After originally wanting to just do a carb check/rebuild-i seem to have unearthed problem after problem to my frustration.

After whipping carbs off-found a broken stud bolt (the silly nut on underneath of header pipe that joins to manifold)-so knew that had to be sorted before putting carbs back on after their clean up, but after speaking to a few knowledgeable technicians i was strongly advised to avoid removing header pipe as it has to be perfectly put back together at the copper ring section-so i thought if i remove the manifold from the block i could kill 2 birds with one stone (be able to get to broken stud without removing header pipe) Great!

In theory it should have worked-BUT! after removing 7 of 8 of the manifold bolts (allen wrench type) i come to the 8th and its on sooooooooo damn tight and it didnt seem to have alot of grip inside (sligtly rounded from last it was removed perhaps?) anyway i manged to get a 1/4turn when the allen wrench slipped and just spun-fanbloodytastic!

due to this bolts position-i could not get mole/vice grips on, could not bang in any sockets, could not bang on any sockets-i attempted to bang in a 10mmallen wrench but that was just way too big-so i thought i would cut a slit in the bolt head to try a flathead-did that and that failed, kept trying and trying but bolt was on soooo tight that i ended up just eating the head, so then i was left with no other choice but to remove remaining head of bolt-i originally planned to use a set of easy out stud extractors but i cant get a drill in the space to drill a straight pilot hole!!!!


AHHHHHHHHHHHHHH!!!

any suggestions or tips anyone?

i have exhausted all possibilities in the 10+hrs i have spent on this damn thing!

i am at the point where i am close to just giving the ski away or just smash it up
 
Sounds as though you have whats left, is a piece of all-thread left in the block. With the head of bolt missing, remove the manifold and then either chase the treads so you can install 2-nuts to jam them together to remove the all thread or a vise grip to remove whats left. Undo the pipes bolts that secure it to the casr, one in front of mag cylinder and the other one is located where the pipe cones down, then loosen the wormclamp to you can rotate the pipe up.
