thank you all for this valuable info. It will serve for years I'm sure.

i have a question regarding the syncing of the carbs. I've elevated my tank and extended the fuel line. the vacuum line to carb 1 was removed. air lock and no gas flow is what happened.

I assume that i can bypass this situation by extending the vacuum line and place a Y junction in there for the mercury line, keeping the line attached to the fuel petcock as well.

anyone see any problem with this? Clymer's and the shop guide say to just disconnect the fuel, they don't address keeping the tank attached.

thanks a billion

 

Yes, you could use a "Y" fitting to enable the vacuum to reach both your gauge and the tank. Alternatively, you could substitute your tank for a simpler, non-vacuum operated tank and connect your vacuum gauge directly to the cylinder. Personally I use a small plastic oil can with a fuel line attached; this way I can remove the tank completely while troubleshooting and have more room to work.

Another choice would be to use your regular tank but leave it unhooked (therefore not needing the y-fitting) and simply suck on the vacuum line every few minutes to keep the carb bowls full.

 

Sorry for the Bump but i'm trying to do this right now and I can't get the carbs off. I'm using all my force to rock these things off now anzd it's not budging. Any suggestions?

 

Good Luck man.. its not really luck though. Just patience

 

Does bike run now? If so, run it til it gets to operating temp. or use a hair dryer to heat the boots (insulators). They come off way easier if the boots are warm.

 

I got them off. The bike does not run, but, it's all good. I tied a shoe string around them and pulled real hard and they came right off. haha.

 

Yeah, if the carbs haven't been removed in a long time, the boots tend to stick. :/ Heat helps

 

Oh God; dad's back! Everybody hide!!

 

lol

 

the Y works wonders, now I have a very quick setup to repeat when needed. thank you
