I donāt think that it is. Thereās no play on the lever, let alone sponginess, but I donāt think itās getting the full pressure of the system at the pads. I canāt see any other reasonā¦

@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 donāt want to take the bike off of the road though. Also Iāll 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 ācagesā were drift~fitted inside the linkage to frame union. They were very thin gauge metal and easily damagedā¦
Ta!ā¦
PS. Is the 20mm inner or outer?ā¦
Edit: The inner is 20mm on both bearings and bushes. Are the bearings 23mm outer like the bushes?ā¦

Well, I couldnāt confirm the sizes, so Iām hoping that theyāre right so I donāt have to Rip t Piss out of Hotshot!! š
Iām just praying that the sleeves are in good enough order (especially the roller bearing one) to match up nicely š¤ ā¦ -

Took me over a year to fit the new bearings and bushes into the rear suspension linkage! Didnāt realise how big of a faff it was going to be to get them pressed in straight and to the depth thatās needed for the seals! Done though. Nice and tight on the ass end! No more āsnatchy chainā feel when pulling away šIs HotShot still around? I need some info on wheel builders in Dorset. I canāt 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 sideā¦
Unless anyone has a decent straight rear wheel for sale?ā¦
Ta!ā¦ -
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!ā¦@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 :+1:

Still going well mechanically, just looks like a dog š¾
Cheers for the link bud!ā¦
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. Iām 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 itās not shedding the heat. The āfinsā look clear, so Iām wondering if itās 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 :heart:

@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...

Cheers guys!...
I've got a half decent rad i bought a while back. alot better than the used stuff you normally see on fleabay. i'm gonna flush that and leak test it, as well as checking for decent flowrate. Ill order a new thermostat and do them both together...
Has anyone looked at the replacement rads on fleabay? there's a chinese one for Ā£90 and a chek one for Ā£114. i'm leaning towards the chinese one just because the quality of the TIG weld looks to a much better standard.
-
I've never had any luck with the Chinese ones
winner racing. I say that but the ones I bought for my ETX were from them and they actually fit, sort of.But I have bought numerous previous one to no avail.
Itās a shame that theyāre shite, because I think the radiator is the main problem. If it was the thermostat Iād of thought that it would overheat from the start, but it keeps cool enough for a while depending on how hot it is and how slow Iām going (less air flow over the radiator). The radiator is well hot to the touch!
Iām waiting on a new stat and gasket from PJME and Iām going to flush the radiator thatās on the bike with a hose in the meantime. The fins on the back are better than my other radiator, which is originally pristine in every way apart from the rear fins being the worst Iāve personally seen

Any decent fan kits to mount to the radiator? Adjustable thermo activated switch, shrouded to pull air through from the rear of the radiator?ā¦
Iāve got some work to do first, there was oil scum in the radiator and I guess all the way through the thermostat, pump and system. (Iām wondering if the stat is all gummed up) The pump rotor and seals were replaced when I rebuilt the bottom endā¦
Itās not the head gasket blowing though, itās not pushing coolant into the expansion tank or noticeably lowering the level in the radiator.
I had problems with a slight step in the casings at the rear of the barrel which I thought I had fixed. Thereās a āwet lineā between the barrel and inlet manifold that seems to support my theory.Iām waiting on a new genuine base gasket, thermostat and some Loctite VHT copper RTV sealant, as well as the thermostat and gasketā¦

fitted the new base gasket, the old one was soggy and leaking under the exhaust manifold into the barrel. Still pushing out white smoke! i went back on some of my threads from 18 months ago when i built the bottom end and found out that i'd used hermatite red instead of silicone RTV to seal the crank casings. I think it's failedwhere the coolant flows from the barrel to the block.
I'm gonna have to split the casings and use proper RTV...
At least i kno2w why it was running hot. Also learned not to use mismatched casings. Mr Yamaha obviously used different castings for various iterations... -
