For the new members:
The idea came years ago from Fred Strammer. He found an easy way to lubricate the swing arm bushings without the need to take the swingarm off. Loosen the swing arm bolts, and pull them out. Now drill a hole of about 0.05" (not ALL the way) thru the center of the swing arm bolt(s). Drill two more 0.05" holes from the top of the bolts (where the contact patch of the bushings is located) and hit the center hole. Now you can grease the bushings with a grease gun (pointed head) thru the "hex-hole" - (sorry, don't know the right word for it) of the allen- swing arm bolt.

What I found out is - it works, but most of the time I had more grease under my bike than inside the bushings. Therefore I machined a grease cap, which I install once a year with 4 grub screws on both bolts to lubricate the bushings. In the center of this cap is grease nippel. Now I can PRESSURE the grease into the bushings without any grease on the floor! When I'm done, then I install my two polished SS dust caps back, with only one grub screw- unvisible- at the bottom. It works so nice- I thought it might be interesting for some of you...

Here is a pic of the service-grease-cap and the SS dust covers...

Olaf, neato tip dude! Thanks. I will keep this in mind and do so when I grease it! Too cold now though to do it. ug. Frigging winter is setting here in Massachussettes.

Very Cool 8) I remember when you were just a Boss Hoss wannabe. ;) Now your one of the head tech guys here. :D Remember that next time we have a wannabe posting on the board, they may be the next Olaf. 8)

Lamont,
I really appreciate the kind words- many thanks.
Ok - except the "wannabe"- I was a "future-owner" these days..hehehe

But..no, no - I'm by far not one of the head tech guys here. :oops:
Fred Strammer deserves the fame. He was one of a kind. The greasable swing arm bushings were only one of many, many good ideas of him.
He was THE Boss Hoss guru back in 99 of the old BHRA forum. These days I was dreaming every night of owning one of these big, bad V8 bikes, woke up every morning with a wet underwear- and knew it will take at least three years to save enough money for it. But I already began to suck all these good ideas and modifications in my brain. Fred quit riding Boss Hoss bikes a while later for some reason- but his ideas are still working very well.

Loaf,

As always, very classy work.

Tim
Thank you, Tim.
As you know (Andy wrote an email to you) he wants to run
a 285 Sumitomo tire on his 502. You've got the 265 Sumi
on your bike - but do you know how wide usually the wheel
for a 285 Sumi is? He found a machinist who's specialized
in widening motorcycle wheels, and Andy's got to decide the
future width of his (stock) mirage rear wheel now...
He can use his stock wheel because they will make it 18"
with weld-in cone rings :shock:

So a 15x7" wheel can be machined to a 18x10".
Damn - I too begin to have have dark thoughts about a
black Boss Hoss with a 285 Sumi in Bueckeburg....
Maybe an upgrade from 265 to 285 next year? ..hmmm.. :roll:

Loaf,

My rear wheel is 9 3/4" wide. It is perfect for the 265 as they recommend a 9" to 10" rim for this tire, with 9.5" being optimum.

A 285 Sumitomo is recommended to be on a rim of 9.5" to 11" in width, with 10" being the optimum for that tire. So if I can fit a 285 into the fender, it will be the next one going on 8) :lol:

The 265 has a section width of 10.6" & a tread of 9.6" the 285 goes to 11.4" on the section width & 9.9" on tread width.

Try going to www.tirerack.com and search tires by size. Once the tires come up, there is a selection band to the right of thires that shows all of the specs and suggested rim sizes, air pressures, section widths and tread widths.

Have fun.

Tim

Loaf...If you would make me a set an send them...I'd love you forever and name your price,,,Joe
@Joe:
Believe me - I would do it in a heartbeat for you, not even charging
any for them but I changed the company a year ago, and they don't give
me any time to machine something for private use where I work now.
Sometimes I machine private parts at night-after work, but that's
not always possible - maybe twice a month... I've laying parts around
at work which I would like to machine since summer, and still have them
not ready. Imagine- me, as CNC milling machinist bought these small
milled aluminum block-off plates in Oregon... :oops:

@Tim:
Called Andy yesterday and he told me he decided to go to 10". Seems
like a good decision after reading your posting. I'm really curious about
the looks and drivability of this 285 Sumi....
