It broke off right at the bottom of the thread so there is about a half inch of unthreaded bolt sticking out of the block.QUOTE]
peanuts.
First, take a hammer and rap the stud a few times on the end. This will shock the stud and possibly loosen it. Then, slip a nut over the end of the stud and weld it to the stud. Take a wrench on the nut and unscrew the stud. If it won't come out, heat the head around the stud with a torch. It is a standard right-handed thread. If it unscrews from the head, the threads in the head should be ok.
uh_oh said:its threaded is there still part of it sticking out? if so take a pair of vice grips and pull it out, you can replace it with a regular bolt.
good luck :nod:
I did the same thing on mine, it worked perfectly.Ol'89r said:Vice grips usually wont do any good on an exhaust stud. They normally need to have a nut welded on solid and heat to remove them. Why would he want to replace the stud with a regular bolt? :coocoo: The factory uses a stud for that application for a reason.
It's best to use OEM hardware for your bike.
So because it worked for you it is the official fix? :laugh: Let's look at the big picture here. Honda employs some pretty smart people to come up with their designs and so they should be significantly more qualified to select a fastener appplication than somebody with a pair of vice grips and some luck. I'll take a stab and suggest the reason they use a stud instead of a bolt might have more than one answer. First different materials so there is a good chance the steel fastener will corrode in the aluminum head, yeah just exactly like what happened to both of you. Now let's look at the other possible reason. Aluminum is softer than steel and so the threads are more prone to getting all screwed up (technical term) not to mention worn and loose so the torque value would not be correct if you remove and install the header a few times.uh_oh said:I did the same thing on mine, it worked perfectly.
and what would that reason be?
Im not trying to be disrespectful to him, im just saying I replaced it with a bolt after I broke mine and I havent had any ill side effects caused by it.Patman said:So because it worked for you it is the official fix? :laugh: Let's look at the big picture here.

Reason three would have me pointing out that 89'er has for sure forgot more than you and I put together know about bikes.
