WDYT about this cheap carb synchronizer?

[matt_gs450]

Hi All,

I'm gathering tools and parts for a carb rebuild on my GS450T (another thread already about the carb rebuild kit).

What is your advice regarding a synchronizer? I see various websites that have a dual-carb sync tool for ~$100, and then on eBay I see this:

Since I don't imagine I'll be doing this job a lot (hopefully just once or twice) I would tend towards a less expensive tool.

Also, I see some sites have a specific caliper tool for adjusting float-bowl height. Is this what I should get or can I rig someting?

Thanks,
Matt

similar price to the mercury filled tubes....

their accuracy doesn't depend on the quality of the cheap guages, just gravity. You don't need a tool for setting float level, just a ruler of calipers or the like.

I just used the 4 cylinder version of exactly that to do a sync, and it worked well. The only tip I'd give is to hook all the gauges up to the same cylinder before using it to see if they all read the same or need to be adjusted.

The cheap sync tool will work just fine. You can even use the "pull one plug off and see how high the idle is" method if you don't want to spend any money - this is the method used by BMW so it's not completely tomfoolary.

Regarding checking float level with a tube, I've never done it before. I just set using a ruler measuring the float height and all my bikes have run fine.

That's the same version of the one I have, except I have four of them. I tested them with a Mighty Vac that I have and they were spot on. They are also adjustable so you can calibrate them. They've been making that same exact guage for decades I think.

The hose isn't the highest quality, I ended up putting new hose on mine.
