I believe it will all depend on the mods you have on the bike. If the motor and carbs are stock, most say that porting is useless and can actually decrease hp. Its not just getting the ports as big as you can, it all depends on the motor and how you want to ride

actually there are many ported heads running around. Not something most take a picture of before reassembling a motor.

If you're willing to search the site, there have been pictures posted

Here is some work from BigKev..
Cylinder Head Gallery

I would suggest you send them to BigKev or a builder on here.
If your porting skills are as bad as your people skills, that is. :rolleyes:

Lesson 102 about head porting...if you have to see pictures or ask questions you most likely don't need to be doing it yourself.

thanks t dilly for the pics thats what i needed to see.as for people skills i dont have time to listen to the idiots that read something about porting once in a magazine.ive been porting for over 23 years.i know every form has a bunch of einstein and about 2 guys that know what they are talking about.now that being said,if who ever paid more than $100 for the port work i seen in the pictures got jacked.not very semetrical or even close to be finished..

ill be happy to post our pics when im done.they wont be hogged out as much as the ones in the pic.we are not trying to turn 10gs with the engine.we expect to raise the rpms up from 500 to 1000.were raising the compression,cams,head work.tune and a small shot of nitrous.we will also post our dyno results when we are finished.

now if you want to know if i know what im talking about go to you tube.type in mouths gsxr 1000,thats my bike.these are some of my engine passes.i have 2 stages of nitrous i will be testing as soon as it warms up.

Nice videos. I saw one where it ran 9.40s, that's what the guy with the cap and shorts said. Then another, on the bottle I think I heard a purge at 25 seconds in the video, where it ran 8.90s I believe. Don't they run around mid to upper 9s stock? I don't know I'm asking.

Wow internet tough guy. Yes I measured but first had to go ask for a picture and see exactly what was needed. Posted it on another form. Lucky a got good advice and the job got done but I am sure it wasn't perfect.

Now that we got that out of the way. Hope your build goes well.
