Project 2005 Gs/pd Lets Build A Bike!!
 
So the madness has a firm hold on me and I find myself the new owner of a 95 GS/PD classic. She is almost stock, aside from a corbin solo and some brandx fog lights, and as such,I see this as a white canvas ready to be painted.
I would welcome any 'brush strokes' to this project that would enhance; drivability(performance and handling), long distance comfort (Mexico from SoCal)), and reliability(70k+mls presently).
With the vast number of third party improvements available today, and the many years these 'mods' have been field tested, I am keen to hear your findings regarding your choice of gear (Ie. WP or Fox or Ohlins or Penske or etc...). I also realize that all things in life are a compromise so if you could give your reasonings for your particular choices, these would be invaluable.
I look forward to hearing your $0.02 and hope that this might turn into a project that will of intertest to others in the future. I will not be receiving the bike for a couple of weeks but as soon as she arrives I will proudly post some mugshots. She is Black and Chrome, ay chihuahua!

I don't know shit and
 
I've never owned an airhead so I'm speaking from no experience, but I'm in the market for a PD myself so this is what I'd do.

I'd upgrade the suspension: Ohlins in the rear and Progressive fork springs.
I'd upgrade the front brake: Harrison 6 pot and associated items.
I'd upgrade the electrics: Omega system or whatever is best. :dunno
I'd upgrade the shaft: Rebuildable with zirks.
I'd upgrade the lighting. maybe HID :dunno
I'd upgrade to Jesse luggage for the long haul.
Then I'd ride the bike to figure out the minor stuff.
You asked for $0.02 and that's mine. :nod

GuinnesS 05-03-2004 03:18 PM

I am $0.02 the richer!

Anything's better than stock. PS springs help up front, but only some--certainly, on that lardass PD you'll need'em.

Unless you race or weigh 300 lbs, the stock Brembo is fine, especially off pavement. Skinny front tire limits braking more than the brake. The master cyl sucks worse than the caliper.

Don't know about Omega. Motorrad Elektrik has rewound rotors that last. More capacity is just gonna uncover the next weakness. Whose idea was it to put a board fulla diodes inside the engine cover?

You really gonna ever grease that? Lots of alternatives. Bruno. Factory.

A 55/100w H4 will work. Far better than stock, though that's faint praise. HID certainly seems to be the latest/greatest. Especially for the lame-ass airhead charging system.

Never used Jesses. Would love to, I'm sure. I've met the man, seemed a good fella, the kind you'd like to have make yer luggage.

Tons of little things to do, to make maintenance convenient, to fix little vulnerabilities. But mostly, stock is best. Stock is always best, except when it's not. Ya really can't change a GS much in big ways; just lots of little stuff. After ten years, I realized the stuff that really bugged me about were big things, things that meant building a custom bike to change. So I sold it.

Oh, and it took reading Ricky's essays here to realize that the bars SUCK. Wait, the pegs suck, too, get metal ones. Big diff.

Have fun.

Nice bike you got there - after my ' 92 PD I like the ' 95 classics the best. Here's my $.02:

I think the best upgrade for these bikes is suspension - progressive springs and 10wt oil in front, Ohlins or Works shock in back - you'll have a new ride you won't believe. Stock suspension on them is like a ' 63 Cadillac (with '63 springs). I've got ~ 18K on a Works rear and it's great, covers the whole range from 2-up camp-touring off the slab to solo commuting, with adjustment range to spare on each end. Cheaper and easier to find than an Ohlin last time I checked (though Ohlins distribution has improved alot since, mostly targetting the oilhead market though). Given that you're in Hawaii, you may or may not need the extra juice of an Omega 400W alternator to run heated clothing, lights and such, but it is a well-built setup and easy to install; at least don't discount it based on Stephen's concerns, they come with their own much beefier diode board, and heavier copies of every other connecting wire in there as well. If you stay stock, buy a spare rotor and the tool to replace it right away, along with the 'classic boxer charging' book, all from Motorad Elektrik, and carry them with you if you travel far - Rick Jones at Motorad is your friend, get to know him, he is a walking encyclopedia on the electrics for these bikes and sells good stuff. No matter what, DO get some kind of on-board voltmeter - otherwise a dead battery is something you will be sure to discover when it's most inconvenient. Stock lighting is weak - get the brighter bulb, and carry the stock as a spare. Hang a pair of your favorite aux lights on it, whatever suits your style and locale. I've got PIAA 1200's cuz they're low draw (got 'em long before the Omega) and have a medium-range beam that can be aimed low to stay on all the time, augmenting the pathetic low-beam in traffic without offending anyone; yellow is easier on drivers' eyes at night and more conspicuous in daytime too.
This bike's two real achilles heels are the aforementioned alternator rotor, and the drive shaft - unless you're prepping for a long trip elsewhere, Hawaii is small enough you'll get home if it starts to go - just spin your back wheel in neutral once a week or so and see if it's smooth. Any notchiness is a bad sign, and if you leave it go all the way you may hurt your tranny bearing too. Mine went bad at exactly the median age of 35K. Don't replace it with another stock shaft, there are a number of better options available - Oak of Airheads fame is developing some CV-joint shafts, had pics in last month's Airmail - they may be available for sale by the time you need one. I've got a rebuilt from Eric Demant in Germany, has grease zerks on it. I'm about to open 'er up to do the splines (every other year or so), and will grease the joints at the same time. He says it oughta go 100K or so; that'll take me awhile.

