So Close!...

@Stevie-Wonder Agreed, it's important to give any two-stroke a good thrash through the gears at least once every time you ride it to blow out all the accumulated gunk.
@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:
Cheers bud! I’m sorry, I totally forgot. I’ve been so busy with my Sisters kitchen that I’ve put the Dtr on the back burner!
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!…

@Stevie-Wonder Obviously haven't had a two stroke seize on you...

@SpookDog Understood bud, only so many hours in the day!
I'm pretty crap at anything building/DIY, post up some kitchen pics when you're done

@Calum luckily not, I’ve seen videos and learned to ride with my fingers over the clutch just in case, but I’ve never thought about it suddenly happening mid corner.
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 don’t know if it’s a bad habit or not, but since I had the Dtr’s teething troubles I always ride with my Churchill’s over the clutch, sometimes the brake as well. I have my back brake set so that my foot is comfortably over the pedal…
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!… -
-
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…
47,125 miles today! That’s 34K since I’ve been riding

@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?…

Well, I couldn’t confirm the sizes, so I’m hoping that they’re right so I don’t have to Rip t Piss out of Hotshot!!
I’m just praying that the sleeves are in good enough order (especially the roller bearing one) to match up nicely
…Stopped riding for about six months cause of old git health problems, only just renewed my CBT again!
Took me over a year to fit the new bearings and bushes into the rear suspension linkage! Didn’t realise how big of a faff it was going to be to get them pressed in straight and to the depth that’s needed for the seals! Done though. Nice and tight on the ass end! No more ‘snatchy chain’ feel when pulling awayIs HotShot still around? I need some info on wheel builders in Dorset. I can’t find the old post recommending a particular one. My back wheel is a bit up and down, as well as being a bit side to side…
Unless anyone has a decent straight rear wheel for sale?…
Ta!… -
Oh hey blast from the past!
Yeah @HOTSHOT-III is still knocking about.
Sorry to hear about your health problems, considering how much you use your DT that's a crying shame.

Ta!…@SpookDog Hey bud, hope you're feeling better. I did wonder what had happened to you.
Good to hear you've sorted the rear suspension

Still going well mechanically, just looks like a dog
Cheers for the link bud!…
I really need some hubs if anyone knows of any for sale? Back one is way more urgent than the front!
Only issue is it seems to be running a bit hot. I removed the plastic cover from the radiator and it was an improvement, but not great. I’m wondering if being stood up and hardly ridden since last winter has let the radiator clog up? The radiator was well hot when I checked it. Like it’s not shedding the heat. The ‘fins’ look clear, so I’m wondering if it’s an internal obstruction?
-
It's looking smart with that pipe on it.
The usual suspect for running hot can be the thermostat.
I must admit, DTs always seem to run hot, I tried all sorts (including twin radiators) and the solution for me was to remove the thermostat.
This is really not ideal as the thermostat is an integral part of the engines cooling, it applies pressure to the cylinder head and prevents hot spots from forming.
But I found the DT was just running too hot and would benefit from a lower temperature thermostat (especially if tuned).
But as they say Mr Yamaha know what they're doing and it's a tried and tested machine

@SpookDog Thermostat definitely worth a look as @Calum said. Also the rad could have a blockage, it's not unheard of. I've had some success on cars blocking off the ends, filling them half full of Gunk/Jizer and giving them a good shake before rinsing with a garden hose. I like doing this on the outside of radiators as well, get loads of degreaser in the fins and it's amazing how much crap you can hose out. And I'd still take a look at the fins particulalrly on the back of the rad as they're prone to being folded over by people doing plug changes etc. which can considerably reduce flow through them. It can be quite relaxing to take a thin screwdriver and straighten every single fin and this can make DTRs run a bit cooler.
Also have you taken a look at the waterpump? Being a plastic impeller moulded onto a steel shaft it's possible this could have separated meaning it's no longer making the coolant circulate. TBH I've never known this to happen on the DTR but worth checking on a high mileage bike.
@OllieDTR Has Liam got any wheels for sale? Would be a fairly local solution...
