glider you are correct about the screw or bolt. my problem is all the Harley Davidson dealers I've called or went to tell me they don't sell that screw or bolt, they want to sell me a new throttle body for $ 500.00 and that ain't going to happen. I went to King Bolt over in West Covina and bought some screws that looked like they fit both in standard and metric, they seem to be the correct size but the threads are different. what I'm trying to find out is what isn the correct screw size? I've been told to retap the hole with a bolt that will fit, but I want to see if I can find the correct bold before I retap the hole.
