Developed by one of our good customers we are manufacturing the new Z4 Starter hub to replace the stock 2 prong starter drive in the Zenoah and similar engines start assembly.

One of the biggest problems we are faced with when starting our engines, especially the high compression is when the pull starter is jerked the hub has to travel and slam against the starter drive, it tends to wear the nylon start hub out quickly.

The Z4 features four prongs instead of the standard two, this configuration enables the starter hub to catch extremely fast lessening the chances of it stripping out. Prior to manufacturing we tested it on our high compression M6 and it worked as flawless as we were told showing hardly a hint of wear on the nylon start hub. This product is highly recommended for all G260's, RCMK's, and clones using similar starting components.
