intermittent bog

[wi.switchback]

i have a 2011 sba with about 1800 miles on it,took it for the first ride for the season and about an hour into the ride running over some heavy moguled out trail i noticed a bog every once in a while,it seemed to happen when i was on and off the throttle fast,when it would bog i let off completely on the throttle and got back into it again the bog was gone it only did this maybe 5-6 times in a 7hr ride!now i had a full tank of fresh 92 in it and i've religiously run the recommended amount of startron,now i'm not a dummy with motors or carburation but this fuel injection i'm just understanding so if anyone could give me some opinions on this i would greatly appreciate it.

Check your throttle cable for excessive play. Should be very little play. Mine did the same until I tighten it up. The adjuster is in the cable right down from the flipper.

lognomore i did that on the trail thought that was the problem too,i'm at a loss with this

Did you have the fuel injectors replaced? That was also a problem on some if the 2011 earlier builds.

no i didn't i was not aware of the problem!thats going to be a good place to start cause thats where it seems like the problem is,in the fuel dept. i just picked up a fuel filter, i wonder if the injectors are a recall?

 

[lognomore]

Injectors were not a recall. There are a couple of other things to check. One is the throttle position sensor plug on the throttle body. Pull the plug, check for moisture and put some dielectric grease on the pins. The wires going into the plug should have silicon on them to keep moisture out. Takes very little moisture to mess up the connection there. Also look at the wires going to the injectors, look for bare spots on them. Vibration will chafe the wires if they are not secure.

i will go over all that today!i got my friend coming over with the box to power up the tps to check that,i also checked out that i have the blue injectors and i see they should be changed out to the yellow updated ones plus a reflash

Similar problem here! Falls on its face for a split second, happens now and then. WERY annoying!!

i found out that its an injector problem, if you have have the blue injectors have them changed out to the updated yellow ones.
