GRRRR!



I just received my ATC70 head for my Z50a frankenbike after waiting 2 weeks for it to be shipped from the East Coast to Ontario ($25 shipping!).



Guess what? Spark plug hole is stripped, somebody shoved a helicoil in it (not installed, shoved!), there's corrosion on the cam shafts' journals and the the rhs cam cover has 3 broken fins!



The item description says came from good running unit... BS! All the nitrous in the world wouldn't help that head create compression!. Not only is the plug hole now oversize (M11 x 1.00?) to allow for the helicoil, the flange surface for the plug gasket is galled and concave due to stupidity.



The seller claims ignorance (whaddya mean heli coil? You know, the sharp thing that stabbed your fingers when you tried to install a spark plug on a crazy angle?). After reviewing his record, I see he's been buying and selling bike parts on fleabay for some time, with a 100% record (up till now).



:confused:



After doing some reading I see a few of you have installed Timeserts or Threadserts. I thought about doing this myself but the kits are like $90, the local machine shop wants $50, and it's doubtful they'll be able to pull it off (oversize threads). What was your experience?

I think all the negative feedback gets deleted after a year. I had one burn to my name (of my fault, of course) and my feedback is at 100% now.



Mind posting the link?

As an FYI the easiest repair and the cheapest repair is to drill and tap it out to 12mm. You can readily get spark plugs with the same reach in 12mm. As a matter of fact, I purchased a head from someone on this forum that the threads were stripped and it was not that big of a deal. Took about 5 minutes to repair doing it that way.

I believe there is enough room to thread the 12mm plug all the way in and not have the valves hit the plug tip. The DR8HS plug has the same 1/2" reach as the CR7HSA plug.
