Welcome to the site :cool:

Be sure and go to your User CP and update information relating to your location, type of riding, etc.

I am going to move this thread to the General Bike Repair forum so it will get more views. You will need to give people the brand, model, year, etc. for them to really be helpful in their answers.

Grab a spot on the couch, crank up a new post here and tell us a bit about yourself. How long you have been riding, what kind of riding you prefer, where you are located, etc. We will do our best to hook you up with some fellow dirt bike enthusiasts.

Again, welcome to the site, and shout if you have any questions!

wow - Amerisport - i have no idea how to set the timing on one of them - your best bet is to look on the flywheel for a mark that says TDC or TF or T or something - you can then lay the cam in and hook up the chain (the lobes should be almost perpendicular to the valves) - there are sometimes 2 lines of the cam gear that line up flush with the head when the flywheel is timed correctly to TDC.....once hooked up (and bolted down if the cam gets bolted) run it through with the kickstarter - make sure that you see the intake open, then a stroke later the exhaust (ie, intake, compression, fire, exhaust)

Mini j.

May I suggest you purchase a service manual for a Honda XR100. I don't have a clue what an Amerisport is but, if it is a single cylinder four stroke, it is most likely a XR100 clone made in China. A manual for a XR100 should show you what you need to know.
