Honda Dio big bore cylinder on a BT 100 case??

[Diggin25]

I found some Honda Dio big bore cylinder heads air and LC cooled . The bore sizes start at 50mm up to 56mm and the bolt pattern dimensions seem to match my BT 100. Has anyone heard about or done Honda Dio cylinder builds on to the BT100 bottom end??
The transfer port shapes are both the half moon style like the cdh 110.
The BT 100 has plenty of engine case to trench out for the much larger cylinder port size.
I'm thinking I need to find another set of BT 100 engine cases and start making things happen.!!!
I'm thinking I can blow all the minarelli builds away with this idea!! Hmm I'm thinking about 80+ mph!!
With a 90 in the future!?!?

What is the stroke for the dio?

I will have to look it up again and write it down ( it's the only way I remember stuff). But I think it said 42mm.

The BT100 is a 40mm stroke, so you might run into issues with that, but if you have the parts and or the money then it's worth a try

Money is definitely at a trickle right now.
A stroker crank would solve that. The cylinders I found have transfer ports more like dirt bikes and snowmobile engines that I used to play with and this is intriguing me!! Do to (old) age restrictions I've had to reduce the size the size of the toys I play with now but this is definitely in my future!!

Assuming it's even actually 40mm. The same engines can come with 38 and 39mm strokes too. There is no consistency with these engines.

It's not for me. So it can't be greed. Just an inconvenient truth.

Ha ha, start with what you got and build down to it.
