The DRILLSTARTER fits many pit bike engines. The important thing is the thread in the flywheel. This must be M27x1 LH. If this is the case, then only the alternator cover needs to be drilled. For most engines, it is sufficient to place a hole with a diameter of 30mm in the middle. Alternator covers are available in the shop that are already prepared.
On the Zongshen 190, the edge on the inside of the hole must be removed (the hole is present from the factory).
The DRILLSTARTER is not compatible with Zongshen 190 with E-Start (or E-Start flywheel).
