Ok I have the 07 roadglide trying V&H slip-on ovals.
K&N a/c PCIII.
I have been getting a lot of popping on decell and a little when
accelerating 1st-2nd.
I went in and had the dyno tune the bike runs OK on the open road.
But I still get the popping. I checked for leaks around the clamps and
everything seems OK.
I tried adding and removing fuel in first column on the PC software.
Nothing helps.
So I put the stock cans back on went for a ride no popping.
Why?

Thanks
