Neu 1512 pinion fitting issue

[Serum]

With a 65T/18t the distance (heart/heart from motorshaft/strobe) will be 41.5mm. In other words; too large. you need to adapt you motorplate with the 65T to make it work.

Shoot Mike an email, perhaps you can swap the finned Neu for a non finned, like Squee suggested.
