Does My Shee have a +4 mill crank?

[drizzyB]

Hi Im new to the forums but not new to banshees or 2 strokes i have had a few 125 bikes and was into that for a while, but i had gotten a banshee about 3 years ago. So heres some info i got the banshee from a family friend that went threw divorce and was in need of money he had all the receipts for the build beside a few for the motor that he "claims" he done. Im in the process in rebuilding the motor and well im curious if it had a stroker crank so far, in the tear down it has checked out with everything he says. But to the point the crank just barley clears the case wich would be the sign of a stroker crank? The flywheel key is permanently on also and it looks like a super clean job. But if you guys could tell me some more signs of a stroker crank that would be great so i can confirm that its a stroker:) p.s. if any one has some 397/66mm jugs that are g2g let me know

Put a cylinder piston and head on and measure the stroke.

I don't think he wants to split the cases Finch.

There is no need to do that, just measure how far the darn piston moves up or down.

on the top of the piston this is what it says first #s 22203-4, second set is letters wich say WSM Third says S50-520F-6650

I just received new WSM pistons today for my 4mil longrod, and they had a nearly identical info tag.

Mine, which are DEFINITELY longrods say "S50-520 F-5-6550" (6550 being my bore)

 

But you could just have a stock stroke longrod...idk why anyone would do such a thing, but hey.
