Air Filters

If I put K&N filters on my stock vn750, will I need to make a carb adjustment?

Has anyone done this?

Thanks

No mod needed if you use the OEM drop in K&N that replace the factory ones. Just installed mine last month. I like K&N and use them on my cars.

Here is the K&N part number for the OEM drop in. I paid $58 on Amazon with free delivery last month.

It's up to you if you want to use them. I don't feel they filter as well as the stock oiled foam ones, since they are designed to flow more air, which would in theory anyway lean out the air/fuel mixture, but I have no idea how much. I use the Emgo stock replacements from Dennis Kirk, and change them about every 10,000 miles. I don't even try to clean them, I'm afraid I'll rip a hole in them somewhere, without noticing it, and wind up with dirt in the engine. The Emgo filters are a amall fraction of the cost of Kawasaki filters, and seem just as well made. Jerry.

I agree with Jerry 100%; K&N are a personal choice. In my case I hate old fashion oiled foam (no offense to those who know and love them). It took me 5 minutes to install the K&N, but 20 minutes to clean out the the old oil and goo left behind on the air box frame by the old oily foam filters. The K&N's are permanent, come precharged (oiled), rated at 50,000 miles between cleanings (that's optimal conditions, I assume), no rejetting (for the OEM version), easy to wash and recharge and much less mess than oiling foam. K&N's are a quality product and do have a high flow rate, but still do great job at filtering (never heard of an engine scoring or damaged due to a K&N filter).

Also, I live in an apartment with access to a shop, so its a no brainer upgrade for me; no 30 weight oil to store, no mess to clean up or make oiling foam and I don't have to open the air boxes for at least 30,000+ miles.

I assume you meant to say "with no access to a shop."

Doh! Yes, no access to a shop (or brain).

Thanks for catching that
