I have the J&S unit in my Syclone working & functioning as advertised.

Does not matter if you have a pancake 4 , inline 4, 6, 8 , v6, v8, etc, it will work on all those engines & more.

I also have a new J&S for my inline turbo engine, whenever that will happen.

Here are some videos for you to watch.
