@Biker_123 ahh safe, I can put up the DXF files if you want some? Got 2pairs cut for £10 down my end.

@Biker_123 DXF files were drawn using Solid Works, I'm not sure what programs you might have to open these, but send these to any good company and they should know what's going on.

Enjoy!
Next up is a custom intake, really needed I reckon 32-36mm intake,
Will put up a plan after I get it made

What an awesome build man im loving this! top job m8y

How did you make the bracket for the front brake
-
@vtrn_raptor Hand sawed. filed, and machine sanded, you will need a Pillar drill!
I've only got a sketch you can follow, dimensions are rough and only for a YZF125 caliper that was modified. should be 68.5mm of the fork. I use 15mm spacers now of the hanger.
I started with NEV's example for a DTX caliper, and modified the fitments. If you have a DTX caliper then NEV's dimensions should be on point for you.
Create mock-ups and check your offset position thoroughly, CNC Steel alloy is a better option than ally.

I really need to find someone who can make me one for the standard dt brake caliper as I don't have to tool to do it myself:(

@aidan1996 I recommend it, try and learn a bit about Ignition Timing and Powervalve setup before you buy to make the most of it.
Ignitech systems are made to order, so just send them an Email and state your desired Model and/or loom type.

Some little bits.
Removing material to clear the flanged nut I'm using off the fork leg for the correct position. Renewed this bit a while ago, the YZF carrier is not the best idea.
Finished setup for now, Lathed up 16mm Brass spacers and fitted together with 10.4 HT bolts.
98' YZ 250 1/4 throttle with billet alloy throttle tube, is plush like em snappy
New ceramic resistor.
Trying to keep Jap with a Denso W27ES-U plug. £1.70!
Call me the 'Artful bodger' Ran into some issues just using a capacitor to run the Ignitech. So strapped in ol' faithful in what's left of the only space available on the bike.
Slowly rebuilding my TM32. Sanded, wet sanded and polished internals.
Satisfied like glass. Giving a helping hand to the inevitable ingress of dirt to be combusted.
Remounting the WR rad, cutting the thermostat housing down, deleting the oil tank cap fixture from the support and shortening the rear radiator outlet futher to clear the tank. Then moving the whole thing forward to sit flush and safe.
Having alot of fun tearing it about, led me to ignore a serious issue. After letting the chain eat my original WR200 chain guide and very good condition Delta-box swinger, it was time to go back and fit plan A.
Drilled and M6 taped new mounts. Didn't feel like sacrilege after fucking it over already.
I wanted to do this for ages, fitting a YZ/WR 98'-02' chain guide looked to fit in my head. Can now replace it without having to take the swinger off, and readily available to replace now, as WR200 and early YZ 1990-94' sliders are rare, or silly money new.
Ugraded to RFX slider in blue, made from a hard polypropylene instead of silicone rubber. Should do the trick.
Running the airbox door removed and older 3MB airbox tract now with a 450 Main jet can you believe. It's now absolutely perfect with peak power dropping away at about 10,900rpm. She sings. Ready for my new ported top end. Looking to go full road racer at 12,600rpm with the larger carb.
Shortened the chain, back on a Steel sprocket with a 45T 520, good for 80 again which was missed,
I always preferred the original clutch cases, got a nice oil pump housing design. Had to use my 4DL one.
Standard (left) vs EBC's heavy duty clutch spring. Good upgrade, firm clutch with a quicker release.
New EBC clutch plates a while back had trashed my gearbox oil, found this, cause race bike..
Threaded insert and bolt for oil pump delete, re-sharpened foot pegs and brake pedal from the trail bike days.

Excellent work @Darty !! Good to see you doing more work to this beast.. Kinda worried now incase my chains been eating into my wr swing arm i will need to check tomorrow I've just been using the DTR chain slider on the wr swing arm hope its all good as I've been using the bike 24/7 lol.. Don't fancy getting rid of the capacitator by any chance now your using a battery again!? My capacitator is lost in the woods somewhere obviously wasn't secured enough
-
@Biker_123 I've been using mine to get to work everyday, such a laugh I had it jacked up to high, like a 93cm seat height through the chain geometry out, swing-arm was too big for front sprocket clearance it's alright otherwise.
shit man, get it bolted it under the seat xD I definitely got to hang on to my racing Capacitor, it was hand made from Greece
-
@Darty No problem haha had me worried about my swingarm for a bit there
.. I'll need to pick up another capacitator my local motorbike shop does them but needs to order them in so takes a while! Oh for sure it'll be getting secured better this time round 
really need to do some more work on my project and replacing the dog bones is high on that list along with a 520 chain conversion.
