Does the Rekluse allow any engine braking at all? Can you rev the engine till the clutch engages like a snowmobile?
The Rekluse is a centrifugal auto-engaging clutch. As long as the engine speed is above the pre-set stall speed, the clutch is engaged, including on deceleration, so yes, you have totally normal engine braking with one. What you will not have is the ability to bump start the engine (both EXP models will allow this if temporarily readjusted to). Also, if you are idling in gear, and push off down a hill that way, the bike will coast as if in neutral until you blip the throttle, at which point the clutch will engage, and engine braking returns.
The stall RPM, or engagement point, is adjustable, and is usually set to just above an idle. The effect on take off is very much like a car with an automatic transmission, except there is little or no tendency to creep at idle.
FYI, the auto clutch won't get rid of the pop stalls so aggressive corner to corner riding and technical up hills still require a finger on the clutch lever to avoid.
Explain what you mean by "pop stalls". When correctly set up, brake stalling is nearly non-existent. Still can happen, but not very often.
Thanks for all the input, lots of interesting takes on both.
I found a used Z Start Pro on eBay for $350, so figured I'd give it a go. I have ridden a bike with one and yes it was definitely strange at first, but that fact that you can still use the clutch if you want is a nice option although from what I've been told and read you won't/don't need to.
I will give the Rekluse a chance and see what I think, worst case I can always sell it and likely not lose much.
May give the flywheel a shot later too.
That's how I got mine. Great deal. If you don't get the manual with it, you really need it. Download one from Rekluse's web site.
