Only ever buy genuine cables. Aftermarket ones man...pain in the arse.

Just an update that things are still going well with the bike. It’s running sweet as nuts!
The one strange thing is that I got so used to riding at 5-6K RPM that I still haven’t taken it over 6K, even though I know it’s sound now! I mean it cruises at 60mph at about 5 ~ 5 & 1/2K! Depending on the windy weather.
I don’t know if I’m being cautious or have developed a fear of the redline!
I keep telling myself that I’m waiting for the dry spring roads and a new set of (non square) tires!…
The clutch cable snapped again after only 8 weeks of use. It’s a Slinky that let go at the nipple. The last one saw me through 2years and 20,000+ miles, go figure!
I’ve got another Slinky and a proper clutch perch to put on. The one that came with the bike isn’t righteous, the lever just doesn’t fit right and it only has one pinch bolt, as well as fouling the grip slightly…I’m neck deep in fitting a new kitchen sink, work surface and tiles, ect to my siss’s kitchen at the moment, as well as building cupboards!
It’s the least I can do, she got me the Dtr when I was down on my arse!…Still haven’t found a dry enough spell to wash and ACF~50 it yet!…
Got to keep busy or go crazy looking at the state of the world!…

The clear bit is where my bag strap crosses my shoulder…
It’s weird that it back sprays up?!…

@Calum they’re very hit and miss. I’ve used pattern speedo cables and Rev ones and had no issues. IIRC it’s always the throttle and clutch to watch out for.
@SpookDog glad to hear she’s all going well! Don’t be afraid of cracking the throttle open! One of my favourite memories was when my bike wasn’t running 100% I’d looked at loads of things and couldn’t find the issue I took her out for a ride where I said fuck it went on to the bypass and just held the throttle wide open (after all what’s the worst that can happen). She chugged coughed and splattered for a good minute refusing to Rev past 5/6k then suddenly bang. Off like a fucking rocket. Dont think I’ve ever been caught so off guard. Moral of the story mechanical sympathy is great but you’re doing a two stroke a disservice if you don’t kick its head in occasionally

@SpookDog This splattered jacket business is a timely reminder to get your Autolube pump rebuilt and refitted. As discussed previously, premixing is always a compromise as you're stuck with whatever oil ratio you decide to run at that time regardless of engine speed or riding style. It's fine for competition bikes as they usually spend their time being used for one particular riding style or another so a trials bike spending most of its time at low revs riding over logs and oil drums can get away with 100:1 terpentine, whilst a YZ125 being given the beans everywhere to equal the lap times of a CR500 positively laps up that 35:1 treacle. A two-stroke road bike has a more complex set of requirements, most of the time it's being ridden to Highway Code standard in traffic but sometimes you need to bang it down two gears and pin it to overtake slower vehicles. So the mechanical engine management of Autolube which constantly varies the oil ratio according to how the bike is being ridden at the time equates to a much cleaner running bike and a healthier engine.
If that jacket can be washed without losing its waterproofing properties, it would be a good experiment to do this at the same time as getting your oil pump back on the bike and then seeing if the splattering comes back. IIRC we looked into DT200R vs. DT125R oil delivery rates a few weeks ago and they were found to be virtually the same? Here's a link to the post:

I haven’t even fitted the new clutch lever&perch and cable. I’ve been using the old frayed one from before…Priorities dictate, Yada ~ Yada, Yada!…

Oddly enough I see a young guy on an rs extrema, I passed him some compliments then next thing you know hes blapping the throttle going around a tight corner. I could help but think of your comment

I’ve had 3 or 4 heat seizures in my time. I’ve always managed to whip in the clutch In time. To the point where I could kick it over straight away afterwards…Used to hover the clutch in a car as well…
————————————-
Just fitted the new clutch perch and lever, as well as a new Slinky cable. The action feels like a hot knife and butter now! I never realised how wrong the one it came with was, or how it used to bind…
If I could afford £50 for a genuine clutch cable I would. Or if I had a genuine outer I’d fit a stainless cable and solderless nipple.
The one cable that I will only use genuine is the throttle. My bike came with an aftermarket one and it’s shite. Not so bad if you’re pre mixed but absolutely necessary with auto lube… -

I have exactly the same calliper on the front and rear (30mm piston) but the front brake only has 1/3 of the effectiveness of the rear, as far as I know this is totally back to front! The front is normally 70% of the total performance, no?…
I can’t get my head around how woeful the front brake performance is. It makes no sense. They both have Brembo carbon ceramic pads…I really want to find someone who does waterjet cutting, or something similar, to make a rotor that will fit the Dtr’s front hub and take a floating disc from a donor. Whatever size/make that is the most inexpensive/common. Then design an ally mount to couple it with a Brembo 2 piston calliper, or such, that will fit the spoke to disc clearance…
Somebody needs to do a decent affordable upgrade!… -

Brakes on my DTR were horrendous.
Don't have that problem any more, bike stops on a DIME!

I don’t think that it is. There’s no play on the lever, let alone sponginess, but I don’t think it’s getting the full pressure of the system at the pads. I can’t see any other reason…

@SpookDog In practice the linkage bearing sleeves often don't wear so if you vernier your originals up and they're still close to 20mm OD you can just get the linkage parts separately. Relay arm bearings:

Linkage bushes:
https://simplybearings.co.uk/shop/p142950/MB2020X-Bronze-Backed-Steel-Bush-20x23x20mm/product_info.htmlDouble check all of these dimensions before ordering as it's a while since I did a DTR linkage job but I'm pretty sure these are correct. Just rip the piss out of me if they're not.

Is there anyone who knows the sizes of the needle-roller bearings and the phosphor bronze bushes definitely? The only way I can find out is to strip down the linkage first. I don’t want to take the bike off of the road though. Also I’ll probably destroy the bearings and bushes during removal! From what I remember the bearings were loose rollers that I had to stick/pack into place with grease, only the outer ‘cages’ were drift~fitted inside the linkage to frame union. They were very thin gauge metal and easily damaged…
Ta!…
PS. Is the 20mm inner or outer?…
Edit: The inner is 20mm on both bearings and bushes. Are the bearings 23mm outer like the bushes?…

I’m just praying that the sleeves are in good enough order (especially the roller bearing one) to match up nicely
