Hi all,

I have been lucky enough to be the new owner of an 96 XRV750. As we all know there are not many here in the US and I'm excited to get her on the road. I'm working on rebuilding the motor and I can not find info on what grit of hone to use to re-ring. I have factory rings and the bores are great just need to knock off the glaze.

As a bike mechanic I make a great train driver and electrician so when I honed the barrels of my Hyoo250 a couple of years ago, I went to my favourite auto parts store and bought the one small enough to fit those little barrels. I've no idea of the grit measure, but it seems to have worked as it is still oil tight 5000km (3000mi) later.

Lee, I remember when you did work on your rd03 engine, was it just new rings and honing? Did oil consumption go down?
I put new valve seals too. But yeah, oil consumption was higher than normal during my North Africa trip. Bu I would attribute it mainly to dry valve seals. Not to mention that the motor had 125,000km ;-)

If it's just glaze-busting that's needed, then some fine (1200 or more) wet'n'dry/emery used gently with oil should do the trick .... no need for specialist tools.

Terrible things i wouldn't use that on a bean can ... what you need is this

https://www.amazon.co.uk/70mm-Flex-Hone-Cylinder-Silicon-Carbide/dp/B002XUL0RW/ref=asc_df_B002XUL0RW/?tag=googshopuk-21&linkCode=df0&h

and yes there not cheep but nor is tearing a motor down after the rings wont bed in ... a ball hone they come in different sizes .... if your stripping the motor get the honing done in a Sunnen machine and go for a high hone and make sure the person knows what there doing ...
