RX1 mountain jetting and clutching from factory?

[inferno]

does anyone know how the 03 rx1 mountain comes from the factory? i am riding a factory 03 mountain at 600 feet above sea level.

My shop manual says, main jet 135, needle jet p4m, pilot jet 17.5.

Have fun,

Here ya go straight from the 2003 service manual:

The mountain sled specs are on the lower grid.

looks like they come from the factory the same as the regular rx1 with 135 mains. what is p4m?
thanks

P4m is the needle jet, that the jet needle, AB-3 slides up and down in when the carb slide (yamaha calls it a piston valve) goes up and down.

Hope this helps you out,

Yup, like 4-play said:

P4M = Needle Jet
Ab-3 = Jet Needle

They are model numbers.

The rest of the specs are on the following page:
