Which Jets???? Please help !!!

[BO4RE]

I bought an 04 RX1 and it came with open air filters, for each carb. Anyway, it currently is running 160's for jets, I assume that is huge, even though the previous owner ran in the mountains alot. So that being said is their anyone else running this size of jet. A chart with some corresponding elevations would help. The guy I bought it from said because of all the extra air from the open filters meant big jets, what do you guys think? I'm not going to be riding the sled this season as I am selling it, but i'm still curious.

ECP kit

I assume you have an ECP kit on the sled with filters. Their specs are for 165 at sea level for jets and I have read in a post that you can drop to a 160 or 155 when in elevation using their kit. If you PM Supertuner or repost this in the 4-Stroke Tntake thread he will respond.

It sounds like the previous owner knew what he was doing. The 160 mains are about perfect for the occasional juant to the mountains and some mid elevation work. If you run sea level go with 165 mains.
I also found that raising the needle one click also help ed get rid of the burble associated with running the open K&N air filters.

Good luck
