Vir question
« on: September 03, 2020, 06:12:18 AM »

Hey guys just wondering if anyone else has issues going through the fast left after going under the bridge.  I think that's turn 9.  My front end what's to chatter and vibrate to the point I'm afraid I'm going to.lose the front of the bike.  Are there alot of small bumps there or what?

Yes I think it’s a little bumpy going in there. But not so bad that I can’t push through that corner.

What bike are you on and what group are you running? When was the last time you had the oil in your forks changed? Have you had anyone help setup your suspension?

I am riding an 02.ZX6R. In advanced group.  I'm not fast usually doing around 1:37 lap times.  I change the fork oil every season in it.  I had it set up at the track a few years ago. But it was just rebound and preload settings.  I have never actually had anyone tear the suspension down and set it up that way.

37s on an old ZX-6 ain’t all that slow... LOL

Different valving in the forks could probably help the bike handle bumps better, but I would defer to a suspension specialist.

For me, the bumps are worse when my tire pressure is off. And I noticed Monday that the track temp wasn’t typical for August and my tires weren’t keeping the same heat as I expected. I had to play with my front pressure a little to get it to feel right.

That is turn 10 or ECU-a corner and it only gets bumpy when you take a line that does not hug the curbing on riders left.

So if you take a straighter line to the apex of OG ECU the bumps are less?

I also find a tight line there is farily smooth. I'm running 1:40.xxs. Slower than you.

There are lots of things that will cause chatter in 9. You can try these, but do them indepedently! You run dunlops, so run the front up to 36 hot off the warmers. Raise the front of the bike to unload it a bit (try 5mm) and give you more trail stability. Before everything else make sure your head bearings are good and torqued well. get the weight off the front of the bikme and grab the forks. pull them back and forth to make sure there's no clunking. Like others have said, the fork oil level needs to be right. You can also add a few clicks of rebound to slow it down.  Message me on messanger  if you want to chat about it
