Crankshaft stroker +6

[loictahiti]

Hi guys
I have one almost brand new crank +6 old school design ( oem rod size) with crankcase trenched and reinforced .
Just asking what is the best way to use this crankshaft?
- oem cylinder + spacer,
- aftermarket +6 cylinder ( and which one)
- or other option

Thanks

What rod? doubt it’s got a 125mm stock length SJ rod. Maybe a 133 stock kaw length rod?
Old school was 133 Suzuki or Kawasaki rods

The connecting rods are offset on the crankshaft then welded and balanced

I typically had my domes cut to accommodate the travel above the cyl deck. Worked well for me on my 5mm.
What kind of riding are you planning on doing?

Your transfer timing will be so high with a 61x 62t cylinder and that crank as described. Plan on sticking the piston out of the hole some to gain some back. There was a reason the industry walked away from 5mm/125 rod cranks in about 94/95. They were the limit on rod ratio and 6m6 650 cylinders bored to 81mm.
