| Massive backfire!
What caused this?
Pulled onto a Petrol Station recently & the bike started to chug before cutting out (still a bit of petrol left). I tried to restart it, but it just turned over & over until BANG!! an almighty backfire that echoed all around the forecourt. The kind that makes birds fly out of the trees!
Run OK after that & it's never done it before or since. Any ideas?
BTW, my mates 916 did exactly the same thing on the Isle Of Man this year |
