what does ported and polish mean, how do you do that ive tried searching the site but couldnt find it inthe ho wots.

changing the port dimensions for added power or different power characteristics. And polishing the exhaust port for smoother flow, they'll usually remove excess casting flashing in the intake ports too but those dont get polished.

it means that the exhaust ports have been opened up and smoothed out for more and better air flow. basically take a dremel or small grinder and open up the cylinder ports and passages to allow more air to flow. but if you have not done this before take it to someone as not doing it properly is going to make tuning hard as on cylinder may draw more air than another and cause tunning headache.

Not exactly opened up, you can also use epoxies to make the ports smaller. This is generally why flow testing is done on a bench. If the ports are believed to be larger than necesary and not creating enough velocity then the epoxy can be applied to make the engine flow faster.

If you want anything ported my brother does it Here is his website www.headdynamics.com

what do you use to polish it, car wax

Nope, you use a dremel with a smoother bit on the end so it doesn't take off a lot of material, it just smooths it out.

 

[ski-dooguy]

do you smooth the piston?

 

[bundox4life]

no, you just smooth out the ruffness in port, the intake you leave a little ruff but not a whole lot.

what is the port and what is the intake

 

[RX1CBPP]

It sounds as though you shouldn't be doing this yourself and you should let the professionals do it. For future knowledge, a port is what is on the inside of your cylinder and it is basically a hole. There are several different ports on a cylinder that have different purposes aswell. The are transfer ports/intake ports, exhaust ports. etc. These ports control the way the air and fuel goes in and out of the cylinder. Lots of times you can alter these ports for resulting HP. Probably the best bang for your buck in terms of HP but with power and more HP comes unreliability to a certain extent. Hope this helps

agreed if you dont understand what port is what this is something you should not be attempting on your own. get them professionaly done and ask who ever does it to explain and show you what they are doing, that is if they are nice and will let you. im not sure on your age but you sound young just tell them you want to learn.


cheers

ya i wouldnt recommend u doing this at all if u dont know what a port is and where to find it..... personally i wouldnt even get it done to your sled proffesionally unless its a huge ass mod sled. In most cases guys end of losing power on their sleds because of this.
