update on my project.... took it apart and did measurements. piston is 41cm ex.port was 19cm so I opened it uo to 24cm. i did nothing to the carb inlet port as it was the same size as carb bore, the strato ports i cleaned up for better flow.


what do you all think? will this make a good improvement or go bigger on the ex. port?
