hi all, hope you are all well and complements of the season
though id let you know how i was getting on with the 150, it blew up
seemed to suffer coil bind and dropped the exhaust valve, anyways got a new 1 under warrenty.
im now having , i think is jetting issues so i am hoping for some advice.
the bike starts fine, idles fine, and even blips fine, however when you wind the throttle on without load past 1/4 turn it makes a wrrr wrrr wrrr sound and seems to be when it hits the second circut and wont rev.
i have a mukuni 24mm push fit carb,engine has been ported and it has a z40 cam and springs, the outer rotor is set to just past middle (advance), valves are set to 0.005, jets ive tried are 114,110,107.5,100,80, also tried needle settings from top to bottom, the 80 seems to allow it to rev further before it wrr wrr wrr's. im at a complete loss
failing your help im going to have to buy the carb that comes with the engine
eagerly awaiting replys
