Website

got a complete, running, 2004 engine for 599 with free shipping from these guys...http://stores.ebay.com/SoCalMotoPart...4.l1581&_pgn=2

they seem to have an assortment of parts for the RC...

Now, if i can find cams, springs and a shaved durhban stator assembly I can build a nice spare engine..

QUESTION: are there aftermarket valves that are flat faced or just hrc ti ones?..want to avoid ti if possible for reliabilty issues (I've read)...

mike pond at tuned performance has a race team..says he knows some members of nicky's old race team and might can get someone to build it...torgot his name...

anybody have answers/feedback? good places to but new parts i.e. wiseco, yoyo slipper etc etc...any old durbahn stuff around?

The HRC valves were flat-faced, which is where the full 12.8:1 compressions ratio resulted when used with high-compression pistons.
The OEM dished-face valves is what lowers the compression ratio down to 11.8:1.

However, good luck finding the HRC valves. They've been unobtainium for a number of years.

Kibblewhite Performance has made a titanium valve set for a few racers in the past.
They are to be used with their valve seats which are compatible for titanium valves.
And their Ti valves are flat-faced, giving the full compression ration.

They also made the Ti spring retainers for use with HRC/Moriwaki springs and spring seats.
HRC springs are also pretty much history.
If an HRC valve spring set were obtained, it is possible they could be reverse engineered.

The Durbahn lightweight alternator was for race use only at higher revs.
It could not power normal electrical loads for street use.
The OEM altenator rotor can be removed and a few thousands (around .020") shaved off for quicker throttle response.

Pankl in Austria, owns Carrillo Rods and CP Pistons here in the US.
The Carrillo rods I already have in my engine, as well as CP pistons.
CP pistons also come with DLC coated wrist pins also.

wow guys...tks for the info!!!! hmmm, nobody kaes aftermarket, flat faced, SS or stellite or some other material besides ti?? Any idea if kibblewhite still makes their sets? I was reading guys were going to the al retainers cause someone broke a ti one....I have owned my rc less than a year and so I am playing catch up-reading and asking questions to get up to speed...this site is my go to place for info and parts....great guys here!

I appreciate the info...falicon still doing cranks? do they machine your crank or sell you a new one?

Derrel...

I was reading that the stock Honda rods are really strong..true? no need to go to carillo????
I see JE offers a 103 big bore piston...is the respray on the cylinders walls equal or superior to the Honda sleeve treatment?....

Apparently hrc used stock rods in Aaron's/Colin's motors (would pay to confirm that,I'm no engineer!) but when I purchased angry cams off Dale Warren he strongly recommended using carillo rods to reduce reciprocating mass. I'm in the planning stages of building a big motor and have spent the last 3-4 years gathering info from around the globe,there's still plenty of stuff available to do what you want if just takes a bit of time/patience finding it all.
Good luck!
