Hi guys - finally got internet - just in time to post my bike problem. Last couple of days is behaving like it is running out of fuel (it's not - I checked!). Eventually cuts out, I turn it onto prime and life is sweet again - any ideas? Have replaced spark plugs, checked air filter (bone dry) and WD40'd coils. Planning to remove tank this afternoon and check diaphragm - would appreciate any help to avoid this arduous task - it's raining and I'm quite happy playing on my new internet toy!! Help!
