Wow..this guy roger never sleeps..he's answering me at midnite..here is more info on the cam situation as well as info for engine building from his experience.
WOW what a quick reply!
I try my best to be efficient!
Can you convert the gbp to dollars?
Aprox $2880 USD at this morning’s conversion rate.
are they available now?
shipping time to USA?
3 Days by UPS (included in the price)
Yes the heads will be ported and ceramic coated combustion chambers/valves/exhaust port...looking for mid range...wonder if these cams are a little too aggressive???
No. They will be fine they were designed for BSB Superbike short circuit racing and the World Endurance racing where power out of the corners is the key to success
where does the power band lie on these?
4200rpm to the rev limiter at 11,200
So springs, retainers, cams in the kit?
The kit contains camshafts, slotted camwheels, Special valve springs (inner & outer), spring base plates and spring top caps.
It does NOT include the 16 Honda OEM valve collets part number 14781-MBB-003 which I think you have called “retainers” See attached photos
Anyone making the flat faced HRC type valves to get a true 12.7 CR out of the hi comp pistons??
I think it would be much less expensive for you to source the HRC type valves in the US rather than Europe or possibly Australia.
After much development work alongside HRC, Mamoru Moriwaki from Moriwaki Engineering, the sadly late Bob Hayashida from BVH in Reno and myself as the three appointed HRC domestic satellite development teams on near unlimited HRC budget it was collectively proven that the best results were produced for usable power and reliability were HC Pistons of 11.1:1 or at the very most 11.6:1. Both of these are now produced by JE Pistons in the US. My own personal experience and the ones that I recommend are the 11.1:1 JE’s. I know all the fancy computer programmes will tell you that 12.6 :1 pistons produces more power but believe me when I say that in practice they are full of issues especially the Wiseco product. The majority of blown engines from around Europe which have come to my workshop for salvage or repair had either Wiseco 12.6:1 pistons fitted or quick shifters fitted to OEM gearboxes!!
With regard to quick shifters there is no problem when they are fitted to a close ratio gearbox for example a NOVA box
I APPRECIATE your help greatly!
Looking forward to doing business with you.
I am always happy to help RC51 enthusiasts where I can whether they purchase products from me or not.
In your opinion, are the carillo rods, falicon crank lightening prerry much mandatory or just nice to have? I would appreciate info on what MUST be done and whats just NICE TO HAVE....
There is no need to to use Corrilla rods as the OEM rods are perfectly adequate and can also be polished and lightened. For added response performance I always lighten and polish the rods and crank but this is mainly on full racing engines (see attached photo).
I have fitted Corrillo rods on a number of bikes at the customers special request and there has been no issues at all but there has been no added performance over OEM rods
Hope this helps in your deliberations.
