Well, I made a typo in the factory manual specs: Front 8.40" at 33" behind front wheel center; Rear 8.10" at 20" ahead of rear wheel center. [not 29"] I've looked it up in the AMA specs and it differs from the service manual: Front 7.0 at 33.1" behind front wheel center; Rear 6,2" at 20" ahead of rear wheel center. That is a large discrepancy.
