Must have been smokin crack when looked at being able to stuff the reed cages down in front, not much room for reed stops and screws to lower cages into front without modifications, must have threw the bare cage in there with no reed stops or screws:o. If I was to tighten the crankcase on these, looks like doing it in the crankcase with epoxy would be the way to go. Keeping this one mostly stock except for few minor adjustments, so no changes in cc volume on this one.
