Guys,
The last couple of days I've had a single back-fire...hardly even that...just a 'pop' but loud enough, when I start her up. Anything to be concerned about ? I never re-jetted after removing the snorkel figuring all was OK since it was jetted when the pipes were fitted. It runs great apart from that. Thanks for your help.
