2011 ec200 marzocchis

My throttle side fork slides over the axel even if its tightened down all the way. i have tried a new axle, no change. So in the meantime I have been using alumn. tape around the axel to shim it, but thats clearly a temporary fix. Anyone have any ideas? Should i contact marzocchi and try to get a new fork bottom? should i find a machine shop that can put a permanent shim on the axel? or should i look for a used set of forks due to the unknown horrors my forks may have in store? I also have no idea how it happened, only noticed it after i brought the bike home

45's or 48's ?? Race or sixday's model?

I think you should contact Marzocchi. That's not common.

When you say "tightened all the way down," are you saying that the gap at the front of the "fist" is completely closed when you tighten up the bolts, thus preventing ANY further tightening?

If not, then it could be that the bolts are too long therefore binding on the bolt's shoulder before the gap is closed enough for the fist to bite on the axle.

Its the six days model. The gap is closed all the way. i was going to try to shave some metal in between the gap but thats probably a terrible idea. The weirdest part to me is that its only that side. the rotor side has the correct gap, so that rules out the possibility of previous owner forgetting to tighten the axle down and it spinning inside the clamp and loosening it up. Maybe the previous owner didn't know what he was doing and used a torch to heat it up the clamp to get the axle out?

How much play are we talking here?

We're talking sliding the axle in and out of the clamp with the gap fully closed. i have already tried a brand new axle from gas gas and same deal. without putting the front wheel on i put the new axle in the clamp without loosening the pinch bolts. if i push the axle through the throttle side clamp with no gap there is not a single point where the axle will stop sliding. i forgot to mention there are no stress fractures or breaks whatsoever in the clamp.

At some point, the pinch bolts were over tightened.

You can take a hack saw and "widen" the gap just enough to get a good purchase.

Is it somehow possible you got an older wheel with smaller axle?
I cant imagine any way that you could max out the pinch with the correct axle
