guys thanks for the remarks, and sure i can make things smoother, but i have found from years of expierence that smoother prior to entering the cylinder does not help! At the exhaughst port its mirror finish and thats not even that critical. The reason the bore does not match the exhaughst flange is the design of Fabrizi, and Mr. Fabrizi said himself to me, "Not to touch or match" NO NO NO!!! he said, hahaha, so what ever??? None the less the bike has not moved since its original post and build.
Today i am completing engine number 2 using the 50cc case clearenced out ot the 47.6 crank,,opposed to th eold motor being a 100cc block and too great a clearence for the 47.6 mm crank ( lower case preasure). Tonight i will install the higher case preasure set up with the same porting and same cylinder and see what happens
Much talk on here that Fabirizi is poor quality, but its all in the tuner, the quality is fine. They use the same pistons and Polini and Malossi. I have been running Polini and Fabrizi parts for over 14 years with no problems.
I will see how the set up goes over the next few weeks. Also put some new pics up of the new cases. I am also going from the current 21mm black Delorto to a 28mm Dellorto.
