There's a lot to this gear jumping business.. its not just down to crucifrom/selector tbh.
However use a genuine or zirri selector only. Use a taffs spring or a mb lambretta spring with a 2.5mm spacer. Shim to 4/5 thou. Check all the drive surfaces of the gears. Make sure shims are not worn. Check for play between the 6204 hub brg and back plate.

If you order from sip make sure with them it is a genuine one. Some I ordered weren't. Part no for a PK selector is 1349026 if you order from a uk supplier. Spring.. well Taffs..ask for uprated smallframe selector spring. You could ask them for the uprated lamb one. (there are actually different types tho.) I use the Mb one with the spacer(you have to make) but they wouldnt sell me any last time as they said "anything under a tenner is not worth our while"  |
