Author Message   Zxmarc Posted on Tuesday, May 17, 2005 - 08:14 pm:        woooohaaaaaa.. second gear.. 5000 rpm, coming out of slow corner on the gas... a few bumps in the road and my handlebars almost tore my hands off, must have shaken 10 times before it stopped... i just kept the gas on and held on. i am 6'2" 210 pounds... does anybody know a ballpark suspension setting for front and rear? thanks   Gentleman_jon Posted on Tuesday, May 17, 2005 - 08:17 pm:        what are you using now?   Zxmarc Posted on Tuesday, May 17, 2005 - 08:23 pm:        i would have to check... i got the bike last year but just started riding it last month... have about 100 km's on it since i have it   Gentleman_jon Posted on Tuesday, May 17, 2005 - 08:36 pm:        The basic suspension setting have just been posted on this board under the topic " suspension settings ?' They are a good place to start.   Zxmarc Posted on Tuesday, May 17, 2005 - 08:37 pm:        thanks jon   Tpoppa Posted on Tuesday, May 17, 2005 - 08:47 pm:        It sounds like the combination of your front and rear preload are set too aggressively. Increasing front preload and/or reducing rear preload will reduce the headshake effect. Has the bike been modified in any way that affect ride height? Raising the fork tubes in the triple clamp, etc?   Blake Posted on Wednesday, May 18, 2005 - 06:09 pm:        Even a bike with a steering damper can exhibit the head shake you experienced under similar conditions. When/if the front tire makes contact at an off-angle to the direction of travel, severe head shake (tank slapper) can result. It happened to Jason Disalvo in the Superstock race this past weekend. What the damper does is help more quickly damp out the violent harmonic oscillations that can ensue. The only sure fire way to prevent such unwanted oscillations is to keep the wheel straight and in-line with the direction of travel or to keep it from ever leaving the ground. Other factors can help too, like a loose relaxed grasp of the bars. A tense grip on the bars can exacerbate any potential headshake. Glad you made it through your harrowing incident.   Izzinya Posted on Wednesday, May 18, 2005 - 09:07 pm:        could also be neck bering adj... just my 2c worth but these guys are right on Izzinya   Opto Posted on Friday, May 20, 2005 - 04:56 am:        coming out of slow corner on the gas... a few bumps in the road and my handlebars almost tore my hands off, As Tpoppa said "Increasing front preload and/or reducing rear preload will reduce the headshake effect" If the rear preload and damping is set much too hard the bike will do exactly what you describe, as I found out to my surprise one day, when I didn't change from pillion to solo settings. I also got my ••• kicked off the seat but the bike straightened out pretty quick.
