    im going to remove the engine, blast & paint the frame, and reassemble to the point where I can try and start it. tank/carbs/coils etc..and go from there, got to drill & tap the head for the two new exhaust bolts. Im quite optimistic that it will run, that's the only thing the seller assured me, that it was a very good runner, well tuned.

    Had to get a broken off bolt out for a friend today, so thought I would take some pictures of how the left hand drills work. Note the different twist.
    001.JPG
    Bolt in Suzuki chain adjuster had been bent ( a common problem with this style adjuster), so cut off neatly with hacksaw.
    002.JPG
    Drilled a 2mm hole about 10mm deep.
    003.JPG
    Using the left hand 5mm drill was able to get it to 'grab' the broken bit and wind it out.
    004.JPG
    Sorted.

    Has anyone had a chance to try those Grabit drill out tools? I have always used Easy Outs in the past but they look like they might be OK?

    You have seen the state of my corrosion, where both materials have literally welded together, personally, I think the only way is to drill and tap, but I'm willing to try new things. I have a good quality set of easy outs on the way, and I may invest in some LH drill bits. Cheers for the tips.

    One more tip then, if you break an ezy-out off the best way I have found to burn it out is with a plasma cutter.
    My mate bought a Honda CRF with a broken ezy-out in the adjuster bolt of the alloy swing arm, and careful use of the plasma got the bolt melted out without damaging the alloy.

    Other option is a carbide drill to get snapped ezy out or drill

    OK, I pulled the RGV shock out today and as suspected, it's dimensions are identical to the GJ73a :) Shock length eye-to-eye is 310mm.
    WP_001728.jpg
    Top shock is GJ73a, middle is RGV, bottom is the WP unit I'm putting in mine. This is requiring a bit of cutting and griding to fit in my 73. If there is room around the top of the shock for a piggyback reservoir an 03-06 CBR600RR shock is a straight bolt in.

    Been at it again today, removing broken bolts from various bracketery. There no such things as 'easy outs' blummin rubbish! I started on the thermostat housing, as I could drill right through, giving me half a chance if the easy-out snapped.....and it did. As I had access to the rear of the hole, I fashioned a masonry nail and tapped the broken easy out tool from behind. Thank goodness i had the sense to drill right through.

    one hole was good (M6 1.0) the other hole's thread was erm....not good, so I tapped it out to M7.all is well....still not sure how the broken alloy around exhaust apertures is going to perform.....it will either be gas tight....or not. there's not a lot I can do about it with virtually zero budget. I have some chemical Metal, I have used it before, just not around areas where there are extremes of heat. Any advice chaps?

    Aaagh I hate those tapered easy-outs. They expand the bolt as you try to remove it. Completely stupid design.
    Use heat, Murdo's left hand drills and Ridgid screw extractors. A small propane torch will do wonders. Aluminium expands very quickly and the steel bolts will not.
