Handling

[hard2kyll]

I recently have been having issus with the handling of my 2011 GSXR/750. It all started (in a galaxy far far away), not really, but after the local paving company put down the slurry/tar covering on the pavement in my neighborhood. I would take my bike out and the suspension (unadjusted stock) would handle great, I could lean it perfectly. Since the tarring in the street the feeling now is the front end wants to slip when dipping into corners. Another sensation is the bike "seeking" for grip. Its almost like it skates from right to left.

 

I have replaced the stock BT-016 tires that come on the Suzuki bikes with Michelin Power 2CT. Air pressures are checked and checked rigorously.

 

Looking for some suggestions; possibly a steering dmapner issue?

Thats a tough one since so much has changed in your example. The first thing to ask what are your tire pressures? A steering damper is there to help isolate and nullify the riders inputs ( death grip on the bars), they don't do much else. A loose steering head or a tight steering head can cause "feel" issues.

It may all come down to tire pressure and the new tires vs the old.

Tire pressures are even front/rear are 36. Old tires or new have the same feeling.

 

I took the bike to a shop here in Vegas and had a guy ride it and he mentioned the head bolt or possibly bearings. He asked if I had unplugged the electronic damper to see how it felt but have been a little yellow to try that.

my guesstimate is that the friction coeffecient for the road has nose dived after the tarring.

Does it feel the same in left adn right corners? Try taking your hands off the bars after closing the throttle, see if it wanders consistently one way. If so then the rear wheel is out of line, which could be after taking it out for a new tyre and replacing it. This will make it feel bad when turning in on one side.
