Hello people,
Hope you can help, have a 1992 import nc30 that had sat for 10 years spent 3 months working on it . Finally got it started motd the other day broke down on way home, the symptoms are will just about start when hot, then revs ok for a few minutes then starts to miss any throttle she just dies, when cold can start her ok will tick over in neutral for 15 mins ok.
Then I tried to ride it starts to miss and dies.
Tried lots of checks plugs ok new reg/rec tested coils wires look ok.any help would be much appreciated.

Welcome to the forum

There are people on here who know far more than me but you haven't mentioned the carbs. I assume that if the bike has sat for 10 years then you've obviously stripped, cleaned and rebuilt them with new parts?

Sounds fuelling rather than electrical?

You might have to get brave and get the carbs off for a clean and check it's not been fiddled with too much

Does the vacuum hose "suck" properly to open the fuel tap? No splits in it?