Strip the 'pure air system' off the motor (those ugly tubes that come off the motor and go into the air box) - they don't do much, just cause vacuum leaks that are hard to trace, look bad dangling down there, make it harder to clean if you're into that, and cause the valves to run hotter than they should. See either the Airheads or IBMWR websites for a good writeup and a complete parts list on how to do this.

What else? A front brake upgrade is the last thing I plan to do on my bike; I tried to get a Harrison for mine last fall and discovered the american distributor, CBT imports, bailed on Harrison last year; e-mailed Harrison direct and didn't get a reply so blew the cash on the Omega, then they replied months later and offered to ship me one, but it was very pricey alone plus $55 shipping via their 'only option', so wait for a good exchange rate if you wanna go that route. I'm now looking into fitting a 4-pot caliper from a newer BMW, or even from some jap bikes; you will need to build an adapter bracket, but it's probably half the price of a Harrison. Larger rotors are reported to be good; but it means scavenging the core from your stock rotor to mount it, and if it's bent (and the guy who sells these MAP rotors stopped exchanging cuz most are) you'll need to buy a new stock rotor (~$200 min.), scrap the disk, AND pay the ~$300 or so for the bigger roter (which comes with a machined bracket for your stock caliper). I'm still running stock, and have long believe what Stephen said here, that the limiting factor is the small front tire - but having felt the brakes on Jabba's 03 GSA, I now know what I'm missing. Will probably at least get a braided hose soon. As for rear brake, not alot of options - I just switched back to stock shoes in the rear drum, had EBC's in there for 2 years and they sucked. Stock is much stronger.

A set of Ricky bars would be the icing on the cake.

Enjoy your project, and post pics!! Over in the ' ride reports' forum there is a thread right now called 'what shape is your PD in' - so let's see yours!

Gringo,
Great stuff! It seems most people recommend suspension and front brakes. When you say the stock shocks are like a '63 Cadillac, does this mean it has great highway comfort? Can't say I' ve ever had the pleasure of riding in a 60's Cadillac.
This bike will be kept on the mainland in central California and has yet to make its way there from Daytona, so I am very interested in all matters relating to distance riding with this bike.
Tanksamillun!

I currently own a '92 PD that I ride/rode off road quite a bit.
I weigh 200 lbs and have done the following mods:
-Rear Ohlins from PPS Racing in SoCal dialed for rider weigh and riding style
-Front Suspension: Race Tech cartridge emulator with stock springs: MUCH better than progressives alone. Increased fork oil weight to 10 or 15. Huge difference off road and under severe/hard braking.
-Front brake: Harrison 6-pot with MAP 300mm rotor, Stainless line and Galfer Green pads. Stops unlike any other airhead I've ridden. Any good 4 pot brake would be better than stock.
-Rear Brake: Wudo inverted actuator lever...keeps it away from the rocks
-Lowered custom footpegs
-Transmission:Wudo taller 5th gear with output shaft cir-clip
-Piaa 40 drvin lights-Use sparingly
-LED Tailight bulb- Always cary a spare on a airhead or get an LED.
-Bars/Ergo:Touratech 25mm bar risers
-Pair fo extra wheels with MAP rotor and Pirelli MT-21 Knobby tires for off-road

What I'd like to do from this point/wish list

-Omega 400 Watt charging system: They've been out for some time now and have proven their reliability over the stock system
-Ricky Bars and risers
-Touratech Road book/map holder with additional Rally tach, speedo and odometers.
-Chromoly Subframe- take a few more lbs off.

