Caughing
I recently installed a Ness big sucker Stage 2. I was previously running a Ness stage 1. Do you guys think the larger air cleaner would cause a cough after a steady cruising pace and then rapid acceleration?
RE: Caughing
Like a stutter cough? Like you are cruising along at 60 (2500rpm ish) and you quickly roll on to pass another vehicle? Something like that? Sounds like a tuning issue, running rich backfireing out of the AC (like you would have with a carb when it loads up).

Cough??? You mean a back-fire thru the cleaner???
I have the Ness BS Stage 1 and mine has done it a few time on a hard accel after a longer run...

RE: Caughing
I think the Stage II is recommended for larger motors. The Stage I is recommended for the stock motors. That could be the issue, but I don't know what size motor you are running.

RE: Caughing
I've got a pumped up Merch Performance motor and had it Dyno tuned recently (not since installing the Big Sucker). It feels like a it is possible not getting enough fuel. No backfire through the carb. Do I need to have it re dyno tuned. When I had the tune I also installed a new Power Commander lll USB. Maybe I can just tweak it alittle and see what happens.
