Crankshaft $1449

Crankshaft
Pistons, wrist pin bearings and seals not
included.
The 4340 forged crankshaft weighs in at 7.8kg and gives the
motor an 82mm stroke while being assembled using
NSK C3 bearings.
Our rods are 144mm long giving our engine an ideal rod to
stroke ratio of 1.76. All pins and surfaces are nitrate treated
for increased longevity. Fits 20mm Flywheels. If you're rebuilding an entire
engine please remember to get crankshaft seals as well.
Installation notes: Test your rod clearance on the new crank in the
case before sealing it up. Some rods will come into contact with
the case on the exhause side as the piston rotates to top dead center.
The case can easily be clearanced with a dremmel if needed. If you
purchase a crankshaft from us we can provide a video if needed.
Grease seals prior to installation. Allow case sealant time to dry
before use.

controller.

Piston to Bore Clearance
. This is the approximate breakdown. It's important to know that we
had variations during the production of these engines and the hone
were often tweaked (±0.025mm or so) to suit supplied pistons.
997 Carb (CDI) = 0.125mm (0.005")
Piston Skirt = 87.925
Bore Hone = 88.050
997 Carb (Smart Coil) = 0.150mm (0.006")
Piston Skirt = 87.925
Bore Hone = 88.075
1162 Carb = 0.175mm (0.007"):
Piston Skirt = 94.950
Bore Hone = 95.125
1162 Port Injection = 0.200mm (0.008"):
Piston Skirt = 94.950
Bore Hone = 95.150 |
