1983 gs 750 ?

[Guest]

I was wondering if anyone has a 1977 gs 750 handy.I was told the head port size is the same as a 1985 gs 700.I was told by a fellow he put his megaphone from his 77 gs 750 on his 85 gs700.The gs 700 is pretty much the same motor as my 83 gs 750.I need to know the port size of the head and the spacing?.

Thanks.

Not the same at all. Spacing might be the same but diameter is smaller on the '83 730 and '85 700. The older 750's have the same diameter as the liter class bikes. He would have had to grind down the pipes to make it fit the 700 head.

How much are you looking to spend? You can get a new Hindle meant for '85-'87 GSX-R750s that will fit. It's only the header and midpipe so you have to buy a can as well. They have them on closeout for $299. They are usually $600 or more. Just about any exhaust meant for the oil cooled gixxers will work.

Thanks for the info..I have a header and can already off of a 86 gsxr.I was looking to put a vance on my bike.I like the sound and look.I have a kerker can on it now.I am looking for a deeper sound.I have tried repacking and it didn`t change.

Maybe it's just me but I've always thought the V&H systems had a little higher pitch than say a Kerker or Yosh.

Well my buddy has them on his kat's and they have a nice deep sound.Maybe that is the 1100 sound?.My buddy has a micron on his 750 and it sounds really nice and deep.They are way to much money tho.
