home made float gauge?? Need help

Postby bwagner6 » Tue Jun 05, 2012 7:47 pm



Getting ready to pull and go over my carbs for the first time. Any suggestions on setting the floats on a budget? Also was wondering if there are any Wingers that would be willing to help me sync? I live near Sandusky Ohio by Cedar Point.

There is one tool I bought that I find indispensable.A mechanical dial micrometer.Bought it at Harbor freight.It can be used for what you need.http://www.harborfreight.com/hand-tools ... 66541.html
Even if it's used to mark a piece of plastic for cutting a template to set the floats.

As far as the sync...I'm a bit far for a day trip there,so if you can't find help,here's a homemade sync tool I made for mine.It is easy to build,cheap and makes the sync job quick and accurate.I use it on all my bikes.No more fluttering gauges.http://www.goldwingdocs.com/forum/viewt ... 94&p=40711

Thanks for the info.... I did find a guy about 45 mins away who will sync for cheap so I will go that route this time.

You'll know right away if it was done right.
The bike should start to pull from a idle through 2000 rpm hard and without rattling the engine.
When you let the clutch out at 1000 rpm and just idle it several feet down the road,twist the throttle about 1/2 way, it may grumble a bit but not sound like a bucket of bolts shaking around.
Good luck.

Pulled the carbs today and found 2 slow jets clogged. Got it all together and she purrs nice now and runs strong at all rpm. I will take it for a sync this weekend just to fine tune it but all in all its running real nice. Thanks for the info.

Good job.
by the way,when was the last time the timing belts were changed?
If your answer is "over 3 years or over 40k miles or I don't know" you should spend the $40 bucks and replace them.

My 85 Aspy has all of the lean symptoms. I rebuilt and synced the carbs, job well done I might add. Runs bad at idle and steps out rough. I found one float radically out of adjustment compared to the other three. Adjusted it to match the others which measured to spec. However, Couldn't start it because now I have to rebuild the starter. "One step up and two steps back". Any thoughts on the carbs?

It dosen't take much of a fuel level change to upset the mixture.If just one of four carbs is off,there can be a 25% change in overall performance.especially at the off idle rpm.
For example,my 1500 was rich in the 1000-2000 rpm,I lowered the floats just 2mm to lean it out.
The ammount of fuel needs to be exactly the same in all the carbs to be able to deliver the same fuel at any rpm.
So if you found a problem,it should solve the trouble.
