheaper AND what most manufacturers recommend

if its not spinnin freeley and sprocket teeth are visibly worn replace and as allready recommended, replace everything

chains & sprockets last anywhere from 5000 to 60,000 miles or more depending on yer riding style, environmental conditions and maintenance

I run a scottoiler with ATF and a 530 chain instead of the stock 525 chain on my V-strom

front sprockets gets replaced about every 20k-25k, chain & rear sprocket every 45k-50k

I know, that goes against the recommendation of replacing everything at once

most people wear everything evenly, fer some reason, my ridign style, I chew thru front sprockets compared to chain & rear sprocket

i have always been told its bad to use and dries out the o-rings so i have never used it, i did some research on it and it seems its not bad to use, sorry for the false info, it was just what i was always told by more then 1 person

I use it as my only form of chain lubrication and I'm up over 26K on my current chain and sprockets.

its not that wd40 is horrible, its just not ideal really. fine to spray on and wipe off, but horribly expensive to do so. then again, its easy, and you'd have to set a spray bottle with kero, though kero works better, or diesle

wd40 I think is fine.

It has a light oil that evaporates and leaves a waxy deposit. On very fine mechanisms its not recommended because the "oil" has gone away and the waxy stuff holds dirt particles.

On a MC chain thats fine

The best would be rear end lube 90 or 120 wt high sulphur gear lube but it stinks and makes a mess

funniest part about mc chains is that they are smart enough to include a full coverage and often enclosed chain guard on scooters, but can't seem to make the leap that it would be good on full size bikes
