Hi Guys,
So ive been interested in motorbikes and cars for a long time and have been enjoying the cafe racer scene that seems to be getting more popular recently.
Friends and I often talk talk about bikes we like, don't like etc and that we would like to build a cafe racer.
So I thought why keep talking about it and why not do it, im really not very mechanical so I think it will be good to go outside of my comfort zone and try something new.
Ill probably ask a load of stupid questions but please be patient with me and help me out eh, in return ill try to keep this up-to-date with developments and new ideas Shocked


So the bike is a 1984 BMW K100RS with 27000 miles on the clock. I wanted something a little different that you don't see every day but with a good heritage and something that is pretty reliable. I specifically wanted a 1984 model so that it was made the same year I was BORN.


I found this little great looking machine, its had 3 owners and is in great condition with no rust, corrosion etc. For my first cafe racer I wanted something really clean to start with and im pretty happy with it at the moment.

Iv'e already got my first question for you guys, the bike had some chrome engine protectors which I have removed. The bolts on the engine in the image below are sticking out and don't look very nice but were used to bolt the protector into. Do I need to order new bolts to replace these?

With a few bits taken off the bike, I can start to see the shape taking place. I want to do something with the air intake box, I know the standard one works perfectly but its such a huge part of the bike and I wanted something a little different looks wise. There are a couple of conversions that have done this which I am taking inspiration from.

Those are the shock absorbing rubbers for the crashbars - early K's didn't have them and a slide down the road frequently resulted in the sump being smashed off. A 22mm spanner should get those off - don't forget there's three either side.

I'll take the crashbars off your hands if you want to sell them? PM me, if so.

I am always in a quandary over custom builds. On the one hand I enjoy a creative build that's groundbreaking, inspired, different and as I'm a bit of a Teuton from a previous life, practical, ie, I like front mudguards on bikes - they work and look good to me.

On the other hand, when I was inspired to build my '89 K100 Big Block with K1200RS motor, I purchased nearly all of the parts from wreckers and eBay so as not to have to dismantle a running, rideable piece of Beemer history.

As far as the airbox is concerned, there's heaps of good ideas about, as you can see. My favourite is Scheffers (sp?) from Holland. Just remember that in order to make the bike go (8V K100), you must have the AFM intact. No K&N pods on top of the throttle bodies.

Hi guys,
So been busy over last couple of weekends doing a few various jobs and waiting for parts to arrive.
Ive ordered the BSK 4 into 1 exhaust which ive just slotted on for now & have fitted some Raask Rearsets
Cafe Racer K100RS Build & Support WP_20151018_11_36_29_Pro_zpsndcivmhe
Cafe Racer K100RS Build & Support WP_20151018_11_36_48_Pro_zpsbr0bvm3k
The rearsets were difficult to install as you only get a little picture to work from and no instructions. Ive not yet got the rear brake setup right, its a bit floppy and I dont know how to make the brake light work so ill have to figure that out later. Cafe Racer K100RS Build & Support 610153

My mate came this weekend so I recruited him for a couple of hours to help me out fitting the new headlight. Its got a LED ring around the light as a little nod to the BMW Angel Eyes and I think it suits the bike well. Ill have a play with it later on moving it around, maybe a little lower.

Cafe Racer K100RS Build & Support WP_20151018_14_38_58_Pro_zps9ijiuzio

You may have also noticed the Air Intake, after thinking about various options of how to mount the filter, what make, what size, what will fit etc I found a way to mount the filter & im really happy with the result, I think it looks really good.
It fitted really snugly but I made a supporting bracket that bolts from the engine to the unit. It feels absolutely solid with this in place.
Cafe Racer K100RS Build & Support WP_20151018_16_30_32_Pro_zpsttxumb4k
I also cut down and shaped the front mud guard.
Cafe Racer K100RS Build & Support WP_20151011_13_03_14_Pro_zps1gp58x6f

Im hoping some foam blocks come soon so I can start making the seat, if anyone in the UK knows somewhere I could pick some up from that would be great. Ive refrained from chopping the bike frame so far but ill be looking to make a cut soon. I cant weld either so I need to find a mobile welder, there seem to be a few in London.

Exciting stuff! (o)

A hint for the seat. It's easier to build it up in layers that it is to carve it from one lump of foam  That way you can also use firmer foam at the base for support and softer foam near the surface for comfort. I generally use a combination of 2" and 1" thick foam.

