My Yamaha YZ125 doesn't start but it has spark. What can be the problem?

SOURCE: i am after a diagram to help change clutch plates

Here's the deal. You get the diagram and I get a top rating on my answer. :)

Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site. In the event no price is shown on a particular part, the part is not in stock. www.babbittsonline.com/pages/parts/viewbybrandand/parts.aspx

Note that the first plate to go on is a fiber friction plate and the last plate is also a friction plate. A metal pressure plate goes inbetween each friction plate.

Please rate this solution. Thanks!

SOURCE: what is a used 2003 yz125 worht?

I just paid $900 for a good condition 2002 YZ125 with a new topend and after-market muffler. It does have a cracked gas tank (age/sun related), but I picked up the only used replacement gas tank I could find on Ebay for $49 and patched the existing tank to tide me over in the meantime so I could still ride it. So, depending on the condition of your 2003 model, I'd say it's worth somewhere around $1200 if it's in decent shape and $1500 if it's in great shape. If it doesn't run, don't buy it unless you definitely know what's wrong and how much it will cost to fix.

SOURCE: hi i was riding my yamaha yz125 2001 and it cut

make sure the float did not stick open and flood the cylinder. turn off fuel supply and remove exhaust pipe from cylinder. Does expansion chamber have fuel in it? It shouldnt- drain it. Place a towel over rear of front fender and on floor under exhaust port and kick motor over. Does fuel spray out? If so motor is severely flooded. Keep kicking untiul all fuel is purged from motor. Motor will likely start and run for a second once the fuel is reduced to a level the motor can handle. Reinstal exhaust and fix carb/ float problem. Hope that solves the problem.
