kn 151 oil filter

[engineerk9]

Curious if any one has used this oil filter yet and what there experiences were. Last night I tried to use and it did not feel right. Did not go in far enough and did not seem to fit the cap good. The BMW oil filter has a little play on the end cap and slides all the way in no problems. K&n seems like it is very tight and almost a press fit like you have to press it on the pipe by tightening the three bolts. Thank you for any comments.

I'm not sure why Guys are wasting their time with the K&N paper filter - The K&P stainless filters offer better filtration, better oil flow & are cleanable - I've been using them on all my bikes for nearly 20 years - the only way to go, big relatively high performance single cyclinder motors need all the help that they can get

I've always wanted to know how you know when you've gotten the entire SS filter truly clean of 25 micron sized (~0.001" in diameter) particles. That has always been my reasoning for just throwing the whole thing away, I know for sure I have disposed of all trapped particles.

We had screens and stacked disk filters on airplanes I used to help maintain. We just disassembled them and cleaned them in the parts washer with Stoddard solvent. Those engines went 2,000 hours between rebuilds.

We spray them with parts cleaner from the inside - outwards. Then use water based degreaser, rinse with water from the inside. Dry with compressed air, blowing outward from the inside.

Tried and tested for 8k race miles on my 2004 525 and 6k on my current my05, plus all of our Zipty race and tour bikes.

That's nice, but why not take a look at this site http://www.gmtruckcentral.com/articles/oilfilterstudy.html

They do a real comprehensive and unbiased test of a whole bunch of oil filters. And guess what? The dirt they are using is 30 micron. Then on the better filters, they filter test to 5 micron.

To the OP, the tested the K&N filter pretty good at 30 micron. Amsoil and Royal Purple looked pretty darn good.

So you just keep banging that drum about how great a 35 micron filter is.

These tests are fairly good indication. It is not anecdotal musing of how long an engine lasts. This is science, not wives tales.

If you think it is a good filter use it. Anybody else who thinks it is a good filter use it. But I assure you 35 micron is abysmal. And I also assure you that in the Terra, a relatively not worn out one that is, there will be no increase in oil flow using the screen door filters.

And if you haven't noticed, the TR 650 is not an arrowplane, rocket ship, track bike, it is a dual purpose entry level bike with high compression. Any good mechanic knows that what works on airplanes is not always a good fit for a bike. How often do you run your bike at Military Power?

I shook the hand of the man who met the man who shook the hand of the man who saw Andy Griffith.

First off, how does this bring any value to the thread?

Nice comparison of truck oil filters, you almost had me excited when I thought there might be at least one stainless steel filter in there. Automotive engines produce well over 65psi of oil pressure, where as motorcycles are closer to 30ish. Motorcycle media filters are much thinner to be able to allow them to flow easier. I remember someone else on a forum trying to compare my filters with fleet oil filters that continuously cleaned the oil with a separate pump. Where is the comparison for motorcycle filters? So what is a TR650, it is Mototalia's hopped up race version of the GS650 with eight more hp. More power, more heat. You haven't seen any cooling issues with the TR650 have you? Those engines need all the flow they can get.

It has become apparent to me that you are now grasping at straws to disprove something that is already proven. That's abysmal.

 

[mag00]

You are correct, it is already proven that 35 micron is abysmal.

What concerns me is the filters are made in China. I am sure they have an acceptable level of quality control, but I will support a USA made filter. It's just my feelings. Support companies that support our sport and companies making products in our country.

 

[drzcharlie]

Hmmm, doesn't that make it a rather short list?

Electric
Brammo, Zero
Sport Bikes
Buel..(well kinda) Mission R (soon)
Cruisers
Harley, Victory, Big Dog, Sucker Punch Sally

I guess Brammo and Zero make dirt bikes the list is small.

That was gone along time ago for a bike. But an oil filter, please. China, give me a break. They are communist controlled.

I guess I should keep my comments to myself.

So is California, in case you haven't noticed.

.

....and produce the engine that the oil-filter belongs to.
Remove all Chinese made articles from the shelves of the non-communist world and you won't find a Costco/ Harbour Freight/ Kmart or WalMart within 500miles.
Welcome to the New World.

I like Chinese food.

