I dont know if this has ever been brought up before in this forum, but the chain slack is adjusted midway between the front and rear sprockets. Pretty obvious. But what isnt obvious, and is not shown in the factory Suzuki Service Manual for my '14 DL1K, is that there is a casting boss on the underside of the swingarm in that very location, presumably for that very purpose. This boss is less than a 1/16th of an inch thick, has 3 straight sides and one rounded side closest to the wheel. I measured 27" between the drive and driven sprockets, and at 13.5" is the boss. I do not know if there is a similar boss on the 650 models, but it's worth a look-see. Similarly, my ZRX1100 has a cast-in triangle midway between the sprockets.
I did get a chance to use my Motion-Pro Sprocket Jammer, and itworked like a charm. Loosened the adjuster locknuts, turned both of them in equally then tightened the locknuts. Placed the Jammer between the lower chain run and rear sprocket, loosened the axle nut, rotated the wheel forward which pushed the axle blocks against the adjuster bolt heads, torqued the axle nut and DONE. I have it set at the slack I want, and alignment was right on the beam checked with my Sims & Rohm(Muzzy) chain/swingarm aligner.
