The method specifies is the more exact method to use but does requiring pulling the shock to get an initial reading. Now ride your bike on a set course, for a set length of time and try to maintain a set amount of throttle 'aggressiveness'. Heck to make the test more obvious set it to 6mm, thats within Yamaha specs.
CHAIN SLACK TOOL MANUAL
Your chain will be plenty loose if you use that method with the stock set up. With your bike 'cold' from sitting overnight, set your chain slack to the manual specs of 5-15mm. The 790 method specifies having the weight of the bike on the swingarm with it and the tire in the air so the tire can rotate and not give a false reading.Īdjust chain so that the distance (gap) between the top of the chain and the bottom of the swingarm is 5mm with the chain being pushed upwards towards the bottom of the swingarm at a point 25mm (an inch) behind the chain slider. KTM 790 instructions are not using that method at all. Some manufacturers specify the amount of total defection in the chain (1.25" to 2" whatever). The BPA-Racing Slack Setter Tool grants an easier, quicker and more precise adjustment of the slack for all types of motorcycles Standard, Caf Racer. My 350, 540, and 950 need a 3-finger gap for correct tension, while the 790, with 270mm travel, needs a 2-finger gap on the underside of the swingarm.Ĭlick to expand.I think your mixing chain slack instructions from other bikes with the ones in the manual which are different. I prefer to measure by pulling the chain away from the swingarm at a particular point, as opposed to the method in the owner's manual, where you push the chain against the swingarm. After re-installing the shock and wheel, you can now use whatever metric you prefer to note the correct chain tension for the bike. (1) Position your bike so the rear wheel is off the ground (2) Position the tool at the back of the chain slider. At this point, the chain will be at it's tightest tension, so I adjust it to about 10-15mm of play. Remixed for a 2010 KTM 65 SX From brnoffroad For early model KTM dirt bikes with 5mm to 8mm of chain slack, measured from the bottom of the swingarm. Remove the rear shock, re-install the rear wheel, and block up the rear wheel so that the centerlines of the countershaft sprocket, the swingarm pivot, and the rear wheel axle are lined up in a straight line.
Since correct chain tension is an important setting, affecting drivetrain lifespan and even suspension performance, I always determine the optimal tension for each of my bikes in the same way. Since there are 3 main suspension travel options, (200/240/270mm), there will be different specs for each model. Any sidestand or paddock stand simply has too much variance, depending on what kind of load or shock preload each bike has. The best way to set chain tension is to have the bike on a lift or centerstand, so the rear wheel is unweighted. The BPA Chain Adjuster Tool, helps eliminate guesswork and achieve top precision for your chain slack every single time.
There is another thread about this subject, so here is my post from that thread.
