Topic: CB500T tank on 74 cb550 what petcock you running?

[1974cb550k]

Just wondering what you guys were running for petcocks on a cb500t tank when put on a cb550. I moved the half circle mounts back 1/4 in on the front of the tank to make room for the clip ons. It then put the petcock bung directly over the #1 carb. I ended up using a cb400f petcock with slight modifactions. The prob is that it has a single feed. It needs to be short and have a dual vertical feed.  Thanx

I have a cb500t tank on my cb550 and I use the standard twin outlet petcock, however what I did to clear the number 1 carb was to turn the petcock about 1/4 of a turn and it slotted in between the carb hardware.

The stock petcock (550) was hitting on the top of the carb. When turned does it set down between carbs? We talkin stock cb 500t ot bc550 petcock? Got a pic? thanx

Here you go, I remember I had to raise the rear of the tank about 1/4" also.

Here you can see the standard 500t petcock has been rotated slightly..



Here you can see how much I raised the rear of the tank...



Now the gas pipes snake up through the horizontal bars on the carbs to join the twin outlet, I am using a t-connector as I only need 1 inlet for my carbs.
