Please help 

I just thought of this, please tell me if this is a good way to do this or not

If the K100 members would be so kind in helping me, I want to start restoring/fixing the bike and as a newbie/novice I don't have all the knowledge to do this on my own

my idea, and from the help of the members is to start at a point and work my way from a back to front or top to bottom /whatever the right way is. (but to have a certain order)
 is to check/fix/replace/restore/ the specific part /item - I will take whatever picture requested that members of the Forum can decide/help/give me advice what needed to be done.....  (I hope this is a good idea) 
(buying of ebay will most probably be a problem for me - don't have a credit card, and have no idea how ebay works ) here is SA is engineers, bike shops, and also part stores, this wont be a 2 week project, it will take time, obviously money (as i dont have won the lottery yet, saving every month as I can) and patience - yes I know this



obviously 1st without stripping the whole bike (go around the bike take pictures) 
then as time progress to start going into more depth on more specific items (better detailed pics)

I have no idea where to start, or what to look at, however I do have mechanical skills, and I tend to fix more stuff than I breaking them  


generally if I get stuck , I think outside the box, and find ideas/ think of a way to fix the problem


please feel free to encourage/discourage/give advice/rate my skills/request pics/show me alternaitaves







please start a list (please feel free to copy and edit the list) of things I need to do, take pictures/ video's,


i started  2 weeks back with the k100,

1st problem i ran into was the fuel pump was stuffed, (the rubber went to goo)
replaced with a universal pump, with fuel hose as the rubber damper, and some cable ties

I would say yes to that it is the earliest number I have seen and was made before they were released for the general market.

Timing covers come up on ebay from time to time. They're not in huge demand so go fairly cheaply. I once bought one for £3 on ebay. If I see another going cheap I'll let you know and if necessary I'll buy it and post it out to you.

Three-Bond (Drei-Bond) sealant is used as opposed to gaskets.

As your bike is such an early example, I'd be tempted to get it back to as original as possible.

If originality is your goal, you have some work ahead.

The front wheel is wrong, so too are the mirrors and front indicators. If the bike was a naked 'C' model (which I would expect given how early the VIN suggests), the handlebars need to be changed back to 'C' version.

As pointed out, the seat and tail unit are from a later bike and the silencer has been cut.

Then there's the colour of the wheels, they should be plain silver.

What you need to work out is whether it's worth it financially set against the desire to own a very early bike in as near original spec as possible.

ok maybe I haven't thought it trough as you mentioned it can become an expensive exercise  Sad 
time is also an issue, we all have our day jobs, so weekends will be the time and place i will be working on the bike
I think that the main goal it to take what I have, and 1st repair/fix/replace/ask/beg/steal what is broken/   what needs to be looked at and fix that :-c: , get it mechanically sound  , and get it presentable (make it pretty) again  

maybe the above is a better way to start off? please don't discourage me too much, i understand that i need to hear this as well, but at the end of the day , i think if i do a little each time with your /k100 members help, i will find success at the end of the day and will start seeing progress.?

I think that is the right way to approach the job and over the next year or so gather up the needed parts and maybe get it back to original.
BTW if you want a cam chain cover I can give you one but postage is up to you to pay.
PM me any details and we can organize things.

This is a side on of an RT but side covers and rear tail section and seat give you an idea of the seat etc that is right for your bike.

Hi Rick
 
thank you this is a very generous offer
 
I would love to have this part, how ever if it is the correct part (im not to sure if there is different models), I wouldn't want to take it if it does not fit my k100, do you want me to mail you pics/engine number?
 
 
I'm also not sure what the shipping to south Africa will cost, can you please find out for me? then we can take it from there
 
thank you once again for your generous offer

I never noticed before, that the lower section of the tail unit was colour coded on the early 'C' models.

Hi rexst,

Having refurbished/restored a couple of K bikes, and several other motorcycles, I always weigh the cost vs resale.  Here's the thing:  You would put a lot of money into a full resto back to original, especially since parts are difficult for you to source.  At the end of the day, when it comes to selling the bike, a prospective buyer won't pay you much more for a fully restored bike than a nicely tidied up slightly modified machine. 

I would agree with your plan to get it running and not leaking, and pick away at the bad bits as time and money permits.  Frankly I like the newer tail, battery covers and seat better than the originals.  Reseal the cracked timing chain cover.  Remove those awesome Rolling Eyes  decals from the tank and covers, and try some paint stripper sparingly on the wheels to remove the red paint (do you have Q-Tips in SA?), and polish the stainless muffler.  This will cost you almost nothing, and will improve the cosmetic appearance a lot. You still move the project ahead without wasting any money or making non reversible mods.  (I suspect what you really want to do is RIDE?)

+1 on Tri-Bond...

After fixing the oil leaks, the next thing I would spend money on would be correct handlebars and then start looking for a correct front wheel.  That one looks a lot like an R series.  I would suspect you should be able to sell that for the same amount you pay for a K wheel, so that could be cost neutral. 

There are a couple of SA K100 owners on this site, they may be able to help you access your parts. 

If you are going to have to order parts from somewhere, you may want to set up a Paypal account to pay for items.  Simple to do, but I have no clue if it is supported in SA?

Cheers,

clubbie

The front wheel and discs are from a Suzuki of around the same vintage.
Looking at the damage to the cam chain cover I would say it has been involved in a front on smash and a replacement front wheel was not available.

You'd do well in the spot the difference comp.

Same wheels as my old GSX 750ET used to have
Different forks?

I am flying out from Perth on Wednesday night 11th December.

Don't mind taking a timing cover off my K75C if Rick G can confirm they are the same as on the early K100?

As far as I can see the only difference is they are either black or silver and thats it.

Cheers Rick G. Can you give me an indication of the weight off your spare cover (assuming you have it available as an item and not still part of an assembly?)
rexst - can I leave it at a Mate's place near Randburg for you so you can liaise with him and collect when convenient for both parties?

Hats off to you rexst! from one newbie to another. It's daunting at first I know, I didn't wanna remove  anything from my K at first, but I'm now a little more comfortable being up to my elbows in K.
I'm lovin' your commitment, I'd love to get down to the frame myself and paint/ clean and seal everything that I put back on. Unfortunately I'm trying to get mine to reliable commuter state first. After that maybe K number 2 can be got. I reckon i'm not alone here in thinking a second bike is a GREAT idea. Ride one work on one. bounce 

Wonder if I can get the Missus to see it the same way. 

Keep up the good work,

Oh and a "Big Ups" again to the K100 forum you guys rock!

Jez.
