Friend gave me a slp boost bottle for my sled 1999 pol 600 big block stock pipe aftermarket can. May pipe it over the summer.
One friend says i'd never notice the diff,, might cause air leak
while another says huge diff especially in mid range

Tell me your experiences should I run it ??? Thanks

One very good mod you can do to that sled is to put a CDI from a 97 700 rmk on it. The difference is very noticeable.

All the 97-01 600-700-800 will run smother off idle and in the 1/4-to just over 1/2 throtle range with it . You can tune around it with out it but it takes a lot of time . By the way all 97 700 had the same timing curve and the 98 xc has that box as well

Thanks

Thanks for all the INFO I'll think I'll try it! If I dont like it I can always plug the holes back up!

I'll look into the cdi, I'm not sure how to do a side by side comparison with it other than it peaks out at 8K rpm.

Thanks again !!!!!!!

Just be careful.. when it cracks, you will burn down the motor. It wont be if it cracks either.. it will be when.

38 pilots and 1371G needle in #3 and jet it 2 sizes leaner on the mains than what Polaris recommends.

Watch the float pins as they egg out the holes. Pins from a 2000 are knurled.

What the bottle does is equalize cylinder pressure. You really shouldnt have to rejet with the boost bottle. Just adjust your fuel/air screws.

I run 5500 to 7500 and have been told to ditch my keihin carbs and go to mikuni's on a rail.told the keihin wear out baddly. so might try that wrought where I just trashed my throttle cable zip tie broke and cable got under the steering stopper Not good. Summer project anyway Im going to a 121 2" and fabb'ing a 2006 iqr seat. I raised the bars by putting on mountain max bars(really nice bars).

This sled is so much fun to rip and zip even in 1' of powder and blast through the trees then rail of off cornices I keep parking my dragon and riding this!!!.

I wouldn't run it IMO it is just another place for a air leak
