I am looking into purchasing a K&N air filter for my stock 1997 VN750. I can't find any sites that specify that the 70 dollar filter includes both parts. Since this bike needs a filter on each side I want to make sure the price includes both filters before I throw my money away. Can anyone help me out? Thanks

Yes, you should get the set. I believe I ordered mine straight from the K&N website.

Ok thanks. I wasn't sure if it would send me both or if I was going to have to drop $150 on air filters. I need all the extra money I can get to have my carbs synced this year :(

I personally don't recommend K&N air filters, because I don't believe they filter as well as stock. They are also designed to flow more air than stock, which means you will have to rejet the carb to compensate, or you will end up with a too lean air/fuel mixture. I have found that my completely stock Vulcan 750 (engine wise) has plenty of power for my needs. K&N filters combined with an aftermarket exhaust and carb rejetting will make slightly more power, but very little. Most people replace the exhaust for the sound, I never did figure out what the K&N filters were for, if you are keeping the stock airbox. Jerry.

I know the feeling. You can do the carb sync yourself. It's really not that difficult. I believe there is a part in the Verses on it, and I'm sure there are a good hand full of people on here that could help walk you through it. It will save you lots.

I have not rejetted and have not had any problems out of mine. You don't have to rejet, you may need to adjust your fuel mix screws out a turn or two though. But each has their own opinion.

Yeah but there are a ton of other issues with this bike so im just going to have the shop do an overhaul. I am it's new owner and the guy I bought it from stored it outside and uncovered. He put aftermarket pipes on it and never rejetted the carbs or adjusted anything. It ran so rich the engine built up a lot of carbon and it needs new lifters and valves as well as a good carb cleaning and jetting. The bike only has 7k miles on it so after I pump a few hundred in the engine and dress it up a bit I will be another happy VN750 rider :motorcycl

Ok, you didn't mention all the other issues. Both K&N filters and an aftermarket exhaust will make the bike run leaner not richer. Anything that makes more air flow through the engine will lean out the A/F mixture, whether it is a less restrictive air filter, or a less restrictive exhaust. Both together will make it even leaner. It is very possible the previous owner did rejet the carbs, and over did it. I live at 1200 feet, have the stock filters and exhaust, and still had to turn the pilot screws out a full 3 turns to make it run right.


Remember, when you have a shop work on a bike, you will be spending most of the money on labor, not parts. I would do as much of the work as you can by yourself, though I don't advise anyone without considerable mechanical skills to remove the heads. Too much chance of messing up the valve timing.

One last thing, you said this bike was stored outside, and implied that it had not been very well cared for. I would make sure you think this bike is worth putting money and work into. There are a lot of really nice late model low mileage Vulcan 750s on my local Craigslist, for very reasonable prices, mostly due to the economy. A lot of people around here are out of work, and are trying to sell off their non essential things in order to feed their family and make their house payment. I can barely resist buying one myself.
