I really LIKE that idea. We have an electronic surplus store locally that sells those little button magnets. Those tiny shavings that naturaly happen become worse when recycled through the engine again. Sounds like this would reduce some of the wear on internal parts. . .
Cheap Engine Protection
Here is a thing I use on all my vehicles: get a rare earth (neodynium) magnet that fits inside the round recess in the Majesty's oil drain bolt head. These magnets are amazingly strong. Will cost about $2. Since this bolt is threaded into aluminum and at the bottom of the crankcase this will attract a lot of the steel debris that gets in your oil - you can wipe it off with each oil change. Think all that debris gets filtered out by your oil filter before the oil gets to your engine? There's all kinds of ways oil bypasses the filter. In a overhead cam cycle engine one of the main ones is the cam chain drive. The cam chain is driven off the crankshaft - which picks up LOTS of oil from the wet sump - called windage. The cam drive chain takes this unfiltered oil directly up to the top end of your engine.

Thanks. I came up with the idea of using the rare earth magnets myself.
The news about the cam chain I got from MotoMan

That site is really worth looking at. As he puts it, he examines a lot of things we have "known" forever about internal combustion engines and debunks them - he calls it thinking outside the box. His speciality is building winning racing motorcycle engines and he has a lot of wins to his credit. Read why the Majesty's muffler is set at the wrong angle........
His most radical idea is that almost every cycle engine will make more horespower with 30% SMALLER intake ports.
After I posted I thought I should have suggested putting a magnet on the final drive gear oil drain bolt too. Going to do that today. After all, that oil is 100% unfiltered.
Another really interesting site has the most detailed info on motor oil I have ever read: Read why Mobil 1 and Castrol Syntec are not REAL synthetic oils and how they sued to maintain their false claims.
The site is:

I've used rare earth magnets on other cycle and automobile oil drain bolts. I also put them on spin-on type oil filters (just take them off the old filter and put them on the new when you change the filter) - you can now buy a plastic coated magnet for spin on oil filters for $60 - but why should you pay $60 when a $2 magnet will do the same thing?
Also have replaced the regular magnets in car auto transmission sump pans with rare earth magnets. They are so cheap and so much stronger than regular magnets I don't know why the factories don't put them in auto transmissions now.

I bought one of the magnets that you put on the bottom of your bike to change red lights because scooters do not have enough metal to make them change. It does work by the way. but they sent me one of those little magnets you are talking about. They said to put it at the bottom of oil filter.
I didn't seem to understand how on the majesty. Now you say it goes in the hole of a bolt. Please explain as I am not very good at this.
have changed oil and antifreeze in cars and spark plugs but beyond that I am lost.
Does it go in the hole where the drain bolt screws back in or does it go in one of the bolt holes that hook on the oil filter.
If I seem a little dumb, I am. Just want to do it right because I already have the little magnet (it is circular like a bearing).
thanks

Excellent idea! I know many manual transaxles for cars have magnets in the drain bolt, I'll be sure to do this on mine when I get it (next Friday hopefully :toothy7: )
pampb - when they say "put the magnet on the oil filter" they mean if your vehicle has an external canister type oil filter like most cars - I have magnets on the oil filters of both our cars.
You cannot put a magnet on the oil filter of the Majesty since it is an internal cartridegless type.
Put the magnet on the oil drain bolt (not the bolts that hold the oil filter in the crankcase). I also suggest putting one on the rear main drive oil drain bolt.
Hope this helps!

Thanks. I was just not sure because I thought it might fall off and roll around the oil pan. Guess if its that strong of a magnet it won't.
Next oil change will do.

Sorry - I didn't explain clearly. You put the magnets on the heads of the bolts - on the outside, not on the tip inside the crankcase. Both the oil drain bolt and final drive oil drain bolts are steel threaded into aluminum housings. Putting a bolt on the head will magnetize the whole bolt and if there are any pieces of steel that come near the tip they should stick to it.
This looks like a better, although more expensive way to go:

That is a rare earth (neodynium) magnet in a machined recess in the tip of an oil drain plug. It probably is more effectove but for the cost of a neodynium magnet - $2 max, and an oil drain plug - again $2 max, $22 plus shipping and handling is a lot to charge.
There is also a company making a flexible sleeve with neodynium magnets that fits around a cartridge type oil filter - they are charging $50!
Whichever way you go I do suggest magnetizing your drain plugs - I have found some scary amounts of metal on a few. I think this is especially important in areas like the final drive of the Majesty which has no way to filter the oil. That is why they are routinely used in car differentials and manual transmissions. Automobile automatic transmissions have rudimentary filters (metal screens) and also have magnets in the drain pans. For a reasonable cost you can convert your car to having a real cartridge type filter for it's automatic transmission and I have done this:

How can a magnet do much good since 90 % of the running gear is aluminum and magnets do not attract aluminum?
That is a good question. Magnets are useless for aluminum particles. A member recently posted about his piston skirts breaking up, which was really scary, and magnets wouldn't have helped at all.
But a lot of the stuff that actually wears is steel. This includes the gears in the rear main drive, camshafts, shims, buckets, valves, valve seats, piston rings, etc.. Even your oil pump is made of steel and cast iron and wears. In fact, most of the wear surfaces in the engine are made of steel, cast iron, or steel coated with babbit material, not aluminum.
This wouldn't be a problem if all your oil went through the oil filter but there are two main ways unfiltered oil gets into your engine:
- when you hit a bump the oil in the crankcase sloshes all around, contaminating your low end (crankshaft, connecting rods, pistons) with unfiltered oil.
- the timing chain acts as an "escalator" to bring unfiltered oil to your
top end.
- from my experience those large chunks of steel on the magnetic drain plug add are rare - I think they are to scare you into buying the product, but you WILL get a fine steel "dust" on a magnetic drain plug even with high quality oil and a good filter. Will it make your engine last forever? No. But it's cheap - the magnets run about $2 or less each - and I think it does help.
If you ever take the sump pan off a car's automatic transmission you will find a magnet(s) with a LOT of steel dust - that's cause those screen filters don't filter that stuff at all - which is why I don't like them on vehicles like the Honda Reflex.

Where do you get these magnets I would like to get some but when I went to some of the local stores I was looked at like I was off my rocker when I asked for a rare earth button magnet. My majesty has not made it to the 600 mile service yet so I'd like to find one asap.
If I have to I'll ride over your way and get them from your sources. Avon Park is not all that far away.
Thanks

Just do an ebay search for neodymium magnets - get the 1/4" diameter ones - they fit perfectly in the bolt heads of the Majesty's oil and final drive drain bolts.
For cars I use the 1" diameter ones - I put one on the outside of the oil filter and one inside the automatic transmission pan.
Hope this helps - if not, send me a message.

I'd say 3/8" should be somewhat better cause I got 1/4" and they are kind a small and do not fill the cavity on the bolt head. You can find 3/8" x 1/8" or 3/8" x 1/16" grade N48 very strong magnets. They may be more expensive but if the idea of magnets works then as stronger you get as more efficient they will be.Ishabaka said:Just do an ebay search for neodymium magnets - get the 1/4" diameter ones - they fit perfectly in the bolt heads of the Majesty's oil and final drive drain bolts.
