recently rebuilt 04 ktm 125 bottom and top. The engine has less than 1 hr on rebuild. squish is set correctly and had a local guy check ring gap, check exaust porting, and tune carb to make sure it was correct. He gave me the go ahead. the cylinder was sleeved by la sleeve. Looks like a lot of scoring...

I know when reeds are delaminating they say to replace them. My issue is I have an early 2000's ktm and I bought new reeds but they don't sit flush against the cage at all. I would like to avoid spending $140 on Delta 3 reeds so I put the original worn reeds back in the cage and they sit...

Hey guys, I've finished up the engine rebuild on my 04 KTM 125sx. The last thing I needed to do was rebuild the master and slave cylinder for the front brake.

I'm rebuilding my first bike (ktm 125) and learning a lot. I noticed a lot of metal material in the cases when I split them and noticed some scoring and gouges on the walls that surround the crank. Curious what peoples opinions are on these and if it's anything to worry about. I'm new to this so looking for some...

I'm brand new here so hopefully im doing this right. My brother and I just bought a 2004 KTM 125sx and the guy we bought it from said the cylinder needs resleeved. He said he sent it off to millennium and they said it couldn't be replated. it looks like its in good shape besides the 2 areas on the...
