I am leaking fuel from the T on the fuel rail (right where the line connects) and it seems to be coming from the shorter side of it where it connects to the carb. looking at them from above it would be the left side of the T. so I thought, nothing to it, just replace the o-ring. did that, and it still leaks! is there a trick to getting the o-ring to seat right? I cant see any cracks. was doing fine, but I took out the carbs to replace the cct, now it leaks. ANY thoughts are appreciated, I really want the bike back on the road! season is winding down!!! HELP!

when installing the O ring, use an OEM O ring, and lubricate it with something such as motor oil to ease installation into the carb body. I suggest motor oil simply because it wont affect the carbs negatively when it comes in contact with fuel, most other substances I''ve no experience with.
other than this, I cant really think of anything, short of a crack in that T part that may be causing the leak.

Did you take the carbs apart at all? It sounds like your floats might be stuck or maybe a fuel stop valve needs to be replaced.

Actually, never mind. lol I was thinking of the other T for the carb overflow. What condition are the hoses in? The O-Ring could have folded up in the opening when you installed the T. You can get a small screw driver and try gently seating the O-Ring before installing the T.

i had this same problem. it turned out that the T (its called a joint), had dryrotted or something and was in bad shape right around where the o ring connects to the short end of the joint. I replaced it and the problem is solved. no more fuel leak and the bike runs great.

all good hints. I checket the joint, looks to be in good shape. I will try using some mystery oil to get the ring to seat well. if I cant get it to stop I will order a new joint and see what happens there. any other ideas? thanks a lot guys! dying to get it running again!!

did you have the carbs apart? Its possible there is corrosion inside the slot on the carb. check that and just take some sandpaper and stick er in there and twist it around, corrosion and rubber dont mix very well. That or are you sure the t is in there right? Mine did that when i reassembled them, but my t wasnt in correctly, I turned the t and it almost seemed to lock into place.

well I found the problem. it was a cracked fuel joint. all fixed! so I put the carbs back on, minus the air box and fire it up to test. it runs great and no leaks! well thats good, so I put it all back together and fire it up again to take it for a test run... no I have a loud clacking coming from somewhere up front. damndamndamndamn. now I will take abreak and maybe try again later. just my luck. oh and the noise I was trying to get rid of with the new cct is still there, in addition to the new noise. should have left well enough alone!

the clutch is noisy, but its not the noise I *WAS* hearing. I think it was a sticky valve or something... out of curiosity I poured some liquid magic down the carbs while it was running (marvel mystery oi ROCKS!!!) and it quieted right down. took it for a ride and it seemed to work itself right out and the motor is smoother than it has been since I have had it! amn I love that stuff! this winter I plan to redo the clutch and do a good set on the valves, just for peace of mind. checked the valves last year and they were withing tolerance. thanks for all the help guys, felt GREAT to have it back together, although I think the jetting needs to be more rich. seems to surge on the highway at 55 mph

well the noise came back, so I pulled it apart again and fattened up the jetting, thinking it was a knock. nope. so I changed out the new cct with th eold one. that fixed it. what would cause a new cct to make a racket and the old one not too?? my chain real stretched or something??

on the manual cct, how much adjustment did you put into it. could''ve been too tight or too loose. i run an oem unit because i didn''t want to bother with making adjustments every so many hundred miles. and i have had rather good luck with them.

if the oem adjuster is new then we''ll leave that alone.
what remains is cam chain and cam chain guides.
how many miles on cam chain? could be stretched and end of its service life.
or cam chain guides are worn and at the end of their service life.
or both are worn and/or stretched.

no idea the age of anything other than the new cct. all I know is that the new cct makes noise, the olod one does not, at least nothing as bad as the new one! the new one sounded terrible, like a bad bearing or stuck valve. why would that happen?? guess I am not sure of what was physically happening. thanks!
