Hi California Rune riders,

I need some help from you. Even after talking to the Rune Honda support line and posting question on the Californian CARB web, I cant find out if Rune sold since Jan 1st 2005 need to comply with the CARB 2008 rule. Honda news wire does claim the VTX 1300/1800 are complying...not a word regarding the Rune.
Honnestly, I am not able to understand what's this would really mean if you walk into a Honda dealer shop in California and ask for a brand new one and then try to get it registered !
In addition if any one could find the technical data related to the CARB2008 required emission number it would be great. I would be then able to find out if California as stronger emission control than the ECC one call EURO4.

Many THX for your assitance.




Attach are the info from Honda related to the VTX

Honda VTX 1800

One of the most remarkable attributes of the VTX engine is its ability to make serious power while staying true to Honda's environmental commitment: California VTX1800s exceed the CARB-California Air Resources Board-2008 emissions standards. To keep the VTX engine running strong and efficiently, an ECU (electronic control unit) manages a closed-loop emission control system utilizing air injection and a three-way exhaust catalyzer to deliver the optimum air/fuel mixture under all operating conditions.


VTX 1300
California model utilizes an exhaust catalyzer to reduce emissions of hydrocarbons (HC), carbon monoxide (CO) and oxides of nitrogen (NOx) to meet the 2004 California Air Resources Board (CARB) emissions standards.

This is the same info I sent John I copied this from the service manual for the Rune regarding its emissions.

EMISSION CONTROL SYSTEMS
The U.S. Environmental Protection Agency, Transport Canada and California Air Resources Board (CARB) require
manufacturers to certify that their motorcycles comply with applicable exhaust emissions standards during their useful
life, when operated and maintained according to the instructions provided, and that motorcycles built after January 1, 1983
comply with applicable noise emission standards for one year or 6,000 km (3,730 miles) after the time of sale to the
ultimate purchaser, when operated and maintained according to the instructions provided. Compliance with the terms of
the Distributor's Limited Warranty for Honda Motorcycle Emission Control Systems is necessary in order to keep the
emissions system warranty in effect.
SOURCE OF EMISSIONS
The combustion process produces carbon monoxide, hydrocarbons and oxides of nitrogen. Control of hydrocarbons and
oxides of nitrogen is very important because, under certain conditions, they react to form photochemical smog when
subjected to sunlight. Carbon monoxide does not react in the same way, but is toxic.
Honda Motor Co., Ltd., utilizes PGM-FI, two three-way catalytic converters (one in each exhaust pipe) and two heated
oxygen sensors (one in each exhaust pipe) to reduce carbon monoxide, hydrocarbons, and oxides of nitrogen.
CRANKCASE EMISSION CONTROL SYSTEM
The engine is equipped with a closed crankcase system to prevent discharging crankcase emissions into the atmosphere.
Blow-by gas is returned to the combustion chamber through the air cleaner and throttle body.

GENERAL INFORMATION
1-46
EXHAUST EMISSION CONTROL SYSTEM (PULSE SECONDARY AIR INJECTION SYSTEM)
The exhaust emission system is composed of a lean fuel injection setting, and no adjustments should be made except idle
speed adjustment with the throttle stop screw. The exhaust emission control system is separate from the crankcase
emission control system.
The exhaust emission control system consists of a secondary air supply system which introduces filtered air into the
exhaust gases in the exhaust port. Fresh air is drawn into the exhaust port by the function of the Pulse Secondary Air
Injection (PAIR) control valve. This charge of fresh air promotes burning of the unburned exhaust gases and changes a
considerable amount of hydrocarbons and carbon monoxide into relatively harmless carbon dioxide and water vapor.
The reed valve prevents reverse air flow through the system. The PAIR solenoid control valve is controlled by the PGM-FI
unit, and the fresh air passage is opened and closed according to the running condition (ECT/IAT/TP/MAP sensor and
engine revolution).
No adjustments to the secondary air supply system should be made, although periodic inspection of the components is
recommended.

EVAPORATIVE EMISSION CONTROL SYSTEM (California type only)
This model complies with California Air Resources Board (CARB) evaporative emission requirements.
Fuel vapor from the fuel tank is routed into the evaporative emission (EVAP) canister where it is absorbed and stored while
the engine is stopped. When the engine is running and the EVAP purge control solenoid valve is open, fuel vapor in the
EVAP canister is drawn into the engine through the throttle body.
NOISE EMISSION CONTROL SYSTEM
TAMPERING WITH THE NOISE EMISSION CONTROL SYSTEM IS PROHIBITED: U.S. federal law prohibits, or Canadian
provincial low may prohibit the following acts or the causing thereof: (1) The removal or rendering inoperative by any
person, other than for the purposes of maintenance, repair or replacement, of any device or element of design
incorporated into any vehicle for the purpose of noise control prior to its sale or delivery to the ultimate customer or while
it is in use; or (2) the use of any vehicle after such device or element of design has been removed or rendered inoperative
by any person.
AMONG THOSE ACTS PRESUMED TO CONSTITUTE TAMPERING ARE THE ACTS LISTED BELOW:
1. Removal of or puncturing of the muffler, baffles, header pipes or any other component which conducts exhaust gases.
2. Removal of, or puncturing of any part of the intake system.
3. Lack of proper maintenance.
4. Replacing any moving parts of the vehicle, or parts of the exhaust or intake system, with parts other than those
specified by the manufacturer.

Hope this info helps you good luck!

THx for the information.
It's useful, but it does not tell anything about actual emission measurement related to the Rune. Any data, diagram would really help.

CARB2008 /Euro4

Hi,

just to make what I am looking for more concrete. Below is the Euro4 requirements for EEC homologation


Maximum value required EECommission for gasoline 2005 (EURO 4) (g/km)

Gasoline EURO 4
CO 1.00
HC 0.10
NOx 0.08

CARB2004

Hi Jacques,

That´s the one half of the information for making the logical correct decision - where did you get it/find it (The Euro2004 max. figures) ?
