Has anybody ported the exhaust ports? and if so what were the results. i hear people always talking about porting the intake side. but what about the exhaust side. ive never had the oppurtunity to tear apart a renesis so i really dont know. Can the exhaust port be bigger? how about a bridge port? i really need to get a hold of one to see for my self. im not yet ready to tear my motor aprt just to look.

 

Wow, look at that search function go.............................
