DT125R FORUM

Merry Christmas everyone!

@HOTSHOT-III Hopefully the issue gets resolved as I don't want to lose the data they're hosting. The important stuff I ought to host here to guarantee it isn't lost.

@Rat80y The drain bolt stretching is a common thing on the DTR, IMO it's a design feature as if you overtighten it it usually snaps. Whilst being a right PITA to get the clutch cover off and wind out the broken part, it does mean the thread in the crankcase is saved (new crankcases = much more difficult/expensive than taking off an engine cover) so I hope you've ordered genuine from Fowlers (get a load of copper washers as well for future gearbox oil changes). Tightening torque is 15Nm so it's also well worth getting yourself a 1/4" drive torque wrench like this one: https://planetx.co.uk/products/jobsworth-pro-torque-wrench-set-1 There is some truth in both your AI source and what your friend said. In the days of the 12bhp learner restriction, DTRs with the powervalve pinned shut would struggle to rev beyond 6k rpm but properly set up/derestricted/full power it should rev to around 10k.

Hello all, New owner of a 91 tdr125 lightburner in the USA. They were never sold here and so I’ve had to be pretty crafty finding parts so far since it’s pretty rough! My newest issue is tires. It currently has metzeler Sahara tires on it, 100/90-18 and 130/80-17. Those sizes are pretty hard to find here, especially looking for something with a slightly aggressive look. So far my best options are: Eurogrip trailhound which come in the exact size but are a pretty new tire without a ton of info or long term reviews. Shinko 244 which would have to be ordered in 3.50x18 and 5.10x17 And finally my top choice but the one I’m looking for guidance on, kenda k761 where the main issue is the front only comes in 110/80-18. Has anyone run that size before? Just worried about clearance. I thought tires would be an easy part Thanks!

@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!

After some research I did manage to find the sizes, and some more detailed photos so now I can actually buy some. I do think that it's rather a stopper or something than an adjustment tho obviously it changes the needle height, either way I'm sure they're important. Thank you all for the help!

@Calum That site is known even more year's!!!!!
