Hi, I am new, I have taken the Smartech Winner 3, however it has 1 speeds.
I have bought the kit for the second inclusive speed the pinion, I have gotten off him and I don't know I have climbed on him well or I have put us everything, I would not like to make damages to the gear. On my manual of the car reference is made to the gear to a speed the code of the produced smartech it is: [link=http://www.smartechracing.com/web_2006/product/cars/10341/main.php]10341[/link], looking on the site of the smartech there is already a model to two speeds code [link=http://www.smartechracing.com/web_2006/product/cars/10343/main.php]10343[/link] for case you have the manual? It would go only also well me an exploded of the gear or a squirt made to correct hand understand I have reassembled him well. Does to end, have to also perform some regulation on the gear?
Help I beg you to me. 
I am Italian