So laminate the shape you want in pieces glued togetherusingcontact cement,
trim it up with an electric carving knife, silicon spray on the blades will help it cut through the foam easier, 
sand it smooth to remove any lumpiness(A wood rasp and very coarse sanding disks(held by hand) can be used to sand/shape the foam), 
then cover the whole thing in 1/4" foam to make it absolutely smooth before covering it.  

If the cover is going to be sewn together from many pieces, now is the time to take a felt fen and a tape measure, draw a centreline and think of where the seams will sit before drawing them on. 

If it sounds like I know what I'm doing that's because I'm a qualified Motor Trimmer. I'm helping in the hope that it won't end up being a timber plank covered in brown "leather" like too many cafe chop jobs.

Here is one of the nicer seat/tail mods we've seen on here from mrc
http://www.k100-forum.com/t9861-k100-custom

If you follow the link to his web page, about half way down you'll see how the seat foam was constructed.
Unfortunately you'll also see what happens when you mix off road tyres with clip-ons

That pod filter setup looks great. Another thing I've wondered is if you could get the battery in there on top of the motor, or would it get too hot?

Thanks, the air pod gave me a wee headache trying to make secure and strong. It doesn't touch the engine apart from a little mounting bracket which I don't anticipate to transfer a lot of heat (but time will tell).
There are people I have seen put the battery in the engine area but I'm not sure if this is suspended or on a tray. I don't think you would want to mount it onto the engine.

Been having  a play with Photoshop again to try and decide on the general shape and flow of the side profile.
What do you think guys, 1, 2, 3 or none of these?
I quite like 1 as the angle from the tank follows the line of the bike. Open to suggestions!
The headlight will be even lower and it will have clip-on's too so the front end will look slightly different.

Option 2. The lower rounded tail piece makes the back end look less "chunky". My opinion only.

Just a general question if I may...how do these air filter pods handle wet weather?

An aside:

Once upon a time a motorcyclist with a broken R100GS had to hitch hike from Glendambo to Adelaide to get him and his dog home. He got a lift with a couple travelling together as a pillion on a Guzzi LeMans Mk 3.  It was fitted with pod air filters.  On the ride south there was a deluge while riding through some muddy road works and a loud 'pop' was heard.  The rider of the bike looked and said "that hasn't happened for a while".  The pod had filled with water, the bike had stopped breathing and a carby along with its pod had backfired off its manifold!

Next garage the pods got soaked in WD40 which seemed to stop the water problem and Adelaide was achieved where BMW-less rider and his dog flew home to Sydney to battle the BMW warranty trolls.

I still have some good friends from that experience(was actually Matron of Honour at the female partners next wedding) and a healthy disrespect for BMWs reputation of reliability and customer support.

Al

For the question of the cafe racer ducktail, I quite like it when they use the factory tail but bring it forward to form a single seat space. It seems to match the flow of the tank quite well.  But a half inch of foam is not a seat I'd want to use.

Heya,
So basically its fine as long as you keep the filter oiled and cleaned regularly. 
You can get K&N filter service kits that allow you to clean and oil it.

Like he said use the original tail, looks much better than all the other aftermarket tails out there. Look here you can see how I have done so far.

Hi all,
Been another busy week getting stuff sorted.
The frame has been cut and welded, the original tail pipe has been reshaped and welded back in place rather than getting a round loop. Ive also lowered the headlight a little which looks a lot better.

Ive started to prepare the seat by making a tray out of fibreglass, hopefully I can build up the seat from the tray.

Have also completely stripped the fuel tank of paint and fitted a new petrol cap, think it looks great but was really hard graft.

So not a lots been happening over the last couple of weeks, I've been starting to make the seat but I am finding it really tricky as I haven't ever done this before and haven't used fibreglass before...plus its now dark and cold too :-(
I think I might need to make another one at some point but ill try to push though with this one and see how it actually looks at the end.

Wow, real progress and it really looks good.  Like others, I'm always nervous when someone takes a 30-year-old stock bike and... well, changes it all around.  But yours looks good. 

I'm anxious to see it progress.

I would very much like to know more about the fuel cap. Like what and how you fitted it.

Thanks for the supportive comments, I'm trying hard to make changes that I like but ensure I have a nod to the k and bmw. The headlight for example has a halo similar to the BMW 'angel eyes', little touches like that.
After the seat has been refined / made there should be a few big amendments.

The fuel cap is from flatracer, link below.
http://www.flatracer.com/bmw-accessories/4583973505

Its quite expensive but has been made beautifully and its something your going to see every single time you ride. They do another one that sits a bit higher off the tank which wasn't to my taste.
Delivery was quick and its literally been the easiest thing ive changed. It just bolts directly into all the existing holes.
I did order a brand new OEM fuel tank washer thing to sit between the tank and the cap to hopefully stop water getting in. Probably took about 10 minutes to swap over, if only everything else was that easy!

