Bike wander

[mastermechanic]

I've been having a problem with my '99 Venture wandering or darting side to side when hitting uneven roads or bumps. Yamaha checked the suspension and said it looked ok. I still feel something is going on. Any advice on what could be checked to diagnosis what could be happening? How do you check the front forks for problems besides leaks. Is there a way to check the spring tension from side to side?

Have you checked your tire pressure and tire wear?

Mine did the same thing until I tightened up the steering head. There is a tutorial in the 2nd Gen Tech area for it.

Most likely cause is your rear tire. You didn't state brand, size or condition of your tires.

All good ideas...and maybe check and see that the fork pressures are the same for each ...no more than 7lbs. and equal.
