Rear Suspension effects...

so after getting to the track and realizing I had set my front suspension up wrong (and fixing it) the front end felt GREAT. (35mm rider sag) Didn't even dawn on me until I got home that I had the rear set wrong also. It was way to soft which is why I felt like my back end was sliding around all the corners. Is that correct? soft rear suspension= sliding? I'm sure it's not the tire this time cause it still looks great

I think if your rear is set too hard, it can push the rear wheel to slide as well.

not enough preload can cause the rear to pack and slide. Too soft a rebound can cause the rear to slide bying coming back to fast and not letting it absorb the load. Too much compression can also cause the rear to slide by not letting the rear shock do it's job by compressing when loaded. I suppose it all depends on what part of the corner it's sliding. Try what you did with the front and test it again.

Not enough damping will make it feel like it's sliding. Did it feel wiggly or just felt like it was sliding out?

Definitely know how to fix it, but I didn't realize that was the problem until I got home (I was blaming my tire lol) live and learn I guess. I just wanted to know if that is one of the effects of a soft rear suspension. It was alright until I started to get really leaned over and then it would slide out. :bang there's always next time

Out of curiosity does anyone know what times people were running in intermediate on the full course?

So it was sliding on entry? Throttle closed, maintenance, or rolling on?

I've been having trouble with my rear for the last few events on the bumpy tracks (Autobahn and Putnam) eating tires. Ed K. and Drucker have both helped out with it and it was much better yesterday. This whole time, I haven't been getting perceptible slides (or I my ass isn't the finely tuned data acquisition instrument it should be). The last session, though, I was spinning up in T9 on the north section (onto the north track's S/F straight). It didn't really get out of line, but I could feel/hear it hook up.

In I, I was running 3:08s or so, Troy (R6 #90) was getting 3:02s or thereabouts, Hernan (black SV with blaze orange wheels) got a coupld of 2:58s. Some of the folks I was cruising behind in the afternoon were around 3:10 or a little higher. There were probably some in the mid 2:50s or quicker, judging by the way they were coming past my slow ass! I remember you coming around once or twice, but I didn't make the connection to the with the naked kawi until just now.

Nick don't worry about laptimes right now. Just get the tracktime in and your times will drop considerably. The more track time the better. Work on doing laps in your head. What gear you are in and what lines you are taking.

Good advice. I just wish I were Zen enough to take it! I'd have been much better off yesterday afternoon focusing on a couple of corners that were bugging me rather than trying to go 'fast' and failing.

If I were worried about lap times I would have been asking people at the track what times they were running not at ho,e online and it felt like my rear was sliding on entry, not necessarily out of control but I wasn't able to throw the bike into corners anywhere near as hard as I was at BHF the end of last month. Im gonna try and sell the tires I have to fund my cruise next month but if they don't sell I'll just have to do another track day before I switch to race tires My best lap was a 3:04 but I was anywhere from there p to 3:!2
