    The profile and lift will be different by grinding the base circle so much and what about the surface hardening?

      Do not worry.
      Nothing changes.
      It is just 0.05mm on 6.5mm stroke of valve.

    Paul, Nice video I have an 02 en-450 and can tell you to be thankful the de compressor is gone. They had a nasty habit of breaking apart and causing lots of damage. Sweet looking bike though not many left running sadly.

    Wouldn't vapor blasting have been the safer option? Then you could have just polished afterwards. Im sure the cam still functioned fine after this but id be concerned about the material removed even if miniscule and also hardness etc... for durability.

    You are a good machinist and I enjoy watching the videos but I don’t like the idea of sandblasting and re-grinding cam lobes since they are case hardened.

      @@PaulXchannel no count it works well. Reliability would be a concern but I’m sure you didn’t even get through the case hardening on the cam. It’s just for me I’d rather have a new part and not worry, could you even get a new part for this bike?

    Me llama la atención que rectifiquen una leva en forma profesional de esta manera , con el tope de la maquina supongamos que queda redonda la parte de abajo pero las rampas de subida y bajada del balancín ??, son a ojo ? , mas o menos ?? el llenado de la leva ?? , como hacen para hacer dos levas iguales sin la plantilla de una rectificadora de levas verdadera ??,

    Hammering onto the shaft (into cold head) with power flow from inner race via balls into outer race? Is this good idea?

      Do not worry . Outer ring overlap approx. 0.01-0.015mm.

      Don't you think that a fine polishing could restore the roughness, without removing material like the grinding operation ?

      not true. I have 300+ mth on my 503 SM and yes, now it needs a rebuild, but I can say I also abused the bike on a circuit. Yes they are sensitive on oil level but once you check it regularly it lasts long.
