One of the tuners at Chopper city used to do this all the time. I visited at both shops from time to time to get more informed. There's a lot more involved in a proper tuned resonance than meets the eye.

Definitely. But well tuned pipes make all the difference.

It is really crazy how much power a ported & properly piped two-stroke can make. I made the mistake of trying to ride a 125cc motocross bike that was piped to hit between 17 & 18K rpm. I suppose the guy was full of it, but I was told it made 53hp on the dyno.

Cut the key way on the steel rolls & removed the excess from the ends. Assembled the bearing blocks.

Machined out a worn duo cone on 777 front wheel hub. Put in an insert fabricated in house.
It’s part of the oil seal for the wheel bearings.

Has anyone dealt with this? There are different gradations, this one is 400, there was an instruction in German somewhere, if I find it I will add it. This is for sharpening

That's a harsh looking toothbrush

I have never seen a stone on a handle like that before. I could see some instances where it could be useful for reaching in/around for deburring/polishing, but that's a new one to me.
