Kliff is right, the proper tools are a must as well as know how. When boring the case it is easy to bore off center or pennitrate the oil galley if you don't know what your doing. So many try the cheap route to avoid paying the price of boring a case only to be dissapointed when engine failure accures. The actual boring process does not take that long, its the setup that takes time and this is what you pay for. If not set up precicely you end up with a trashed case. The bore must be centered with the proper clearance between the case and cylinder to compensate for expansion due to the 2 dissimular metals which have differant expansion rates. TOM
