I've been away from home for the last two weeks, so my bike has been collecting dust in the shed. I started it up today and it was a bit reluctant starting but it started. Let it warm up for a bit and it kept stalling. Thought I'd see how it went on a ride to the shops. Got to the gate and noticed a few bits of mud near the exhaust pipe when I went to open the gate, but didn't think anything of it as we have a dirt driveway. Pulled onto the road and noticed that the engine sounded like it was labouring quite hard under load. I was about to pull over to turn around when I heard a bang, the bike lurched forward, and immediately started running like normal. Rode it around for a good 10 - 15 k's and it's running absolutely fine now, and not stalling at all when idling. Does this sound like there was a blockage in the exhaust pipe to anyone else? Should I be checking for anything else? I'll be heading off shortly and wont have access to the net again for a few weeks, so don't be offended if I'm not quick to reply :-) Cheers, SL.
