Question for y’all Newport experts... I Have several maxis which when I got them only did 18-25 mph top speed but after putting a 14 carb and intake, new air box and derestricting stock pipe they top of the stock speedo at 30mph, CAN I DO THIS TO A NEWPORT??? I SEE NO PLACE TO DERESTRICT!?!? Also I heard the engines are more finicky on Newport’s but mine is just a non injection e50 (1978 Puch)
