So Close!...

@SpookDog This looks to be coming on well, shame the weather isn't good enough for painting but Lidl spray paint is exactly the same as Smoothrite (but cheaper) so once all the festive tat is sold, they might have some in by the time you can get the spraying done.
Good time to Seal-All the carb-to-airbox rubber in the meantime; usually the rear shock has to come out to remove the airbox and you won't want to wrestle with it too much once the frame is painted. The rubber is downstream of the air filter and Yamaha made a poor job of sealing them at the factory so potentially your engine can suck dirt if this hasn't been done.

I understand where you’re coming from but personally, I like to have it removable. It just makes it easier for the times I do get around to cleaning it all up. Mine gets filthy even with good filters properly maintained! (Tho obviously not frequently enough!) the little crimped tube helps with flushing out though…
I did manage to get a last coat of etch primer on after the rain stopped! I forgot about Lidles paint! Hammerite smoothrite can be so very expensive!

Tomorrow is sposed’ to be dry

@SpookDog Your frame is in little better condition than mine was on the project DTZr thread.I used paint remover for the paint,acid for rust removal even inside of some of the tubes where was possible very good soap water cleaning.
Immediately drying in the sun and torch heat for the insides.
Using a big syringe I poured rust converter in every tube was possible until was running from the venting holes
After drying did the same with cold zinc paint for rust protection.
Wire wheel on all the frame,cold zinc paint then black paint.
Also had to repair drill holes at the back of the frame,broken bolts,damaged threads and straighten the frame where the back sub frame/rack attaches.And this was a good frame,2 other DT's I saw before buying were raped literally.
Here the DT's were used for serious off roading even competition,races and a lot of bad 2 stroke tuners that literally killed the DT's like flies.
I wish I had condition like most of you buy. -
Didn’t notice your post about the 200 carb, interesting!…
Again! I wish I had a welding kit or gas. I really need to close up and drill, then tap so many fuxed threads on the frame. Also, Id love to see a known good frame so I could compare my ass end. I’m sure that mine looks like a Gorilla sat on it (& bounced!)…
The last thing I wanted to do was paint at this time of year. I couldn’t leave it the way it was for another 6 months though. Not in good conscience 🫤 …

It’s actually etch primer, a brand I’ve never heard of before: Upol
Gorgeous colour & finish ain’t it? 90% of my bikes have been satin black, I went through an olive drab spell as well
️Kudos on doing your frame by hand. I know how much is involved, just with the paint stripping! I’ll have to read through your thread…

Round one! In the White corner!!
…
1 & 1/4 cans down. 1 & 3/4 to go! (Plus 250ml brush on for those bits)…
It’s not pretty, there are some small areas of orange peeling, tho nothing big. As long as it’s protection till I can do the professional ‘thing’
…Day 2:
What kind of idiot sprays paint I the windiest day of the month?!

@OllieDTR
Cheers bud! It’s ok if you have 20-20 vision, 20% visibility and are 20 foot away! …No it’s smoothrite. I really liked the ‘feel’ and quality of the Upol. It and Hycote are 2 of the best aerosol cans I’ve used. I don’t know if it’s the pressure or the nozzle but they are really well ‘atomised’ and all

Cheers buds!
I used 2 cans (2coats) of zinc primer first, then the etch cause I had it around from when I was going to paint some ally. I’m just going to fill in any crusty spots with a brush. Those impossible to spray places where you end up overloading the surrounding area…
Last pic I swear!…Thank fux I greased up the lower headstock race! Before I forgot to take it out then painted the frame!
Edit: I just checked the swingarm bearings and seals I put in 30,000 miles ago and they’re still sweet! No water or mucks gotten in from either side of the swingarm ‘knuckles’, just good clean grease
…
Got the linkage to check next, after I clean and touch up the paint on the chain tensioner end of the swingarm…Edit again: linkage is just as good!…
Does anybod know if the All Balls kit includes the nylon bushes, as well as the steel bushes? If not are the nylons available anywhere?…

@SpookDog Yes you can, I changed my swingarm without removing the shock and relay arm once. I'd arranged to go out riding with some mates the following morning, was just giving it a wipe over at about 10pm and found a crack near the relay arm mount so had to swap it out sharpish; luckily I had a spare with decent bearings. Still did the side clearance adjustment because I can't help myself
Another bulk order of 2am stress!

@SpookDog Same as an '85 YZ125, All Balls part number 29-5027, plenty on eBay around £15. The circlips are quite difficult to remove, I had to get inventive/sadistic with a set of jeweller's screwdrivers (which weren't much good for jewelling once I'd finished!):
https://www.allballsracing.com/29-5027.html
Simply Bearings sell the grease seals for this and the linkage for cheap (the 20 x 27 x 5mm ones for the linkage are better than stock as they're double lipped with a garter spring), it's quite handy to have a good supply of these:
Another hack you can do when assembling the linkage/relay arm is to flip the seals so the garter spring faces outwards away from the bearing; the lip without the spring is just a dust wiper so you can then cut small sections out of this with Swiss Army Knife scissors (best/sharpest scissors I've ever used) or one of those leather punches so when you re-lube the linkage bearings with a grease gun, the hydraulic pressure is less likely to force the seals out. The grease is free to pass through the gaps in the dust seal lip (now on the inside) and lift up the lip with the garter spring in its bid for freedom! The sprung lip then retracts, retaining enough grease inside the bearing and keeping dirt out.
If like me you're ham-fisted with the grease gun, it will still try and force out the seals so you can also hacksaw a section out of an M20 washer and insert it in the gap between the tiebars and the arm during greasing to prevent this (with the linkage bolted together and the seals where they should be, you can actually move the tiebar/sleeve assembly 2-3mm side to side; useful after you've greased up everything as you can move it fully each way to make it splodge the excess grease away from the bearings/seals, then clean it all off thoroughly to prevent any getting on the rear tyre).

Thank you bud!…
I definitely need to make a really sharp pick, to try and lift an end. I just need to remove the swivel bit from the old one to reuse, just until I can get one ordered and posted. I can’t wait to get this bike back together and ride it!
The shock I’m using had a solid steel ‘bush’ in it that I had to put 2 cuts into, just so I could remove it!…
I really appreciate the lube tips you’ve posted, especially the PV cable oilers with stainless steel inners! It’s so important but so overlooked. I bought a swingarm that was going cheap because it is one with the grease nipples on. Why they stopped fitting them is beyond me…
Will be interesting to see how it holds up over what's left of winter with the etch primer.
