Greyhead, I forgot what your problem is. A knock? If so, lets talk about it. Chances are the solution is a matter of tuning & adjusting, not gutting & replacing. You need to know what the problem is before you decide if its gonna be you fixing it or you paying someone. If you dont know what it is before you hand it to a mechanic, you have no assurance that the 10 hours at $65.00/ hr charged to go in & replace a bearing is really what happened, or if they tightened the peg bolts & just SAID they changed a bearing..
