Billet Chain adjusters

[motopike]

Hi all,
I am a chartered aerospace engineer in the UK and Ive have designed some alloy billet chain adjusters that stay in place when the rear wheel is removed. I have 3D modelled them but not machined them yet.
Im trying to assess if there is a requirement for them. Is this something that would be useful to any of you? the original SV version seem rather flimsy.
Im open to suggestions for any parts that you would like designing for the SV! You can see other parts I make on my website, www.motopike.com (http://www.motopike.com)

Cheers
Adam

Which model, curvy or pointy?

I'd be interested in curvy ones

[motopike]

Only pointy so far as thats the only swingarm I have. But I cant imagine it would be difficult to design the same thing for the older model

[maviczap]

The other simple thing That I would like, if you don't do these, is stainless steel spacers for the rear wheel.

There's a guy doing them on Ebay for the Pointy, but not the curvy

[motopike]

OK, do you mean captive ones that dont fall out when the wheel is removed. Its something Ive considered. Would make them out of anodised alloy rather than stainless though.

[motopike]

I will design some.

Well once Bibio has finished using my spare curvy swingarm, you're welcome to have it to use.

Dont mind, captive would be good if you can design them to stay in place.

it will be interesting to see what you can come up with and at what price. i'll not make any more stock until such, as there is no point me shelling out funds if you can do a better job at a better price.

Bibio,

Have you been working on improving the adjusters already? Its not somthing Ive done a search on the forum for.
I assume the curvy adjusters are similar, but just have a different extrusion profile? I seem to remember they have the adjuster nuts towards the bottom of the adjuster plates as well?

cheers.

motopike,

you might be thinking of the SV1000 adjusters as these are like the GSXR variants. the SV650 are side plate marker style and do not have the block and bolt sled arrangement of the SV1000.

have a look at www.svbits.co.uk/brackets.htm and it might give you a better idea of the mk2 SV650 type.

the mk1 SV650 is just a simple rectangular plate that fits inside of the swingarm extrusion.

oohh and welcome to the forum. what machining do you have direct access to, if you dont want to say on an open forum you could PM me if you like.

Thanks for the info, I can get most parts made, in aerospace alloy. titanium, plastic, carbon etc. I dont do the machining in house, apart from 3D printing. As you probably know its the funding required to make large batch quantities of CNC parts that challenging.
Ive even looked at making parts using DLD (Direct Laser Deposition - basically 3D printing in metal) but its still a little too pricey.
The chain adjusters Ive designed have blocked that fit into the extrusion of the arm, allowing the adjuster to be spring loaded. I would probably make alloy side plates as well, similar to ther stainless ones you linked to.

I wont bother if its not an issue with the current design.
I made soem nice adjusters for the Yam R125 asthat bike doesnt have the holes for paddock stand bobbins as standard so it made a lot of sense to make a batch.

It may be good if I could design a set for the SV that fits either model.
