FOR RACE USE ONLY!
This is a service to remove, plug and weld the post mount on 6 speed inner primary's. Removing the post mount on the primary allows for greater swingarm angles when running chain drive so it does not interfere with the mount on the primary. We machine, in house, a sized plug to fit in the case once we remove the post mount. TIG welded and leak tested, this mounting point is now eliminated to accommodate larger shock lengths.
