R1 and R2 camshafts

[Paladin528]

The Cali and the 49 state cams are different PART NUMBERS. Cali is a -770 and the 49 state is a -670. The R1 and R 2 have nothing to do with it.  I cannot order and R1 cam or an R2 cam from Honda. I can only order the part number I want which may be either an R1 or R2. More than likely any cam ordered new will be an R2.

That's right!, but the # u order will either have a R1 or R2 on it.
read the other posts. chillerman ordered 49 state cams and got ones with R1 on them. He removed the cams from his calif emissions bike and it had R2 cams. go read the post and MY Post about my R2 cams, I think i was pretty clear. u are incorrect what your stating it isn't a revision. READ the OTHER Threads and this one completely.
And due to EPA emission laws, Honda can't just do a revision for an emissions related part without going thru hoops and lots of $$$$$.
 
AND do u really care or just want to complain like the others have and comment when u don't have the full story.

checked some GW GL1500 cams on ebay.  They are either pairs of R1 or R2 stamped on them. 49state and non GWs are listed with same cam part # on procaliber.  one side not even avail anymore. did Honda secretly use special R2 camshafts in non-49state bikes.
The Honda/EPA plot thickens. 

Hey CA, if you would send me one of your original R2 cams from your 98, I could certainly find if it is 49 state or california spec as per the information chart Blackduck posted. I for one am very interested in getting to the bottom of this as I, like many others, am interested in having my bike run as good as possible.  I will pay for the return shipping.

I haven't change the cams or heads yet, so they are still in the bike. waiting on new valve springs.
Found some info,  MZO is the code for Valkyrie Std/tourer, just about all parts will have that. The I/S uses MBY for parts just specific to the I/S like the shocks.

However in this case and other parts MZO is used for all camshafts.
I'm almost 100% positive the factory screwed up putting in an R1 and R2 cam. I surmise they saw MZO and the L or R and installed them not knowing there are R1 and R2 cams. If some bikes are found with a L R1 and some with a L R2, I would be 150% convinced they screwed up.
I checked the journals of these used R1 cams, both in spec and actually on the large end.  Lobe height also checked out.

  OK,, well for the time being I'm done with it.    I'm going to chase my short comings back to the carbs....   again....    it's always the carbs....    I'll get a chance to check this out definitively at some point, but less of a priority than it was when this post first started.

If that is the case then the guys riding around wit one R1 and one R2 installed must be riding the roughest running flat sixes on the planet because the cams are timed differently.
Part revisions and supercessions are done all the time even for emissions parts so long as the change does not affect the designed functionality. For example a material change or even a supplier change.
I have read all of the other threads and from what I am reading it is all speculation as to the markings because everyone who checks gets a different result.
I deal with parts on a regular basis as a part of my job I know how the system works. Imhave also been a mechanic for almost 30 years. 
I do care as the Valk is relatively new to me but I guarantee that mother Honda did not screw up and put one Cali and one 49 state cam in the same engine.
I am done with this conversation.

Trying to interpret foundry markings as something related to the final enhanced product is a game, nothing more, absent any verified substantiation from the source, of the parts. You are permitted to have your opinion, but that is all it is. A best guess!

Another ebay seller of cams. One marked R1 and another marked R2.

Like I stated before if it ain't broke don't fix it. Just leave well enough alone and ride the damn thing or sell it to me with whatever cams are in it

if your not interested then why post and degrade others? but for your info using 49 state cams can provide 2-3 mpg more and ~ 10hp more.

Not degrading anyone but why are you worried about something that isn't a problem?  And 2-3 mpg's would not be noticed 15 miles MAX on a tank. Hell let off the throttle a bit and it will increase waaay more. And 10 more hp, do you really need it? NO.
My whole point is why worry aboutt something you can't do anything about? (And if you can it will take years to recover money spent doing so)Ride your bike don't feel the need to tinker or tweek it for no reason.
Now if you were talking 10+ mpg (50 miles per tank) it may be worth looking into.
I just feel some need to find something wrong with something that isn't.

EPA is what is "something wrong" and makes ALL vehicles get reduced MPG. get rid of the EPA stuff and MPG/HP/Ftlbs go up.
when new would always avg 32-34 mpg per tank, now with all of my mods I avg 39-42 per tank running 70-80mph, straight hwy I will see 50mpg and this is at 116-120 HP.
and with the new ported heads and R1 cams will see even more.
