My LT3 petcock needs everything new. It's real messed up.
I can buy all new oem parts for it but it will cost me over 60 bucks.
I can buy a aftermarket replacement for about 20 bucks. I haven't had the greatest luck doing it either way. Leaning towards rebuilding.
What are you guys doing?
gotta watch the aftermarket ones. is it a 16mm thread or flange mount?

Pipe style with a double threaded seal nut.
probably a 16mm then . ive had decent luck w the aftermarket ones for cb 350s etc on the smaller bikes like the yl1 & ls2. you order them dir a yamaha and its 2x the money.. but its the same part. these are dual outlet though
This is the one
LT3
possible to post a picture of it? I have a couple new aftermarket ones here I bought hoping it might work on some of my dirt bikes but didn't pan out (win some, lose some, etc).
They never got mounted or ran gas through them.
yup a 16mm thread. common size. id replace it.
