Engine and Bottom End / Re: enough demand for billet cases yet?

i found a junk clutch cover to measure and start working on. we shall see what creativity hits me.

the thought came to my mind to just make a weld on ring that the CR250 top cover could bolt too. i am going to explore that idea also.

it would probably be 1/2" for the ring and 1/4" for the cover. a machined edge on the ring for welding to the clutch cover. and then tapered head bolts and machined receivers on the quick change cover. i will try to build a bill of materials out and start working on cost and retail pricing next week.

i think i could use standard flat stock aluminum plate and have them cut the rings and cover on the CNC plasma cutter. they would not be as fancy as actual billet parts but it would be just as strong and 1/3rd the cost. is their an argument against doing that or is this a 'BILLET OR BUST' part?

to make it a little fancier the top cover could be cut out of diamond plate.

thoughts or concerns?

when i looked into doing cast cases they needed me to order 100 or more of each side and then i would need to finish machine them. that is out of my investment range.

i could do quick change rings and covers i am sure. maybe even a full clutch cover, i will look into that.

Last step is done with hand held power tools, like finish porting or polishing, etc. Tie rod, intake, exhaust.

i think i have an unfinished intake and maybe a exhaust flange left from the last run of things. i will see what is laying around and post something.

this is a side project i have been working on for years, i have in the past produced a ton of 250R parts myself and also had 2 other manufactures make parts of my design. from air box removal brackets to aluminum intake manifolds, tie rods and motor mounts, exhaust flanges etc. i have started on the designs for billet case halves and there would be optional features you could choose for cylinder mounts. say you wanted to use a cr500 jug for a lower cost 500cc build.

it looks like 1500$ for a bare block of metal for a case half, and i still have a bit of design investment but i am sure i would cover that, so essentially the case halves would be for sale at cost of time and materials. (ball park of 4000$ full set, with a small discount on standard trx250r jug pattern probably)

there is no real benefit to billet cases over cast and finish machined. unless you did want to run a cr500 or polaris 400 top end, but with the sphynx and sabertooth and pro-x stuff all still relatively available there is not much of a need for that customization work either. the other benefit is that i could do a run of 10 sets instead of 100 or more like the casting manufactures want to do. so i can reproduce them with a smaller initial investment.

my question is are these viable yet or is there still enough aftermarket that billet cases are not needed? (i have been out of the loop a while working on other projects, your input is highly appreciated.)

if someone would like a pair for free if they will test and endorse the product or give me feedback on failure or miss fit, arrangements can be made.

Quote from: jcs003;68041

7075 should probably be used for the tie rods. They should also be hard anodized for ATV-offroad applications.

i do not have the spec sheets in front of me but from memory it was 6065 t6 hardened rod. the machine shop doing the work normally makes huge hydraulic machinery and i personally know most of the team. they know metal. period.

i know basically no one on this forum knows who i am but a long time ago i went into business with a machine shop in cali churning out billet ATV parts and after i did the design, research, test fits, marketing, etc. the machine shop i was using took all my work and wrote me off and started selling the parts themselves. due to a slight design alteration i still see MY parts by this company sold today but i was young and naive at the time and it was all verbal agreements based on trust so i was SOL.

i did not randomly chuck scrap metal to a lathe and pop out tie rods, i have done ATV and automotive work since i could read.

I would very much like to aid the ATV community with some new parts for sale, but i have other priorities and no time for convincing people that this is legit. maybe someone on here is old enough to remember and maybe they even have an original set of billet 450R motor mounts, or tie rods or air cleaner box eliminator mounts. (there is a picture of one of these mounts on MY fourwheeler being used for sales purposes still)

this has to be a self sufficient sells system or it is dead in the water.

sorry for the rant.

Gotta sell some parts or project dies. Hoping to fund cutting billet cases with alternative top end mounts. Think counterbalanced cr500.

finally putting some stuff up for sale to help fund further development.

the exhaust flanges had a couple small adjustments made by hand but are guaranteed to fit and function correctly. includes high temp o-rings.
47$ shipped 5 available

tie rods available in 12.25" and 12.75" (if enough request for other sizes i can do batches in other lengths.)
84$ shipped 4 pairs of each size available. Currently only available for brushed. if you would like polished i can do that at an additional fee.
