If you have not been there, www.dootalk.com has a wealth of information for your sled, and lots of friendly people. They do pack the new sleds tight. Get the longest most comfortable Phillips screwdriver you can find. It will be your new best friend. About 15" long should do. Then you can reach deep in there to the second carb. I would give you specifics but i am more versed on the ZX and XP as opposed to the REV.

Most are pretty simple the carb linkage should have a small moon shaped disc with three or four small adjustment holes for the bent tip of the throttle cable. After attaching the cable to the handle and snaking it to the carb. There is a small clamp that will hold the cable in the adjusted position .slide the end under the clamp and then connect to one of the holes on the linkage..slightly tighten the clamp and slowly move the handle unti the handle goes the full travel..then check to see it the carb linkage goes to full throttle and backs off to idle..if it does not..loosen the clamp and keep adjusting to get the desired full throttle and idle..May have to play with it a couple of times but it will adjust..good luck..
Please check the following:
- Throttle control cable adjustment.
- Foreign matter in throttle plate.
- Fuel line clogged.
- Water contamination in fuel.
- Vacuum leaks in the intake manifold or at the carburetor.
- Carburetor base gasket or seal.
- Air/ fuel mixture adjustment.
- PCV valve.
- Valve clearance.
remove seat and side panels to gain access to everything. unbolt the airbox there should be three or four bolts and atleast one is going to be hidden. loosen clamps on air boots from airbox to carbs and slide back air box. it might only move an inch or two but that is all you need. unhook everthing on carbs and loosen clamps on intake boots. slide and wiggle back on carbs and you should have enough room.
I have a 2006 Sportstman 500HO ATV, EFI. Sometimes it will run 100% correct, other times it will start, idle fine but then when giving it throttle will will start to surge almost like it's hitting a rev limited. Sometimes it will backfire and stall. I already replaced fuel filter, flushed the fuel lines and gave it fresh gas and installed a new spark plug, but no good. I also checked the throttle switch and it's not making contact to stall it. I download the service manaul and tested each sensor and they tested fine which is probablt why I get no check engine light. This ATV is mainly used to plow snow in my driveway, no salt. It's used around my property but very lightly. It's still as clean as it was when I bought it and it doesn't have but about 40 hours on it.

well how long has bike sat do u have to leave choke on if bike sat all winter and u cant take coke off carbs need cleaned if bike has not sat then look for vacum leaks by sprayin starting fluid around carb and air box if it revese high then u need to fix the air leaak problem by new boats or clamps
The timing is not the problem. Air getting into the fuel mix AFTER the carburetor is the red pipe problem. Bad carb seals, loose clamps and fittings and old cracked hard rubber all can lean the mix and make the bike run hot. As to the carb, I would take it apart again and soak it for 30 minutes in denatured alcohol. Then use spray carb cleaner to finish up the cleaning. Be sure to spray into all carb circuits from both ends and pay special attention to the throttle and air screw holes. The setting for both screws is one and one half turns outward from a LIGHTLY seated position.
