I'm interested on this as well and have been inquiring about this mod. Did you vote on the poll Zak? Sort of like the OP, did the block off help at least a little bit?Mine still pops every now and again. Had them on for a year now. They only thing these do is get the tuner an accurate air/fuel ratio reading when you get your bike dyno tuned.
My bike never backfired to begin with. I had some popping on decel. After my tune I have a pop every now and again. Nothing crazy or loud though.I'm interested on this as well and have been inquiring about this mod. Did you vote on the poll Zak? Sort of like the OP, did the block off help at least a little bit?
Reed ValvesYou should do blockoff plates if you're planning to get a tune. The primary benefit of removing the secondary air system is to allow for a true AFR reading. In a roundabout way, the reduced 'popping' is just a bonus. Reduced weight and cleaning up the engine bay are also very small bonuses :tounge2:
On another note, it is possible to do the same thing without having to buy "plates" .... by removing the valve, connecting the two "air injectors" [can't find a good name for these] with a tube and capping the hole in the airbox -- you've eliminated air being injected into your exhaust.