Back a few years, there was a big uproar over Japanese stuff. After China modernizes and unions force product prices up, we will look to yet another developing country to produce cheap goods.

You have to love the free trade industry, Silks and spices from foreign lands, And they even found Indians in the Americas, go figure.

Honest I wasn't busting your chops. Sorry if I came off that way. I was just trying to make funny.

You musta missed the bit where China turned into a capitalist nation of Mercedes driving billionaire.

Just for info.

K&N and Hi-Flo are the same company.

The 2 filters are exactly the same but the Hi-Flo is cheaper. The only difference is the look of the box it is packaged in.

well they are cheaper in my area.

Hi-Flo # is HF-151 go figure.

Based upon this I bought some Hi Flo HF 151 Filters for around $4.50 each when I was in the UK last month because at $20+ each the K&N ones here in Philippines are way overpriced and nothing else seems to be available.

Interesting...and when I pulled my OEM Filter on the second oil change at 4550 km guess what I found as fitted by Husky?



The original filter is marked HF 151 exactly the same as the new one and of course the new one fits a treat with no O-Ring issues too.

Fortunately I have two more new ones which means there is no need to pay for K&N or BMW at all.

That's what K&P said. When testing against paper in average particulate reduction, their stainless steel filters had a 4 micron paper equivalence. For real world testing, Ty's 501 racing engine went through 59 hours of hard run time and was torn down to find zero wear. My KTM 500 has had nothing but K&P filters and has over 6000 race miles.

My Suzuki GS1100G did 175,000klms, my ZRX 1100 over 124,000klms, my Laverda Ghost over 14,000klms, my Suzuki 750 over 11,000klms, my TR650 OVER 17,000klms all on K&P stainless filters, most of the hydraulic systems that l work with use Stainless filters on the pressure side

K9, whats your cleaning method? for these filters. Can you see if youre done a good job? I was toying with the idea but you need two per bike? The dealer advised against using them, but thats no biggy

Hmm....so what would be the advantage ? The only one I can see is environmental.

My maths says using a stainless filter is not really viable, particularly as you need 2 of them.... as follows:

Lets say they cost $80 each inc shipping etc and my Hi Flo 151 cost me $4.50 each.
So for $160 I can get 35 Hi Flo filters and if I change them every 5000 km it would mean I have to do 175,000 km to break even on the money alone.

Now lets factor in the cleaning - how exactly will you ensure the Stainless filter is properly cleaned?
Whether you use a machine or cleaning medium there is a further cost involved, then we have to consider the time it takes.

If the Stainless filter was more reasonably priced, then maybe I would consider it, but the price is high basically because they know you only buy them once.

No thanks, I will stick with the 'take out old, put in new....put old in new box and dispose' as the Oil and Filter change on a TR650 takes long enough anyway.

An additional thought...If stainless filters are so good, then why are they not OEM fit on modern good quality bikes?

Consider the PC Racing filter at $19 from a vendor in Texas. I bought 2 (#116 for the 310). I am never without a fresh one same as air filters (2 Twin Air I clean and oil).

Cleaning is like this... Small half height Peanut butter jar is what I store my spare in. That jar stows inside a old yogurt tub in my tool box. When I change the filter, I place it in the glass jar and spray some brake cleaner into the center orifice blowing debris outward. I then put a small rubber stopper in the hole and spray the outside and the pleats. Slosh it around the small jar. See the sediiment, then pull the filter out and put it into the yogurt tub filled with hot water and Dawn. Slosh around and drain, then rinse and blow dry or a shot of MAF cleaner to remove any moisture. Stow back in glass jar after it (the jar) is cleaned. Costs $3 for an entire can of brake cleaner and MAF stuff is lying around. Dawn always in the house.

Not prohibitive if you go the route of the PC filter. Scotts and K&P I believe are one and the same, expensive and I too hesitated. The PC are less expensive. Doing oil and filter at 300 miles means in 3k miles that's 10 changes cost is a wash compared the standard replacements. My bike is going a whole lot more miles so it is a cost savings and a convenience. Only you can decide what works for you but this is what I have done.

Just checked the vendor and current price is $23 for the filter... ZipTy carries them at the same price but as a sponsor offers a discount to us at CH.
