What I always tell people who want to do this is go down to your local Department of Motor Vehicles and ask them.
Be sure to get their name and any documentation they can provide you.
If your Department of Motor Vehicles does not do the inspection then go to whatever agency does the inspection and ask them.
That is the safe way.
Then again if the bike is already street legal you could just go for it and see what happens
I'll bet that if you set the bike up correctly it would handle great.
