I'd stay away from fitting any sliders etc to the head's sides. It's way too delicate and you'd probably damage the head severely even in a relatively light crash. Just my two cents, Nik

Very nice!

I have 4.5"/160 on two slabbies (7/11s) and 5.5"/180 on two slabbies (7/11s). The 5.5" looks better but the 4.5" handles better and is more fun to run.

The top pair is for a post-85 slabbie. The bottom pair is, I guess, for a slingshot.

They screw straight into the bracket. It's appr. 5 mm thick.

☺ There were many minor differencies that few remember.

In 1985, there wasn't an additional bracket at the mount underneath the engine. The belly fairings screws straight into the engine bracket.

Rubber bushing #23 bolts to the head (to the bolts fitted in the holes through which you slide in the rocker arm axles). The lower fairing is held by screw #35, which is screwed into the side/bottom engine bracket, #5 on http://www.robinsonsfoundry.co.uk/shop/online-store/suzuki-parts-finder/gsx-r/gsx-r750/f-g-h-1985-1987.htm#!gsxr750fghframe

Note that the 1990 750 L frame is very different from the 1991 750 M frame. The M frame is 15 kg or so heavier (probably a cost-saving move where Suzuki used the same frame on 750 and 1100 in 1991). J/K frames are smaller but will house an 1100/1200 Engine.

My experience, after dozens of slabbies through the years: Slabbies had either the small/flat 5 gallon tank (as seen on R1guy's, banoffee's and Swiss Toni's photos above) or the taller 5.5 gallon tank (as seen on CockneyRick's photo above). Many (most?) markets got the small tanks in 1985 AND 1986, on both 750s and 1100s, but some markets, e.g. the U.K.and the U.S. got the taller 5.5 gallon tank in 1986 (not sure if it was implemented from the beginning of the model year or if it changed during 1986). Concerning fuel taps: 1985 tanks had a non-vacuum tap, with narrow spacing between the tap holes.1986 and 1987 tanks (750s and 1100s) all had vacuum taps (which were larger) with bigger spacing between the holes. Location of the vacuum taps may be different between 750s and 1100s.

Hi all, I've gathered manuals, magazine excerpts, guides etc over the years. Perhaps it's useful for you lot too. Download what you want from my OneDrive https://1drv.ms/f/s!Ash8W0PWWm5qoWkav2N35FE8dskux

My original Swedish 1985 has a flat top. It was replaced in 1986 with new original tank from Suzuki and this tank was also flat. However, my mate's original 1986 has the elevated section around the filler. I have another 1986 tank without the elevated section. There seem to be no logic around this.

That info is not correct for the slabbie CDIs. The rev limit on an 1100 slabbie was roughly 10,500 rpm, and the 750s were 11,000.
