Has anyone seen this video (http://www.youtube.com/watch?v=onioqw0w38Y) before?

Does any one no this person(s) who are in the video as I would like to find out some information of exactly what mods have been done to get this performance.

It says he has a mikuni carby on it but which one. I went on show and go Motorcycles web site (http://www.showandgo.com.au/mikuni/mikuni.htm?mikuni_bf.htm~mainFrame)
and they are so many different ones. Which one does the guy in the video run?

I am in the process of putting a tuned pipe on my bike. I have ridden my mates bikes who have tuned pipe on there bike and have notice that both there bike are staved of fuel (mainly on the top end)and I think more power could be extracted from extra fuel flow. So I wanted to put a better carby on my bike when the tuned pipe is installed.

Also what gearing do you think this guy is running?

Is your 18mm mikuni carby the round sided or flat sided?

Do u think a bigger 20mm or smaller 16mm is needed or is 18mm the right one for the job?

I have a 18mm Mikuni round slide. I believe 18mm is the max. A 16mm might be less tuning as I had to change pilot jets and mains....

I hit 35 mph flat road with my 27 sprocket so if i can have more speed i will have to change the HT for having more fun.

Im sorry I am not familiar with that carb, must be new. It doesnt look like any Mikuni I have ever seen. I got mine off ebay, listed as carb for 1970's 80cc Yamaha dirt bike, I think it was a GT80. It has the same type of clamp that the stock carby has so I did not have to modify the carb or manifold....

This looks like the carb I purchased..................Note the mounting flange.........
