So the project isn't dead I've just been extremely busy with work.
Finally found a twin rad setup that works - https://www.ebay.co.uk/itm/252198042402
The bike is currently at the machine shop getting the engine brackets and radiator brackets made up.
And this arrived today 
It's back!!! The wheel is finally back!!
So this is a 19" yz excel rim on a dt125r hub.
Fits nice even with the wheel pushed althe way towards the engine there's still clearance.
Got the new bolt for the dog bone to mount it to the frame from fowlers
Just waiting for the rear axle spindle to turn up so I can get the rear wheel fitted
I wouldn't bother with that. Seen them snapped quite easily. I would use a ground anchor and chain when at home and a chain around the wheel when out. Always try and chain it to something when your out. Remember even your own garden isn't safe.
When I lived at my parents we had a large garden with a dog that always barked at strangers yet one night I found my motorbike was missing!! Ran up the garden at 3am in my pants to find her resting at the side of the road on the kick stand. Guessing they went to get a van. I was very lucky
So this turned up today 
Yeah fits but needs a few modifications. Needs custom head to frame brackets and the front engine brackets.
The decider was the fitment between the swingarm and that fits no modifications 
@Zrako calum's method works great. i've got some close up pictures so you can see how it works

i used a stock dtr lower bearing in the frame with the yz forks and the stock yz top bearing sat in the new bearing cup
How much did you pay just out of interest?
I picked this up - 
Don't really know what gas gas model it is apart from being 320cc.
Bought it at 5pm for £400
Crashed it in the field at 6:30pm ripped the back off and bent the wheel.
Sold at half 7 to a guy that races them for £700.
lol not really sure what I had.
Before I messed with my 2000 dtr build quality was great. The 3mb I think it was? Never let me down
Welcome
Hi all,
My names Gareth and I'm 27 from the Isle of Wight, uk.
I've got a dt125r 2000 and a drz400 2006
A picture would help us see what you are seeing
I used a hel set like this with no problems - http://www.wemoto.com/bikes/yamaha/dt_125_r/88/picture/hel_front_hydraulic_hose_-_standard_set-up/
Be careful with discs I can't remember what type it was but once I went for a cheaper disc and it would rust over night where as the more expensive ones didn't rust at all. Sorry not sure what the coating was called
Haven't posted in a while but things are still slowly moving .
The wheel has been with the builder for a week now so hoping to have it back soon.
Ordered the wrong front yz calliper doh!! So sending that back and ordering another. They calliper carry is wider on a 98 then the 97. My forks are 98 
.
The yz exhaust has arrived as well but I forgot to take a photo. It doesn't quite fit might need a little bit of heat and some bending to make it work but it's not to far off.
So here we go once again i'm rebuilding the bike
this is where the project starts:
i have already made a start and thanks to @Calum 's bearing cup guide i have started making the yz125 forks fit my dtr.
so lets talk forks..
i had the bearing cup made up at a local machine shop using Calum's design. i took the design down with the frame and the yokes. the measurements had to be adjusted to make the cup fit the frame as the size wasn't correct for my frame. i'm not saying his design and measurements was wrong in anyway it just wasn't quite right for my frame. unsure if it changes throughout the models slightly.
so as the yz125 stem is longer and the stock yz top bearing is large than the dt frame the bearing cup is required to make it all fit.
i used a stock yz125 top bearing and stock dt125r bottom bearing to make it all fit. no modifications are required to make the dt bearing fit the stem it's the correct size believe it or not and theres no play.
the axle spindle is larger on the yz forks so you will need to use the yz front wheel.

Hi all so here we go.... my 2000 dt125r
i've had the bike since 2008 and it love it.
a picture from my last overhual in 2012
some pictures of me having fun the day she got her mot after the last over haul.
I've really loved this bike and i took good care of it. i was riding it up until feb 13 when i got my car licence and then it sat.
during this time i managed to find a yz125 engine that i thought would be great so i sold my 3mb fully running engine to a friend for £150!!!!! DOH looking at the prices of them on ebay now i feel a bit stupid.
TBC
Very nice it's hard to find one that hasn't been hacked about. Can hardly call mine a dt anymore lol
@Calum was still a size/rez issue but lets you get to 100% on mac
Right lets try again...
so these turned up yesterday
had the headlight cowling a while but i finally ordered the others.
all brand new and genuine.
i haven't ordered the front mud guard yet as i think i might use the more sporty looking yz one.
Whora hijack!! Haha
@scrimsmustang just bolting a light to a yz isn't fun. It's all about building something your way that no one else has.
I'm not some one that can just buy and sell bikes I get attached to them. I've had my dt 9 years and it changes with me. No other dt would ever feel the same. Its like having a child and watching it grow.
@Calum ah ok thanks annoying. Has it changed? I used to upload from my phone before.
