| Chain Tension | |

| How tight do you run your chain? The specification seems very | |
| tight to me. | |

| I have mine about 3/4 inch to the slide guard. The manual says | |
| 1.8 inches, but that didn't look right to me. I have yet to | |
| talk to a KTM expert about it. | |

| I run mine fairly tight. The older the chain the quicker it | |
| starts slopping around. If I went back to more offroad riding | |
| I'd probably loosen it. But as for now doing the whole street | |
| thing predominantly, I'll stay with a tight chain. | |

| Here's my $.02 | |
| Ideally what you want to do is check the tension with the | |
| counter-shaft, swing-arm pivot bolt and axle in syzygy (i.e. a | |
| straight line). In this position you should have a small amount | |
| of play 1/2" or so. This will be the point at which your chain | |
| will be the tightest. This is the point that a tight chain will | |
| cause problems. | |
| When I was changing the spring on my rear KLR shock I lined up | |
| the swing-arm while I had the shock out. I then adjusted the | |
| chain to the tension I was ok with. After putting the bike back | |
| together and setting the sag I then checked the chain tension on | |
| the side stand as per the manual. It was definitely looser than | |
| recommended. | |
| I'm not saying this will be the case with the 690 but until | |
| someone checks it at syzygy I will be running mine a bit loose. | |
| I have a few parts coming in this week so if it doesn't look to | |
| hard I'll do it and let you guys know how it turns out. | |

| Hi Guys, | |
| It's always interesting deciphering European manuals, isn't it? | |
| My 2 cents, at 30 mm back from underside chain guard, push chain | |
| up and it should almost touch (.2"?) the swing arm. On a new | |
| chain, it's less important to rotate the rear wheel and check | |
| multiple locations, but you might as well develop good habits | |
| from the start. | |
| My issue is that the factory chain has no master link. That's | |
| got to be changed. | |

| Aloha 690 Enduro Forum, this is my first post here: | |
| I've got a fairly new Husky 701E and now after lowering it with | |
| a Koubalink(-1.25"), chopping the sidestand(-2.5") and setting | |
| up a heavier shock spring(110) Of course, now I need to tension | |
| the chain. I too, thought the factory spec. (.20") was very, | |
| very tight. I think that they could only be imagining a bike in | |
| a pristine showroom, delivery state. The assumption that your | |
| counter balancer, swingarm and rear axle will be in alignment | |
| whilst the bike sits on its sidestand could only be accurate on | |
| a new, unmodified bike. Any changes to preload,tires, sidestand, | |
| spring or cargo would throw their basic assumptions out the | |
| window. | |
| [list] | |
| [li] The danger in operating your bike with too much tension is | |
| that you destroy the chain, sprockets and the counter balancer | |
| bearings...perhaps more. The cost to repair this would be | |
| $500-$5000. | |
| The danger in operating your chain too loose, assuming not | |
| ridiculously loose, is that you prematurely wear out some | |
| plastic guards that were meant to be worn out. Cost | |
| $30-$100[/li] | |
| [li][/li] | |
| [/list] | |
| I intend to reestablish the correct tension as follows. Assuming | |
| that KTM's idea behind the .20" slack was that the balancer, | |
| swing arm and axle would all be in a direct line; I will use a | |
| ratchet strap and make crank it until those elements are | |
| directly aligned. Then I'll adjust the chain as directed by the | |
| manual. After that I'll release the strap resting on the side | |
| stand and I'll measure the chain deflection at the prescribed | |
| point with my caliper. This new number will become my setting | |
| for my bike as it is actually modified, equipped and adjusted. | |
| I am new in here and I would like to hear what you old timers | |
| think about this logic. Mahalo | |

| Pasomonte, check out the Youtube channel for Slavens Racing. He | |
| has a good video on chain tension. If you are going to change | |
| your shock spring, you can take care of both at the same time. | |
