yeah it shoudl have some play, but either way if its stock it will go out sometime

 

And you guys say that the Raptor has problems???

 

not a good thing to say in here x250rdude

 

No,it just goes to show,that you can not satisfy everbody.Every great machine will have its critics.The DS has its flaws,just like every other quad(fans,chain rollers).The quadzilla 500 would vibrate bad.The Ex under some situations will crack swing arms,and what about those lousy shocks on the Kawasaki Tecate's .Yamaha has their quirks,and even the R had a flaw or two,But I can not believe you guys have bent an a-arm on the DS.You must have really been abusing that thing. I have riden my EX over some pretty scary pits,and had some worst landings with my big butt,with out bending anything,and if my EX can,I know my DS can.Go figure.......

 

Just to let you guys know,I do like my DS a lot.But as for everything I do turns out bad. I have three buddies and they haven"t had a problem with there bikes yet.Also has any one had problems with there bike back firing? Mine does it all the time.The shop never can find out what is causing the problem. Still would not trade the DS for any other bike.Just to much fun.Shop has new A/Arms in but can"t install they have to order some part that is suppose to be an upgrade item. Thanks for the replies!

 

Yes I have had the backfiring problem. In my case it turned out to be because the incompetent "tech" at the dealership setup my cam timing one tooth off on the exhaust side. In that situation it caused a loss of compression, 120, and backfiring through the exhaust.

In your case, if the timing chain hasn't been touched, and you haven't changed jetting or air filter/pipe, it is most likely a valve adjustment issue. When the valves wear on this style of motor they have a tendency to seat deeper in the seats, making them effectively longer and reducing clearance on the camshaft. Check your valve clearance on the intake side, rear bank, it should be .004" - .006" cold.
