She is always driven , this happened about a week ago
- Drained float bowls , just petrol
- Removed airbox
- checked fuel filter , all clear
- Checked peacock valve all good, we have fuel when open , none when closed
- Peacock valve to Fuel pump all good, we have fuel
- Fuel pump to Carb , all good , nice flow of fuel with everything off
- Checked vacuum pipe from fuel pump to exhaust , no cracks , cleaned with brake cleaner
- Checked nipple on Exhaust for the vacuum pipe, no blockages , leaks , removed and cleaned with brake cleaner
- Check breather hose (below the carb fuel line) to breather , no cracks ,leaks , cleaned with brake cleaner
- Breather hoses on side of the carbs need replacing but wont stop her from starting
- Removed Spark plugs and cranked her over a few times to remove any crap , excess fuel
- Checked spark plugs removed and cleaned , we have spark (They are only a few months old)
I tried to start her without the airbox , she just cranks ; twice she started for literally 2-3 seconds
I am a bit perplexed , air, spark and fuel should mean happy bike
