Title: Carb Sync
Post by: tykho on August 29, 2010, 02:21:23 AM
Just a quick q, in you guys' opinion, would it be very challenging for me to do my own carb sync the first time? I know I'm overdue for it, I'm at 10k miles now, am I gonna break anything if I wait longer, or should I just quit being lazy and get it done?

if you dont have guages it can be a bit tricky although you can get it pretty close by eye.
its not a very difficult job as long as valve clearances, idle and carbs are all good.

Yea, I did my valve clearances before, left em a little lose for the motor's sake. I think I'm gonna go ahead and give it a shot, I'd rather learn to do it myself anyway.

On another note, any of you guys who use sea foam have any comments on how clean it keeps your carbs? I run a 3rd of a bottle every 2000 miles or so, I haven't done shaZam! with my carbs yet as you've probably gathered, so I'm just curious if it's even worth it.

Eyeball synch is easy, take off carbs and look @ bright area of sky and adjust for same shaped crescent. Btter than vacuum.
BTW if the bike is vibrating a lot @ idle and jus tabove idle - synch it, else forget it, its not somehting that needs to be done ... unless you fook wiht it first.
Cool.

The idle adjust knob makes both open at the same rate.

Opposite the idle adjust, there's a philips or JIT screw.  Turning that makes one valve open more or less in relation to the other.

go back and forth with it, crescent one side, then the other, then slowly arrive at middle setting. You will be very close per the meter.
