Just found loads of fleabay listings that includes the ring with the rubber. Can’t believe that I never saw them before

Put the spare set of new top & bottom bushes in while I was at it. Gonna have to do the bushes in the other fork to match. The 27mm hex drive makes it so easy to dismantle the forks as long as the Allen bolt hasn’t seized to the aluminium fork bottom…I still have a newer set of forks to rebuild with new top& bottom bushes & original seals and progressive springs, but I’m waiting for spring and money to get the new fork bottoms and yokes painted. As well as sourcing the seals for the headstock bearings…
The RH exhaust is an absolute dream. It’s breathing like an athlete with a beautiful exhaust note. Could be a touch quieter for my taste, but I’m an old git now, not a boy racer
it’s just not worth the ‘pull factor’ for me… -

Everyone I seem to see for sale is scraped and dented! I’ve not seen any other second hand dtr exhaust brand that seems to be so similarly afflicted!

PS Callum!:
I know you don’t really ride your bikes to dirtiness, but any tips on cleaning road filth from off of stainless?
I really think I need help cleaning my shit up!….
You really don’t want to see the underside!

Having problems with condensation in the tank from the -0 cold at the moment. I ran it onto reserve on Wednesday night and ended up having to clean the plug and drain the carb bowl about 5-6 times just to get 15 miles, not counting the cut out and roll then bump moments. It’s been down on power since. I need to clean the carb and get another exorcism I think 🥺
If it isn’t one thing it’s another. I kinda wish I was rich enough to buy a running bike -

Whom I kidding? Bringing them back to life is so satisfying, it’s just keeping them running that’s a bitch!

In the last 13 years of ownership it has never let me down and always got me home!
Sure I've had head gasket go on me and one time the ignition was playing up, but no matter how slow it was running it always got me home in all weathers and was used daily.

The other night was the only time it has physically conked out. It still got me where I was going, albeit exhaustingly!…

I’d start with why you have to run it without the thermostat and why it was running at near 100•c (which embarrassingly I thought was normal 🤫 at the time)…Things have settled down for me since I solved the head gasket blowing issue with the pilot jet. The thing is that I’ve done over 20,000 miles while it was missing and popping enough to blow the head gasket, I’m wondering what kind of effect it’s had on the con rod or/and crank?! Maybe why my bike doesn’t like revving up?…
My bike was a basket case when I got it, and one problem hid a multitude of others that I couldn’t see till the previous was fixed…

I'm running a ported Athena 170 kit, with aftermarket radiators and waterless coolant (notorious for raising the temperature). It would benefit from a lower temperature thermostat then it would be grand, but as it is it just takes a while to warm up.

Two strokes are still mysterious to me …I don’t think a lower thermostat wouldn’t solve anything (a working one would if the previous was bust). If the radiator (or 2 in your case?) isn’t dissipating the amount of heat generated in the cylinder, then the coolant temp will keep rising until it reaches the equilibrium that the rad can dispel.
Bigger, tuned engines don’t produce higher temps, just more BTU’s~heat…
Does that make sense?… -

I am running significantly more power than stock probably an extra 50% over the stock power. Plus the bike is a lot heavier than stock with the ally wheels and USDs.
A lower thermostat would definitely help, it's quite common on tuned cars to run lower temp stats to enable the cooling system to function correctly.
Since removing the stat the bike equalises perfectly at 60 degrees, just takes a while to get there.

@ the right temp? It’s 65 iirc, (I learnt from you
) it’s no good if it opens @ 100•cwrote on 2 Feb 2023, 20:18 last edited by SpookDog 2 Mar 2023, 19:20Cleaned out the carb and found bubbles of water still present in the bowl and around the main jet. Power is back to ‘normal’ though it still doesn’t want to rev freely up to and beyond 7K. I’ve got a few plans forming in mind, including swapping out another CDI I gotten (wish the original fitted had markings!) unplugging and ‘pinning’ the power valve to see if there’s a difference…
I’m really not sure about the crank after 20,000 miles of riding while missing at low throttle. The bearings are ok but that doesn’t mean that the Conrod is true…
I do have another good crank and casings, ect that I’ve been planning on building a ‘new’ bottom end lump. I just need to be able to focus on it without other problems stacking up 🫠
Remember to check the power valve servo closer, it appears to be opening at 7000 . But could be higher…

So it would fluctuate around 80-85. But one day I made it literally a mile after leaving home and it went to 110. So I turned back and removed it and its been perfect ever since. Just takes a while to warm up.

Definitely sounds like the stat failed to me, especially if removing it solved the problem. I’ve got a couple known good spares if you want to try one before paying out for something you think might not work…
Is your temp probe on the head or radiator or?

@SpookDog I have a few thermostats lying around. As I say I tested it in the stove and it opens and closes fine, but don't know the temperature.
The temperature is measured at the head with a digital read out.

Best (I recon!) way to do it is in a pan of water gently/gradually brought up to temp with a thermometer in the water right next to the thermostat (suspended in the water with wire)…

A random tapping/knocking noise has appeared during tick over since removing the oil pump/replacing clutch side main seal. Or since water in carb cut out episode…
Also fit rubber mounts and P clip mount to exhaust…
PS remember to turn off the lights when adjusting the carb, the drag caused by them is significant…
PPS didn’t remove the oil pump!!
Piston was a tight good fit when assembled. Am getting Tappety sound at TDC when turning flywheel by hand. Will check more through the exhaust outlet when pipes off for rubber mounting…
