Puff Coming from Airbox SMS630

Little bump thread in regards to an issue im having. Havnt gotten the bike up yet and think this may be contributing. When attempting to start it up a puff noise comes directly out of the airbox. Does anyone have ANY idea what this is? I can put a video up tommorow as an example but i cant find anything on google about it.

Any top end work performed, cams worked on or removed, Valves adjusted, etc ?

Yes, removed the head cover and removed the cams, but did not go any further.

Puffing out intake is a sign cam or cams not timed properly.

It may be, the bike started up fine before the disassembly, but now does the puffing upon reassembly. When i had it open, before removing the cams i had manually set it to top dead center, i did not adjust the timing at all while it was open.

Im still fairly new to this, so please dont pull your hair out if i say something dumb

This may help.

That may be exactly it when i put the cams back in, ill be back with a response when ive had a chance to crack back into it. Thanks for sending that to me

Late response, but your solution worked, thanks loads. I'm riding again
