Negative LR Bite?

That just doesn’t seem like enough to ratchet it down like that. Is the track a circular bullring where you are always turned left and hard over on the RF ? I could see with 775+ zero point and 1600@3” and climbing from there.

Matt, did you have a washer under bump or using a bump cup?

If not that explains why it was didn't bottom for 3 laps or so.

Bump was in a cup with a washer between the bump and the packers (packers on top obviously).

OK, it's common for people to not use one and the bump will push over the nut and increase gap 1/4" or more. it usually takes a few laps for it to push over it and gain gap, so I figured that might have happened and thus increased you travel where it bottomed out after a few laps.

The bottom of our shocks' spring cups actually cover up the jam nut but I figured it would be best to use a cup to prevent the bump from getting pinched down into the slot in the spring cup. Same thing with the washer on top...I figured the point was to avoid rubber pinching up into the slot in your packers. Frankly, I'm already looking forward to trying something far less progressive like a bump spring or going back to stack. It seems like it will be far easier to tune for less than perfect track conditions.

we have not tried the bump spring yet , if the track is super smooth , which ours usually is not , i still like the reg bump , but most of the time , because of a lot of whats happening to you , we stay on the two stage . My question is , will the bump spring ratchet down on a rougher track like the rubber one?

I could be wrong but I don't think the bump spring would ratchet down like a bump rubber. A spring has more of an elastic recoil. The rubber tends to stay a little crunched even after you take all the weight of it. Stores the energy longer...if that makes sense.
I've witnessed this on the smasher when bringing back up from full load. After the packers stop touching the body of the shock and it goes about 1/4 gap, stop the smasher and you can watch the packers close the gap as the bump expands. I can't imagine there is a steel spring in the world that would behave this way.
