Strange things happening to my Chain

So I'm finally ready to take my bike out of the garage since the temperature is below 100 (still above 90 though ) and as I take it out on my test run after changing all the fluids I notice this fast fluctuation in RPM's, about 250, that really gets noticeable above 10k.

I need a new chain so I go to check it, make sure it's nice and lubed and to the proper tension. Here comes my problem and I think the cause of my crazy fluctuations, half my chain is loose and the other side is tight, normally I wouldn't think twice about this... it's always been a little like that, but now it's like one side the tension will be around 20mm and the other around 55mm.

Any ideas?? I've never let my bike sit for this long but the summers here in AZ are unbearable, did I do something wrong?

let's see if I can explain this a little better... when you check the slack on your chain you do it at one place right... about mid way between the rear and front sprocket on the bottom... it's right there I get two entirely different measurements.



make more sense?

I'm thinking that the chain didn't wear right or it's just completely gone anyway... it has about 22k miles on it.

that exact same thing happened to me as well. i had the rpm fluctuations, (felt more like the bike was stuttering on/off successions real quick) the difference in chain slacks all the above.

took it to the mechanic and he said the rpm fluctuation was due to the chain being tight and loose (a "stretched" chain) he said and that it needed changing. needless to say i changed it asap (mech said it could fall off any second...no masterlink) and all my problems went away

Get a new chain. 22k is way overdue, especially with the temps that you ride in over there.
