Husaberg FE450 2009 cracks but wont satart.

Hello reading this forum for a while but this is my first post as i have found all the answers i needed without asking up until now but now I'm stuck.

I have a Husaberg FE450 from 2009 with 101 hr on the clock that cranks but wont start. Last time i used it it started almost perfect and had no where behavior.

So what do i know at this point.

I have changed the fuel injector and The plug is wet so there is fuel coming to the cylinder.
I found that the pulse generator was bad but is changed now, have new plug and it is correctly gapped.
I just made a valve adjustment so they are in spec.
I have recharged the battery so it stays above 10.5 volt when cranking.
I have adjusted the TPS so that it has at 0.64 volts when idling.

The engine cranks fine and i have no error codes. it some time gives a poping sound from the exhaust.

I don't really know what to check try next any suggestions would be welcomed.

Best Regard.

Found the problem.

Was a valve that did not close as it should. Really weird.

after all this i should maybe write a error searching guide from the perspective of one new to engines. i think i would be good for all us new ones here.

anyway thanks for the help.
