New 70cc class dyno day

Update

500i's are still making money. The weak a/v can be cured with some pieces of 661 a/v. However with a 24" they are fine as is. They got springs and no carb but are every bit as reliable as the old lethargic 660
10 years on my "old lethargic 660"

Been leap froging it with a 462 through my strips, which is a lot lighter.
