How do I fix backfiring in my motorcycles air filters?
I have a 78 yamaha 1100 with upgraded air filters instead of the air box but it seem to keep backfiring in the airfilters. Any reason why this is happening? or how to fix would be awsome to
Backfiring through the intake = running too lean. Sounds like you've improved the airflow, so you need to go up a size on the jets.
