    I found out that the shorter rear axle collar(part numper 90387-202U8) is the same on the Wr200 and Dt. If anyone has that longer collar(part numper 90387-206X8), could you measure its length? And if anyone has a wr200 rear axle, could you measure its length? The rear axle part numbers of the Wr and Dt are almost the same WR axle part numper 3XP-25381-00 DT axle part numper 3BN-25381-00

    That's normal. All DTs are like that. [image: IMG-20251011-114625.jpg]

    Well it looks like I have found the issue... somewhere along the line someone has pikey bodged the front axle and spacers... What should have had the sleeve spacer which has the 1mm wall which slides in to the 17mm ID bearing was clearly lost and someone had inserted a 40mm x 15mm bearing and used a spacer from an older DT in place of the correct one.. The joys of owning an unknown modified bike! So I am now getting a spacer machined up and I should be good to go! It has only been holding me up since before christmas.. so now I can get the wheels fitted, get the bike back to mine and do the final few bits before MOT.. starting to get excited now Picture of the spacer that I should have had below: [image: 1773302928622-spacer.jpg] Versus the spacer that someone had installed and was somehow using..

    @Kristóf said in POS mode on switch: So does this mean that with the main switch to ON and the lights switch to POS it should light up the auxiliary light even with the engine off? No, lights switch to POS with the main switch to ON only illuminates the auxiliary light/tail light with the engine running because with the switches in these positions, the auxiliary and tail light receive an AC feed from the stator via the yellow/red wire. @Kristóf said in POS mode on switch: I'm asking this because my auxiliary light works when the main switch is to PARK but it doesn't work with the lights switch to POS Yes, this is because with the main switch in the PARK position, the auxiliary and tail lights receive a DC feed directly from the battery via the red wire (which connects to blue/red at the main switch in PARK). It took me a long time to fully understand this so glad I'm able to explain it properly!

    Yeah that sounds like a good idea and should be easy to swap the wheels over without too much faff!

    Not familiar with a 1994 DT175 (I presume this is from the Asia (Far East) market). The oil light will just be for the two stroke. There are no sensors that do gearbox, the most you get is a Neutral Light sensor (if you're lucky). For the gearbox oil, the only sensors you see are with your eye balls and the oil sight glass. I can't 100% say this is the case, but I say it with high confidence that this will be the case. Hopefully that's useful. Calum

    @CYBER-NINJA An ally rad would make a huge difference. The Lanza rad, like the DT200R Rad, has a tiny capacity. I'm sure it ran very hot. But then the DT never had a digital temperature gauge to compare it to. The RE's Simply have a light that goes on when the engine is too hot.

    Most 4 stroke bikes use the same oil for engine and gearbox, so any bike oil will be fine. But car oil is a no no as it has additives in that will make the clutch slip.

    @Darty I am not convinced a bit of water would have seized tge engine. Any good engine builder liberally coata a freshly built engine with lots of oil. Although now I think about it. If the leak was at the bottom gasket, and was severe. Then haven't you juat hydrolocked the engine? Clearly it neess investigating so until you split the cases you won't truly know the extent of the damage.

    Alright, that's a no to the higher pitch in that case. Doesn't look like I'm going to get any of this stuff before the weekend now. I have a whole heap of new stuff that I'm dying to get on the bike, so the drivetrain stuff is going to have to wait I think. If I can get the bike running this weekend I'll place an order for one of those anodised renthal rear sprockets, a 428 chain and a standard front sprocket. I'll probably come back and ask about chains then. Here's hoping I can get a spark this weekend.

    @Uber_Beluga So if you have four wires - one will be an ign. Switched live to the starter switch. One will be the return wire to the starter solenoid. Then the other two will be a feed up from the CDI and a return that either goes back to the CDI to make a circuit or maybe goes to earth as I mentioned before. Just buzz the wires out with your meter to check what they do, but if you can get a good make/break across the switch then that's not you problem.

    Clutch needs to be balanced properly if it's dismantled. But But noise is generic. Is it metal on metal sound?

    @Leftyno1 yeah nice one man. Yes and no. Of course when the clutch wears significantly it will slip. But it will not disengaged before it slips so theres that. What I mean is when the clutch is on ots way out. With the clutch lever pulled in the clutch with not disengage and still pass power to the wheels. You them adjust it to its max setting on yhe lever, perch and clutch drum. If that still fails then new plates amd springs. But I mean you would need serious mileage before that happens. By which time you will do a full engine rebuild and why you wouldn't build yhe clutxh at that stage is madness.
