hi guys
not started my bike for a few weeks kept dry under heavy duty cover
wouldnt start on side stand but if i upright bike starts fine idles fine
when warmed up ok
is this carb related cheers
i own nc21

i couldnt give any advice nc21 specific, but sounds like it could be carbs if that happened to my bike.
is it low on fuel or got bad fuel? a few weeks i wouldnt think is enough to make the fuel go bad but is the problem still there now you have run the bike and warmed it up?

problems there till ive been for a run then she"s fine
idles on stand ok just like it from cold
