four stroke tech still does that mod. it costs 90$ wich is well worth the money, but you have to send your clutch parts to him, and ive heard bad things about turn around time. i really wish he would sell the parts along with instructions so you could have your local mech. install it. ive heard many people say its the best mod theyve done. you keep your auto clutch, but you can grab the lever and rev just like a sport quad. sounds so fun!
