Then I will go get some fresh premium tomorrow morning. What would you recommend 91 or 93? Does it matter???

DONT DO ANYTHING ELSE. Fix the problem first, you dont want to be chasing problems created by fixes that you create after the fact. Drain the gas, add fresh gas and go from there.

Yes, arizona iced tea bottles work just as well. Because they are glass and dont distort or expand under vaccum or pressure.

Its real simple, on the bottom of each carb is a vaccum fitting.

Stuff needed:

1. two solid glass bottles with a wide mouth top (sobe or arizona iced tea bottles work great

2. two Rubber stops (found in the nuts and bolt isle of home depot or lowes) that fit in the bottle opening

3. a few feet of hose.

4. old oil/trans fluid, basically a fairly thick and heavy liquid


How to build the sync tool:

1. drill 2 holes in each of the rubber stops so that the tubes fits in there very tight, you really need to make sure that it is a good seal between the tube and rubber stops

2. Fill the bottles with oil 1/3 way in each bottle

3. One tube needs to connect the two bottles, this tube needs to be long enough that it reaches and sits on the bottom of each bottle, it also needs to be equal length

4. Put another tube in the rubber stop, and it needs to sit just bellow the bottom of the rubber stop. These two tubes must also be equal length, and long enough to reach the carbs from wherever you are working from, the shorter the better.

5. shove the rubber stops in the bottle top

6. Test by sucking fluid from one bottle to the other and visa versa

7. It should look like this:




How to sync your carbs:

1. Connect each of the tubes from the sync tool to the carbs vaccum fitting (probably on the bottom). One should be going to the fuel petcock, the other should be capped.

2. Start the bike

*watch the bottles very carefully to make sure that the oil isnt sucked into one bottle then straight into the carb. This shouldnt be possible since each bottle is only 1/3 full and the tube leading to the carb should have plenty of wiggle room before it touches the oil if both bottles drain into one.

3. Adjust the carbs until the fluid levels out between the two bottles.

*make small adjustments, the last time I sync'd carbs 1/2 turn of the screw would empty the bottle in a few seconds. Start with 1/16 turns and adjust as necessary

4. If the bike remains running with both bottles evenly filled with fluid then you have a pair of sync'd carbs. Also this isn't rocket science, close is good enough.

Edit: This is what it looked like when I did it
