First the FW housing must be properly dialed in. This has been discussed many times, and there is a section in tech which explains this. Your gears need to be good gears. You can try good original gears if you can find them.
Usually, most of the internal tranny parts are so worn that everything needs to be replaced anyway. Use only the gears made by the Mark company, which is what most of the suppliers have.
So, with Miles' restored slant, I had dialed in the FW housing myself and did a total overhaul of the tranny (new bearings, new sliders, new cluster, etc etc); so I felt confident this work had been properly done.
Well, so it jumps out of 3rd going downhill ! Now that is not nice.
I borrowed a known 'good' tower and swapped it out, and same thing!
I decided it was time to take a VERY close look at the tower. Hmmmm, it was not as good as I thought.
Third has such a small amount of throw that you need to be sure the parts in the tower are TIGHT, ie, it needs to be ALL THE WAY in gear, else it will jump out.
You need to wiggle everything around and check for wear points.
What I found:
1. the 1/2 " ball at the end of the shifter was good. If not, this can be welded and ground down
2. the 2-3 shift rail had wear at the notches.
3. the 2-3 shift fork was worn where the ball engages
4. The split rivet holding the fork to the rail was sloppy
5. The detent seemed weak
So, I installed a new shift rail, new fork, had bought new plungers, but honestly, the old ones fit the notches better, so I stayed with them. I had bought a new detent spring, but the old one seemed stronger, so I used that, and added a 1/4" ball bearing to stiffen things up more. I used a split pin instead of the rivet, the suppliers have them, I felt it was a tighter install
Test drive: revealed the problem was solved.
Ride safe out there
