I would try the 4 degree key first personally
Not to sure about the carbs. 165 to175 mains and 50/52 pilots seems ballpark depending on how aggressive your portjob is.
Any time you use a stroker crank with or without a spacer you have to change the port timing for best performance.
If you have already been ported for the spacer/stroker and want to change the setup to no spacer and cut head i dont know what kind of situation you will be in with porting. Im sure it will need to be changed though. |
