Pulled the engine down today and found more excellent quality! It has the huge intake flange, same size as a 66cc exhaust but with an even bigger port! This thing is gonna SCREAM!
The rod feels nice and tight on both ends and the pin is unmarked, as is the piston and cylinder. Top end is totally useable and in great shape.
Now for the BAD news...
The mains are wasted. Binding and crunchy bearings mean I have to split the cases.
I'm hoping it has the same size mains as the 66cc so I won't have to wait for a set of bearings...
Anyone out there know if the 49 has the same mains as the 66?
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
