I'm having some more issues with my 250. I installed new swingarm bearings, new cushion lever bearings and a brand new axle carrier. I did some serious (and hard) riding on Saturday and had some issues with the swingarm.

Here's what happened:

After about 30 minutes on a local MX course, I went back to my truck to make sure everything was OK. What I found was that the chain adjustment indicators were off. The left side seemed to be "pulling" closer towards the front of the bike while the other side remained in its original location. After adjusting them again, I went back out and had the same results. Anyone ever had this experience? Everything else seems to be inline. The swingarm doesn't look bent with a visual inspection.

Any help would be appreciated as usual!

 

no its just the chain pulling the bearing carrier twards the front sprocket and it totally normal

 

torque the four carrier bolts down good, then tighting up the adjusters...

 

Really? Normal? That doesn't seem right. I certainly believe you but that's just weird!

Believe me, I've torqued those things down something serious and they still moved...

 

No man, it's not bent, just normal stock swingarm junk! Do yourself a huge favor and toss the stocker and get a round housing steel swingarm if you ride MX. It's a little costly but is well worth it and will cure the chain adjustment problems and won't crack as easily as the factory turd. I have cracked EVERY one of my Quadracers swingarms and I have owned 3 of them. I have also experienced the same problem you are having. Not only is it a pain, but it is unsafe as well. You can and will throw the chain eventually after landing a big jump causing your rear wheels to lock up and possibly causing a crash and possible damage to your quad......trust me on this!
The carrier will continue to shift and continue to loosen. You wil probably end up breaking the backup bolts and aluminum plate on the back of the swingarm as well.

 

o.k. if you dont have the money for a round housing swingarm. get a big cheater bar on the end of your ratchit, and tork those bolts down i keeped haveing the same problem for a while. an then i just torked theme down with cheater bars never loosed again.good luck[img]i/expressions/face-icon-small-happy.gif[/img]

 

Well, I'll try the cheater bar first. The backup bolt on the left side is already bending, I'm sure it won't take much more.

Thanks guys!
