Hello, I have another question for you guys. I decided to check my flywheel after I noticed the motor making a weird sound when it was at low rpms. So I took the cover off and grabbed hold of it, and noticed it has a lot of in and out movement, didnt really notice any up and down or side to side, but I will check that again. Any ideas of what could be wrong? The flywheel is tight, and when you pulll it out, the threaded shaft its on moves with it. Thanks.

Not really familiar with the 250r motor specifically, but this sort of play has to be due to either slack in the bearings or
a loose bolt or gear loose on the clutch side and /or the bearings loosening in the case, or crankshaft loosening inside the bearings.

Sometimes when a bearing locks up (dry and overheated, full of grit or cast piston pieces) and the crankshaft continues to turn, you can a spin a bearing, which messes up the press fit between bearing and (crank or case). Sometimes when the bottom end is replaced the damage i is just cleaned up, ruining the sensitive press fit, which can and will cause things to loosen up in the future.

You said up/down and front /back was tight so depending on how bad it is , It could just be normal slack in the bearings as well. I am not sure how much play is acceptable in this case.

Certainly someone more familiar with Honda 250 engines, or someone who does small engine work everyday could tell you more.

I do know that it is possible for the crank to be installed slightly off center between the cases, causing almost constant sideways pressure to be placed against the bearings.

Thanks for the response, some good ideas. I will check the clutch side to see if somethings loose in there, I really hope thats it, as Ive never split the case before.
I put it together enough to ride it a little, and found the noise I was worried about only happens when the clutch is disengaged in neutral, pull in the clutch and it goes away. What could be rattling in there I wonder?

Oh, and its a suzuki LT250r, not a honda, if that helps any.

Lol I noticed that a little too late, unfortunately during the golden era of the H250r, LT250, LT500, etc. I was too young to buy my own and my mother thought anything with a motor was dangerous. My first ride was a lt230. Not till adult hood did I get to own a 2 stroke a little 2002 blaster.
My boys first ride a '95 CR80R slightly detuned, he's 8 and weighs 65lbs.


I really can't say, the little air cooled blaster has 5 no-worry noises for every pending disaster noise.

if you don't already have a service manual, I would try to get one or find a PDF version. It's an invaluable resource when it comes to how tight, how loose, etc. Each and every part/ adjustment is detailed, with wear, play, torque specs.

A little in and out play on the flywheel is normal on these quads and the noise you are hearing is probably the clutch basket, also normal. I wouldn't worry too much about it unless is gets worse.
