squeaking noise while shifting

I am getting a squeaking noise when I pull the clutch in while I shift.
I believe it is coming from the front fork. pretty sure it is. what does this sound like? Thanks

Does the squeaking also occur whenever you rev past 6500 rpm or so? I'd check that. If so it just a slightly rusty/dirty intake flap. Mine squeaks when I rev up past 6,500 and everytime I clutch in and shift the rpms dip below 6,500 and it squeaks again.

Could it be the power valve?

It's the air intake flapper, opens up around 6000rpm.
Keeps intake noise level down at lower RPM's
Manufacturer will say it improves power etc etc, unlikely

It doesn't. Otherwise, it would still be in operation when the off-road maps are loaded up. The TOR map has it open at 900 rpm (essentially at idle), and I'm not sure what the Arrow map does. Most people I know who are trying to get an extra horsepower or two out of a 675 motor just remove the whole vacuum system and call it a day.

It's a squid thing. You wouldn't understand.

Go soothingly on the grease mud, as there lurks the skid demon.