Hi Guys,
Looking for a smaller, lighter battery to replace the existing one & potentially move it into the seat hump.
Anyone able to recommend one?

Cheers

I've got a very small and light Ballistic Li-ion battery on my K track bike. It starts the bike no problem but as it's only small, the bike needs to be a good starter, you couldn't expect it to churn that bike lump all afternoon while you investigate a non start.
Have a look at my thread about my K100. There is a picture down the page of 3 battery's. The larger on is an Odyssey PC680 that weighs a whopping 7kg, the two smaller items do the job too.

I guess the Li-ion battery will be pretty simple to charge up whilst its not in use?

Evening all,
So its been a couple more weeks since ive updated but I managed to squeeze in a couple of hours this weekend to get some jobs done.
Ive installed the bar end mirrors, they're not perfect yet but give the bike a really nice silhouette & shape with them swooping down. Ive also mounted a Koso speedometer, its not wired in yet though. Im going to paint the bikes main colour in cream / ivory with red as an accent colour so went for the white dial with red rev counter, should look good in the end when its all come together.

I also managed to tidy up a lot of the cabling to make the overall look a lot cleaner & im pretty happy with it. I found that the previous owner had changed a few of the control cables such as the clutch, but for some reason hadn't taken out the old ones so when tracing through the bike so that was good shedding a couple of unattached cables.

Ive still been working on the bloody seat, I think ill have to buy one in the end but im hoping to smooth it all out soon with some filler and sanding but im not sure its going to work. Me and fibreglass dont get on I dont think.

Hello Dachwaton!

Just an idea, I use batteries from the solar industry,
the prices a perfect and mine powers on anytime in winter.
I'm using one with 18Ah, powers on much faster than the last one I had.
I found a link, but I don't know the uk market to much.

Are you sure they weren't spare cables? A lot of owners run in spares to make it easier to swap over while on the road should the original fail.

Heya Mike,
I don't think they were spare cables, they were all chewed up and nasty, I think they just hadn't bothered to remove the tank and faff around with tracing it all back through the bike.
To be fair, its a bit of faff even with all of the items stripped off and tank removed.

I have to admit that these batteries look a good idea but at 9.25lbs? That's a heavy piece of hardware hung out over the rear wheel, if it were mounted centrally on the bike it would be fine. The Ballistic 8 cell I've used only weighs 1.7lbs.

The Maplins batteries are priced right though and if a battery goes down on one of my everyday bikes,I'd give one a try.

Hi Guys,
Haven't been on here for a little while but will post an update in the next week.
I want to relocate the expansion tank so that instead of being near the battery, moving it to somewhere else.

Can anyone recommend an after market tank that will work fine with the K100?
Does the replacement have to be the same capacity or can it be smaller?
Any ideas on where or how best to mount it?

Thanks

Hi Everyone,
So been a bit quiet on here over Christmas and New Year with everything going on but I have been doing a few jobs on the bike over the last few weeks.
I have decided to give up on the seat, the more I tried to do and the more I looked at it, my attempt looked rubbish. I understand the process now but the whole thing was taking forever to complete so I decided to measure up and order one that I hope compliments the bike. At least with the one I have bought it will be perfectly smooth and should fit the bike nicely.

Ive now wired in the headlight and front indicators. Im happy with the indicators as they are quite small and subtle but give off a nice bright light.

Cafe Racer K100RS Build & Support InstagramCapture_6ec4352d-039c-4f86-b4dc-cbfa163120c4_zpsyjfn21ps

In addition to the light and indicators, ive also removed the second fuel tank tag to clean up the side profile. I noticed that quite a lot of the modified bikes kept this but I never really liked it so decided to remove it.
Cafe Racer K100RS Build & Support 20160111_213947%202_zpsika7lep0

And the other modification I completed was to move the coolant overflow / expansion tank. Because im relocating the battery, the original coolant tank wouldn't fit anymore so I went for something different, somewhere different. 
Im not 100% sure if ill keep in the same location but I used a carbon fibre Oil Catch Can as the coolant overflow tank which will hopefully work quite well. Will I need to allow a little air in this so the system can 'suck' the coolant back into the system?

Next items will be fitting the horn, relocating the ignition and seeing how the new seat looks.

The wire is non OEM, ...the way it's connected, it's 12V+ unswitched and unfused.
Remove it.

Thanks,
I didn't think I pulled it off anything as have been very careful through the build process and couldn't figure out where it might have come from.
