Porting Question for the masters (Don... Ect...)

rx1mtnman said:
My wifes viper burned up magneto side piston and cylinder. I found a cylinder with only 888 miles on ebay however it had been ported. I emailed seller and asked if it would be a problem that my other cylinders were not ported he said no butt might need to run different size jets on that cylinder. Is this correct? Should I run this cylinder on PTO side were there is less compresion or should I port the other two cylinders or should i try to find another cylinder?

either port the other 2 cylinders or find a new stock one. don't run ported cylinders with non ported ones.
 
The "ported" cylinder I found on Ebay appears to only have been filed down on the lower part of the exhaust outlet. Does that mean that the head would not need to be modified to keep the same compression? Also if I had the other two cylinders "ported" does anybody have any recommendations on whom to send them to and approximent cost?
Thanks
