Head gasket sealing?

When you say honing the cylinders are you using an actual honing tool or a glaze buster type. If it's a glaze buster be very careful as to how you use it remember these are quite close tolerances that are used. Also keeping the thing straight can cause issues. I know they are supposed to self centre but as I say be careful, use a slow speed on the drill and work it up and down the bore to get the cross hatch. If you have an old set of barrels try a practice first on them.

Hi neilg, yep it's the deglaze type. Good idea on the barrels. I haven't got any knocking about but if someone wants me to practice on theirs I'm more than happy to give it a go. Thanks dude.

Just to explain my thoughts, I tried one on a Kawasaki Z250 I was building. Although I had it set on the smallest bore setting it was still tight so the springs were loaded. As I pulled the trigger the whole lot was sent spinning in my panic I pulled the tool out and of course my finger was still on the trigger so it went faster and exploded into pieces when it emerged from the bore and sprung open as it spun, (I'm actually laughing as I type and remember this). I've never tried it again and the last time I deglazed bores was on an old Bonneville, (a real one not the latest pretend model). I did that by hand and with fine emery cloth though they are a bit more solid and  not as precise as Hondas. I have considered a second attempt but if I did I would have some one hold the block on its side or clamp it in a vice this time. Remember the stones should be allowed to emerge from the bottom partly and not stop at the bottom as it would if you had it stood on it's base. And use plenty of oil to lubricate things. I think the issue is that these tools are really made for larger bores such as cars and not bikes, as I say even set on its smallest setting by the time it was squeezed into the small bike size bore there was quite a bit of tension on the springs.
Love to hear other peoples experiences wit these.

Just to deglaze is easier with a flap wheel
