Saya bru coba2 modif motor H.Karisma X '04.Yg awalny liat temen pasang knalpot freeflow dmotorny.Jd ikut pasang jg dmotor saya,knalpotny bikinan si ga da merek,cm stelah pasang (tanpa ubah2 karbu),qo top speedny cm 100 y?Tp gigi 3 bs 110.Knalpot standar bs 120(dg susah payah)..Skrg udah ganti pilot jet 38(standarny 35),plus busi champion.Tarikan mkin enteng si,tp top speed msi 105.Kpala busi hitam,knalpot msi nembak2.Rencanany mo gnti seher kaze zone yg 56mm (bore up nich).Ad yg bs ksi saran?Bengkel skitar kmayoran yg paten?
