K&N w/ watershield installation question

When i bought my 71T, it came with a awful chrome stock air housing and I recently bought a pair of K&Ns to install on my webers. I have read the posts on no real perf difference, I just want the sound and the look. I dont drive it enough to really do a lot of damage. But I have an installation question because I never get decent directions.

Once I remove the stock top air housing, I am left with the stock base mounts with the clips on the sides. Once I remove the nuts to release the old housing base along with the air horns......Do I place the new K&N filter base down with on top of the carb with the gasket and then put the stock airhorns back on top on the new K&N base?

Yes, and buy the vapor kit with hose from Richard Parr at PMO. His phone is
310-394-0088. It will really clean up all the evaporative emission control hoses
in your engine compartment that used to attach to the stock air cleaner.

Thanks,
This site is really amazing, Im going to post the step by step photo process for others in the future.

grease the filter gaskets heavily and keep it oiled

ronin can u explain that more for me, thanks.

the wheel bearing grease on the rubber seal at either end of the filter will keep dirt from sneaking by.

At the risk of being trashed about the K&N filters allow me to say that I can never find any dirt inside the filter carb top area. Some would argue that routine lab tests on a K&N filter is inadequate. That the oil on a running vibrating engine creates a vapor that captures any oil trying to pass through. If you buy into that you'll understand that oil is vey important to K&N operation.

I re-oil once a year or after one of my big rides which may be 15-20,000 miles. Another pelicanhead posted to re-oil every 10,000 miles.

Thank you, one more question. Is there anything I do to seal the paper gasket underneath the new K&N base or does it just lay as is.

lay as is

Cleaned & oiled my K&N last night. K&N recommend cleaning much less frequently than 10,000 miles, unless you're running in a very dirty, enduro-type environment (a standing recommendation is "clean if you can't see the filter mesh").

This is probably because it filters better when slightly dirty

Quote:

The unique design features multiple layers of oiled cotton fabric which captures the airborne dirt particles. These dirt particles cling to the fibers of the filter and actually become part of the filtering media.

All of our air filters are washable and reusable. They can be easily cleaned and oiled using our K&N Recharger kits as many times as reasonably necessary. In our testing laboratory, we have washed and re-oiled one K&N Air Filter more than 100 times and it still performed up to specification. We recommend you check your air filter every 30,000 miles, however, under most street conditions the filter will not require cleaning until 50,000 miles of continuous use. And yes, we’ve heard the stories of customers who ran their K&N filter for 100,000 miles without a cleaning, but we believe cleaning after 50,000 miles to be the most beneficial service life without sacrificing air flow.

... I can never find any dirt inside the filter carb top area.

1st - never use wheel bearing or any other petroleum based grease on rubber!! over time, it will destroy the rubber. use a silicone based grease

2nd - it is not the dirt you see that is a problem; it is the very fine abrasive particles that are too small to be seen with the naked eye

it's too bad they don't make paper filters for this appl. ...
