bog

My 2006 switchback 900 cuts out/bogs at full throttle. It won't do it all the time but more often than not. It has about 2k miles on it and haven't touched the motor. Anyone have possble causes for this? My thoughts are 1) the throttle body boots look cracked so maybe it's pulling in too...

Would larger pilots in 38mm Mikunis help my bog in my 1990 500? I know my clutches are good (new primary and have been through the secondary), sled was running great a few weeks ago with the colder air, but now that its warming im picking up a bog. Motor has about 300 miles on the full...

I wanted to start this thread to address the extremely too lean fuel map that Polaris dealers have been installing on every 800 CFI since the engine update came out. I have to admit when I first read the posts here on the 4m related to runability issues for the 800. In the Auto Service world it...

Been looking for a cause for my bogging problem on 1998 powder special efi.Checked everything I could find on other threads on here. I found that my motor was torquing bad when under WOT. Also found broken torque bumper. Would this cause a bog at WOT and not allow me to rev over 7000 RPM? Any...

my 05 rev 800 has been tending to bog out and only reach like 76 rpms max and my plugs are loaded and black like they are oily. anyone seen this or know what it may be... clutching, jetting, too much oil?

So, first ride of the season doing a little hill climb and the engine stutters bad 3/4 of the way up. It then did it the rest of the day at varying throttle positions (WOT, on accel or even constant cruising). It feels like it's dropping a cylinder for a second then picks back up. Also, it was...

hey guys, i have had this problem with a sled i've had for awhile but never been able to use, and it's back to that time of year! so here it it. symptoms are start and idle great, but as soon as it is given throttle it bogs and dies out. but if you manage to get it past 5000 rpm it'll run at...

I have a 2005 M6 that has a D&D m8 kit in it with a D&D single pipe and D&D can. Timbersled intake. Boondocker box. supreme tool rave style exhaust valves to eliminate that problem. It is a really great sled when it runs but last winter i couldnt figure out what was causing my problem. I have...
