Its me selling the bkool pro on
ebay for £220,
Adam, small world, but to be honest £220 is too much of a risk for buying something that perhaps is 'broke' and incomplete.
A complete new Pro can be purchased for £359 from
Wiggle.
Edit: Just noticed your selling the stand for £120 so the whole thing is £340 just £19 of the Wiggle new price complete with warranty etc.
From my experience with my Classic the nut that holds the flywheel on the shaft is threadlocked with a permenant threadlock and removing it can damage or even destroy the threads so to get it off you have to split the nut.
The flywheel has no key so it can be installed at any rotational alignment point on the shaft and the shaft is just that a straight rod with a thread on the end so any rotation of an unbalanced flywheel would have no impact, the shaft could even be bent.
The flywheel is a very solid lump so I would be suprised if any amount of heat generated would warp it without the surrounding plastic being melted.
What can make a lot of noise it the magnets vibrating.
The plastic fan attached to the flywheel could possibly be fouling.
All of the above is is easy to check if you have a set of 12 point screwdrivers or small allen keys.
Just turn the unit upside down and undo the six or so screws that hold the two bits of casing together and once you have the the top half of there are two more at the front that hold the bottom half on.
Once that is all off you will be able to see if any thing is warped, broken, loose etc. You can even run it like that to check if the nosie is still there. Try it with the power off as well if you wish.
One last thing is to check that the threaded brass drive screw that moves the magnets is firmly engageed at the front where is sits in a small plastic cap/bearing which in turn sits in a socket in the main body. If the cap/bearing is missing the drive screw will be free to move and may cause the magents to vibrate more.
