1978 gs 1000 e camshaft hold downs

Left hand drill bits work whether or not you know how.

Of course. Use the left hand drill bit first. When the drill breaks through the bottom of the bolt it grabs and spins the bolt out most of the time. If it doesn't, then use the easy out...you just have to have a feel for it.

Shocked you actually got one out. That's happened in a head of mine, the only fix was a machine shop. I kept having bolts break, 4 in total. In the end I threw the head over a large crevas and put a better one on. Only thing I could figure was the alluminum had reached it's age?? as I was using a torque wrench to torque them on and they kept breaking when I tried to take them out. Did this bike actually run? I mean if that cam journal was only held on by one bolt I can't believe there wasn't a TON of noise.

Yeah I picked the bike up 3 weeks ago .andim having to do much more work to itthen i exspected ...I drove it aroundthe neiber hood afew time and once down the main street .. just so I could go through all gears ...
Only 32000 km on it and one owner !! Some older gent that sayshe scared the crap out of himself on the bikeso he parked it!!

You have to disguise it a bit.

Im waiting for your suggestion on how to get this last one out ???

[lrgguy]

Titanium coated drill bit tip is broke in the hole of the broken bolt ....

[tkent02]

Is the broken drill bit still stuck in the hole?

[lrgguy]

Yup down in the hole !!

[tkent02]

Trying to drill around a corner?

A shop 'might' be able to remove it without having to put in a Helicoil.

[lrgguy]

Tried drilling right beside the other hole with a smaller bit , if I use a 3/32 drill bit for the 2 nd hole ill hit the treads ... would a stainless steel drill bit chew up a titanium coated drill bit ? Calling it a night will start fesh tomorrow trying to get this last bolt out !! 2 out of 3 are done ...

[lrgguy]

Couldnt go to bed , cuzz this would just eat at me all nite and tomorrow while at work ...
Using very tiny tweezers I managed to get the broken drill bit out !!
Now I think I will go to bed .. rest up and tackle this last broken bolt tomorrow !!!
I have a difficult time walking away from something thats not finnished .. lol

You and me both! 1 A.M and I just finishing up a little project I've been working on. Couldn't stop until it was finalized.

[lrgguy]

Well I only managed to get 2 of the 3 bolts out , found a guy who will come out to the house and he has all these small grinders etc and will drill out this one bolt from the cylinder head and sais if he cant save the thread he will put in a helicoil .this guy was referred to me from the engine rebuilder in the neiberhood .
All for the low low price of $200

[azr]

YIKES $200??? my local machine shop will do it for $40, that is with the head off the bike of course, but $200?? you could buy all the OEM gaskets to do a top end rebuild for that.
