hi i am new to this site and i need some advice i have a Honda firestorm vtr 1000f which was working perfect i came to it this morning let the bike tick over to warm up and went out, during the day out when i stopped at junctions and lights the bike would cut out and then it would start up straight away. also while riding now and again a slight pop noise would come from under tank. i parked up at a friends house and came back to the bike about 2 hours later started it up rode a few meters down the road and bike stuttered and cut out and will now not start. the bike has been serviced about 500 miles ago.
