Jetting the carb
-
Hey, guys im new.
I just got a yamaha dt125x from 2006, with a custom exhaust from romeu Henriquez. My question is wich jets i should buy for this exhaust? The bike is stock except i changed the reed valves to carbon ones en putted a spacer on the intake. Hope you guys can help me out

Unless required, I'd leave the jetting alone.
Even DEP recommend just leaving the jetting alone.
Once you get the pipe, warm the bike up and do a plug chop. If it's hesitant, bogging or the plug is not golden brown, then consider a rejet.
If you're running the stock DTX carb, then 210 is the stock jet. The earlier models came with 240 main jet.

@calum thanks for your reply. Stock jets are indeed present, main is 210 en idle is 17.5. my carb is a mikuni tm28ss. Bike bas bogging(buuhhh sound) if i twisted the throttle while idling when it was warm
@Elan-n Have you done a full carb clean including the emulsion tube?
-
@calum @hotshot-iii yes i did a full carb clean, took everything apart and cleaned it and i dont know, the seller told me it drives good and gave the original exhaust with the bike too. I also ordered an fully overhauled carb to replace it. Came in today and dontacted the seller from the exhaust and told me to use a 245 jet but havent tried it yet. Tomorrow im gonna install everything back
