While my CARC gently weeps...

Hi all,
It has been some time, I know. I have an early (2008) 8v Griso that I love riding, but has been nothing but problems.

I have been struggling with CARC issues for a while now, on multiple units. I have two CARCs that I seem to keep swapping for service.

I now have my original one back on, 36k miles, and it leaks It started leaking for the first time probably around 15k miles. At the end of a ride, there is oil flung out everywhere around the rim. The breather is not plugged, it's not coming from somewhere else, although there was an issue with a leaking boot too.

But after changing the seal and it still leaked, I began to wonder. Turns out, my bike has about .020" of play at the wheel rim, most noticeable at the 12 o-clock and 6 o-clock positions, which to me, indicates bearing wear. Obviously, bearing wear will take out a seal.

Does anybody know a spec for play? I'm afraid to ask what the factory says is OK. We all know what the factory calls OK...

Cheers and thanks,

There was an issue on earlier units with the large bearing. Just replace the bearing and seal, or have them replaced.

A very long shot but check for a hair line crack running from the wheel bolt thread out to the seal area on the hub. It will be very hard to see.
I think it took 3 brand new seals before they found out what the problem was. Still have it in a draw as a reminder.
