GS1150 cylinder studs

Recommended Posts

I'm trying to confirm the locations of the different length cylinder studs on the GS1150. I have the factory manual, however they don't remove them from the engine case. I scoured the Internet and was unable to find much information on the topic. I was however able to use the parts diagrams and information from various companies globally to create a diagram.

 

There seems to be an early and late variant of the cylinder studs. Can anyone verify that what I've come up with is correct?

 

Thx kbbeckius

If you can find a decent parts fiche ( the ones on Alpha Sports are bad for this) - each stud is identified length and position.

Just to muddy the waters - when changing to HD studs - they are one length, all 176mm ! Makes things considerably easier !

Look at your head, you should be able to see where the short one, and where the long ones go.

Ok, sorry....I read the rules and introduced myself in the general area, my bad...

I made the diagram based on parts diagrams found online, some are such bad scans that you can't read the numbers, also many websites won't show the required number of each stud because they are discontinued. I have ordered an original Suzuki parts microfiche off Eblag.

I have the aftermarket studs from APE and they are different lengths, and I also measured the head and the only location that appears to be different are the ones with the dowels, marked "5" in my diagram, which need the long studs.

 

Thx kbbeckius

As Reinhoud says,  'Look at your head'. Fit your studs into the case where your think they should go. Fit head & barrels, and see how much thread shows  through the head. you need a nut snugged down, showing maybe 2-3 threads. Allow for gaskets. Swap round until it's right!

You can see on the head itself where the short and long ones go.
