For you guys with 3D Printers, this engine mount vibration insulator may be of interest.
It needs to be printed from flexible PLA with high percentage infill (I used 100% although better results at the expense of crushability can be acheived at 75%).
This has worked really well on the Chinese clone engine I have.

Over the coming month Aussie Cyclekarts and its associated resources will formally transition into The Cyclekart Club of Australia.

The reason for this move is to support the need for a formal body so that events requiring insurances can be organised. Some of this was outlined in the We Need You post made a few weeks back.

This change does not affect existing or future users of the website or social media channels which will remain free to use for non club members.

The main goal with club membership is that it will provide insurance for members participating in club events. So if you are not participating in club events, there is no formal requirement to be a club member. Of course, you may still elect to join the club as it will in time provide other benefits.

Club events may take on many different forms and includes both static events and dynamic events. Dynamic events are the events that require public liability insurance and include any meeting where Cyclekarts are driven. For example the monthly get together that your local Cyclekart group holds.

The intent is that the club provides insurance for dynamic events, like your local groups monthly get together so that you and your buddies do not have to. All that is required is that all participants are members of the club and that your meeting is conducted in accordance with the club (read: insurers) rules.

So over the coming month you will note a change to the website URL which will migrate from cyclekarts.com.au to cyclekarts.org.au and likewise a change to the email address associated with the site.

At this stage we have not determined the best action to take with regards to social media channels which all currently have the 'Aussie Cyclekarts' branding.

We are in current negotiation with the insurers to organise a policy that will cater for our needs. Once we have a view on what this looks like we will be able to finalise membership costs and open membership up to those who wish to join.

If you want to take advantage of the insurance for your local group meetings there will be some pre-requisites that need to be managed. Please get in contact for more information.

I've been trying to find a local source of springs for the club. Unfortunately the biggest barrier seems to be obtaining the correct size material. Most (all local) spring manufacturers use 6 x 40mm minimum size which is larger than the 6 x 30mm that is generally prescribed.

I even spent some time talking to tuk-tuk & rickshaw manufacturers in China and India but they too use larger material which is generally 50mm wide by 6mm.

I did some calculations on the locally available material size, using the renegade Cyclekarts springs as a baseline. These are 24" eye-to-eye, 1 1/4" wide and 1/4" thick, which equates to 630mm eye-to-eye and 31mm x 6mm.

Using a spring calculator this gives a baseline spring rate of 103.57 lb/inch

To achieve the same spring rate using the locally available 40mm wide stock we can increase the eye-to-eye distance to 660mm to get a spring rate of 102.31 lb/inch, which is only a marginal increase in length. The increase in length would effectively shift the front axle back by 15mm, which is more or less negligible.

So I think that for a small compromise in length we can get a comparable spring manufactured.

Here's the comparison
