I am getting a clanging noise at idle and kind of rattle at speed. Still a fresh top end and they said they checked clearances and they were good. Only mechanical thing I can think of is maybe counterbalancer bearings??? Waiting for this video to upload. How noisy are these engines?
It's boggy today too, but it's ~80F and humid AF, so I'm guessing the humidity is why it's running rich?

When i was at TF, a lot of them had the same rattle-y noise mine did.Originally Posted by loganm
one guy said his made the same noise before his main bearings went. I know my kick starter rattles a bit.

Kicker rattles but holding it makes no difference. I know it's gonna make some noise, there's an explosion going on in the cylinder multiple times a second. The clanging doesn't make sense. If it were pinging wouldn't that be more under load? It goes away after idle and turns into a rattly noise. It's still a fresh piston so unless they bored it wrong and lied to me about it I have no idea.

Only thing I can think of is main bearings and a bad crank. When I took apart my first 250R, one bearing was completely out and the other was bad by a small amount. Rod specs I believe are .026 or .028-.032. Mine was at .034. My other 250r has the same noise. The engines are generally loud from what I've been told. I would check rod clearance.

Crank and rod bearings are good, spin smooth, no play. Top end looks like pictures previously posted... Wtf!!! Should I call them out on this? Kinda really annoyed rn.

OK bud.. who's doing your work? Might be time to get a new, quality place for your repairs...
I doubt, if you took it back apart to check out the bearings / etc will they do anything for you now... Maybe they will... IDK.
If it were me, and it was making all the racket you were describing, I would have brought it back to them running and had them listen to it. If they would have told you "it's normal", get it in writing and hold them to it. If they won't stand behind their work, then obviously you need a new place.

Well, I don't have to tell them I've taken it apart... I'm gonna call them tomorrow and not mention that, and I'll see what they say. If it fries another piston I'll send it to someone here or Allen knowles since he did my crank.

Also, it doesn't look like the piston ever came in contact with the bore. It has some light scratches on the intake and exhaust side, the kinda light scratches you get when you run the piston through the bore dry because you're curious what .020" actually looks like in the bore (compared to the old piston).
Only other thing could be my air filter is just a POS. I cleaned and piled it with the k&n stuff, but it came with the bike so idk.

If anyone was wondering I sold it a long time ago. Most likely my issues were related to running a straight air filter with no airbox.
Anyways don’t own a trike anymore, dabbled in drugs, mental illness, and a toxic relationship with someone as insane as me for a while. Now have a 97 kx250 I’m building and a 18 yz 250 that is my main. Trying to go race motocross, I mostly ride at bar2bar. I will probably never log on again feel free to delete this account.
