| I can get the eccentric in the right position but not with the chain on the sprocket. Am just about to ring for a new longer chain I fancied a nice gold one anyway! Honestly though I have tried and tried to get some sense out of it and cant. Its almost as if my chain has shrunk! Maybe fitting a 180 rear has made the problem more noticible than when I got the bike with a half worn 190 on.
JPM, when I had the fork seals done as far as I know he did nowt else to the bike. I've never been 100% happy with the way the bike felt handling wise since I got it. I never seemed confident in it the way I was with my 996s a few years back. It feels as if the front could wash out when tipping in to bends. Could be down to the rear height being too high as the eccentric is very low down in its chain tensioned position.
There are only 2 positions the eccentric can be in to have the chain at correct tension. One is horribly wrong as it causes the chain to be hard against the lower swinging arm and also the wheel to rub on the hugger. And the other is the right one. When in the correct position the action of tensioning the chain actually decreases ride height as the eccentric is going anticlockwise from the 5 oclock ish position.
I cannot see any other way but fitting a longer chain. I'm hoping an extra 2 links will be enough? Suppose it makes sense that 2 extra links will lengthen the wheelbase by the amount of 1 link of chain. Wondered about 4 extra but that might mean that after the chain has stretched a little there would not be enough movement left in the adjuster to take up tension? Then I would have to fit a bigger rear sprocket to compensate. Which might not be a bad idea!  |
