Just spoke to him and he said he checked it with our local Honda dealer, the guy that works there in parts is a dip shit to be honest.
Did you get them numbers from the parts book?

No CMSNL

I forgot about that site.

Reason why he was looking into this is he knows a guy that had some higher compression pistons made back end of last year for the 30 and 35 motors but he wanted £800 for a full set
He said on a fairly standard motor with very minor head work and exhaust they where getting 72hp but for £800 I would say thats a bit expensive.

Turns out the sets he had made are all now sold but he's having some more done this year and they with be half the cost so will keep posted if I hear anything and try get some more info as and when I can.

You sure they wasnt oversized pistons?

Not really sure on the details to much apart from they was made to higher the compression. When I get chance I will try get some more details on them and maybe a dyno and spec print out.

rvf pistons raise the compression on nc29 engines, perhaps that's what caused the confusion?

Thats probably where i have got confused.

Well my oil cooler arrived today (many thanks CRM).
Managed to fit it after work and fire her up. She runs really well and im happy as a pig in poo.

James what jetting have you started off with??

My final settings were 132fr 134 r mains, 35 pilots, nc24 needles, nc24 slides, hrc imulsion tubes, p/s 1.5 turns out and air tube restricted to 2mm when it was last dyno'd on the old engine
But this may have to change now im running Ricks bellmouths as ive scrapped the air tube resrictor i had to use on the cut down standard bellmouths.

Why NC24 needles and not Ricks HRC rep needles?

All i can put it down to is that my engine was so tired that it could not burn the extra fuel as it always seems to run smaller jetting compared to everyone elses bike with the sames state of tune.
Everything might change now it actually has an engine with compression
