W/o even attempting the math, I am pretty sure if you did it, you would have less than 70cc. Probably would make just as much torque as hp if you did it though. Try it and tell us how it works out for you.

If anyone knows, what is the length of the stock 50 rod and what is the length of the stroker rod?

I am thinking it's a 65 thor, that's why I said less than 70. I didn't want someone to jump in and say I was wrong.

I normally go by this. But, it doesn't go down to 39mm bore.

Okay fellas. Put this in your favorites.

A xr70 piston and 51mm crank would give you 88cc glen.

It might be work but sometimes it's fun to dabble a bit.
