So last night I rode my Motron after finally getting it to really run right (it needed different transmission fluid). The only performance upgrade I have on it is a Dellorto 15.15 and a 56 jet vs the 52 stock in the 14.12. Still have the stock exhaust, I'm waiting on the performance one in the attachment (coming from Italy). But man, this thing rips! At least compared to my Tomos Bullet with a Biturbo. The top speed is actually about the same but the acceleration on the Minarelli is so much more intense. I was riding with my friend, him on my Tomos and me on the Motron. And from about 0 to 5 mph the acceleration was the same, and then boom I would rocket past him, even if I only gave it about 2/3 throttle. Now I can't wait to get that exhaust, do a little porting, and go ripping around even more.
