Head shake when I let hands off the bars
 

Hey guys, I got a 02 GSXR 750 and when I let off the bars if it not set on cruise I get terrible headshake. The bike nearly goes into an all out tank slapper! What gives? I had the tire balanced when it was mounted...could this be a twisted fork or something? It went down once but not that hard. This really is irritating....even made my stock damper shoot the shit. Anyone have any ideas to the cause of this?

Check your sem bearings to see if they are loose. Later:apimp

your head bolt could have some play in it, could be from a bad tire also.

tighen up your head bolt really tight, if it isnt that, Its gotta be something else.

My bike does the same thing, at about 50+ miles an hour its kinda bad, I am still running the same front tire I got with the bike since it was new, 7000 mi so it may be the tire.
