   Notice how it sounds like a Veyron at the end? I’m not a bike guy, but I can certainly appreciate what people come up with these days.

   Is there any issues with liquid lock, like on actual aircraft radials,liquid lock can pop a cylinder of just by moving the props by hand..

   JRL installed a oil return line and a one-way valve in the bottom cylinders that automatically pumps the oil back to the tank minimizing cylinder lock. -Ollie

   wonderfull,I have spun many props on radial engine and one has to be carefull to do it right, besides we used to say that if a radial engine doesn’t leak oil, that means that there is no oil in it, hence the little coffee can under the cowlings to recover drippings.., Thanks for the reply !

   Abl178 take a look at the first production bike on the JRL site. It’s located on the bottom of the home page. -Ollie

    It looks like a Rotec. If anyone knows for certain the type please respond.

    You are correct, it is Rotec’s 171ci/2800cc 7 cylinder radial engine. JRL also offers this motorcycle with an optional Rotec 9 cylinder. Afghanpilot (Ollie)

    Thanks for posting. Actually the pipes are ceramic coated inside and out so the heat issue is not a big deal at all. -Ollie (Afghanpilot)

    I probably wouldn’t have put armor all on the tires…

    No Armorall on them, they were just new.

    Simply beautiful.

    Does it feel any different from a “normal” bike to ride?
