You just want me to come back to your village.........

I don't thin it's terrible. The front hub to ski mounting colution ought to be better, but it has some promise. If it snowed more around my place I might could get into something like that. :cool:

The springs are more durable and provide a much more consistent launch/torque surge absorption. Most folks probably would never notice it, but if your a high-end drag racer or simply a fan of the better engineering solution, then the springs are the way to go. :geek:

Both post are accurate per my line of thought........., but it might not read very cleanly in this case. One other opinion that I have is that if you're going to do straight cuts, you might as well do the spring dampened Hinson unit. The benefit from that setup is a major attraction to me, and the fact that it happens to come with straight cuts gears is a secondary thing. :geek:

Dave actually shares my base blanket opinion on this subject. The only other reason to run the straight cuts is if you want to change your primary gear ratio, then a straight cut hear is easier to manufacture. :geek:

WCR is rad, but just incase these guys are closer to you, try googling Yakkey or PM bansh-eman on here (he knows how to spell Yakkey). :cool:

It's not like you to be late for a goat rope.............. :biggrin:

Pot stirrer......... :biggrin:

I apologize, I read threads and my mind skipped to the form of visualizing CFD results as opposed to actual tell-tale testing. Would you be willing to share any pictures or video of that? I would like to see it, regardless of any technical value, though I appreciate the fact that you may not want to show it due to someone might steal your ideas. My head was anodized, not chromed...... I shall also not continue to respond to the thread as it seems that we really aren't getting anywhere............ :thumbsup:

If what you are saying is true, then I have two questions: 1.) What is the thinckness of the boundary layer of air flow across your lower reed petal at 7000rpm'ish (with regard to your previous comment MT and Boyesen will help with bits and pieces of test data if you ask them for it)? 2.) Why do you tell people that you have never refunded money to anyone for any of your parts, with the exception of one mis-ordered parts? You must certainly remember refunding my money for the head I bought from you in which there were no standard Banshee domes on the planet that would fit them. I do recall the attitude of the guy I spoke to at the time of those dealings to be about the same though. Interesting..... With that said, Chariot is definitely trying to do something good for the sport is the face of a terrible economy and an even tougher market. There is something to be said for that. :thumbsup:

.........well like I said. I think there is something wrong with the design. I have a hard time justifying the time spent, buying, trying, and possibly returning, a set of cages that I do not think will accomplish what I am looking for. If I bought a set, returned them, and came back here and said they were crap...........would it matter to anyone, probably not. That's just m,y $.02.

You might remember that I am also the guy that says Trinity isn't all that bad if you pay close attention to what they are doing for you. Every once in awhile, they hire some folks that are good workers. :biggrin:

By no means am I trying to bash Chariot. They seem to be making a good effort in pretty rough business. On the other hand, the guy in this thread that said they do the same flow bench testing as everyone else, probably needs a bit of a love tap. If you are actually interested in what I think about what's the better reed cage, then here's I've got based on what I've run/tested: *A Boyesen RAD Valve is the way to go for a stock bore/stroke engine with something up to moderate port work. *VF 3's seem to be the way to go for the 10mil and larger engines, especially if you have a cylinder that does not use an OEM Banshee reed cage. *For the middle ground of engines (4mm stroke, w 65mm-68mm bore), I have not found something I am thrilled with. Boyesen doesn't cut it, especially if you are over a 35mm carb, and the rms of the VF 3's and VF2's isnt what I think it should be. I have tried a couple other cage manufacturers (Pyramid is one of them) for this configuration, and they performed so poorly, it's not really worth talking about. I disagree with regard to you remarks about scientifically proven products. If you properly plan, assemble, and tune your engine based on information and measurements that is properly gathered, then you will be hard pressed to find someone who is simply assembling things out of forum fodder that will come close to beating you. Granted there is alot more involved in winning a drag race, but you can see where I am going here...... You might be wondering at this point, why I have not run a set of Charoit cages, especially if I don't have something I am completely happy with in my red bike. The answer is this: Chariot doesn't seem to have any flow bench data available at all. That's not really the issue or even a deal breaker. I actually see a couple design features that I do not like in their cages, and would really like to see some data that shows that the cages don't do what I think they might do in transient flow conditions. :geek:

I'm an asshole................ and I approve that message. :biggrin: The point I am always trying to get across: is that seemingly in this buisness, dyno testing, flow bench testing, etc. gets advertised as making something better than someone else's something. In this case Boyesen and Moto Tassinari have fairly unique (read: expensive) blow-down simulation flow benches. Since there are actually very few of these benches out there in the world and since they are very expensive, it is easy to assume Chariot does not have one. Based on that, Chariot cannot say that their flow bench testing is thae same as competitors, which means there engineering effort is much different. Their product may or may not work the same or better than others in the realm of scientific engineering approach. Thus they compensate for that with the money back gaurantee. Which is certainly the way to go, but at the end of the day if you were researching reed cages purely on data available, you could not compare these cages to others. Hence, why I would not spend my money in their direction. :geek:

I doubt my statement is incorrect. Do you actually have a flow bench capable of accurately simulatiing blow-down conditions? What is the manufacturer and model number of your bench? I agree that one cage doesn't fit all cases. I also agree that pure flow rate is not the measure of reed cage performance. I am definitely not try to be an ass, but I really doubt that the level of engineering that is put into your cages meets the level the "high-end" consumer should expect out of such a technical part. :geek:

My bad. Wouldn't is what I was going for.... :biggrin:

Unless there is some blow-down capable flow bench data available for those cages with their prescribed reeds, I would throw any money their direction. There are only a couple companies that have engineering behind their reed products with regard to Banshees (Boyesen and Moto Tassinari). The rest of what is out there is largely non-professionally developed. :geek:

Do we have any idea what these things might look like? :geek:

Word. IR all the way! :thumbsup:

If cash isn't an issue, do both. Otherwise the TZ and max load bearing is good enough. :geek:

I have a set of '06 stock cylinders with very little time on them and no porting. I would be willing to make up whatever you thimk the difference is in cash........... What do you think?

No, that bike belongs to one of Twister's customers. It has a Dean Sundahl frame, though I can't remember the name of the owner off of the top of my head.

They gave me one of those the last time I was out there............. I like the calendar, but there is a Banshee in there that both of my bikes are nicer than, so that month is kind of a let-down.

The IMS heel guards are the way to go if you can find them (they are not made anymore). Other than the fact that they are not made anymore, the downside is that you have to run the Roll Design foot pegs with them. If you rummage around on here, you can find pictures of my red bike with that setup on it.
