Boost boottle or not?

[Dynomite]

When we mounted the motor for last season we skipped to put that on, so does it make any difference or is it just some lame joke??

Talking about a rev 440 -04.

someone might have an idea??

From my experiences with them, they do not make a huge difference in performance, or any real gain for that matter. What they do is keep the carbs more balanced and seemed a little easier to keep them in tune. Wouldn't hurt to use them but don't expect a huge performance gain.

yea, no really big gains... i had one on my 05 polaris 800, it helped balance the carbs and made the throttle crisp!

[Dynomite]

okey thanks guys!

Depends. If the carb boots are already punched out for the boost bottle you need to install it or plug up the holes! If not, I would not bother. No noticable gain imo.

We plug them on the grass sleds. Also plug them on the trail sleds. My 04 800 them, now I have a rubber plug installed. Once the carbs are set with mercury sticks you will not need them.
