K & N Air filter

hi all
new to the forums and new to harleys,just managed to get myself a 2003 1200c sportser. i want to do a stage 1 on it and have got some cycle shack slash cuts on order aswell as a jet kit.just wondered if a k & n filter insert will let the engine breathe enough or do i need a SE a/c kit.

cheers

The K&N filter will help the engine breathe easier but you should also drill vent holes in the backing plate (OUTSIDE of the air filter element). If you're not sure what I mean find someone who has had a "Stage 1" completed "free" by their dealer. You will see a series of holes drilled through the plastic backing plate instead of fitting a SE air cleaner kit.

hi
thanks for the reply. can anyone post a pic of the modified backing plate please.

Hi mate

I fitted a K & N filter plus earlier longer breather bolts to my 2001 Sportster filter set up and had had no probs since.

Try PM’ing ‘Folkie’, if I remember, he got a pretty decent set up from the US and got a good price.

Give him a try, he’s a good ‘un.

Cheers

well i have just received my k&n filter today which i got off ebay,it was listed to fit 1988 - 2003 but is completely different to my existing filter.i have checked the part no. hd - 1388 and it does state 2003 model, but the fixings are completely different.is it possible the late 2003 models had the 04 design backing plate? the part no. on my filter is hd 29261-95 01 - 03.can anyone help please.

The filter you need is this....HD-1396

Cross ref number for 29261-95 is HD-1396

See this link
AMERICAN K&N APPLICATION LIST





I take it you bought this....HD-1388



Which if you want to fit it you need a filter set up like this....

You could try pm'ing Borg.
He's just sold his Sportster chop and I think he had recently fitted a Hypercharger.
So he may still have the one shown.

You will need the 2 earlier breather bolts, the 2 long spacers (which go in-between the air filter back plate and the cylinder head), 2 short spacers and 2 locking washers (which go in-between the bolt head and the air filter plate, shown at the top of the filter plate)
Also the 2 threaded 'air cleaner cover' mounting 'spacers (bottom of picture,which pass trough the filter and allow you screw the cover to) with the two bolts and lock washers which hold these 'spacers', plus the plate of course.

Cheers
