Hey i got a 1999 rmk 700. I live in alberta around 2200ft, in the mtns we go around 6000-8000 ft. running 185 mains with a blue primary spring an silver/blue secondary. i was told to run a red primary spring with the stock secondary on the 2nd hole aswell as 58-62 primary weights. i do have the accs hooked up an i can only pull 7400 rpm
Yes another jetting question

Try an almond primary with 10-58 weights. Use the stock silver/blue 2ndary spring and find an R8 helix, you probably have a R11. Your way rich on the main jets, stock engines used 165's I believe, I was running 175 mag and 172 pto with twin pipes, heads etc,etc at 5000' to 6000' Be real carefull jetting it down, just cause you read it on the internet doesn't mean the guy saying it isn't an idiot. Good luck

At those elevations, I run a Polaris blue spring with 58 weights. The secondary has the silver/blue spring. Keeps my rpm at 7900.
The stock helix is the R11, 45/36. The R8 is 50/34. I tried an R8 and it didn't perform, maybe the conditions we were in that day. But I prefer the R11.
As for jetting, 185 is way too rich for up high. I'm pretty sure i was running 175's at 2500ft. I'm going to dig the machine out of the garage in the next week, so I'll double check those jet sizes.

As the ACCS gets old and begins to fail, which it will, it goes rich.
Chit can the ACCS, plug the extra vent on the right carb, then vent into the airbox like an 00' SKS 700.
Stock motor:
run 145-148 for mains for 6-9K
38 Pilots. you may have to play with the airscrew with big temp changes but it is worth it.
1371G needle in #3 for cold days and #2 for warm days.
Almond round in the primary with 58's if you can pull 8200 on the tach as they almost always read high.
Leave the secondary stock but run it in #3 with a new spring.
