I have a Sirio .18 drop in for a Maxx. The problem I'm having is the guy who had it before me cut the pilot off the shaft!! (why..I have no idea ) The problem is I haven't been able to find a pilot shaft adapter to fit.

The threaded part of the crank is the same as a 2.5 crank so...

the pilot for the .15 won't work (thread size way too small)

I bought a New Era pilot shaft for a .21 conversion (uses 2.5 clutch, flywheel, etc.) and apparently standard .21 shaft tread is still smaller..(really close, but still doesn't fit)



Can anyone help me out here??
