I know this might belong in wanted section but maybe I can get some advice before buying. Looking for decent oem trx thumb throttle assembly. Apparently I have a 400ex one and no matter what I can’t get slide open all the way(38mm as). Hangs about 4mm Down. I have new cable and another new cable and now there’s work. Here are a few pics of what I’m dealing with. I crudely moded for more throw but it’s not enough. I also don’t like having a huge throw. Any pointers towards a after market throttle or tips on this. Thanks in advance.
