Kerker inserts


Kerker inserts

Postby Rick Pope » Wed Aug 27, 2008 2:36 pm

I pulled an old set of Kerkers (6-2) from the barn, polished them up a bit, and slipped them on. While fitting them to the bike, I looked into the end and saw......nothing. There's an aluminum end cap, but a flashlight reveals much emptiness in those megaphones.
So, my question is: Does anyone know of a source of Kerker baffles? I know they made a "Q" (quiet) baffle, and that's what I'd prefer, but I doubt I can be choosey.
Meanwhile, I guess I could take it to the local Bike Nite and show the boys what "loud" is......

Hey, Rick, it is always good to save a few lives.... :roll: :wink:

BTW, I read elsewhere that you decided to leave the stock airbox on the CBX and NOT use pods or individual filters. Smart move.
A - CV carbs do not like filter pods. No matter what the "performance oriented" want to tell you! :roll:
B - The Honda engineers supposedly designed the air intake such that the length of the individual channel in the airbox compensates for the unequal length of channel between carb and combustion chamber.
I go with that and keep the stock airbox on my CBXes also.
To be understood is the exception

I must be saving a lot of lives with my wire wheeled CBX. The baffles ID is larger then the header pipes.

Got the bike together this afternoon. Same old story, runs poorly until it gets to about 3k, starts clearing up, and when it gets to about 4500 it rips. Well, okay, for a stock CBX.

I took out the carbs and cleaned them because of this same issue. Found several plugged low speed passages. All is clear now, or so I thought. I sprayed Berryman's through all the passages and had good results, but still have that stumble at low rpm. It idles fairly well w/ the choke on, so I'm sure I have a restriction somewhere.

BTW, the empty Kerkers get nasty looks from the neighbors.

Checked out Terry's link to Kerker baffles. Looks like an inexpensive alternative to original Kerker baffles. But the original baffle is much longer, and probably quieter, than the cheaper alternative.
I'll probably bend some 1 1/2 conduit and cut a bunch of slots in it, wrap it well, and see what I get. Then, after 1/2 days work, I'll probably spring for the baffles Terry's suggested. It's gotta be better than empty cans. Did I mention this thing is LOUD?
