Hey guys.. need some HELP. Bike is killing me

Did full rebuild (crank up) crank went out

Bike will fire for a brief second off kick starter and die. Don’t like it but if you bump start it, it will start. (Had it started off the kick start today after a bunch of kicking)

Double/ triple checked timing (everything lines up on both sides) new chain
Sent cam out to make sure it didn’t spin (was within 1/4 degree of spec. All balls cam

Exhaust valves 12 thou— intake 5thou

Leak down test is great.

I just did a comp test and found 140 psi which I find really high? Compression arm seems to me moving just fine on the cam?

Check the plug after kicking and it’s wet

Thanks for any help on this one

Put in new fuel pump/filter and cleans the injector. Still the same

Make sure decompression mechanism on cam is working properly
it might be hanging up on using kick starter cause its not turning fast enough
as when you bump start it

It looks like it is functioning properly, The spring pulls the arm back with ease. Not sure how else to test it
