yeah, i had to remind my indie tire-replacer guy about proper chain slack on my former bike, an 09 ninja 650.Make sure you triple-check this if you have a shop do any work -- they often set it like a streetbike chain.
There's a device called Chain Monkey that they highly tout. Never used it as it is pretty simple for me to use a tape measure and my finger. I'd be interested in hearing from someone who has used it.Anyone thought of a go / no-go gauge for chain adjustment? What do they use in the pits for motor gp?
So I'm curious why several of y'all make note not to trust the marks.
Seems if the manufacturer can drill holes that match so the bike can be bolted together should surely be able to make marks that match.
What do you use if not trusting the marks?
On modern bikes, manufacturing is a lot more consistent and I've found that the marks are usually very close or dead on. I'm fairly comfortable trusting the chain alignment marks on the swingarm on any bike with fuel injection.
You still want to be careful to make sure all the slop is out of the system and stays out as you tighten the axle. I usually bump the axle ends with a rubber hammer to make sure the axle and hardware stays all the way forward.
