    Velocity stacks

    Anyone have a used set of velocity stacks that attach to the diaphragm caps of the 1200? I know I can get them new for around 150, but, money is tight and I just wanted to get a set saving a little. Just thought I'll reach out and see...thanks, Steve Kent

    Velocity Stacks

    I read the sticky and I'm going to try it out, I couldn't find copper than wasnt exorbitantly expensive so I went with some 2" stainless exhaust pipe from autozone for 16 bucks, I also found that the 2" fernco fittings were 2 and a 1/4 so I went with 1" 1/2 ferncos that fit with a little...

    velocity stacks in air box

    inside the velocity stack, yamaha created a high velocity port just before the carb venturi, meaning they made the velocity stack smaller by 19 % , for about 1.5 inch to accelerate the air speed to get better atomization at the needle and get more air into the pilot jet. did a test cut the...

    hight velocity

    Hy, does any of you heard about ** hight velocity carburation and exaoust ** based on reducing size off intake and exaoust diameter as much to 30% , this result to an increasing tork at low rpm and as much as 10 hp on rear wheel

    Velocity Stack Screen

    Hey guys, anyone know a good source for some wire screen to put inside the extracept velocity stacks. I've been looking through McMaster Carr but its hard to decide on the gauge and the patten, etc without seeing it in person. I'm a visual guy and the images are pretty generic on McMaster's...

    flatslide carbs with velocity stacks

    Group, I'm in the process of purchasing a VMAX with this set up. 4" velocity stacks are in use right now. I expect that I'll need to change them, they're real awkward with a riders knees. One of the frequent contributors to this forum has modified 4" stacks with a 45 degree twist, to offer...

    Velocity Stacks

    Hello....While attending the Canadian Superbike finals today in Shannonville Ontario, I saw a (built 12/99) year 2000 Vmax carbon in the parking lot pulling a small trailer. It had some very tasteful mods on it and I stopped to take a look. In place of the diaphragm covers there seemed to be...

    Velocity Stacks with Indv Filters

    I remember someone here making velocity stacks with some tubing / pipe from loews. Has anyone expiermented with velocity stacks between the carbs and indv air filters on the stock VMAX carbs? If so what length did you make them, did they funnel or expand in shape of the body to increase air...

    Stage 7 with Velocity Stacks

    No stack at all pulls hard 7 K up and the mid range is soft. 4 inch stack pulls good low from 3-8 but will starve out up top. Short stack 2 inches better in top end. 3 inch stack allows me to pull down to 2000 rpm and up to 9500. With the K&N filters and stacks I had to put the float bowl...

    Velocity Stacks

    i saw somewhere it said that using velocity stacks, maybe 1 or 2" tall, inbetween the KN pods and carburators makes the bike run better? Anyone ever done this? Or heard of it? where did you get it? Also if I have stage 7 kit I can never go back to stock right? How about stage 1 could i do...
