I was out playing in the canyons the other day... As usual...

I came into a turn, got my braking done and leaned in. I leaned over pretty far. I didn't have the brakes or throtte applied, jut kinda coasting towards the middle of the turn. The pavement is in good shape, smooth, sharp etc... Front tire still has a nice profile (not too many freeway miles, not cupped etc...). As I was going through the 1st third of the turn after I got done adding lean angle the front felt like it was losing grip, then gaining it, then losing it again. Did it four or five times and as soon as I got back on the throttle it completely went away. I'm certain that I could have been on the throttle the whole time and that would have prevented the issue.

The bars didn't really oscilate at all. It just kinda acted like it was going to let go, then regained traction, then acted like it as going to let go again...

I'm just curious what it might be...

I'm thinking maybe damping settings or fork oil level.

I just rebuilt the forks and I know I put the same amount of oil in them (by measurement) but I wasn't able to do the step where you measure the oil level after the initial oil add... I didn't have any way to, but I'm sure that I got VERY close to the same amount in each.

I'm wondering if the initial oil amount is too much and they're expecting you to remove some once the damping rod gets saturated? Maybe it's not enough? It didn't feel like it was bottoming, but maybe it felt more like hydraulic lock setting in...

Just curious if any of the racers have felt this (but I'm assuming they'll tell me "get on the gas sooner") and know what might cause it.

It really kinda felt like I was going over strips of pavement that had different levels of grip, but I've been around that turn at least a 1000 times and that's never happened.

Try increasing rebound damping and see what happens.

From my experience on the XB12R, the front end felt much better when I reduced the rebound damping by 1/2 turn. I run less damping on the front (rebound & compression)than suggested by the manual. I feel this way to have more feedback and that the front gives more grip under big angles of lean.
