Yes it sucks, I had this happen to me on my Norton 32 years ago, it back fired throught the carbies when kicking it over, leaking fuel tap, before I knew what was happening I had a fuel fire and the fames were running up my left arm, lucky I had my leather jacket on, I dropped the bike in a big panic, but I knew putting water on it would have been worse for it, because the 850 is in a Featherbed frame and my fuel tank wasn't bolted on I was able to pull the fuel tank off the bike once the fuel hoses melted and a friend that was standing beside the bike when it happened race away and grabbed a old tarp the was in his shed and laided it over the bike to suffercate it.
After I got the bike home and looked at the damage, I was surprised it only damaged the wiring, burned the paint off the fuel tank, melted the speedo glass and destroyed the seat, the next day I had the bike rewired, I left the burnt paint on the tank, it looked sort of cool with the charcoal paint job :lol: had it fired up next day but had to waIt for a week for the seat to get redone,
I rode the Norton like this for about 3 years and could enter it into bike shows and win rat bike comp. every time :roll: , the motor wasn't damaged but the Boya black box shit it self a week later from the fire.
What did I learn from this experance, don't run verloitie stacks on your amals when you have a leaking fuel tap.
So hope your bike is still ok, it mite look bad but easly repairable, I had to get mine goig as soon as posiable as it was my only transport at the time.
Good luck with it and hope its works out
