Regarding the 110, several thing we have noticed so far:
The 110 uses the SE255 cam, an extremely narrow cam profile probably designed (probably? LOL) for emissions. This engine has higher cranking compression than any other modern H-D powerplant (hence the compression release), and owners probably have noticed the propensity for pinging. This is also the compliant cam H-D is supplying with the 103 kit for 96" engines. It requires some pretty tricky timing maps to control detonation. The maps we develop for this cam will be quite different than previous timing maps. There are better cam choices out there, but we are building maps for this application because the dealers will be selling them by the bucketful. We will also test our current design cams in 96, 103 and 110" engines, but of course, this all takes TIME.
The stock header pipes and crossover system within does create some difficulty for the closed loop as reversion pollutes the readings of the oxygen sensor at some RPM ranges. This can lead to some exhaust popping in those ranges with some brands of mufflers. I'll post which work better than others when we test more. A true dual headpipe eliminates this issue, and is recommended for better performance.
The compression release enabled prototype ThunderMax is undergoing testing at Zippers now and will be a part of an already-in-progress board revision that we anticipate releasing shorty after the first of the year. Maps will be released soon.
Some clarification as to why I am ALWAYS vague about when a product will be released: Testing is a dynamic process; meaning it can be ever-changing. If an issue with a component or process is found, corrections to that component are made, then you go back to testing. Upon more testing, there is always the possibility that the last correction or change can lead to more issues with another connected component or process.
This is why I can't forcast an exact date of when a product will be "done". It's "done" when it has been thoroughly tested and we are satisfied that we have a product ready for market. Once that happens, production parts are made, and then have to endure another round of tests to make sure the production parts do what the prototype parts did.
At this time of year, lots of testing goes on, for many different products. Along with the ongoing ThunderMax development (this product will always be undergoing some type of testing for new or enhanced features - and as they envolve, you can update yours with an internet connection), we also design and manufacture our own line of camshafts, cylinder head designs, complete engine kits, participate in the testing of software and many other products such as upcoming 1-piece 54 and 60mm throttle bodies, fuel injection for the Sportster, etc, etc, etc.
When H-D releases a new engine platform or three, there is a lot of work to be done. We are a small company (30 employees, everybody works, no desk jockeys) which is both a blessing and a curse. A blessing because we can respond quickly to changes, a curse because there is only so much we can do in a day (we're only "one-a somebodies"). Some folks have mentioned here that they think we have taken a cavalier approach to them or their problems, wants or needs. This is not the case at all. We didn't get to where we are (25 years at this now) by shirking our responsibilities to our customers, and that will never change.
I will be working for the next few months on updating our catalog and will not be able to participate here as much here as I would like. I will respond to PM's and jump in here when I can (there have been and will be gaps), but suggest anyone that has any questions about our products to call our sales team. Bill, Pat, John Williams, Pete and Lisa will be happy to help you. But if they tell you they can't give you an exact delivery date on a new product, it's for the above reasons. But rest assured, we're on the job.
As always, I/we appreciate all of your business, past, present and future. This board is one of the more civilized ones on the net, its members reflecting the reason I got into this business in the first place - because it's fun! Thanks, JK
