nklr torque wrench needed?

[Weaver, Mark]

you are correct about the chain slack changing. i hope i didn't accidentally give the impression that i thought otherwise. obviously, if it didn't change, you wouldn't need to have slack. the reason for slack is so that at some point, as the swingarm goes through it's travel, the chain doesn't get too tight. chains actually don't need to be slack, they just need to not be too tight. since most bikes don't pivot at the countershaft, this means a compromise of sorts. i believe (someone say something if this is wrong) that the chain is slackest when the suspension is topped out. assuming this is the case, then adjusting the slack at any other setting would simply result in a too-loose chain, which is probably no big deal as long as it stays on. i can't imagine how it would possibly be better to adjust the chain slacker with more load on the bike. the swingarm's path remains the same. it is still possible to use all 9" of travel, regardless of any reasonable load on the bike. as such, it seems reasonable to me to adjust the chain slack to be the same under the standard conditions (bike on sidestand, unloaded) no matter what you plan on putting on it. carrying more weight does not affect the maximum chain looseness/tightness because it does not affect the limits of the swingarm movement. if it were possible to get the chain too tight with the factory slackness spec, then the factory spec would be different, eh? i aplogize in advance if anyone finds this too pedantic. -mark "protractor" weaver

Four inches from lowest point to highest point, measured at the rubber chain wear piece, sounds just about right to me.  If you use lots of WD you won't have to adjust very ofter, has been my experience.

I'm 170 lbs and getting heavier...
