There are days when you just shouldn't tinker... I read in the MZ forum that other MZ riders with a similar setup have installed a 125cc HD (and larger). Why does my "Rusty Bertha" over-enrich with the 125cc, and why do I have to de-energize significantly? Is the air filter to blame??? https://mz-forum.com/viewtopic.php?f=...
