Digital carb sync tool

[CleoBen]

Has the VRCC considered purchasing a digital carb sync tool for its members to borrow or rent?  Seems like a lot of expense for a tool likely to see limited use for a non-mechanic-but-mechanically-inclined Valk owner.

As an alternative, would any VRCC member that owns one consider loaning it out to a fellow member for the cost of two-way shipping?

The VRCC, no.

But many locally have offered. You have your location in your profile, it might be better to post asking if anyone local to you has one and willing to share.

I've posted mine in our Chapter forum, and bring it to our Rallys. No one yet has used it, too busy riding.

Buy this one for cheaper... (not mine)

That's a deal!

Agreed. Thanks for the link.    I bought that one and look forward to using it.

Will not have a chance to use it till spring. Have been wanting to sync the carbs since I bought the bike. Past owner mentioned one carb had been replaced but no mention as to why. I rebuilt them all a summer ago and set the pilots but had no means to check the sync.

I tried an analog vac gauge with a 6 way air valve distributor but got way too much needle flutter. I tried closing the valves to reduce the needle flutter. No go. I bought an air snubber and never got around to trying again.

You will love the Digisync.

For you and any others that may want to use a gage or manometer arrangement, put a volume bottle in the line just before and the gage/manometer (or any other measuring device) to provide damping. To get accurate readings, all cylinders should be damped the same hence any damping device should be common to all cylinders.


The hookup to the measuring device should be volume bottle first, needle valve next  and then the manifold.


Probably the easiest/cheapest volume bottle can be made from a capped piece of PVC pipe with installed barb fittings for the tubing. I would suggest that a piece of 3/4 PVC about foot long would be about right. The bigger the volume, the greater the damping.


As damping is increased, the sensitivity goes down. The measuring device needs to be left with a small amount of flutter.

Please let us know when you get it I'm assuming you would be will to lend it out, RIGHT? 

Just kidding I don't need one at least at this time.

But seriously let us know how you make out and if it was helpful!
