I have several PMs from different people , some that were involved some that were on the sidelines , that plus what is on the original thread and what has been posted here , I think I have pieced enough together to answer my questions though.
That’s true. I was working with Calvin in 2011/12 (maybe late 2010 we started work) to create a triple cast Kawasaki 1200 for racing. He was taking the doo sledshop cylinder and machining the sides for 120mm centers, then we welded the castings together and the added the holes for the zxi cases for the first prototype. He told me about the then Yamaha PWC twin work. I probably have the early pre machined pattern pics of Eriks cylinders I believe that’s how Erik and I first met through Calvin. I never ended up finishing the triple project since market was just too small and word was getting around the sxrf was coming out in a couple years
That's the problem. Remember that dude who found America but didn't claim it.... people are brainwashed and sipping the kool aid, often forgetting to cite the source.
Not sure on all that. But if I started selling X-H2O 989 Cylinders and having CPI make then, I would not be advertising who made them.............. I was just pointing out that I never heard of them. The info may have been posted and never saw it..... neither here nor there honestly.
From a business stand point yea, I guess. But its more so to point out the fact that it is NOT A COPY and it's been in production for over a decade. All of the i.p belongs to cpi and always has. Modifying the cylinder is what can make or break the package.
I thought the whole point of producing this cylinder is that out of the box it would out perform a Dasa or other type cylinder and that it didn't need to be modified , yes I get that the cases have to be drastically modified for the cylinders to work properly and the pistons to clear but the cylinder needs to be modified too , that doesn't make a lot of sense to me , maybe I am missing something here ?
Your not wrong about engine prices being through the roof, but it comes down to a manufacturing stand point, higher number=cheaper cost, lower number=higher cost.. The good thing about competion is it makes the sellers be more competitive with their prices.. Or Atleast it SHOULD!
2003 the MFG's pretty much pulled out of National Racing......... The Big Rigs were gone as well as the money. A few racers like Farthing and McCluggage still got some sponsorship, but not like they use to get............... 1998/1999 the IJSBA did away with the Mod Class, which damn near killed the AM parts suppliers....
Don’t wanna put words in Tony’s mouth but I think he’s talking more about the setup. The cylinders do work really well out of the box. You can tweak how the motor performs by playing with the port height for example. There’s finish work you can do to the cylinders to get some extra power. The design of the cases is a big factor in why the JSN1200 works very well but ultimately the design of the cylinder is where the power is made. The shape and placement of the transfers is a huge deal. The PV configuration is unique as well.
