California cams

[diskmark]

Hi
I recently read:

Honda only made two cams a smog ( Calif) cam for 50 states and the regular cam for the rest of the  country.

I have two Valkyries, a California (1997) and a Texas bike (2001).
The Texas bike is noticeably faster than the Cali bike.
If I locate some non-Cali cams, do I need to replace the pushrods also?

OHC engines don’t have pushrods. Just replace the cams.

My '99 CA-model Tourer wears an I/S tank, trunk, radiator pods and ICM, a Memphis Batwing and a number of usability/safety features such as communications equipment and lights. It isn't as light as a stock Tourer by any means and still has all the OEM smog plumbing, cams and whatnot.

Carb-wise, it has a set of Cobra jet needles and I/S carb springs. Airbox and exhaust are stock.

Compared to the '01 I/S (whose trunk is now on it) the Tourer is comparably fast, even two-up. If I ride the thing at sane (<80MPH) speeds I can get a consistent 40MPG; better still at 55-65MPH. I'm not really excited to swap cams for the 49-state version with that kind of performance.

Thank you for your replies.

Bagger John, I am trying to figure why the 2001 has so much more power.
Have you figured out why the 99 is stronger than the 01?

This gas mileage is ridiculous! My 2003 that now is full tourer with an I/S tank and bunch of other add-ons (and ton of extra chrome) can barely get 32 mpg. The highest I’ve seen on one tank was 35.

There are way too many variables to try and account for your poor mpg (32).

I get 40-42 when my wife is on the back of my 99 IS.

I'm lucky to get ~35 mpg when I ride alone - blaming my right wrist - and sometimes get LESS  


Didn't buy a Valkyrie to get good gas mileage....I go through a lot of brake pads too!

You swapped the standard ICM for one from an I/S, right? That's the biggest improvement one can easily make. The CA cams don't appear to be that much down in power compared to the other 49-state Valks I've owned, and the bike certainly gets good mileage.

An apples-to-apples comparison was my 2000 Tourer - the only differences between it and the '99 (apart from being a 49-stater) was no trunk and no pods. All else was the same. It got anywhere between 38 to 42MPG at the highway speeds I usually ride, and the record was 50MPG during a 45-55MPH secondary-roads ride through NE Ohio. I couldn't believe that one when we filled up after a 120mi jaunt - thought for sure the tank was almost at Reserve. Surprise...

What am I missing? Ignition coils are listed as identical part numbers across all years and models of Valkyries from 97 to 2003. I’ve seen this discussion before but this time decided to check at Partzilla amd part number is identical: 30510-KT7-023

Nevermind. Ignition control modules are in fact different. Wonder what exactly is the difference though

Different ignition advance program

the I/S ICM has more and quicker advance up to 4k rpms, after that to redline both ICMs have the same advance curves.

"Carb-wise, it has a set of Cobra jet needles and I/S carb springs. Airbox and exhaust are stock."

cobra needles are richer than OEM. without air box and exhaust mods why would u use them?
where u trying to get rid of the EPA lean spot in the 2-3k rpm range?  did it work?

The I/S springs provide for a leaner condition during cruise and acceleration.
Air velocity thru the carb throat is what draws fuel up from the needle well. the softer I/S spring allows the slide to rise faster which reduces the velocity, hence less fuel is drawn up even though the needle is higher out of the well.
