Sorry guys to the ones who PM'd me. I rarely am on this forum but I do still pop in from time to time. Yes the top has several radii. If the 3D models aren't still available let me know.

They work very well in fact (as Tweety, myself, Rick and others have noted). The thing is that those of us who wanted some and forked out for them now have them, so it`s a dead issue. What is the point in trying to sell the merits at this point in time? We have all moved on to other projects...
BTW, the same CAD drawings we used to have ours fabbed are still available so all you need is to find a few more takers then you too can smile under your helmet when you roll on it....

Oh I got plenty... How does one of a Nitromethane *****'s Coupe at about 1380 Bhp sound?
BTW... It broke the dyno...
Bent one of the restraints for the front wheel and snapped the other... Safety tiedowns held it... SO now I got welding to do...

Keep this out in the open. Every time I open the packaging for my stacks I have a new-found appreciation for how good they are. My Superhawk comes "alive" in cooler weather b/c it's a little rich. Tuners tell me stacks will lean it out. It's two screws. We'll see - the next tank-empty - it's coming off.
If you guys can pull off another run, all you guys with jetting problems could consider this as a first stop solution.

They defiantly work. When I ride the street bike that does not have them and the track bike which does, you notice the difference. Both bikes are set up the same except for the stacks.
After I installed them, I had the bike on the dyno to see what my air/fuel ratio was. It confirmed what everyone said. I was running rich and needed to drop the mains one size. Next spring I will put it on again to check and see if that was enough.

Hi Guys...
TXSuperchicken asked me to come over to this board to help out with machining some fork braces, but in that thread, some guys have asked about reproducing this set of velocity stacks. Once the braces are done... I would be more than happy to reproduce these for you guys without any minimum quantity. The CAD drawings were already sent to me, and I will start to work on them soon.
Lastly... you can post interest here... but once I turn the 2D drawings into a 3D model... I will start a new thread.
Just an FYI.

The reason for alu is that it's light... Making those out of any other metal would make them very unnecessary heavy and that's bad...
Machining stuff out of plastic takes special machinery, either for casting (which is imprecise!) or for machining you'd need special toolsets...

There are places around here that does too... When I asked around my conclusion was that alu was going to end up being cheaper since there was more places doing that...
But you could get different results... It seems quotes on CNC parts are like lottery or stock markets...

Hi Guys,
The only nice thing about plastic, is it cuts like butter, as long as you keep it cool. As soon as it gets a little warm... it melts.
Right now, I can buy aluminum cheaper than most cast/extruded thermal plastics.
Most common grades of aluminum machine easy. They are predictable, and don't melt easy. There are a few high silicone aluminums that you have to machine slow... and some of the purer grades (3003, 1100) that are soft, and stick the to the tools, but 6061 or 7075 are a dream to machine. Also... they can be anodized nice pretty colors at a reasonable price. If there is enough interest, I can have them anodized, and it should only add a few $$$ to the price.
