Following the CX500 Cafe and the Hypermotard this engine rebuilt is actually project number 3. The 2.0 in the title stands for the capacity in liters of the M10 engine we are building. We made some good progress on this project. The engine has been completely striped down and we're in the process of refurbishing parts and putting things back together. We've come to learn that the pistons we are using are called "piano top" pistons. Combined with the crank it should give a capacity of 2.0 liters with a higher compression. Because we are using different parts from different engines we will be opting for programmable injection. This will give the flexibility to the fueling we probably need.
As proven with the battery box debacle sometimes things don't go according to plan when you do things "learning by doing". You see the bold in the picture below that hold the hubs of the crank in place?
This is what happens when you over-torque them:
One of the bolds snapped and left a part of the bold in the engine case. Luckily we were able to retract the part of the bold without any damage to the case. We found that I looked up the wrong torque setting in the Haynes manual. Instead of 190Nm the bolds had to be tightened at 60Nm. Oops...
The ports of the cylinder head have been polished and we will grind the valves to give a nice airtight seal.
