Cappellini Products for CB77...

Yes on the good oil (Rotella 15w40), yes to regular oil changes (every 1000 miles), but I don't have a magnetic oil plug. Any idea where I could get one that's the proper fit?

I obtained some a few years ago from Sirius Consolidated. Looks like their current part number is 027998 for the plug, and SCI8486 for the washer. Regards, Chase

Hi,

A magnetic oil plug is one of the most interesting aftermarket parts you can buy for the engine. Steel particles are hard, being particles of gearbox teeth and hardened (cam)shafts (hardness between 50 and 65 Rockwell) and must be filtered out, before doing more damage.

Another very hard material is chrome (from the bearings) which is not magnetic and very small, oil changes and cleaning the oil filter are the only remedies.

Hello everyone,

Fascinating thread. Interesting data on the design of the spinner filter, Jensen - I believe you provided that info before, and I remember it.

My Superhawk has almost 30,000 miles on it, uses NO oil, runs fantastic, and has never been rebuilt. Still original rings, valves, etc. Of course, I haven't raced it, but it's had it share of fairly long highway speed trips, as well as mountain driving (long climbs in 2nd gear at 7,000 rpm's). I clean the spinner filter about once a year and it usually isn't dirty enough to justify the effort!

So this is my question - is the filtration / pump system in the 305 motor deficient? Since it is a roller bearing design, there isn't a need for high pressure. I'd like to hear from those who've raced the bike to know if there have been problems from oil starvation. From my experience I wouldn't spend the $400 to $500 on modifying the oil pump / filter.

Re: magnet. I went to the local electronics repair shop and asked for a broken piece of speaker magnet. That's on the bottom of my drain plug right now! Works great.

Again, great post.

Hi,

I prefer large diametrically magnetized countersunk pot neodymium magnets, very strong and temperature resistant.

Jensen, do you have a source for a good magnetic drain bolt for the SuperHawk?

[jensey]

Hi,

After looking for a quality magnetic drain bolt a while, I decided to made them myself.
The reason for this is that the magnets used on the plugs I've seen are not very stong.
I use neodymium because these magnets are very strong and heat resistant so it won't loose it's magnetic power when getting hot,
