[QUOTE="Ducdude, post: 34946, member: 2077"] Hi all I would like your input on how to proceed regarding the above bike's set up. 1952 Shadow freshly rebuilt motor and trans from the crank up 8:1 low expansion pistons 105 cams NEW style 32mm MK1 Amals #3 side 106 needle jet 250 main jet 17thou air jet behind the air screw Burgess muffler (silencer) Stock gearing BTH No air filters 160 miles since rebuild Fresh plugs, filter, oils, valve adjust, head torque to 30ft/lbs at 100miles Nice steady idle The issues are as follows: Pick up feels good in 1st gear but seems flat accelerating though 2nd. On the motor way she runs strongly up to 85mph or so, at 75% throttle. It is an effort to get her up to 95mph at WFO and once there that is all she seems to want to do no matter if the mains at 210 or 250....She does a bit better getting to 95 with the 250s but not much. Plugs are dry and slightly sooty around the electrode but the electrodes them selves are reasonably clean... Finally the bike just does not feel lively my seat o meter says that there is only 30-35 hp at the rear wheel but all this lot is subjective. All comments and suggestions are welcomed and encouraged.. Thanks much! Cheers, Eric [/QUOTE]
