[Fot] TR4 crank improving # 2 main

FoT

I have heard the oil passage in the # 2 main journal can be drilled out for
better flow

and  re-shaping the hole to better apply oil to the bearing.

I'm preparing a new crank and using Chris's new seal as well as shot
peening, 

cryo treatment and nitriding. I would like to improve oil flow to the center
main

if possible. Any information about drilling, re-shaping or just outright
crank improvement

would be appreciated.

Thanks,
