how much play should you allow in the chain. mine seem to shift a lot nicer with the chain relatively tight. i bought an o-ring chain because the stock one kept stretching. spent 50 bucks, and the new one really isn't much better. am i running my chain to tight?

Maybe. Look in the manual and make sure you are adjusting it to spec.



It's normal to adjust the o-ring chain once or twice as it breaks in. If you keep having to adjust it often after that, you've got problems.

Hello hoofhearted529, so did you install new sprockets with the new chain? This is a necessity unless they are virtually / really really close to new. Like maybe less than 100 miles. Even that could be too much. The factory chain starts stretching / wearing immediately and wears the sprockets to match. Not good for a new o-ring chain .

Don't run it too tight. You will risk damage to the countershaft bearing and other parts.



Slack should be 30-40 mm (1.2 - 1.6 inches).

Owner's manual : 1.4" to 2.4" (35mm to 60mm)

Shop manual : 1.2" to 1.6" (30mm to 40mm)

Figure that one out!



With the top part of the chain taught, using the trailing edge of the piece of plastic from the chain guard that hangs below the swing arm, I have mine set at about 2.25" vertical slop.

People tell me it is to loose but if I go one notch tighter on the snail it is only about 1.2" and the rule is "a little loose is better than a little tight".



The tightest the chain gets is when the primary sprocket shaft, the swing arm shaft and the rear axle make a straight line. If there is a little slop when these three points align then I think you should be OK.



Fifty bucks for an o-ring chain sounds like a bargain. I paid $35 for a regular chain and have maintained it religiously. It has over 11K miles on it and looks in great shape. I did replace the sprockets with the chain so it was an entirely new package.



Good luck!

Tony....I know what you are seeing....the newer manuals(mine is an 09)says what you rounded up to...1.4---2.4". In the service manual,it also has the mid 80's specs.(I think they show the 87 and 88 models)..this is where folks are getting confused.Why Yamaha would change this?...they changed the hardware on the securing part of the rear wheel...re-read the service manual;through me for a loop also!.

Im also new here. I bought a 99' tw200 this past spring and put over 3000 miles since then. I've adjusted my chain several times and its to the point where I cant adjust it any tighter. Im assuming Ive stretched the chain and wore the sprockets. I have no idea what type of sprockets or chain I would need to replace it.

the stock chain on my TW only lasted 165 miles. it stretched till i had no more adjustment then when had to remove links for the second time i just got rid of it for safty reasons. i kept it at about 1.75"-2.00" of slack. now ive got a DID chain and a JT 47 tooth rear sprocket, set it at 2.00" of slack and have not made a single adjustment for 200 miles.

For stock gearing 14 tooth front and 50 tooth rear sprockets and a 122 link size 428 chain. Most here will recommend the o-ring style chain.



Definitely buy all 3 as a set.



Price and shipping change almost daily, so the best bet is Google search for prices, or check the prices on sites mentioned all over this forum.

Mine was 14 tooth. It's an '07.



What year is yours, and where did you buy it? New or Used?

Got my TW beginning of July. Put almost 2,500 miles on it. All is stock and I adjusted the chain only once. Tried yesterday to get it to the next notch ( #3 on the snake) but went back since it was too tight. Any reason that my stock chain doesn't stretch as much as all the other's members chains?

The Yamaha sprockets are very good quality. If you like the stock sprocket ratio, you can order sprockets from www.stadiumyamaha.com or many other online suppliers a lot cheaper than most dealers will sell the same parts over the counter. Google yamaha motorcycle parts. You'll also want to order the three bolt retainers and a side cover gasket in case you need them.



93823-14149-00 SPROCKET, DRIVE (14T) $10.61

15A-25450-20-00 SPROCKET, DRIVEN (50T)$22.61

The above parts you will definately need.



90215-08160-00 WASHER, LOCK $2.92 (3 needed)

3AW-15451-03-00 GASKET, CRANKCASE COVER 1 $4.78

The above parts you'll maybe be able to reuse, but for $15 might as well have them on hand. Eventually you will need them.



You'll need size 428 chain, 122 links long, and a master link. I don't recommend the Yamaha replacement chain. You can buy a much better quality open chain for the same money elsewhere. A higher quality open chain will still require cleaning and lubing on a near daily basis.



For long life and reduced maintenance requirements I like o-ring chains. Google 428 o-ring chain. RK, EK, and DID are three brands that provide a quality o-ring chain. Expect to pay from $70 to $100+ with shipping. Money well spent considering the hassle of swapping sprockets on a TW, and the hours saved on not having to do chain maintenance you won't be doing over the next 25,000 miles. All an o-ring chain needs is washing the dirt off with a water house and a squirt of something to prevent rust every now and then. Nothing unusual to go 5000 miles or more between adjustments.
