Yamaha Dt125 float height
-
Hello,
I'm no Tik Tok guy but this folk seems to explain a way to know how to adjust it in a cabruetor from an early model DT, dont know if it will help much, but its the best I could find out there.
(I recomend you to read it in subtitles since the guy is talking in Latin Spanish)

@HOTSHOT-III I was waiting to get home to grab my Haynes, so thanks for chiming in.

@HOTSHOT-III do you know if this carb has a air jet, because my bike is runing lean on pilot, no matter what pilot jet i put.
There is no air jet on intake side of a carb, shouldthere be one?
Thank for answer for float height -
@Camugica No worries
The DT125R TM28SS uses a mixture screw instead of an air jet, it's the brass one on the left of the carb body just in front of the carb-to-airbox rubber (below the idle screw). Normal starting point with a healthy engine is around 1.5 turns out from fully screwed in. Screw it in further to richen the low-speed mixture or unscrew it more to make it leaner. There should also be a spring, washer and O-ring on the screw (in this order) so it's well worth checking this if you're having low-rpm running problems. The screw is prone to seizing on the DTR carb so whilst it's removed smear some copper grease on the threads.
Some other Yamahas use the TM28SS with an air jet instead of a mixture screw like the TZR/TDR250 and DT200R 3ET (I think).
