I don't seem to find any discussion of jetting in this very informative thread. I live at 6200 feet and will probably never be below 5000ft when camping. I would like to install high altitude jetting, anyone else?

I just spent a half-hour looking for an e-mail message from a poster on an innovative way of jetting leaner. I can't find it but do remember enough to give you a push.
Anyway, he had a set of machinist's indexed (numbered) tiny drill bits. He took the OEM jet out and found the drill bit that fit the opening - made a note of the size (part I do not remember). Next, he soldered the jet opening closed then carefully re-drilled it with a smaller bit (again, the size is what I can't find).
I have also been told that CPE has a "jet kit" but I am not sure if it is leaner or richer - I'm inclined to think it is richer and was offered as a possible cure for the "burp".
What would be helpful is to have at least one spare jet, two would be even better. Solder them up, re-drill and have them available for a speedy switch-out for high altitude testing.
Another way to
test if a slightly leaner mixture will help is to remove the OEM air filter element so there is a lesser intake restriction. Not a good idea for dusty or pollen laden environments - but maybe OK for clean mountain air?
If you want to talk to a man that
really knows these things inside and out I suggest you give Fran a call at the NY SuperGen retail store (315-573-7887). Fran is a mechanic that has worked on the CPE2000i since the day they hit American soil.
