The potential of this cylinder over a stock cylinder is huge. I have done a heap of porting and while you may be able to port the stock cylinder you will never get it near to this cylinder

No they will not be

Thank mate. We will have the full system ready to go very soon. We will offer special pricing on the header pipes for anyone running our manifolds as well. Some more announcements coming soon

Yes that’s what I had in mind. Personally I hate power valves on a ski engine

No Dasa already fills that market. im going for a cylinder that the average guy can put on their ski and get a hit,

Yes cast

yes it will have sleeves we plan on starting at 81mm but allowing for big bore

Look what we are cooking up for you stock stroke guys

presale in about a week on these. yes it works with the stock reeds

Thanks for the heads up. Yes it’s something I have been looking into. Appreciate the ideas

Like a base you fibre glass into place ?

You may have misunderstood the post i made. I know these are programable. however a stroker crank does not change this. degree before tdc is still the same the piston is just moving a larger distance

I used to run the stock flame arrestor. Once you get to certain engine performance however it does create a restriction to the power.

Yes there will be a chamber

There is gains to be had over the stock header pipe and we are working with TNT on ideas with it. These can only be changed in the design faze. We will incorporate this in the header pipe we are making

I'm so excited to show this off, its a new product coming out soon. I made a few mistakes on this one and have to redo a few things but its pretty cool. Just silly little alignment issues and so its time to fix and make a new sample. As you can see the throttle cable connects to the bottom of...

Thanks for that, these are really nice for making the manifold easy to bolt on
