The rain part is really something.... makes me don't wanna use my bike. Its been sitting in the carpark for a few weeks now.

 

 

same goes to me already a week been coverd lucky i had sprare bike to go to work lol

[maxxmadness]

about riding in the rain..if i rode my fazer and harley to work and it rain, i most probably will park it at work and take a bus home..but if i were to ride my GS and it rain, i most probably will ride it home in the rain..it's a dual purpose bike and it meant to be use rugged

[tofuman]

yeap i agree with tat as Bmw bike is not for speeding of thriling as it was a safe fuel comsumption bike i presume. And that was been told to me recently lol. if want speed u could try R1000 or k1300

 

That's a good one.

[tofuman]

Harlow... Got a qns to ask...

If I lost my keys,

am I able to,

replica key from any key maker?

 

Don't think you can duplicate the keys, it's coded. You can go to the part store with prove of your ownership and chasis (or engine number - sorry you need to confirm on this) and order from them. Alternatively you can talk to Kris he should be able to order for you. Price is $70. Hope it helps.

It depend on individual riding habit. For me i use to travel on (60%highway - 40%city)

Yamaha Fazer 600 > 18km/L

BMW f650 GS Twin > 25km/L

both speed not more the 120kph.

[tofuman]

I contacted him through http://www.pml.com.sg. You may want to let him know your requirement what you want. He can keep a look out for you.

 

Good that PML sells used bikes now. Years ago when they were at Kampong Arang this was not even heard of.

Hello everyone!

 

It's been two years and a lot of hard work, but I've finally finished rebuilding my BMW R1100GS. She's a 17 year old, 1994 model; the first production run of bikes that had no ABS and a completely different engine management system for running without a catalytic converter/oxygen sensor. I bought the bike on a tight budget some years ago from a nice guy I met on the SBF Forum and she's been with me ever since. She was a little ratty when I first picked her up; here's a list of things that were defective:

 

1. Worn Paralever bearings
   
2. Leaking final drive
   
3. Defective ignition trigger
   
4. Broken sidestand
   
5. Warped centrestand
   
6. Damaged steering lockstops
   
7. Warped/worn brake rotors
   
8. Rusting frame
   
9. Bent handlebars
   
10. Damaged wiring harness
    
11. Horn that wouldn't work! Very important...
    
12. Leaky oil sump and cylinders
    
13. Leaking brake master cylinders
    
14. and lots of other stuff I can't remember...
    
15. 
    

 

Eventually I got fed-up of fixing things one at a time and stripped the bike down to pieces:

 

 

Believe it or not, there's an entire GS in those boxes; the only bits you can't see are the frame, bottom end of the engine, subframe, wheels and tyres. Unfortunately I didn't photograph a lot of the parts just after the bike was torn down, but here are a few pictures so you can see the extent of the work.

 

 

This is a shot of one of the throttle bodies. The throttle bodies were so badly worn that the bike would not idle properly and suffered from poor fuel consumption. I tore them down and rebuilt them with new shafts and seals. Parts were obtained from http://www.bingcarburetor.com/ except for the throttle body bushings which were machined by hand. I later found out that you can buy the same bushings from almost any bearing supplier here in Singapore. I chose SLS Bearings: http://www.slsbearing.com.sg/eng/index.html and realised that the commercial bushings are far better than what you can machine yourself; even better than the OEM units that Bing uses in their throttle bodies!

 

 

You may not be able to see it in the picture, but the throttle shaft is very worn. This made it almost impossible to synchronise the two throttle bodies. The shaft would also jam occasionally making it hard to open the throttle.

 

The Hall sensor was also damaged. Fed-up with poor service, high parts prices and continually failing ignition sensors, I tore down the Hall sensor assembly to troubleshoot it. This is what I found:

 

 

You can see that the wiring was badly frayed and corroded. This was caused by water ingress in the wiring harness. I cut and replaced all the defective wiring with some good quality wire (shop around in Sim Lim) and heat-shrinked the harness with heat-resistant shrink tubing. This should keep it running for a while more.

 

The motorcycle main wiring harness was also damaged. I was getting increasingly frustrated with the amount of LOUSY workmanship I had to rectify; the poor motorcycle had been slaughtered by some bike shop, wires were chopped up here and there, fuses were replaced by bits of wire, relays were the incorrect type... so I tore the electrics down and went through the harness bit by bit. This took me about a month, working one or two hours a couple of days a week. Here's a picture of the mess I had to repair:

 

 

Once that was sorted, I turned my attention to the final drive. It was leaking badly, bearings were shot... the shaft had failed at some point in time as well. I stripped the final drive down for repair; I don't have pics of my final drive rebuild, but here are some pictures of a rebuild I did for a friend's R1150GS. The driveline architecture is the same on the 1100 and 1150 with minor differences in suspension mounting arrangements:

 

 

You can see clearly in this picture the missing rear end of the motorcycle.

 

I shall continue with another post in a bit...

Moving along...

 

The original suspension units were worn out, so I replaced the stock shocks with Wilbers suspension units. Here's a picture of the front shock, it is a rebound-adjustable unit:

 

 

My opinion? Not a waste of money but here's some food for thought; the Wilbers front shock CANNOT HAVE THE PRELOAD ADJUSTED WHILST IT IS ON THE BIKE! This is completely different from that of the stock Showa units on the GS, which can be adjusted for preload whilst the shock is in place. My advice? Keep the stock front unit, or replace it with an aftermarket part that can be adjusted WITHOUT removing the shock from the motorcycle.

