Hi has any one every helicoiled an atc 70? if so was it hard at all? Just want to see if I am going to have problems before I start.

P.S.- The helicoil part for the atc 70 is hard to find, so if you need one, here it is:
Helicoil

 

Where are you installing the helicoil?

 

the spark plug hole

 

Just make sure you use red loctite or it could come out with the plug when you change them.

 

ok thanks

 

Also make sure to check that the plug depth is the same as stock or you could run into problems. If too deep your piston could hot it or if not deep enough it would run crappy. I've seen both senerios personally [img]i/expressions/face-icon-small-smile.gif[/img] and they will drive you crazy trying to figure out why it is not running right.
