Any tips/tricks for chain adjustment?
« on: August 17, 2007, 11:52:59 PM »
I've read the owner's manual on the subject (though I don't have a shop manual).  My chain tension is way out of spec, so I really oughta fix it before the next big ride.  

I already found this thread in a search, but are there any other pointers or helpful tips before I get into it — or just go get a spare cotter pin, suck it up, and start turning wrenches?

Thanks in advance!

Five vehicles for two drivers?  Sounds about right to me....

Since I haven't figured out how to check the slack while sitting on the bike (recommended check point) I use the centerstand and put the chain to the loose side of spec - somewhere around 1.5 inches.  The chain will be a little tighter off the centerstand due to the rotation of the swing arm.  Better to have too loose of chain than too tight.

The tip about using a screwdriver to pry the adjuster forward as you tighten the axle nut is a great one although I prefer to use a 14mm open end wrench.

Be sure to line up the rear sprocket with the chain/front sprocket - don't necessarily rely on the stamped markings on the swing arm.  When making the adjustments simply count the number of "flats" on the adjuster nut/bolt and apply the same number of turns to both sides.  One or two flats will make a big difference in chain tightness.

If you over tighten you'll have to loosen the bolts (again - count the flats and make them even) and bang the tire forward with your fist to seat it up against the bolts and begin all over again.

Have a spare cotter pin handy in case you break the original - I never could get them to last but a couple of changes so I went to a hitch pin.  Other than that - take your time and enjoy the process...
