I am going to the cabin for a couple of weeks in the SanJuan Nat forest in Southern CO and need to know what jetting changes - or which jets to use at that elevation? 9k-12k+ft

I have never changed jets before so keep that in mind.

Thanks and have a good one,

 

sounds like you would be a good candidate for Dial-a-jet......

 

I dont know if I should thank you or cuss you.... HAHAHAHA

O well - maybe someone else has done this - and from what I have read - I think 155 mains should be good enough? or do I HAVE TO jack with the needle?

Over,

 

Do you have mods on your bike or is it stock ??????? If stock then you might have to go lower them the stock 140/145 and leave the needle

 

Yes - I am all stock - well I have a foam filter... but thats it...
