I wrongly posted this in performance adding to a thread where I asked about jetting on. so the parts all came in, Estoril pipe fits perfect on the stock cylinder by the way and with the new slot in back it fits perfect in the original hole too. But now that its back together and complete, I fired it up and it's making a horrible racket on the right side basically where the gears are to the sprocket I think. I hope it just means - time to put in all new bearings? What do you folks think?
