Ok just got off the phone with the dealer.........
*According to yamaha it is normal, they have numerous complaints on it, and well aware of it
*The hydraulic mechanical tensioner is the same as last years R6, with slight changes to the ratcheting system.. the teeth for the R1 are pitched wider than the R6
*The mechanical part is responsible for setting tension and the hydraulic end will take up the rest of the slack (shock absorber)
*Yamaha is finding that, it takes longer for the tensioner to set and lock to the next tooth on the tensioner,(due to the wider spacing) that's why when bleed down occurs, it will back off and rest on the previous set tooth, this is when chatter/rattle occurs till the oil builds up enough pressure
*Yamaha claims it will go away once the chain stretches enough, so the tensioner can automatically compensate for slack and set itself to the next tooth
*Seems that my bike is in between stages, once it makes the jump the noise will go away when starting up. even after bleed down
(over night, extended periods of sitting)
*In closing... they are not going to change it,, just keep an eye on it, and if it gets worse, bring it back, and then we'll change it out.....FAIR ENOUGH but if it's the same as the R6 why not just give me that and call it a day... so you don't hear from my ugly arse again.. till of course for something major
from the replies I've been getting from members,, I'm going to assume that from 300-500 miles is when the chain starts to slow down on the stretch, so the tensioner is in limbo waiting for the chain to stretch some more so it can make the jump to the next level...
WE'LL SEE.... I'll report back with the mileage that the noise dissapears,, or that they replaced the tensioner
