I started doing maintenance on my new/old bike (only had it a week 1988 GL1500)
these GL1500 have allot to take off to get to the Air Filter ie: seat faux tank cover.
When I pulled the filter, It was really bad, completely pluged, with the usuall butterflys and moths and 1/4" crud on top of the filter media, that explains why it was running rough.
went on line to Bike bandit looked up OEM air filter $36.00.
I dont want to get into a debate but we have all heard the negative's about K & N.
BesidesK&N's are $73.00ea. plus cleaner & oil sprays. thats two OEM filters, & almost Seven of the Napa filters (7ea Napa filters = 84000 miles)
the service manual says they last 12k miles. Hmm!!
I knew that neither of those were going to work for me. I was looking for a "cheap upgrade", that would filter at least as good as the OEM does.
I took the old OEM Air Filter, cut through the paper element up close to the air filter frameall the way around pulled the old paper elementout, then I had the old air filter frame.
I took theAir Filter frame (after the filter was removed)to Napa to see what would drop right in to that cut out.
I found that Napa part number 6425 will fit in the frame.
I used a tube of shoo goop (Walmart$4.00 a tube 1 tube will do many changes) to seal and mount the new filter to the old OEMframe put a small bead of shoo goop all the way around filter put into frame and set it aside, do an oil change or another maintenance item afew hours later it should be dry.
Napa # 6425 $9.70ea. Napa has WIX build their filters for themyou will notice more paper than the honda unit(more filter area)and Much more paper than those cheap Fram units.
Napa $9.70ea. + $1.00 sealant
Honda's $36.00ea. I could buy 3-1/3ea. Napa filters for that price,by the time I spent $36.00I could drive 40,000 miles with the Napa filters. 3-1/3 Honda filters would have cost $119.88.
K & N $73.00ea. + Cleaner spray $? + Oil Spray $?, I could buy 6.82ea. Napa filters for that price, by the time I spent $73.00+, I could drive 81,840 miles with the Napa filters.
I dont like using the K&N product for my vehicals because their claim of up to 90% efficency, allot of people like K&N and have no problems, for me I want full filtration not 70-80 or 90%
I am paying for filtration thats what I expect not an extra 5h.p. maybe, and then not do what it was designed?? for or what Iam paying for. Is that bait and switch, or smoke and mirrors?
Just my cent & half (sorry it's all I got left)
