Hi out there...

maybe it can be important to someone..maybe not.

I tested for about 10liters of fuel a new BOSS. And I can say that it is an amazing engine.

Very regular on the carb and a lot of power. Top Speed like a Gimar JP but from the bottom a lidlebit more.

The engine comes with ceramic bearing from switzerland. After this quantity of blasted fuel , the engine still got a lot of compression. It didnīt stuck anymore but you need a lidlebit of power in your fingers tu turn the flywheel.
Not Bad. I changed the conrod at 7 liters...( normaly after 4 ..but I was to lazy ).

Because of my very good fuel the crankpin is like new.

It ainīt to be a 9port . This 7port engine is quick and durable.

Try it you will be impressed for sure.
