I have a pro x2 600 what add ons did you do to get the sled to rip as you call it I am going to put in a set of v force reeds and gut the air box I have not pulled the clutches aprt but it looks like a yellow primary any info would be great
Add-ons? i really dont have any add-ons, ive listed what i have done. what i am recommending you do is a little research on tunning sleds
i read some of your other posts im not sure what your definition of fast is my sled does around 80mph because of the steep gearing. Change your helix in your secondary over to something else maybe a straight angle(once again dont know what your looking for). Gears, gears gears, find a gear chart. As far as gutting the airbox i only took out the foam in it, sealed the airbox with rtv and took that slp mesh (the stuff that lets air through but not water) over the opening. work on carbs to run probably leaner than recemended.
i will try to pm you some basic tuning info that i have on my computer but all the info you need is on this web site you just need to dig a little bit
