1984 aspencade starts w/choke and revs up, runs smooth. Take off choke, engine cuts right out. The bike was stored two winters and has fresh gas. checked fuel flow and put out 50 cc in 5 seconds as it should. When bike warms up, can rev it up with choke partially on but is doggy. Can take choke off with higher revs but cuts out when I leave throttle return to idle position. Can you help??
My 'wing won't run unless it has been warmed up some. I would suggest that you r&r your carbs to make sure the jets in the bottom are working correctly. They tend to get plugged up, especially after sitting & the aluminum flaking off inside... Rick

carbs could be suffering from gummed up components. run some Berrymans B12 fuel additive in the tank at double dose, run til hot then leave to stand overnight and pray hard. hopefully all will be well, or use a carb cleaner sprayed direct in the carb, also let this sit overnight
