2023 boost sputtering at break in?

[J40]

New to Polaris ,coming off ski Doo summits my whole life just received my 2023 boost 165,drove it for first few hours yesterday and it sputtered at wot? Also the throttle was sticking a little till I hit the break,not every time but often. Just wondering if this is normal for the boost at break in?

The throttle sticking has been a common Polaris issue for years. Welcome to the club. Usually its from ice buildup in and around the throttle block. I've also seen issues with the cables themselves being run poorly and kinked, or the sheathing inside the cable causing problems. Any slack in the cable can cause runability issues with the TPS, but usually it just kills the sled. I suppose that could be related to the sputter.

Make sure your fuel setting is right. 88 ethanol or 91 non ethanol. On the 7S Push the polaris star while it’s running then in the upper right you see the two fuel options. That made a noticeable difference in how my sled ran during break in and after. By the way, I’ve had my fuel option switch on its own unless I touched the screen while riding and didn’t realize I changed it. Worth checking that setting now and then.

Put the stock can back on…usually the problem

I've tried to tell people this and they just can't stand it. They just refuse to believe that a performance part will cause performance problems.
