2000 sxr burble (700)

what is the easiest fix for the low speed burble??? Reed spacer? I have adjusted the fuel screw to 1 turn to 1-1/4 turn, helps but not perfect. Its the wifes sled so it gets driven slower than it should and in warmer weather 30 degrees and I am sick of hearing her whine its not as smooth as it was....like......when it was 10 degrees out!!!

Doing the reed stopper notch helps (reed spacers do the same thing, but the stopper notch is free and its on the tech page). Also dropping your needles 1/2 clip will clear it up a bit too. Mains on that sled (if they are still stock) can also be dropped some to get a little better mileage and cleaner performance on top end.

top end is great 115 mph on speedo with wife on it!!! Just hates being run slow tooooooooo long. I think I'll try reed spacers, Id hate to mess up the reed cage!

I was concerned about weakening the reed stoppers also.It seems like I remember a couple people having failures with this mod last year.I think I'm goin with read spacers when I have it apart for rings next fall.

Ya I found a new/used set on here for $45 w/shipping so I'll try that. Between that and turning the fuel screw in a 1/4-1/2 turn it should help. My 700 twin polaris did this and after a boost bottle, reeds, and venturi spacers everything was fine. That cost a few hundred to do so hopefully this helps!!!
