K&N RK-3929 HI FLOW AIR FILTER.
Need some advice, just imported ths filter from the USA to the UK for my 07' 1200C.
Enountered a problem when fitting the the filter.
I disassembled my filter, removed the stock breather bolts, and began to assemble as per the K&M instructions I'm good at that ask my other half...!!)
I inserted the new breathers assembled the filters back plate and velocity stackand then offered the assembly to the body of the carb.
I loosely fitted the stock breathers and then methodically screwed in the hex bolts to the carb and then eventually tightening the breathers to secure the plate.
My problem is i have a gap between the back plate and carb body, I cant overtighten as this will bend the aluminium backplate.
My guess is this shouldt exactly... I have done something wrong..? I dony have any 'left over' pieces... I'm at a loss..
Any suggestions...?

How big is the gap?
Just looking at the "destructions" I would say to check that you only used 2 washers on the breather bolt extensions (not 4) and that the velocity stack is installed correctly (from the front, not the rear). Otherwise you may be needing a thicker gasket.

I guess the thicker gasket is probably the right route. I actualy removed the two washers from the fit - still didn't give me a flush seating.

Hey Brigger, if you can get your hands on the april 08 issue of American Cycle, you can find a Tech article on installing the K&N air cleaner filter , starting on page 28. Shows step by step installation of the cleaner on a sportster with lots of pretty color pictures. Good Luck mate

I had the same problem. The gap is about 1/8 of an inch and it's because of the two metal cylinders that stick out of the filter. You can grind them down a bit with a dremel. I didn't yet... I just got the cheap $24 stock filter. I know.. I'm lazy...
