hoser,
Forgot to ask; you said the piston is 75mm, do I need to change the jets on the stock carb? I'm going to run it with a DG pipe, and may be 94C, but everything else is stock.
When ever swapping to a after market pipe I always go a few sizes bigger on the main jet and lower the clip on the needle at least one notch so it will richen up the mid range too, this is a starting point you need to monitor the jetting and verify its rich enough for the new pipe.
I doubt you will need to change jetting because of bore size alone.
