Hi all,
I'm going to rebuild my engine this week.
I would like to know :
Which piston should I use for my next 416 bore? I would like to use 11.5:1 or may be 12:1, but who makes them? Will 12:1 could be good with 91 octane?
Which year of CRF 450R timming chain I need to use?
Would I need to use HD studs with that 416 setup? (look in my sig)
Will my crankshaft will be ok will that load?
I will also replace valves seals, do I need to replace anything else (reliability)?
Thanks in advance!
