just got a 02 700sp runs fine down in the valley but took it to the mountains today and it started to pop and not run very good does that sound like jetting or should i look at something else by the way its all stock thanks.

 

Its jetting... stock jetting is only good from 0 to 3000 feet

 

do you know whats the stock jetting is and what my jetting should be for about 3,000 to 7,000 thanks.

 

the stock jetting in the 2002 model is 162.5, in later years they went to the 155 main.

So you are already on the rich side and getting worse the higher you go , the manual says to
go to a 140 for temps over 40 F and 150 under 40 F and at 6000-12000 ft.

Also the clutch weights should go down to the 20-54 from the 20-56 for same temp conditions and at 6000-12000 ft. No spring change.

well i put in a 145 main it had a 155 in it it runs fine but when you come to a stop it sounds like the right side is not firing it makes a tiking noise but when you rev it up it goes away and then comes back when it is sitting there idling and sometimes it wont do it at all im thinking i got a lemon any help thanks.

 

These motors make a loud ticking noise, i have a vid clip of my silencer but you can hear the ticking.
Check the plug boots, it may have poped off one cylinder plug.
