Malossi engine cases are the first choice for building a powerful and reliable engine for Vespa Largeframe models.
The engine case offered here features the extra sturdy King shaft with 65mm stroke and 128mm Primatist connecting rod.

The longer connecting rod (+2mm) allows you to set the cylinder's steering angle to suit your engine design without having to turn off the cylinder.
In addition, the longer connecting rod improves the connecting rod ratio, which is important for the smooth running of the engine.

This crankshaft is perfect for Quattrini M232/M244 and similar cylinders. Cylinders.

Crankcase diameter
If a crankshaft from Kingwelle with extra long stroke (up to 65mm instead of 57mm series) is used, it is necessary to increase the diameter of the crankcase to be able to mount the crankshafts with their larger cheek diameter. This is already done by Kingwelle on the case offered here.

LIGHT MACHINE SIDE BEARING SEAT
In the same step, the bearingseat of the light machine side bearing is reworked. Malossi was a bit too good with the undersize for the bearing fit. 7/100mm undersize usually leads to a very tight running bearing. Kingwelle reduces the undersize to 0.040-0.045mm. This has also been done on the motor housing offered here.

RECOMMENDATION NU205 C3
An additional recommendation is to use a two-piece roller bearing of the NU205 type with bearing clearance C3. This makes the assembly of the engine halves much more comfortable than with the one-piece ball bearing supplied by Malossi. Kingwelle expressly recommends the use of such a bearing type (see accessories).

CONCLUSION
The most professional solution for high displacement HighEnd engines with Quattrini M232/M244 and similar. cylinders. Anyone aiming for performance well above 40hp will find the perfect basis here.
