Nice test drive just, lots of gearchanges, esp 1st -2nd-3rd-2nd-3rd-2nd etc etc and all is much neater.
Have clean reverse selection and 5th to 3rd and 4th, so overall all is well.
Might be nice to have a weaker sping bias on 3rd/4th, but need to see if you need weaker springs.
iirc some came with the shifter, but goodness knows where they are now.

However, well worth the effort! :drunken:

Checked on the Rennshift site, and you can change the spring bias readily, so will soften the gate bias from 3/4 across to 1/2 so easing the down shift further, but will keep the 3/4 across to 5/R as it is.
There is a spacer under the soring that will need a touch on the lathe and it's done.

Nice to tweak this lot and get things more useable.
