Speed Engine & 46 Polini - montaggio e prova su strada.

Let's see how this block performs! Hi everyone, in this video we'll look at Cracrà's engine, assembly, and road testing. We've already seen the components in previous videos, so I won't dwell on the descriptions. The exhaust on the cylinder was ported to 57% of the bore instead of the original 50% (23mm), and the rest was finely re-ported. I later managed to test the engine, first with the original 94mm pulley and then with a 70mm pulley... I won't spoil anything; the video will show everything, including the speed and engine rpm readings... If you have any questions, I'll answer them in the comments. Be sure to LIKE and SUBSCRIBE with the BELL so you don't miss the videos I upload!!! I'll be doing a LIVE show for friends soon. We need to clarify a few things; we'll talk about the work to be done and other interesting things! In the meantime, I'll leave you a list of videos and my private contact information. I'll reply to everyone, but give me some time!!! I'll talk to you during the video's PREMIERE; I'll be online! See you next time... BYE!
