The sirio engine will probably last longer and require less maintenance along the way. Its powerband is smoother. It will be more difficult to find parts, plugs, pipes etc as you need them along the way. If you flame out while the engine is hot, this engine may be a bit harder to restart and it usually marginal on fuel mileage all other things being equal

The Picco/JL will probably not last quite as long. The carbs on these have always been a pain in the rear to get closed all the way and the composite bottom can come loose easier. If you get this engine, shave .5mm off the center portion of the pinch bolt to make sure the carb stays tight. This engien make massive bottom end power and still makes good power thru the range although may be very slightly less on the top end. Makes very good mileage. As this engine is a bit older the rods (which are the most fragile part of this engine) may be a bit harder to find but not certain. There are a few outlets for Picco parts in the USA. The pipes are expensive, but easy to find in the USA.

Both engines make good power and capable of being competitive.

i bought that Ofna Picco JLR51128 brand new for $170.00 from a ebay member. Im still breaking it in currently but i wouldnt pay the $280 they are asking for it because of the issues i have heard from various members.
