exhaust question

[micktodd]

Here goes im building two bikes 

1, 1977 gs 750 with gsx750 engine 

2 1989 gsx750es  with a gsxr750 slabby engine 

Any suggestion on what headers will fit any advice welcome  cheers mick

Is the gsx750 engine that you're putting in the gs is it a oil cooled or air cooled motor?

As to your question, what you looking for?

Any of the 750 oil cooled heads will go on (depending on how far back you put a oil cooled motor in a gs frame)

The b6 and gsx600f will fit the 750 gsxf/gsxr motors.

The b12 and gsxr/gsxf 1100 will also fit but they are a bit longer in the down pipes.

The only thing you mite find, is you may need to swop sumps, but if you do make sure you change the oil pick up to suit the sump 

Looking forward to seeing the project builds on these

gsx engine is oil cooled , the gs started out as just a frame lol  and gsx was cobbled together with bits missing  gonna be fun to build had about 5 different front ends on so far

Have you seen @370stevegs1157 and his miss gs600  may give you good ideas both very nice bikes.

You need to start a build thread in the projects pages

yes read through his build nice bike some trick bits on it as well looks spot on my trouble is like bits on other bikes so lot trial and error like with the gsx not keen on the tank so looking for something different

Since you asked - here's my two-penneth!

I put a 1200EFE engine in my GS frame and I realised that the engine sat much closer to the front of the cradle than the original engine had. In many ways this is a good thing, but depending on the exact angle and the mounts you use, it may throw up a few interesting alignment issues.

So in the pics attached you'll see what I mean: the EFE engine sits maybe an inch an a half closer to the frame.

Cheers for that Jonny  im ditching the gsx750 engine for the gs.  Going to get another gsxr750 and put that in when can sort the mounting plates out keep getting the wrong ones.

Even the ones i bought for the gs dont fit

What happened to your GS's cylinder head?

That wasn't mine. It was taken at Exhaust Craft when Dave was making my headers up. I just used it as reference.

I guess it just makes it easier to get in and out of the frame.
