Did any of you guys install the Big bore kit on your Speedmaster? How were the results?

Which one did you do, the 904 or the 988?

Holy moly! There's a 1087 kit? How does this affect reliability of the engine and the cooling? I would imagine that the fins aren't big enough to accommodate an 1100cc engine. What about oil capacity?

Here is some clarification.
1. 904 - cylinders bored and sleeved,(depending on manufacturer)
2. 988 - cylinders bored/sleeved and crank stroked
3. 994 - purchase of new cylinders - cases bored only

4. 1087 - new cylinders, cases bored, crank stroked
5. 1100 - new cylinders, cases bored
6. 1200 - new cylinders, cases bored, crank stroked.

For the more extreme above you will need new rods, bearings, clutch and springs.
