Sorry should have given a bit more info....i'm a newb to strokers since my honda mt50 when i was 16.
I've had the bike since oct last year and due to weather only done about 120 miles on it.
It runs fine and starts better now i've fitted new plugs but its been making these noises intermittantly since oct.
As a new owner you do get a bit nervous of impending catastrophy.
Guess i should stop worrying.
