I have a 2010 as well. Elevation is 800 feet. I run 350 MJ with 96 octane. If it's any colder then 0 degrees I bump up to a 360. You need to figure out what type of fuel you will be running, that will vary jet sizing a lot.

If your going to run pump 91-93, 390s on g/f will be fine. Use the search function, a lot of threads about jetting and other trail related notes. Read up and learn, you'll have a blast on the IQR!

Does it bog or gurgle in midrange?

You have to remember ,its a race ported engine,they have shitty midrange and just isnt going to have any power there.Same as the old 440 but way more power up top.

Yea it gurgles in the midrange. I know it’s a race sled like everyone keeps saying but I wouldn’t or couldn’t hit 20 ft double with it like this it wouldn’t even be fair to race it it’d be so hard to even get around the track like this.

I’ve talked to a lot of ppl that have had this sled or had them and they all say there’s was good from bottom to top no issues. You’d die if you tried to jump this thing lol
