Last year I made a 1-2-1 shift with my dog ring box that cost me some racetime and money   Wink
Now I want a firstgear blocking device
Has anybody here made one or got some photos or idea to make one ?

Thanks John

Maybe there is a way to modify the reverse gear blocker in the shifter so the button also must be used for first gear?

Karpiola/SF gears supply a "dooverlackie" that stops your issue.
It is mounted under the nose cone by a bolt
and pivots on the bolt as the hockey stick sweeps through its arc.

It is called the "pox preventer part". (true story!)
Give Jussi a call and ask for one.

The one that came with my gear set, came with NO INSTRUCTIONS,
so may take some ingenuity to fit.
