I'm not going to lie, you use your bike a damn sight more than I use any of mine! I mostly cycle/run everywhere.
No you don't need clutch springs for the Athena 170 kit, so long as your clutch is healthy you should be fine. That said, I run the stiffer spring setup, along with the EBC Dirt clutch plates.
Been out on my DT today and it is running CRISP in this weather. Really hurtles along!
Yeah it's satisfying riding the bike with a motor you've put together.

I’m not an original’o’phobe myself, personally. I just think the OEM ones are better than aftermarket replacement ones. Not including titanium or stainless upgrades, which I would use if I weren’t so ‘broke a$$’
I do get people wanting originality on classic things, but I’ve always got the most out of doing my own thing. Cutting, welding/splicing and usually Matt black (cause of the broke ass thing
) with the lettering on the tyres picked out in white (child of the 70’s!)…PS! Do the clutch springs need upgrading with an Athena kit? Or is standard fine?…

Didn’t get owt done today. Bike was running properly crisp tho! It was like the cold dense air was a nitrous hit for the old bee~atch! The bits & bobs motor I’ve got in at the moment has done me reall, really well considering the absolute state of it! I’m just coming up on 30,000miles since I got and built the bike & engine!…
All the hassles I’ve had and IT has never left me stranded on the side of the road. Bless!!…I’m quite looking forward to the new chapter in Its incarnation . I’m hoping it’ll run like a dream from here on out

I seriously can't get over how much you ride lmao. I don't think I've done 30k miles in all of the vehicles I've owned.
I still need a gudgeon pin for an Athena 170 piston. It’s 16mm x 56mm. The only one I can find is 16 x 57mm…
If anyone has put a new piston in their Athena kit and still has the old pin please let me know. I can’t do any more to my build till I get one
…Cheers Peeps!…

Why don't you take the 16x57 and machine off 0.5mm from each side?
I remember the pin from the kit has a little play when installed with the circlips,maybe there is space for that 1mm. -
@SpookDog I only recently threw away an Athena 170 gudgeon pin that only saw a few hundred miles on it
Well f@nk you very much! Wasteful Torrie!
…My plan B!
…I’ve got one ordered earlier today, once I found out my siss’s card worked. She’s a fuxin heroin when it comes to keeping me afloat!
It looks like there is enough room to fit the 57mm pin, I’m just not clued up on heat expansion & the like. I can just imagine it popping off a curclip when it comes up to temp! 🫤 …Edit: I forgot to ask about Athena replacement piston rings. Best place to get them? I understand that they’re specific to these kits as they’re 1mm thick/thin? Seems churlish not to fit new ones if they’re available and not astronomicaly priced …

You can see that it’s been used either way round. I was just wondering what the reason is? If it aligned with the seal I could understand, but the wear pattern shows it doesn’t…
Actually, saying that! It looks like they’re not symmetrical! Strange!

Now I’m wondering if it’s original to the Dtr? It looks like it was used in a different engine, from the wear on one side to the other!
I don’t have another one kicking around that I know of. I’d like to know the measurements of a proper one so I can compare. It did skim off a sliver of the seal when I tapped it in. I though it was because it was a NOS seal and a bit hard. Guess I could of been wrong…Edit: then again someone could of just tapped the seal in too far, or not enough one of the times! Arrggghhhhh!!! 🤪

@SpookDog
There is no reason for that groove there,no gain in lubrication or anything else. It's a spacer for seals. It must be from a wornout seal.
I had something similar on the spacer that seats the seal at the external chain sprocket. It looked like factory groove. -

Sorry bud, I disagree. I know, and have had, what you’re talking about. This isn’t wear, it’s machined. It’s a perfect V.
It’s just 1 not 2 like ‘normal’ wear would be?With the new (nitrile?) seal in place flush with the casing the groove lines up with the outer lip. I think it actually gives a lot more surface area for the outer lip of the seal to mate up to…
I’ve only had the wear line on single lip seals, the sprocket spacer has been my experience as well. Now I’m wondering!…
I just can’t get over the amount of ‘curve balls’ this bike has given me! The learning curve has been like climbing K2!
I do appreciate the input though, please let me know your thoughts!…

It's a wear groove, seen it many times on cranks etc. your lucky on the DT it's a removable bush/sleeve, that can be replaced. I'd turn it so the seal is running on a smooth section of the sleeve.
That is what I first thought, but it’s so perfect. Also it’s a double lipped seal so there should be two. Can you understand where I’m coming from?…
——————————
When I saw it on the front sprocket spacer I thought it was wear. Now I’m starting to wonder. How much rubber would it take to wear into steel?!
-
@SpookDog I've updated my original post, I was having a hard time locating the part in question (being thick).
Anyway I think it's part number 25 you're after and it looks as though, no there should not be a lip there.
You can get a titanium replacement:

@SpookDog I agree it looks machined, no idea what it's doing there but you can see how the crank seal lips have marked a wider track next to it on both sides, obviously at some point someone has rebuilt the engine and flipped the spacer to have a fresh surface running in their new crank seal.
Be that as it may, in these kinds of situations where a hard material runs against a soft material, it's usually the harder material which experiences the most wear because small fragments of the hard material embed themselves in the soft material and then behave like boulders stuck in the bottom of glaciers which is what formed today's mountain ranges as they moved slowly downhill. That's why if you go looking for an aluminium 3ET DT200R swingarm for your DT125R, you have to be very careful not to buy one which has had the shock protector mudflap rubbing against it as this can make the back of the linkage pivot area dangerously worn. KTM also had this problem on their modern Enduro bikes leading to people gluing a 50p piece onto the back of the shock pivot mounting. I didn't want to trust JB Weld in an area exposed to lots of mud and chain lube so I cut open the plastic sleeve from inside a reel of sticky labels and zip tied it in place.
Ti is a nice thought but I'd be wanting to look at its material properties, suitability for running against rubber etc. I think you can still get the OEM one from Fowlers for reasonably cheap.
