Rather than trust the skills of your buddy Bubba's second cousin Earl, who has a drill press and almost all of his fingers, your flywheel and ring gear will be cut using a CNC mill using time tested lightening patterns. Don't take chances with lesser products when the result will be spinning at 6000 RPM right between your legs...
Lightening the flywheel on the early Tonti Guzzis is the single most noticable modification that you can make if you're building a classic sporting machine. Lightening will make your Lemans or V7 Sport much more responsive to throttle inputs, much easier to shift, and much more fun in the twisties!
Complete CNC flywheel and ring gear lightening jobs start at $325, including balancing. Smallblock lightening is slightly less, as only the ring gear is modified. Featherweight lightening jobs for racing applications are also available. Turnaround time is typically 3-4 weeks.
While it is recommended that you paint on your own timing marks by degreeing the flywheel, timing marks can also be transferred from your old flywheel. Please ensure that your flywheel is in servicable condition before proceeding with lightening.
