Backfiring is a sign of bad valve timing. I hope it isn't that.

hey thanx for the shout out

i have the timin set to T on the number 1

not 100% sure if its exhaust stroke or compression stroke .however both ways the bike does the same thing

Has to be valve timing. Probably 180 degrees off. Good luck.

I agree, 180 out. At least that way you won't damage the valves. But you will need to get that checked asap.

I only really know 1100 and 1000's but turn to T1 check valves on #1 both should be loose..if not turn again to T1 now both should be loose..compression stroke...which way did you set your cams wheels to??? only second way works.

Check the plug wires. Each coil must have a wire going to each side. If it does reverse the plug caps on one side and try her. If that doesn't work then put the caps back on that side, reverse the other side and try her again.

Hope this helps.

Sticking or wrongly set floats.
Damaged float valves.
Sounds like you will have to rebuild the carbs.
Need to purchase the proper rebuild kits and follow the instructions precisely.
Lucky thing you were doing the comp. test when the fuel splashed out . If you had tried to actually start it ... !

naaaaaaaaaaw it wouldnt have gone kaboom, it would have hydrolocked, scary thing but easilly remedied, do the carbs again and bench test them before ya put them back in

Don't be so sure.
I heard my neighbours pickup hydrolock from a leaking head gasket. There was a loud bang and it started but with a bad knock.

As near as I can figure the cylinders weren't completely full and one fired, when the others came to the top the coolant in them couldn't compress but inertia kept the crank and pistons moving. End result was three collapsed pistons and bent rods.
