The tooling or molds will cost me about $400 for materials to make just the first one or the prototype. If I can convince the owner that there might be a real market for it I think I'd be able to have him help me make the molds and a short run of parts.

Any thoughts? The aluminum parts are kind of heavy and the carbon part would be virtually weightless at about an ounce. I could also do a carbon top snorkel and front cover too.
Talk soon Travis.
Carbon front cover, starter cover and square airbox would be of interest to me.
HPN already do a front cover for a weight saving of 500gms and a price that doesn't match my budget of
about $180.00 / kg.
I'm running out of affordable areas to shave so an adjustment to the funding model may be required.

Ruckster, carbon is not cheap. I honestly don't know what the individual pieces would cost but from what I've heard about HPN is you put in your order and you might get your parts a year or so later. And the sad part is they seem to be one of the only games in town. I'm really just feeling it out to see if it would be worth the investment to make the molds for my own set, and then if anyone would be interested in a set of their own. There would be an obvious weight savings but its also a bit of bling factor too. The molds really do cost about 4-5 times what a finished part would cost to develop, so unless I can see selling 5 sets of parts to cover my investment, its a big pill to swallow just for one set of parts. I may start with the airbox and see how it goes, throw a few up on the forum with generous pictures and see if anyone bites.

Talk soon, Travis

Keep in mind for the airbox that you'll need to either include some metal washer inserts in the layup or exclude the trans mounting studs from the airbox. I wouldn't want a nut torqued down on a carbon fiber airbox wall holding a transmission on. It'd hold just fine, but would eventually (quickly?) tear up the walls of the airbox.

Hpn

Actually HPN will send you the parts pretty fast. I never had to wait more than 4 weeks. Having them working on a frame it is an entire different matter

Tank

I have welded two mounts on my bike. The tank is on 2 silent blocks/rubber mounts in the front (mounting points) to absorb any possible vibrations. You may also make 2 removable clamps ala acerbis/hpn tank with 2 rubber mounts. The 4 screws on the top of the tank are for the HPN tool box or any other one you wish to install.

There are a lot of reasons to not have the subframe welded to the main...you create stresses you don't need and invite cracks. There is a reason that HPN doesn't do that...Structural Engineering 101.

Plus -- it's nice to be able to pull a subframe off if it gets bent and straighten or fix it.

Right, but back in the 70s most if not all the isdt/enduro bikes were like that...and that is an isdt replica..
