Hi, I had to adjust chain slack again on my 2018 GSX-S 750. This bike seems almost impossible to keep the swingarm tick marks the same on. I use an 8mm Allen key between the sprocket & chain to pull the wheel forward and make sure axle is up against the adjuster blocks. I turn adjuster bolts the exact same on each side (ex. quarter turn on left side then right side). All said and done the right side is off 1cm from the left side per the swingarm tick marks. Will that even make a difference?

It would be nice if the ticks had numbering. I was off by probably a cm or so and the bike pulled noticeably in straight lines. My tires were cooked when that happened so that may have had something to do with it as well. I have luck now by forcing the tire forward with a gentle, bottom of the shoe kick when making adjustments before cranking her down.
You could measure differently instead of using the ticks. Perhaps use a tape measure to do the distance from the axle to a center point on the swing arm? I'm probably not explaining that well but I have heard of doing that before.
If you're off at all it will certainly cause uneven wear and the bike may not track straight down the road. I can take my hands off the bars and any 'reasonable' speed and it tracks straight and I don't seem to have to put any more or less pressure on one side of the handlebars.
I really don't like the "ticks" either, perhaps there is an aftermarket solution that would replace those blocks.
keep the axle nut snug so your pulling against some tesion with the allen adjusters. If unhappy with position loosen axle nut and allen adjusters a lot, kick wheel forward and start over again. I wear readers and flop around on shop floor on my back, makes for a nice clean area
