I'm looking at a 05 YZ 125 for sale that has been bored to 139 and then stroked 2 MM. The bike is set up as a woods racing bike including "porting for woods racing", and a fly wheel wieght. How many cc's would this have?
How much would stroking 2 MM change the powerband characteristics and what is "porting for woods racing"?
I'll be riding the bike in +30 moto and like mid/top power. Would I be better off building a YZ144 without stroking??
Any opinions on this combo would be appreciated.
