Looking to put a set of CBR400RR cams into my 1989 Honda CB1 to get some extra BHP out if it

I've heard this a nice & easy, affordable swap.

I'm from Canada, so these 400cc bikes are VERY rare as is (only sold a few hundred CB-1's from what I've been told, and thats it. No 400RR or anything else) Please excuse my lack of knowledge

What year CBR400RR cam's would drop into my 89 CB1? Should I try and find a NC23 400RR to fit my NC27 (I think that is what the 89 CB1 is classified as)

Thanks kindly for the advice!

nc23 triarm. They're more likely listed by model designation than by year. nc23 aero > nc23 triarm > nc29 gullarm.

Why thank you kind sir! :)
