The wear marks on the flange are typical adjustments made to ensure the manifold sits well with the extractors. The GX twin side-draft manifold is very similar, if not the same casting to the JTS manifolds, quality is good with a nice solid bridge to join the pairs of runners, the provision of four blind bosses, one on each runner can be plumbed for vacuum reference. I prefer a manifold with an integrated throttle shaft mount as I find those threaded components holding the throttle bar to be a PITA, sometimes older units have sloppy threads and I have had my entire throttle assembly 'lift' before, causing much drama while tearing out onto a highway throttling a mongrel race engine.

The small collar with a tightening nut is a locking collar to stop the throttle shaft moving forth and aft (looking from drivers position). There are typically two of these, or sometimes one collar and an 'e-clip'. Looks to have a circular throttle bar which can be problematic when it is of a small diameter, over-springing the throttle return can lead to constant slipping of the throttle arms - this symptom is typically what creates the myth that 'side-drafts continuously need tuning'. This is not the case if set-up properly using the appropriate diameter rod.

$150.00 is a good purchase to include most of the linkages. A good starting base.

Thanks Chris for the comments.

The grind/wear marks on the flange looked to me like they were done deliberately as you suggested for fitting extractors.

The linkage assembly seems heavily used. I might consider buying a new linkage kit just to have a setup that is solid. I acknowledge your comments how a worn setup can cause issues with the throttle and the running of the sidedraft carbs.

Do you have a linkage kit that you would suggest for this setup new....where to buy?

I suppose also that I will need those spacers that go between the manifold and the carbs, and also trumpets or filters for the carbs too.

Thanks for the help.

Hi,

The linkages setup in my opinion is best made from quality parts sourced from hardware suppliers, the kits offered on-line are just not that great unless you can find someone with some real savvy, here is where I buy all my carb parts:

Dellorto UK

Quality linkage rod ends can be found at relevant hardware outlets, CBC sell good units.

As for spacers I recommend these, the thicker the better. Remember you may need longer manifold studs to accommodate the thick spacers.

Phenolic Spacer 1/4" thick

Phenolic Spacer 1/2" thick [reccomended]

So much bling

Do they make those for men? ??

I guess you can do your make up in It. What's the bracket for?

I believe it was welded on to allow for a center pull throttle cable setup. Which will suit my twin carbs juuuuuust nice. Hopefully.

nice color

WHOA, you even converted it to a LWB.
