Hey fellow Pred riders!! I was wondering how hard it was to change rear sprockets and the procedure? I have a 40 tooth on there which i didn't change myself, and was wanting to put the stock 37 back on to see the difference. The 40 has awesome torque, but i was gonna put the stock back on and see if i notice a big difference in top speed. Does anyone know the difference in top speed from the 37 tooth sprocket to the 40 tooth sprocket? About how long would it take to change the sprockets out? Would i have to loosen the chain or anything? Any info would be appreciated guys. Thanx in advance. By the way, I'm gonna put an updated pic on here soon of my pred wit my new front and back bumpers. They are sweet as hell. They are made by mightybar. Here is a link of the front and back bumper on eBAY check um out. http://search.ebaymotors.com/search/search.dll?cgiurl=http%3A%2F%2Fcgi.ebay.com%2Febaymotors%2Fws%2F&MfcISAPICommand=GetResult&query=Predator&SortProperty=MetaEndSort&ebaytag1=ebayreg&category0=6000&st=2&s_partnerid=2%26category2%3D43962%26siteid%3D100&BasicSearch=&from=R2&catref=C3

first off there is going to be a difference in top speed of about 6 mph if your engine can still pull all the way to rev limiter. as far as how to do it, get the left tire off and the left hub too. since you have the 40 in the rear, the chain is probably adjusted all the way about as loose as it can bee to fit it, so loosen the two bolts on the back of the swingarm and this will allow you to spin the axle inside the swingarm which changes the chain tension. get the chain as loose as posible doing this. take off the 4 bolts and nuts that hold the sprocket on and remove it. installation is the opposite of removal with the exception of adjusting the chain. this procedure is listed in the owners manual. hope this helps - james

you probably need to loose a few links to get the proper adjustment
