The engine is noticeably quieter, especially at an idle. There is still some of that noise at the 2500-3000 rpm range, but it is also noticeably quieter. I had an annoying "tick" at idle at nearly any temperature, and so far that is gone. My front exhaust shaft was very loose and I think it was clicking back and forth as there were witness marks on the bolt. I guess time will tell as to how effective this mod/upgrade was. I intend to rebuild this engine before this time next year, possibly to 120ci and I will be installing these again on that rebuilt engine.. ! Thanks for your work. Glen

For testing purposes, I tried them both ways. Going in one way only allowed it to go in a tiny amount.. the other allowed it to go almost 60% in by hand. But as I said, you can clearly see the taper...but that was a good question..I rode into work this morning.. beautiful day here in central Ohio!! Glen

However we only received four of the inserts, not five like shown in the pictures so we could not finish the rear arms/shafts. We ordered another set from Amazon. Hoping this one comes with five inserts so we can use the extra on the RK and use the other four on another bike. Haven't got the rear done so we haven't been able start it up and see if it is quieter.

Quality control Rockout! Every package should come with the extra insert as shown in the pictures in case a mistake is made. New set should be here tomorrow or Wednesday.
