my ball joint fell out the spindle does that mean balljoints trash? i havent tore it down yet. now where can i get ball joints and do they come out of the a arms? now last question will 1990 aarms fit 87? thanks in advance.

 

Yes the ball joints come out of the a-arms, yes 90 a-arms will work on an 87.

They attach to the spindles via a clamping collar and one falling out doesn't mean its trash, you may just have to tighten the collar. Now if the 2 parts of the ball joint itself came apart then it def. is trash.

 

thanks for speedy reply. was kinda wondering myself if the bolt on the collar came out. ill know tommorrow. ok one more question ive put like 30 hours on my total rebuild and i have a hellof a piston slap im mean loud what could cause this bad bore job? im really mad and doing that the ball joint and all my chassis bearings tommorow.

 

Piston slap on a 30 hour top end can mean (as you were thinking) bad bore, bad wrist pin, bad wrist pin bearing, or even bad lowerend bearing. Id pull the cylinder since tope end gasket kits are cheap and check the piston skirt for wear... oh and also if your bridge wasn't relieved after the bore job this could be snaging a ring.

 

thanks alot and 30 hours on complete rebuild im gonna find exactly what it is tomm. thanks again

 

what is this about relieving the bridge, I am having my bore job done right now

 

i think its where they kinda taper it to take the sharp edge off from the new cut bore. if thats not it tell me what to look for tomorrow.

 

At least you got a new swingarm bolt, making it easier to get your motor out this time.

bummer dude, maybe chattered bore, happened to my atc 250r.

 

i know what relieving the bridge is. ON your exhaust port,there is a little bridge that comes down the middle so your rings cant go into the exhaust port,like a little bridge over your exhaust port.well,since that is the hottest part of the cylinder during operation,that little spline will expand and push against the piston. your suposed to file or sand that bridge down a couple of thousandths,im not sure exactly how much but when my mechanic did mine it took like 1 minute to do and he didnt even charge me.This is not an optional preventative maintenance thing,its very very necessry. i wouldnt ever put a top end on withouth having that done.
YOU have to do that sharp edge removing thing too.

 

BE CAREFUL!!!! This happened to me a while back. I thought nothing of it, but it back together, tightened it up good and went riding. A couple hours into the ride the ball joint came out again except this time I was goin pretty fast. The A-arm hit the ground and the bike flipped sending me over the bars. Bent the A-arm and the frame plus I was in pain for for a week. Get a new ball joint and screw from Suzuki, it'll cost about 40 bucks but could save you alot more.
