2XT billet powervalves

[mboddy]

And as you can see from the pics, the 3MA valves that we modelled are brand new.

Hi

Is there any update when these might be ready

Thanks

Did these ever get finished? I would buy a set

[wwild]

Since I have been looking for 2XT Power valves for a really long time now without success, I have remodelled mines.














I would like to have them CNC manufactured.
However, the costs are immense for a single set: they want 780 EUR    .
If I were to order 5 sets, the price would be around 260 euros/set.

Now my questions:

Does anybody know, where I can buy 2XT Valves ?

if there is no source to buy one:
Is anyone interested in one or more sets?
Does anyone know of a CNC milling machine that might produce at a lower price?
I have chosen AL6081 for the valves, What do you think shall i use 6075 or is 6081 good enough? The difference in the price is approx. 5 Euros/set


I will now have the individual parts printed in plastic to check my design.

Regards
Werner

w - I like your approach, except of all the places to look for a bargain, a machine shop is not one of those places. Now, that doesn't mean a smaller shop might have lower overhead and still do amazing work, but in general you pay for what you get with bespoke parts. CNC machines are expensive. The guys that invest in them need to see an ROI.

Good Luck.

It's great now that a lot of us can just pick up the cad software and remodel parts to send out to machine shops, hopefully it will help to keep the bikes running longer.

I take it you have had stuff manufactured before?
Working in mechanical engineering discipline I do like to see others checking things like limits and fits. I've personally not seen a new powervalve spool in a new bush, so don't know what the design gap was set to by yamaha. That is going to be your main critical fit in operation and probably the hardest to measure from an old pv, as its a wearing surface . Obvs you need to communicate that fit to the machinist with some good tolerances, or supply a set of new bushes and ask them to match them with an appropriate fit.

I think you'll find a good local machine shop is best as you can go to them and talk whilst looking at the parts.

However if you want to know a ball park cost you can upload cad models to places like 'protolabs' who will quote to machine it, but they only offer global tolerance of 0.1mm (I think) which is fine for general stuff but may not be suitable for the fit to the bushes.

Good luck!

Also, other cons for protolabs are, they charge more than any small machine shop I've dealt with. Partly as they offer a very quick service.

They also don't like having to do multiple setups or operations on separate machines, ie they do not like milling and turning on one part.....they'd prefer to do it all on one machine. Again to keep cost down for them. Where as a small machine shop would likley be happy to use multiple set ups to ensure you get the part you need.

Hi...it might be a 10 YO  post but now that the powervalves aren't anywhere around , has anyone scanned them  finally ? . Only option is cnc made  I think . ANY INFO is appreciated !!!
