The cams in my NC30 are very worn and pitted. I can't seem to find a set of decent used NC30 cams. I found some nc35 cams. Question is, are they a straight fit and how will the performance of the engine differ? Anyone here with first hand experience?

thanks in advance.

Stick them in - they are lighter and have slightly different exhaust duration..but a good fix.

any perceptible change in performance from doing that? (not that i am looking for any)

No idea...but I imagine they would make some mini differences along with many other little updates...

yes, better for sure. i have a set of RVF cams in the standard NC30 heads on my UK spec bike. that with a couple of other subtle internal mods make it pull far harder than it ever did.
