Hey, thanks all..  This one sounds like my problem:

A pain but fixable  8) Oh and b careful not 2 bash ur hands on the cut can  ::)

Yeah, this sounds plausible..  Im going out shortly but ill de-assemble tomorrow and look to see if the new chrome has taken away the small "force fit" area.  If so, I have a Dremal so I can carefully remove the new chrome to this area without a coke can.

Will let you know how I get on..

ta,

Paul

Bugger!!  This did not seem to be my problem as there is nothing to remove, indeed, I need to add metal to stop the racer from moving:

Shows small amount of play at bottom:

Shows small amount of play at top:

Racer sits all the way down to the main ridge.


So, I have tried Racers from two headset and, two different sets of forks with all combinations having the same problem with a small amount of play.  Also, when I stripped my Firebird for chroming, I dont recal having to use any force to get the racer off so I expect this play was always there..

I have three other BMXs that I got assembled.  I guess during the week ill remove their forks to see if the racer has the same play..

Any thoughts??

ta,

Paul

Hi - shim what?  I cant see what surface to shim, indeed, I can see what parts of the tube should be thicker to give the racer a better fit but not where to shim.  Also, I have tried my two racers on a never assembled Aero Reflex and again, there is some play..

:(

Shim this bit all the way round:



 use a cut up Coke can (or soft/booze drink can of your choice), and cut a strip off from AROUND the can, not vertically on it. Cut to length so it fits all around the fork (or length needed to secure it), slide the race over, tap on and you're away :)
