It's the brake disk bolts that trigger the pulses for the speedo

another wee problem ,
i have tried to fit the back wheel with new sprocket , but the sprocket bolts are hitting the swing arm , i have noticed the sprocket seems to be thinner near the centre where the sprocket bolts pass through, making the heads of the bolts longer and hit the swing arm , any soloutions , its an ek sprocket with x ring gold chain, (chains not fitted yet),

also iv noticed a gap between the sprocket carrier and the wheel hub about 3-4mm is this the same on all falcos , iv never noticed ?

will post pics soon

It's because the disc is thinned out, I had the same problem, put some 2mm spacers between the disc and the shoulder to put the thread end in the original position.

the spacers would fix the problem , but dosent close the gap between the sprocket and the hub where lots of road grime will get in

I always spend a little more on the sprockets and get Renthal. Last longer than the pattern stuff (I've compared on the Falco: 12-18 months for the cheap cog, 18-24 months for the Renthal!) and the thickness is correct so no gaps for crud to get in.

looks like you're missing a seal on the swingarm side of the carrier, not that it will make any difference to the offset.

The spacer on the inside looks ok to me.

I'm in the middle of rebuilding one at the moment.

I'm not sure that the thickness of the disc and sprocket shouldn't make any difference as it's the spacers that give the overall length between the rear forks.

It's not the distance between spacers or anything like that, it is just that as the sprocket is thinner the studs stick out a couple of mm further (bloody italians doing things backwards) this causes the heads of these studs to catch on the weld.

By the way my sprocket is a DID and I had this exact same problem.

So is it as easy to fix as turning the sprocket the other way up?
