RIP EXUP!

[Andy W]

All things must pass..  :'(


A few hours spent trying to get the EXUP valve to operate but it must be slightly warped - cleaned it all, copper greased it all as I always do but this time...nada!


Removed it, blanked the hole in the mounting plate with nut/bolt/washers so running on full bore now!


I wonder how many other Fokkers are riding likewise?

If it's warped it can be straightened.  Not difficult, just have to be patient and careful.  Might need a few goes to get it right but use a straight edge to eyeball the spindles and gently bend it back in line.  Grip one spindle in a vise and gently apply pressure with your hand.

Much better to have a working EXUP than an empty one.

Super easy, I straighened my by placing it in the chuck of a drill, slowley rotated it to see which way it was bent and hit it carefully with a rubber mallet, did this untill as far as I could tell the valve was straight. Then flipped it around and put the other end in the drill and did the same again. End result, pretty straight exup valve.

Or just take it to a machine shop, it will take them a few minutes and they will be able to get it dead straight with within a few fractions of a milimeter.

I'll give it a go......unless I set fire to the damn bike first....after a run of problems & lots of £ spent I am currently broken down at side of road at 7.00am waiting for AA...total electrical failure! 🤯🤯🤯

Oh bugger. Sorry to hear that Andy.
Hope you get sorted quickly and it’s something simple. 🤞

5 hours tracing & testing electrics for a fault that took 4 mins to fix! 🤬
Oh well, at least I'm back on the road!


Also - fixed the EXUP - a vice, heat gun, straight edge & a hammer did the trick! 👍😁

Fantastic, glad you’re back on the road and got the EXUP valve sorted. Out of interest, what was the electrical cause?

My Exup seized a long time ago, the bike still runs fine so I'm not bothered   Although I think my biking days are coming to an end, I rarely use it any more
