[VB] 1600 sp …

Hi JDD,
Depends on how you drive it.  Have now over 125,000 miles on our SP 1641 (slip in cylinders) SP engine, and it still runs like new.

If you are going to go for the machine in cylinders, one might as well go to a much bigger ID.  Problem with machining the case is you weaken it and run more of a problem of having the case crack just in front of # 3 cylinder and pour out oil there.

Personally next engine will be trying stock 85 mm P&C with 78 mm stroker crankshaft.
