Patrick...why Loopless?

I remember you mentioning (or someone) this before about the venturis.

I don't disagree with the "flow" theory of things but I have had the K&N's
on my 69 now for over a year. The bike starts well....idles well.....runs
well too. The plugs are nice and tan and I get 50+mpg.

Rode the bike to Virginia last year without a hiccup.

Not to disagree with you but if I am slowly doing damage to my engine I
would like to know. Any thoughts from others on this? I haven't noticed
anything.

I have thought about swapping the filters on both bikes (the KN's from 69 to
70 and UNI's from 70 to 69) just to see if I could notice a difference but
both run so nice now I don't feel like going to the effort of swapping. I
feel like riding instead :-)

Regards...Ian

Ian and others. Do NOT abandon those venturis. Correct, the K&N's won't
mount over the venturis. The venturis have lips to hold the original rubber
air boot. However, these venturis are VERY important for proper airflow in
the carb, easy starting, high rpm, good fuel mileage, etc.

So, you need to unscrew the venturis and take them to some machinist friend.
They will quickly lathe off these retention lips on the outside so the K&N's
will fit OVER the venturis.

Re-attach the venturis and add the K&N's and you'll be happy. I rode a 73
Eldo for probably 8 years with K&N's on the carb body. Someone finally
turned me on to the proper installation and I was amazed an my totally new
motorbike.

Loopless now.
