So you think would be best to just go back with the orig.? 4 wouldnt make that much dif.? Would i be able to tell much dif. going from 6 to stock? I have ran the 6 for prob. 50K. But said seems to lag on hills and may be getting noisier or my imagination. One reason my son was here when I started it up. He said that seems like alot of noise from engine. Got me wondering with 100K now.
100k you may need new timing belts and check the bearings in the tensioners. I had one go out with only 14k on it. The tensioners can be easily rebuilt using a car idler pulley for around $25 verses $80 each. I did one where I posted pictures on this site as well as do the google. It will pull up the goldwing article that I used.
