| That sounds about right. The bars will flop to the side and with the caliper being heavier, it makes sense that it would go that way.
There should be no play or rattle but the bars need to turn freely like that |

| I saw a video of a mechanic showing how to diagnose loose head bearings.
Jack up the front of the bike and let the handlebars drop to each side. If it goes "clunk" and stops, its good. If it goes "clunk", bounces off the stop and then falls back to the stop, its too loose.
CLUNK = good
CLUNK, clunk = too loose |

| The video showing the 'bounce' test for head bearings is here:

He's a VMax mechanic/specialist, but the rules apply for the S'wing bearings.
When/if you repack your head bearings, be sure NOT to use Moly grease.

| I think you'll need to remove everything from the front. =( I don't have the book in front of me right now though.

| cheers for all the advice thanks for the bounce test sweendog yes you are right you have to take the front fairing of completley to access the 32mm nut on the stem.my advice for anyone doing the job which can be done with just removing the right hand storage compartment the handle bars.i took the lot of because i didnt have a 32mm deep socket when i mean deep its around 4 ins down the stem,so please go and buy the socket before you start the job makes the job so much easier.my bike handles now so much so i had a good set to with a ktm 690 duke for around 6 miles lets just say he wasnt impressed  |

Thanks for the tip! I removed the pocket to take a peek and found the assembly within reach. Now to do the bounce test and see about a socket. |
