how do you make the trx 90 thumb throttle work with the exeisting throttle cable, or can you? i bought a thumb throttle and it seems the cable is a little to long to work. seems like there is a little to much play.
You wanna get the trx 400 or 450r throttle assembly to match it. Then remove the spring inside. Then replace the TB spring with the BNR lightweight spring. Good ol servicing or replacing the throttle cable and 👌🏿