 

On to the fun bits...

 

Here's my bike about 1/3 through the rebuild:

 

 

And the other side:

 

 

By this time, I had finished blasting and powdercoating the frame, final drive, front suspension and Telelever fork, front forks and little bits and pieces. The rest of the plastic bits had all been repainted as well. Again, I did not document that part of the rebuild, but it took me a couple of months to get everything blasted, powdercoated and painted. All blasting was plastic bead blasting, non-destructive but good enough to remove paint, dirt, rust and corrosion.

 

Powdercoating and polishing was done by David Kong of Weng Wah Polishing Work: http://www.thegreenbook.com/companies/weng-wah-polishing-work/

 

Here, you can see the LeoVince Evo II aluminum muffler that I fitted. Nice sounds (apart from the annoying high pitched twittering at idle) and great looks at awesome prices! Polishing was done on a large buffing wheel. I did the headers myself, but the end can was polished at Weng Wah.

 

 

The exhaust was purchased from Mr. Chan at MTeknik: http://m-technik.com.sg/ and fitted by myself.

 

Removing the stock exhaust leaves a large gap between the centrestand that can cause it to warp. I scratched my head for a bit and thought up something to support the centrestand, whilst acting as a brace for the sidestand mounting plate. The part was machined to my specifications by Machinist Mr. Henry Yee, owner of Hup Yick Engineering: http://www.thegreenbook.com/companies/hup-yick-engineering-pte-ltd/

 

Due to my poor health and work commitments, my dear motorcycle sat idle for a couple more months. Finally, I completed all the running gear and had the chassis rolling. By this time, I was quite unwell and so I looked around for a workshop that could help me finish my project. After a few interviews and an inspection of their workshop, I contracted BHH Motorcycles to undertake the remaining assembly work:

 

http://www.banhockhin.com.sg/homepage.html

 

I crated the remaining spares (boxes, tank and various bits and pieces) and sent them off to Ban Hock Hin. Over the period of a month or so, I sat down with them and drafted various designs for a rear box mounting rack, customised horns brackets, driving light brackets, modified (lowered) footpegs, custom-built wire harness and central electrical distribution box. Once the planning and organisation was complete, they started work on the bike. From time to time I would drop by to supervise the work and review modifications and some of the custom fabrication work.

 

Here is an example of the custom built light bar with HID driving lights that Ban Hock Hin fabricated:

 

 

The light housings are modified YungLi YL2033 units that were fitted with HID bulbs instead of the standard Halogen H3 units. The lamps and HID kit were obtained locally from various car forums; a little searching found that the parts could be gotten cheaper from eBay!

 

The original lamps are pictured below:

 

 

I worked with BHH to modify the lamp housing and fit the HID lights. The lights are wired with a high-power relay and controlled by my turn-signal cancel button through an Autoswitch AS5NB unit. The Autoswitch was relocated to the BMW fusebox and connected to an auxiliary electrical fusebox that I created.

 

Finally, she's back on the road!!! What a joy to ride this beautiful machine!

 

There are still some minor hiccups with the fuelling that need to be sorted; plans are in progress to fit a Techlusion FI controller that will allow me to adjust the Motronic unit better. At the moment I am using the CO pot from the 1994 model GS that allows for minor manual adjustment to the low-end and idle fuel supply.

 

I'll post some pictures of the completed bike next...

All things you've worked hard for usually end on a good note; my GS restoration project was no exception!

 

Here are some pictures of the completed bike:

 

 

 

 

 

I hope this post has helped those of you who are keen on working on your own BMW motorcycles. It's not difficult. It took me a long time and a lot of effort to wander around and look for suppliers, parts, accessories and find people who could help me with my project, but the work paid off.

 

I have owned MANY motorcycles in the past, but the GS is, without a doubt, one of my all-time favourites!

 

Cheers;

MJ.

I forgot to include a picture of the brace that I designed...

 

 

It is made of stainless steel to resist corrosion but is overkill for the application. Stainless steel is also hard to machine and is a rather heavy material.

 

A better solution that I have devised is to machine the same part from aluminum rod stock, round bar approximately 15mm in diameter. The bar can then be parted to the correct length on a lathe. Mill spanner flats for a 13mm spanner midway along bar, radius slot with a ball-nose end mill to reduce the chance of the bar cracking along the spanner flat. The spanner flats are required for you to have something to hold the bar in position whilst tightening or (more importantly!) loosening the fasteners.

 

Either end of bar: Drill hole, depth approx. 10mm. Tap for M10 X 1.25 Helicoil insert (this is necessary as aluminum is weak and threads machined in aluminum parts usually give way after a while). Install Helicoil.

 

Anodise (preferred) or powdercoat to match the centrestand colour.

 

Fasten with countersunk Allen screws, stainless steel.

 

I cannot remember the exact dimensions of the part, but anyone can figure out how it is done; not too difficult.

[Limsteel]

Sweet bro, why didn't rope me in on this. I would gladly rendor some help. Seems like bike restoration is in your blood. PM me for tea. You still putting up at changi?

Excellent details on the restoration work, did you also document the various costs at various places?
