I just boaught an 2002 50 Suzuki with no plastics engine runs well but, How can I tell if it is an LTZ or an LTA? Does the 2 stroke run off mixed feul or pull form an oil tank?

 

Well since it's a 2 stroke you want to premix a 2 stroke oil with gas, I'm not sure the ratio you want, but it will be between 32:1 and 50:1 most likely. To mix this properly you will need a ratio rite cup, they are made to help you mix. If you don't have one, a little thing from the kitchen, a container that measure to "1 cup" will get you a 32:1 ratio in a 2 gallon fuel container.
Math: 2/32 = .0625 gal 2 stroke oil. .0625 gal 2 stroke oil = 1 cup 2 stroke oil.
About identifying the model, I'm not sure. Some of these guys who know how to decipher the VIN code, which should be somewhere on the machine, maybe on the frame.

 

The LTZ is a 4 stroke.
Your 50 has a oil tank for the 2 cycle oil. It's an auto injection system. You do not need to pre-mix unless it's been converted to do so.

 

you should be able to tell by sound, 2 stroker are more of a weed wacker sound. [img]i/expressions/face-icon-small-happy.gif[/img]

sorry had to

 

Thanks for the input. Is does sound like a four stroke, So im pretty sure it is the LTZ but there is an oil tank just under the seat, I plan on tearing into the bike this weekend, replace the spark plug, change the oil and put a new pipe on it.

 

They did not make a 4 stroke in 02
