Hi all
How I replaced my stock air filter for a K&N on my 2010-VT400. (Fuel injected bikes)
K&N part number is: HA-7504 to suit my 2010-VT400
Repco are the official dealers for K&N however at $160 they are also a ripoff. I got this off eBay for $74 Aud posted.
A pretty easy 2 min job but thought a posting on how I replaced my stock air filter to a K&N might help others.
As mentioned easy to do job and took all of 2 mins. Only tool required was a 4mm allen key wrench
If you have a carburettor you may/will need to investigate a few changes when changing the air filter and you may/will need to get it re-jetted or invest in a re-jetting kit.
K&N recommends that the cleaner will need periodic cleaning at 50 000miles (80 000 km) or more often in 'dusty' conditions. They recommend using their cleaner & oil or a comparable air filter cleaner & re-oiling oil
DO NOT use compressed air, chemicals not specifically designed for cotton air cleaners, petrols, transmission fluid, motor oil, light weight ooil or diesel oil fule to re-oil the filter.
Only use a recommended cleaner for cotton air filters and a recommended oil to re-oil the cleaner.
If in doubt see the cleaning & re-oiling YouTube video clip below.
Ok...
Locate the air cleaner housing on the right side of the bike about where your knee would be when sitting on your bike.
Remove air filter cover as per the work shop manual by removing the 5 allens key screws holding the chrome air filter housing using a 4mm Allen key tool/wrench
Remove the stock Honda air filter, mine was in excellent condition and looked nice and shiny and new.
With the air filter removed mop up any oil residue from the crank case breather hose. I only had a very small amount (about a teaspoon) of blow back oil.
Put K&N air filter in the same spot the stock air filter came from with the large oval hole in the air filter covering the intake oval hole of the air filter housing and the K&N logo facing out
Replace the chrome air filter housing BUT make sure the rubber gasket around the air filter housing is nicely tucked into its channel so the the chrome air filter cover seals against the air filter housing on the bike.
Lightly tighten the 5 (4mm) allen key screws by 3 or 4 turns and then once they are nicely started then tighten them up.
By lightly screwing the allen key screws in by 3 or 4 light turns you don't run the risk of stripping their threads.
That's it.... enjoy the new found power of you bike.
I installed my K&N air filter last night and this morning I noticed a marked improvement in my bike acceleration and general performance. I don't have access to a dyno so I cannot compare the stock air filter to the K&N however, I noticed a marked improvement in my bikes power.
Usually I'm getting up to speed slowly from when I accelerate from the 60Kph zone to the 80Kph zone sign just before the small hill near my place.
However, today I was quite surprised when I accelerated as usual not really expecting anything different and the bike accelerated quite quickly so that I had to throttle back at the 80kph sign where I would usually be still on the throttle and increasing at the same sign!!
As mentioned, easy as pie job but always good to know others have done it and it's not really worth paying a mechanic to do this job (sorry the the bike mechanics out there... but really, this is an easy as job)
Cheers, Pete
