Hello, can someone explain the engagement settings of "low", "med" and "high" to me. I just installed the Rekluse a week of so ago and I think I like it but it seems to me that the clutch is slipping a little much. I have the free play set as per the manual and all the clutch components are nearly new. Today, it seemed like the clutch would slip in upshifting from 3rd to 4th down a straight. I would think I was well above the rpm that would lock it up. I think I would like it to hook up faster and not slip so much and the most important characteristic for me is the "No Stall". Thanks

Low, medium and high refer to the RPM where the clutch engages. I always set my Rekluses up to engage at "low" RPM, or for "hard" engagement. That will eliminate the slipping feel.

With either the EXP or the Core EXP, the free play at speed must be correctly set. Rekluse refers to this as "free play gain", since in the normal automatic mode, there is no play at idle. At 4000 RPM and up, the cable has to have a fairly normal amount of free travel, or it won't engage completely, same as would be the case with a standard clutch. This, and not your speed or rate settings is more than likely the cause of your clutch slippage.

The Rekluse manual explains engagement speed and rate pretty well. Engagement speed is the RPM at which the clutch begins to close up. It is controlled by adjusting the release springs in the EXP ring. The rate is how quickly the clutch locks up once it starts to engage. That is controlled by changing the weight of the wedges. The engagement rate also influences how quickly the clutch releases when braking in gear and such also. The more quickly it locks up, the less easily it will release as the RPM's drop.

My own favorite setting for my Z-Start Pro is medium speed, "slow" rate

Thank you for the explanations. I will check that free play gain also.
