Street Scrambler Bog

2018 street scrambler bogging at low revs and high revs.any ideas? Only under load. Air filter good. I have a decaf and Vance pipe. Decay was installed last year. No problems with my bike till yesterday’s ride. Bog didn’t start till 35 kms into ride.

 

Decat **

 

Regular use. Can’t see a blockage. Like I said, ride started out great then boggin.

 

Ignition breakdown. Changed the plugs and it runs like it’s supposed to again.

 

Hey hey
