This tool was submitted to Jims by Hiro Koiso a hands on flat rate technician, experienced engine builder and a JIMS sponsored Bonneville record holder in numerous classes. Hiro came to us with a great flat rate time saver stem nut tool for use on Touring Model Harleys. Normally to get access to the top stem nut you would need to remove the radio package. With this tool you are able to loosen, tighten and torque to spec. the 1-1/2” stem nut without radio removal and ultimately saving you 45 minutes for an experienced mechanic!
