need help starting out

My dad has an old dirtbike, that I would like to fix up and use. I would like to rebuild the engine, and do whatever is necesary to get her up and running. It is from the late 70s/ early 80s (not really sure). All I know is it is a Yamaha and says 400 on the side. It has the number 1W6-000507 in a couple spots. I was wondering if anyone could tell me what model bike this is, what size engine, etc. Also if they even make parts to do what I would like, where could I buy them? Thanks.

Re: need help starting out

Hey.. does it have two rear shocks?? or just one under the tank??
It's a two stroke, right??
Does it have a headlight??
What color is it?? Yellow or blue
Yellow= YZ400
Blue= it400
If it says 400 on it, AND no ones messin with it, its a 400cc

Did your dad forget what he has??
Is the bike complete??? if it is....
Remove the spark plug and clean it.. spray some WD-40 in the cyclinder... and check to see if you have spark...
If you have spark... remove the fuel line and spray carb cleaner in the carb... put fresh gas(mixed) in the tank and see if it will start....



Oh ya... be sure to check the tire pressure [img]/wwwthreads_images/icons/smile.gif[/img]

Yeah my dad couldn't remember the model number. A little searching on the net confirmed it is the it400 you mentioned. I'll try to start her as you metioned as soon as I get time. I mix gas and oil right? Whats the ratio? Is this going to be an ok bike or a total pos? I don't really care, I am stoked to ride it. Thanks.

Re: need help starting out

Go get some Golden Spectro oil and mix half the bottle to 2 1/2 gal....

It's going to be an OK bike AS long as it runs good AND you dont ride with newer bikes.....

Try NOT to spend too much $$ on it, just get it running and ride it [img]/wwwthreads_images/icons/smile.gif[/img] Remember a running rat bike is a happy bike.....

Why did your dad park it??

You can still get motor parts for it, but plastic will get expensive.
