Broncoboy36081 Posted September 30, 2014 #1 Posted September 30, 2014 Which is the better of the multitude of carb sync tools? Thanks

Freebird Posted September 30, 2014 #4 Posted September 30, 2014 It's not really very critical. Just turn the screw up a couple of rotations and then put it back about where it was when done.

Just turn the screw up a couple of rotations and then put it back about where it was when done. Will do. Just ordered the carbtune. Anybody know which carb is the master? Or does it matter with the carbtune. Is there any calibration process for them?

I feel these gauges are more accurate than the carb tune most people use here. Cost is about the same too. Larry

billmac Posted September 30, 2014 #8 Posted September 30, 2014 A long Phillips screw driver really helps to adjust 1&2. I bought mine at HF.
Peder_y2k Posted September 30, 2014 #9 Posted September 30, 2014 The most accurate and relied on by long experienced motorcycle mechanics/tuners is the mercury manometer type. There is simply no substitute for their sensitivity and accuracy. -Pete, in Tacoma WA USA
ACE50 Posted September 30, 2014 #10 Posted September 30, 2014 I'd put my $35 plastic hose balancer against any on the market cause how accurate do you really need to be. (and I've checked it against $200 gages) How many of you have put a fuel ratio analyzer on their bikes. Almost no one. These bikes are so smooth vs a Vtwin, is that an issue you need to get it down to a knat's hair? Ya, I should have kept my mouth shut.

Larry That is exactly where I am Larry and what I use,, I really like that set - it has all the adapters and came in very handy when building inline 4 chops a number of years ago.. Have done a variety of bikes - just did a 79 Wing for a buddy.. For the price, very well made! The most accurate and relied on by long experienced motorcycle mechanics/tuners is the mercury manometer type. There is simply no substitute for their sensitivity and accuracy. -Pete, in Tacoma WA USA Nothing steadier thats for sure.. I did own a "Twin Max" electronic balancer for while (got stolen) and it was amazing how accurate it was and was a joy to work with - talk about as close to perfect as possible.. The only problem was, you could only dial in two at a time - not a big deal on the Yam but other intake designs = not practical.. Not sure if TwinMax now offers a 4 cyl model now or not..
djh3 Posted September 30, 2014 #12 Posted September 30, 2014 I bought a Sync Pro off a member here. He had built the home made job with the clear tubing and ATF I think is what he used. I cleaned it up (the fluid init was about all dried up) and I use 2 stroke oil in it. works good for me. The mercury jobs worked really well and were smooth, but due to the mercury in them you have to be careful when you rev the bike and also some states will not allow you to buy or ship the chemical to their states.
ACE50 Posted September 30, 2014 #13 Posted September 30, 2014 That's what I like about mine, no fluid, nothing to get sucked in and so durable I could throw it on the concrete all day long and it wouldn't hurt it.
BlueSky Posted October 1, 2014 #14 Posted October 1, 2014 If all 4 gauges are calibrated to read exactly the same and stay in calibration, the gauges should work great. But the manometer types four columns will always read the same.

yamagrl Posted October 1, 2014 #17 Posted October 1, 2014 Will do. Just ordered the carbtune. Anybody know which carb is the master? Or does it matter with the carbtune. Is there any calibration process for them? #2 would be considered the master. You will sync as follows: First: Carb 1 to Carb 2 Next: Carb 3 to Carb 4 Last: Carb 4 to Carb 2 An easy way to remember is "Back carbs to front carbs, then right bank to left bank.
Broncoboy36081 Posted October 1, 2014 Author #18 Posted October 1, 2014 What can I expect realistically out of a carb sync as far as performance wise. I do have some vibration but mostly just at idle. Not like my old Harley vibration but enough I can see it in the antenna and trunk.

Not like my old Harley vibration but enough I can see it in the antenna and trunk. My Gen1 Mk2 idles so smooth you'd liken it to a sewing machine. Radio antenna absolutely still. When it no longer sounds like the sewing machine, it's time for another synch with my old 4 tube mercury manometer. -Pete, in Tacoma WA USA

So it would surprise me if they are even close.

Ok,, just going from memory here on my 1st Gens,, sitting on the bike, left rear is No. 1 and left front is No. 2, right rear is No. 3 and right front is No. 4.. No. 1 is master, No. 2 is set to No. 1, No. 3 is set to No. 2, No. 4 is set to No. 3 Never owned a 2nd Gen or worked on one,, are the carbs linked that much differently or am I having another oltimers attack here?

From one old timer to another, you are indeed having an attack of geezeritus..... go sit and have a cold beer as Yammagirl is correct.....and she's prolly got the manual open in front of her. -Pete, in Tacoma WA USA
