I wanted to know details about Porting and Polishing like what it does. Does it increases the power and top speed or just the pick up and zippiness of the bike or car. As of now more concerned abt bike. I know only little bit of it i.e it increases the compression ratio, so more fuel is added to the chamber in turn more pick up and speed.
I have recently done it on my Pulsar 150Dtsi. I was told that it is not meant for 4stroke bikes so it is risky. i was looking out for a new 2 bike either P220DTSi or Karizma. But some problems kept me far from buying and investing another 1lac for a bike. So atlast did some modification on my P150. No heating problems till now. the intial pick-up has increased better than before, haven't check the top end still have gone till 80kmph speed. It catches 80kmph mark quickly so as of now i am having fun riding my bike. Let us see the long term effect if any disadvantages are there or not.
I just wanted some scentific details about Porting and Polishing and a univarsal thread on this topic.
Thanks in advance.
