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.

Because when I try to order parts I get all sorts of conflicting responses. Mine is a DT125R 2002 DE03. The engine says 3BN03. Cylinder diameter is supposedly 56.40 mm for "early models (3DB1)" and 56.00 mm "later models (3RN1 onward). But when I search for those numbers, I get everything from "1988-2001" to "1991-1999" to whatever. Not to mention the differences between the DE03 and others. There does not seem to be any resource online listing the variants with their various idiosyncracies, so this ought to be the proper place to do it. Shall we write up a list and pin it at the top here somewhere?

Well, the Mito engine is highly strung. The Mito runs rings around the DTR, but as a result they're a lot more fragile. I had the same thing with my ETX, absolutely battered bike, but it's in such a low state of tune that the engine was crisp, almost criminal to rebuild it.

Yeah, I used a Honda CR85 Apico one on mine. I though the YZ 125 ones didn't fit.

Hey, im trying to understand the fuss about jet differences between models and years and import etc. I find this very interesting and helps me a lot to fully understand the bike. Like take the same model i would say dtx or dtre with a couple years difference and the jets sizes(also pilot jets) switches significantly and with having the same carb like the tm28ss. Why does it have a difference while running the same engine?

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