Zx12 wobble? |
hi there people,i have a zx12 on a 51 plate and i have a slight problem with a wobble {left to right} it starts when it gets to about 160 and as i go up it gets stronger so by the time it gets to 175 it feels like its going to shake the bike apart.1the bike aint been crashed.2the wheels have been balanced.3the back wheel is straight.3tyre presher is fine.4 no slime in tyres..NO DAFT ANWSERS PLEASE Is there any tight spots in the chain or damage to any brake parts? but i would think its more than likely a wheel bearing starting to go! I know the wheel has been balanced, but closely inspect the tyre for anything out of the ordinary. Check your head race bearings too, if these are starting to wear, which is quite likely on a bike of that power or are even loose at the speeds you go that can really exaggerate things Failing that get it into a good shop as no likes a shaker Good luck James Along with all the other answers - Check the wheel bearings. Get a wheel off the ground and try to wiggle it side to side. Check that the F & R axles are torqued to the proper specs. Especially the front. While the rear wheel is off the ground check the swing arm bearings (no one ever checks them). It's very importand to torque the swing arm pivot bolt. Loosen the nut and re-torque it to specs. Maybe a steering dampener would help. first check head race bearings, then fit a quality stearing damper, at those speeds you should fit one anyway. |
