For what it's worth, the technical service bulletin says to adjust ON the side stand whereas previously the service manual said to perform the adjustment on a lift. From my understanding, there was accelerated wear on the guards (mostly because you ride with sag, not with the rear wheel in the air.)

I swear, half of this colossal thread is dedicated to chain tension. My method is to get onto the bike, with any gear I might be carrying and check for slack with the full weight of rider on board. It should be pretty obvious at this point if you are running too slack or too tight.

I'm at 13,000 kms and little swingarm guard wear.

I personally would never trust a chain tension measurement done with the bike unloaded: there are too many variables in play; rider weight, sag setting, sprocket size, etc.

+1

6 bikes in my garage , my chain tension measurment is " a little bit of slack when the suspension is compressed" no numbers , no rulers

16K on my WR , swapping wheels back and forth , one with a 42T and one with a 47

chain slider still about 60%

does anyone do an adventure/rally kit for the wr250r? something like this..



something with huge tanks, bit of wind protection, better headlight options etc..

I'm really trying to look at the practical side of this design, and not trying to be rude, but somehow this rally fairing business really takes away from the beauty of not only these bikes, but most bikes in general. I'm all for big tanks and better headlights (oh how I wish this bike came with a round headlight, big design mistake IMHO) but the beak is, well... maybe I'm just old fashioned. I am sure they are practical. But so were Pontiac Aztecs.
Unless it's stuffed with electronics, I am curious as to the benefits of the high er...nose. I have never been bothered by the air flow on this bike.

i guess beauty is in the eye of the beholder. I love the look of rally bikes. The rally ktm 690's for example look great.
However I'm not concerned about looks. But I am so overwhelmed by how versatile this bike is I think a rally kit would work great to make it even better for long journeys while still being off road worthy.

I swore I had a similar kit bookmarked at one point but it was on the opposite side of the pond and I remember correctly was going for 1500 usd. Of course I can't find it now.

This is the best write up of adjusting chain tension I've ever seen. A bit involved the 1st time, but after that its a cinch.

There is a guy that sells something somewhat similar, see post 72 of:

Well theres been all 08's, one with 1200 miles for 4k, one with 4000 miles and road rash for 3.8, and an x with 14k miles for 3.6. Those have been the only ones in the area for 2 months or so

For wind protection (adjustable screen),headlight options and a big dashboard, there is the lynx fairing. Not used it by myself (but considering it), but some on this megathread did:

You still have to find a bigger tank after that.

Thanks for that link, I have seen that TSB (imo written to sell special tools LOL). Its apparent from the various WR sites/threads those that have followed it still experience accelerated chain/slider/swingarm wear (and led me to research the root cause and find an alternative method).

By adjusting the chain tension at the tightest possible position it can ever physically be in through its entire travel (i.e. with front sprocket, swingarm pivot, rear axle all in a line), you guarantee the chain will never be too tight at any other point in suspension travel. No special tools are needed, its non-bike specific, it doesn't matter if the chain is adjusted on the sidestand or a lift or floating in space; rider weight, rider sag, sprocket sizes etcetera are all non-factors.

Those who are adjusting by sitting on the bike all geared up and adjusting chain tension at that variable sag point, and experiencing excellent service life, are IMO either:
1) Able to ride in a manner that rarely exercises the rear suspension to the point of maximum chain tension on a regular basis
2) Just plain lucky their riding weight gets the front sprocket, swingarm pivot point, and rear axle in a straight line before adjusting chain tension

To illustrate, I am 220 lbs/100kg, and all geared up I have about 4" rider sag. This is not enough sag to get the swingarm up to the point of maximum chain tension. Hmmm next time I adjust the chain I will measure and report the exact sag required to get the three points in a row .

I only landed one by checking this site once or twice a day, and not wasting any time when the right one showed up.

1200 miles for 4k sounds pretty great to me.
