I snapped off my heads exhaust studs today
Posted: Sun Jul 29, 2007 3:47 pm
Getting my old 90k winter bike ready today I could hear the exhaust blowing a bit, found one stud completely gone, just a hole.
Even with care 4 out of the 5 remaining studs then broke off. Some were wasted away so bad a 11mm socket had to be hammered on.
Two on the left head had been attacked long ago by a previous owner; a sorry sight, old breaking out casting around them, drilled and tapped in situ and on the skew.
A couple of urgent questions;
Those socket type stud extractors, is there room between fins to get them in, or do I just dremmel them flush and re drill 'em?
Also I hear I should get a Time-Sert instead of Helicoil?
Any preferences? What's the life of either in the harsh exhaust location? How long have you had yours in?
Any tricks or tips to patch up the old girl welcome.
