Hi all, I recently bought my first bike, a '71 CL350. The bike came with a spare (read "seized") engine. The good engine has a loose fit for the left spark plug, and I'm hoping that I can route out the second engine's threads to use it. In the case that the second engine's threads are shot too, does anyone have suggestions for a helicoil kit? And yes I have already run a die through to make sure threading is clean. Thanks in advance and look for CL350 engine parts in the selling forum as soon as I get my good motor running.
