How can I tell the number of gears I have in my bike?

Owner's manual for bikes will not tell you how to use the gears. Just Google "how to shift gears on a bike" Find one that shows the same type of shifters you have (does not have to be the same brand of bike). Better yet, find a local bike co-op or bike shop to show you on a bike stand before you hit the road (hopefully not literally).

crimped plug wire or improper spark plugs installed , I don't recommend running resistor plugs on these

tell me more about two-way gears. I have never heard term in over 40 years of bike repair

Need manufacturer, model, number of gears and color to properly tell you what your bike is

serial number on engine and frame ! shape and design of plastics and bike as most years have some sort of change ! take pictures and numbers to KTM dealer !

Not Necessarily... If you are not a professional athlete then the number of gears you have does not really matter. What matters is the range of the gears. You need low enough gears for going up hills and high enough gears for inclines.

The shift cable is likely too loose, but there are multiple items to tighten, lubricate and adjust on just the derailleurs, let alone the rest of the bike, before it's safe and ready to ride. I would suggest you get some assistance from a more knowledgeable friend, a bike co-op or a bike shop.

Wish I could come up with a line of B.S. as good as their service department does. You have a slightly bent shift fork. Tell the jerks to fix it. It is a problem, it is not right, and it is covered under warranty. Tell them you really don't want to get creamed when the bike pops out of gear and doesn't want to go back into gear as a cement truck is coming at you. If you let them stall you until the warranty runs out it will cost you around $1400.00 to get it fixed. Contact the Regional manager for Yamaha ASAP. Google "Yamaha Motor Corporation" http://www.yamaha-motor.com/
What I am afraid will happen is that the dealer will do the repair and install a new shift fork then tell you they could not find anything wrong so you now owe them the cash because Yamaha will not stand the repair cost for a non-existent problem. Send Yamaha a certified letter as to your concerns and insist someone other than the dealer inspect the bike to confirm the problem. Keep a copy of the letter and the postal receipt. Is there another dealer in the area?

The diagram below shows how a shift fork moves a slider gear left and right to change gears. A slightly bent shift fork would not let the slider gear "dogs" fully engage into 1st gear.
