What else have you done to it?

What filter? Have you messed with the airbox? Is this lack of go at 5-6k rpm?

[vfr-nc30-2010]

hi yeah the air filter looks like there is a slight lil gap , air filter is standard black casing with red in middle hrc i think

also sum times i can hear poppin sounds from under the tank??????

and yes when it revs to about 3 to 4 rpm it struggles then bout 5 to 6 its ok?

also had front head changed n shims and valves done new gaskets 2!

So , What jets were in it? Is the airbox all there, including snorkel and the rubber flap above the top rad?

The std filter is a folded paper jobbie. HRC foam is see thorugh..so you don't have one of them :-)

[CMSMJ1]

Have you got the snorkel in the front of that airbox? Or is it a large hole?

nice and clean though..love it!

thanks the rubber scoop aint on the bike (scoop that cools carbs down) and on front of the air filter theres a bendy rubber slot facing down towards front plugs if u under stand that lol

Here's a flap:



Here's a snorkel:



Is that what you've got?
