For those of you that are experienced high altitude riders......
I have a new SJ. I'm in New Mexico and will be riding mostly at 4,500 feet elevation. I'm trying to determine a starting point for tuning. I'm not a mechanic, and fairly new to this. Unfortunately, finding help from someone who knows what they are doing around here is limited, seeing as it is the desert and all.
Mod List:
ada girdled head with 33cc domes that should put me around 175psi at this elevation
Factory B Pipe
MSD enhancer
MSD spark coil
Flame arrestors
Boysen Carbon Reeds
Hooker 10/16 impeller
I have the screws on the Head Pipe set as follows: top = closed, middle = closed, bottom = 3/4 turn open
The carb jets are stock.
It has been suggested to me to leave water screws on the pipe set as I have them
To leave the factory carb jets in place.
To set low carb screws at 2 1/4 turn out and to set high screws at 2 turn out.
I put around 12 hours on the stock machine at the end of last season. I have not yet fired this up with the mods.
Does this sound like a good starting point? Anyone have additional advice?
Thanks ahead of time!
