OK, here's the follow-up on my March 12, 2010 (mail in date) California Motorized Bicycle Instructions/Application on REG 230 form.  I received the plate and Registration today, April 10, 2010; just under one month.  Copy of Registration in thumbnail below.  I sent in $18.00.  Note on the registration that the fee is $19.00; however, they show on the right side that they received $18.00.  I must owe them a buck.  I would suggest that folks send in $19.00 henceforth.  The CA regualtions say they can increase the fee each year by $0.50 without going through a formal notice; so, I think everyone will be OK if they send in $19.00 for the remainder of calendar year 2010.
