Thanks pal your 83 looks mint aswell. I got the rad shrouds from nightmare racing and the rear fender off ebay there all just abit different in colour needs a few bits can't get hold of aswell like the rear brake stay bracket and now a new torque rod wire for the rear brake as its snapt through what I think is not having the brake stay on

[motopunk]

thanks...and she runs like hell with her 43 hp´s and my little mods ...   
i ve changed my rear brake cable into a handmade 6mm brake rod , since it was broke at a race in 2012. i had lost my leading position and to quit the race without rear brake.that solved any problems, that the cable had...
 
in 2013 i started to race with my ´87 and some problems in the evo-cup. the ´83 was always the back up bike, that saved a lot...
at least 2nd in championchip,,,

Ye the brake rod sounds like a good idea as for the rear brake stay I could probably nock something up for that would just prefer the ome part really here's a pic of the snap on the cable holder

[motopunk]

yes this was exactly my problem ... bang and the rear brake was gone at a downhill straigt  ...  at the same day i made a special bracket to use the broken cable for the 2nd race..  was my big luck that they have a garage beside the track with some tools and material that i needed ... 

later i will post a pic ...the cable is still in my spare parts box ...

[Bobbyevo]

Thanks could you put up a pic for the rear brake stay aswell so I've got something to go off

[motopunk]

same problem:  the cable of my 2nd ´83-kx250


my spontanous solution made between 2 racelegs in 2012. worked great..





and one of my handmade rods for deplacing the cable..  
simply made of 6mm steel rod ..

and a little bit ´83- action from 2011...    was a bad camera ...

Thanks very helpfull ideas lookin at the pics looks great on the start line on the vids
It's the rear fender what does it for me I think and I was born in 1984 aswell so the bike sorta was for me I have a little vid of it running while I was sat on it but none of it being ridden yet ill get the vid up 

[motopunk]

thanks...  2 times holeshot against bigger bikes   

and i never thought that it performs so well, as i picked it up in bavaria near munich . at this time it was simply an scrab-assembling  , missing the carb, broken 3th gear, both fork legs were bend... 
were a lot of work... and now it starts always with max 3 kicks in cold or warm .
i was realy amazed, how powerful this 30 years old engine is performing.
you will learn to love it, if you ride your bike 

[Bobbyevo]

Ye can't wait to get it done so I can go for a proper ride out with it
At the moment I have stripped it down again to get the parts I need and give the frame and a few other bits a good going at but there is a lot I need to do aswell. The forks need rebuilding one of them seems abit longer than the other the rear shock is nackard and I think it will cost too much to rebuild do you no of any other good shocks that will fit also struggling to get hold of the both of the mudflaps for the rear the cylinder has been welded/fixed in the past but i can see a hairline crack so that needs a good looking at and a lot of other things I can't think of at the min
Before the strip down

[motopunk]

the hairline crack should be welded again with the right heat treatment to the aluminium... 

my bike came with an öhlins shock as i picked it up.  the shock in your bike looks like an wp aftermarket shock or is just taken from another bike.
the stock shock looks completly diferent ... 

older suzukis and hondas used similar shocks . u should compare the length and diameters of the mountings...  most shocks could be modfied to the right length in the case, that its longer as needed... 
so i think , first you should find out, which kind of shock is in your bike and let it rebuild ..
with buying another used shock, it could be, that you might have a 2nd shock that needs rebuild..
