SyncLink vs. VdubEngineering cable linkage kits

[R2.0]

I am gathering parts for my T4 build and looking into carb linkages. I'd heard good things about the SyncLink system, but while searching for that I found a system made by Lanner at VdubEngineering.

Does anyone have experience with either? My understanding is that the Synclink is probably the original but Lanner has a good reputation and his is cheaper by a substantial amount.

I've run the SyncLink for the last 8+ years (on dual 44IDFs) and never had any issues with it. Easy to adjust and stays set, and Pete is a great guy to deal with. I can't speak to the vDUB Engineering version. It does appear less cosmetically refined than Pete's SyncLink, but Lanner does quality work so I would have no concerns with the fit and function of his.

Or is there a 3rd way?
To eliminate the balance adjustments run 2 throttle cables.
One from each carb to pedal. Extra adaptor on pedal.
Imagine opening the engine lid and baffled faces.
No clutter or extra parts to wear /fail. Cable strain reduction 50%. Cost reduction...

Quite a few motorcycles/ATVs (e.g. Norton/Yamaha/Honda) use a simple 2-into-1 throttle cable. I've thought about trying to adapt it to my current SyncLink setup since I already have the brackets and pulleys, but it works great as is so why mess with it.

Hi!

I run the Logmech unit although slightly modified for my application.Works really good and is cheaper than a crossbar system.

Some things to consider:

Things like threaded rods, other than a potential early stretch can usually change the length some. Smaller diameter twisted together material/wires/connectors can too but not only once.

Flexing, flapping, stretching and length like a rope can (and usually does) the smaller diameter connector material. Some people run them through a tube not just for the potential action but also getting "hooked" onto something.

The wire joins to the pedal or carb arms can also cause a wear pattern to the materials.

Some carb setups are very susceptible to movements.

A few thoughts and there may be more things one could run into.

I forgot to add "push/Pull" not usually good using the thin metal materials.

Also, there is "AGE" limitations on how long something is usable. "Age" covers a lot of different things also.

I made my own Bowden cable linkage.
It had the pedal cable going to one throttle body & a slave cable going from there to the 2nd throttle body.

It wasn’t perfect however. I assumed it was due to the slave cable stretching but that’s not the case. The outer conduit (which is used to make balancing adjustments) compresses when the cable is tensioned, so the action is not linear.

I ended up swapping out to a CSP linkage which solved that issue but the cable linkage did have better progression at low throttle openings.

Ideally a centre pull version of the cable linkage would have been the best all round for me but I’ve got something that works for now.

I have a lot of respect for the guy who made the sync-linc, but, Lanner is a good friend of mine and has made many things for me so I know his quality level. I would buy from Lanner.

I like the thinking here.
Synclink is expensive. Make it reasonable and sell 10x more.
More than one engineering solution to achieve any goal.
Alternatives to the poor stuff big manufacturing companies churned out for decades all good.

Is Lanner still making these? Several other items he used to market are no longer available.
