| There isn't a manual enrichment on the fueling as such.
The "choke" simply cocks the throttles open a little and from this, along with the air, engine temps. The ecu fuels it accordingly.
If it's only happening once the engine is hot, then I'd suggest the fuelling isn't set up correctly.
Any "cold" conditions would cause some form of enrichment and this may be masking the set up inaccuracies.
Simple checks to check the colour of the plugs and exhausts could show it is running a little weak??
Also, the factory settings are usually in accordance with emissions regs. These are, as a rule of thumb, too lean for optimum runnng. They seem to run best at somewhere between 3% - 6% CO. For what it's worth, 4.5% is my usual preference.
Might be worth a chat with your dealer? |
