Sportsterpedia Progress

[Hippysmack]

I don't remember everything I've added lately so I thought I'd update now what I do remember.

I've gotten into a mod frame of mind and I created a few pages for them.

These are still of course works in progress;

REF-Electrical System
Gauge Mods / Relocating for speedometers and tachs.

Headlight - Tail Light Mods / Relocating - I combined the two so far but may have to split them later into two headings.

Turn Signal Mods / Relocating

REF-Body Parts - Accessories
Aftermarket Handlebars, Risers and Mods
Offset Riser Blocks Added tobiism's riser block mod

REF-Shop Notes and Tips:
Twisting Metal Fabricating twists.

Trying to Get a Mirror Finish on Stainless Steel Added my attempt at a mirror polish on stainless.

Polishing Aluminum and Stainless Steel I expanded this to include both aluminum and stainless steel since the process is the same.
Still working on it.

Tool Bags I also started a page for tool bags. Currently I have added Johnny Wolf's swingarm mount thread here.

I've added some pics and info to the "4 speed to 5 speed oil pump conversion" article.
5 Speed Oil Pump on 4 Speed Models (Conversion for 86-90 Evo engines)

That came from the current XLF thread (Oil Pump Upgrade '86-'90)
http://xlforum.net/forums/showthread.php?t=2071753


This article derived a lot of good information on 77-85 oil pumps.

Thank you DirtyCory!

I combined pics and reference data from that thread into subdocs in the IH oil pump section:

This is a chronological order of the upgrades to this oil pump.
The parts catalogs for 79-85 are hard to follow when it comes to nailing down parts that were installed per year.
The gerotor change in L83 is explained hopefully a lot better.
Still working on which oil pump housings belong to which gerotors:
77-85 Oil Pump Parts Lists and Upgrades

These are individual pics and info on the oil pump parts:
77-85 Oil Pump - Individual Parts and Pics

This page has app. dims for the parts:
77-85 Oil Pump and Parts (approximate) Dims

I created a page in the REF-Oil section on oil filters.
Understanding Oil Filters

It was a primer for me on understanding how it works.
I thought maybe it'd be interesting to someone else.
I'm sure it's not complete but hopefully a good primer at least.
As always, input is invited.

Thank you guys very much. You are leaving quite a legacy that should benefit others for a long time. Did I say thank you?

Looks great!

There is an ISO standard test for filters-
https://www.machinerylubrication.com...er-beta-ratios

Most filter marketing doesn't list Beta Ratios but some have started to show them (WIX). Usually the marketing will say"captures 98% of particles" but doesn't list the particle size Many will list a foot note with something like at 20 microns testing a specific part number (not usually the HD compatible filter)

Another link for reading about oil filters - "How to Choose the Right Oil Filter"
https://www.machinerylubrication.com...ose-oil-filter

"People often worry that if they switch from a 40-micron filter to a 10-micron filter for the sake of better contamination control and prolonged engine life that the oil filter will plug more readily, leading to restricted oil supply to the engine. We've already talked about the fact that these filters have internal bypass, so starvation is not a practical reality.

When you think about it, the positive-displacement pumps used in automobiles deliver flow to the oil filter and then on to the engine at a rate proportional to the engine's speed. For instance, if the engine pumps 1 gallon per minute (gpm) at 3,000 rpm, at 6,000 rpm it will deliver 2 gpm and just 0.5 gpm at 1,500 rpm. In general, the pump will deliver the flow (assuming no inlet restriction or pump wear) regardless of the pressure restriction. As flow rate increases, so will pressure. A good rule of thumb is 10 psi increase for every 1,000 rpm."

Keep up the great work!

Thank you for the links.

I've started with the list you provided for comparable filters and got a bit confused on the data.
Then, I did some research and found what was confusing me.
There is a lot of marketing (just like engine oil) designed as a smoke screen.
"Mine is better than yours" again.
I'd just soon know the truth.
Oil filter propaganda seems to rival or may even be worse than that of oil brands.

edit: I also added rocketmangb's oil filter comparison in the REF-Oil section.
I added captions and labeled a couple pictures:
