Rough Running on 2010 Mk.1 961
Hi ,Can anybody help me please? I have a Mk. 1 961 that originally ran very poorly at low rpm , I had a power commander fitted ( a BMW 900 twin -same firing order as Norton) it has been running as the bike should have until last week when I got caught in a traffic jam and the bike got overheated and very unhappy. The bike will now not run cleanly at low revs or on constant throttle but will run perfectly when under load .
Thanks for any support. regards Keith
