Rear cylinder not firing after front cylinder rebuild
 

Right, ive stripped down and rebuilt the fromt cylinder, now when all back together the back cylinder is not firing, i checked sparks, they where fine, checked timin of cams that frot and back in sync and all fine, im sure everything is conmected as ive checked the bike over like 5 times, any suggestions what could be stopping it?

It seems to have fuel as after 30 second of running you get a big pop in the exhaust that im guessing is the fuel igniting

Are the cam timings correct between the the 2 cylinders? If both of them line up with the manual at the same time they won't be right. The manual says line one set up, rotate 360 degrees, then do the other cylinder.
