I have another question
Ever since my bike came back from the mechanic a few years ago, it has had very poor low-end power and it never felt the same again. His excuse was that the bigger piston is heavier, but honestly I’m not convinced.
My DTX is noticeably slower than my friends’ DTRs/DTRE, especially in low RPMs. To be honest, I never went back to that mechanic after that. I already adjusted the YPVS before, but the problem still persisted. I also cleaned the carburetor and installed a new spark plug.
Right now I’m waiting for the new CDI to arrive so I can properly tune the power valve again and see if that changes anything.
Has anyone experienced something similar? Could the bad CDI cause such a big loss in low-end power?
Current setup:
Firebox expansion chamber
Firebox silencer (I think)
Original carburetor
18T front sprocket
51T rear sprocket
