Hi all! I picked up my 2007 gixxer 600 on Sunday of last week and ever since then the front end isn't totally stable. Pretty much the bike gets stuck and slides every time I ride over a pot hole or crack. Also when I go up on curbs ( that tiny lip ) the front just almost looses all control. Does anyone know what I mean? I feel like I'm not describing it well
The tires are good so I know that's not the issue
It's as if the front acts on its own
Anyone ever experienced what I'm talking about? Pretty much anything makes the front un stable
Find someone in your area who is a suspension guru and have them set your sag/damping. Sounds to me like someone messed with the dials on the forks and had no idea what they were doing.
After checking tyre pressures readjust suspension settings back to factory stock and then go for a ride on your designated test route to compare. Doing this first step won't cost you a cent and provides an initial baseline before throwing money at a specialist tuner.
In any case the previous owner(s) may have set the bike up for their own weight and riding style by changing the settings and possibly the internals.
1. Check tire pressures first like everyone else has said. Run 38-42psi f&r for commuting, 34-36psi f&r for spirited street riding, and as low as 30psi for track.
2. Set your sag. You want 35mm up front and 30mm out back for street riding, and 30mm up front and 25mm out back for track.
3. Set your rebound damping. You want to bike to spring back up as fast as possible without overshooting or bouncing, and make sure the front and rear spring back up evenly.
4. Set your compression damping in the middle of the adjustment range, and go for a ride. Make adjustments one click or 1/4 turn at a time until the bike is compliant over bumps, but not soft like a Cadillac or hard like a go-kart.
5. Check your steering damper for any air bubbles, which will be indicated by dead spots when you turn the bars.
Thank you for all your help gentleman!!!! I took the bike to a mechanic and he cocky des that the previous owner shortened the forks and they're now set to stock
So, just the front? Do you mean pushed the forks up through the triple tree, effectively lowering the front or pushing forks down in the triple tree, raising the front? Sorry, not familiar with "shortened the forks". Shouldn't need a mechanic to tell you that as either scenario is obvious. Whether the front was raised or lowered, usually the rear gets the same treatment, so if front is raised/lowered an inch, the rear gets raised/lowered an inch as well.
Mine felt the same way when I bought it. The previous owner had lowered the front and rear and there was about 8 psi in the tires. Anthony pretty much summed it all up. Keep us posted.
