Not sure if this is the correct place to post this? I have a 2000 ST with 75,000 miles on it. It has been hauling around an EZS side car for over 30M miles. I have lubricated the final drive and found no visual damage. On acceleration it sounds like some thing is loose or not connecting properly. Not a great description, sorry. Any thoughts would be appreciated. On my old AirHead BMW,s I had a machinist through Rubber Chicken Racing who would build up the splines and re-machine them to the proper tolerance as OEM parts were not available. I was also wondering if anyone knew of such a service for ST,s as these parts are NA from Honda as far as I can tell. Thanks
