Carb Sync Tool
So, with the bike apart for the front end swap, I'm gonna do some of the important stuff before riding season.
I did a search of the web for Sync Tools. Found this one: http://faq.ninja250.org/wiki/How_do_...carburetors%3F Lots of pictures and good explanations of how they did it. Might try the 2 bottle method. This might need to be moved and stickied for everyone's use?? |
I used the yardstick & tubes method, easy as pie.
FYI, several other similar threads - Carb Synch Tool Search |
yardstick method has worked well for me too.

I believe the yard stick is the way to go if your looking to do it cheaply. Worked well for me many times. But I recently invested in the Motion Pro sync tool, very similar to the carbtune posted above.

So the next logical question is did you notice if the yardstick was inaccurate?:confused: |
As long as you get all of your air bubbles out, it's just as accurate as anything else. You're not trying to measure specific vacuum readings, you're trying to see if the vacuum from the two carbs is the same. So, if the liquid in the tubes (I used red Caterpillar coolant) rises at the same rate on both sides of the tube, you're good.
|
I use the yardstick set up, I was just wondering why the purchase of the sync tool? Is there something he noticed? we missed?
|
I just took the time to read the bottle method and I will be making one of those next. thanks for the info.

I also use one of these tools to adjust the carbs with. http://www.motorcyclecarbs.com/kl/catalog/2003/069.pdf |

Anyone ever use gas instead of oil or antifreeze for the yardstick method? It seems like it would be much easier to get rid of the bubbles.
|
I think gas would deteriorate the clear hose (and using black fuel line hose would defeat the purpose of the gauge) and would kinda stink. I used A/F because I had it on my shelf and it was red (easy to read).
|
Ok, I thought the change would be easier to notice. If the oil is being sucked away from the carb you are adjusting, should you open the carb (throttle valve) up more or close it?
|
There's only one adjustment screw on the VTR carbs, so you want to adjust it whichever way levels out the fluid (with the ruler method anyway).
|
I understand that but it is not as noticable I expected. If I know which way to adjust then I can be sure I'm am not adjusting the wrong way and further out of sync.
|
Rotating the screw clockwise will give the rear cylinder more vacuum, raising the fluid level for that cylinder.
