Duo Discus XT

I used to ride a heavy dirt bike in the early 70s.Â* The compression
release was a Godsend when going slowly down a very steep hill in the
dirt.Â* It really kept the bike slow.Â* I sometimes wondered if turning
the ignition off would have been better or not, but, in the 70s we
didn't have electric starters on dirt bikes.

Of interest (as it seems counterintuitive), why does the decompression work to slow it down?

No idea, but it works in cold temps also. Keeping deco pulled slows down prop considerably faster. It has nothing to do with opening and closing it all the time.
