I had Andy at Grand River Racing do mine. I believe their site is grandriverracing.com, but not sure. You should really listen to what everyone else is trying to tell you though. There is alot more that goes into running alky other than just dumping it in the tank and going.
Your compression has to be in a certain range, you will have to spend hours jetting it, after every ride you have to purge the alky out if it is going to set more than over night. Your gonna have to buy a pingle dual fuel valve which is around $100. You can forget about trail riding unless you only like riding for a couple of minutes. Granted I have bigger carbs than you but if I get 40 minutes on a tank thats good. You are also limited to a couple of different oils. Make sure you run the right stuff, synthetics will not mix with alky. I was told to run atleast +7 degree timing, according to your sig that means you would have to buy a plate as well.which is $35. The actuall labor to get it done costs me $100. Plan on investing on more than one set of jets, and everyone on here know that jets add up quick at somewhere around $3-$5 a pop. If you plan on riding in cold weather have fun kicking it a few times, I only had problems when it got down to like 50-60 at night.
My suggestion to you is to ask yourself exactly what you want to do with your shee, If you add up the costs above you could almost get a play port from Jeff @ FAST. Which would be a much better choice adn probably run better than a bone stock shee on alky.
Its your decision, just thought I would chime in a little. And as for me going to alky I don't regret it at all, but I think our riding styles are a little different.