That's my $.02 so now you've got what $.04?
Cheers,
Jorge

My .02
 
I'm a 7 year Oilhead owner with lots of miles. Just picked up a 93 PD with 68K which is only my 2nd airhead. Here's my .02:

The first things I did to my bike were:
- New tires (Avon Gripsters)
- New battery (mine had the original battery from 11/92 in there!)
- New driveshaft (#2 achilles heal)
- Upgrade electrics to Omeagea 400W kit.
- Replaced my starter with a new Valeo. I know, Bosch is preffered but I got a new Valeo for $160.

There, now my bike is rid of all of the things that NORMALLY leave airhead owners on the side of the road.

- While doing the other upgrades I also have my splines lubed, checked the clutch for wear (almost brand new), replaced the trannie and rear drive input seals, the neutral switch (slight leak) and the rear drive paralever bearings (shot).

My bike's engine is quieter than any oilhead I've ridden or owned. I'm happy with the power and the breaking.

As for upgrading the brakes, I was planning on this but will not. Why? I only ride solo with this bike. It's only got a 90/90 21" out front. I think more brakes would just reveal that the tire is the next limiting factor.

The PO of my bike replaced the shock with a Hagon unit from the UK. It's ok, but I would have done Ohlins or Fox (if they make one). The PO also replaced the rings, steering head bearings, etc.. so the bike is solid.

I plan on riding it about 10K per year until the wheels fall off.

This winter I will have the carbs completely rebuilt ($300 parts and labor for the full monty), and maybe look into freshening the rear drive or trannie.

Tom

Good point, forgot this earlier but the starter was the 3rd ' big thing' to go on my bike, at ~42K last summer. I replaced it with a rebuilt Bosch, now wish it would've waited another 6 months to die so I could get one of those modified Toyota starters Rick at Motorad Elektrik has started selling. I had two Toyota trucks and put a combined 250,000 miles on 'em and the starters never gave me any trouble; they're substantially lighter and use alot less juice than the Bosch - at times it feels like my battery (an otherwise strong 3-yr old Westco sealed) is straining to kick this Bosch over, something it never did with the original Valeo - it may just be the battery is gettin' old, but the Bosch IS rated to draw alot more amps than either Valeos or Toyotas. Also if you're ever thinking of doing a global tour or something, it seems Toyota light trucks are popular just about everywhere in the world except maybe Russia and China; I'm betting it'd be easy to find parts or replacement cores.

Rubbercow, I got front-brake envy! The best of all worlds, larger rotor AND Harrison 6-pot. Not that I'd ever want to, but under the right conditions I bet you can do stoppies! Been thinking about that cartridge emulator for awhile too, might've been you here telling me about that last year - I looked a bit further into it and then forgot about it, may be time to reopen that search...

Any more info on these Toyota starters? I looked at the Motorad page and didn't see anything about them.

Gringo 05-11-2004 11:58 AM

I don't recall the price but am quite sure they are cheaper than a Bosch. They had an ad in the latest 'Airmail' of Airheads, and I'd seen 'em a month or so ago in the MOA rag as well. Call or email Rick - from the ads it sounded like he's selling 'em and has a bunch ready to ship.

If you get one, let us know how it is!

Cpt. Ron 05-19-2004 09:21 PM

I've had mine for a couple of years now. First thing to do is verify the maintenance items are tip-top. These include all the electrical connectors are clean and tight. Battery top notch. Alternator brushes proper length. Clutch spline lube (which leads to the clutch inspection, oil seals, swingarm bearings, paralever bearings), fluid change (no solid metal flakes on the magnetic plugs for the rear end or tranny), good carb cleaning (remvoing float bowls and jets, maybe replacing needle and needle jet due to wear).

Upgrades? Suspension and brakes. I have a Fox rear shock, and the Race Tech valve in the front (along with Works Performance springs). The Harrison caliper I have is nice, but do a steel braided line first, and then think about a caliper and/or rotor swap. I've also done some little things, like changed the charging circuit a little bit to minimize losses, added a voltmeter and ammeter to monitor the crappy system. Ricky bars! Need I say more. I removed the stock speedo and use a Trailtech unit. THis allows me to remove the speedo drive cable from the tranny (and another spot for water to enter). I relocated the negative cable to the right/lower tranny/engine mounting bolt (no broken rear tranny cover for me!). I raised the seat. I've installed oilhead pegs for better wet traction (though I still need to lower them to the stock USA GS height). My bike came with Touratech bags, but I'd probably buy Ortilib dry bags instead if I had to.

Christ, the list goes on. I'll think of more tomorrow.
