has anyone ever done a complete restoration on a 250sx? if so, how hard was it to remove all the wiring, motor, and all the brackets and other assorted parts? and, has anyone ever rebuilt the top end on their 250sx? how hard was it to remove the camshaft, timing chain, and remove the piston? i am getting ready to resto-mod my '85 250sx. i am gonna port the head and put a 300 big bore kit in. any help would definitely be appreciated. thanx in advance.

 

where did you find a 300 kit to fit the 250sx

 

Another question is WHY????? It is a near 400 pound 3 wheeler (wet weight) and shaft drive. Are you going to use it for pulling, or do you want to race with it? All the stuff you mentioned is pretty easy to do; all of the books lay it out step by step and the pictures are pretty good. You may want to check your local library if you don't want to buy one.. Our library had 4 books on 3 wheelers.

 

J&M ATV supply has the 300 kits. They sell to dealers only so you need to call them and see where the nearest dealer is. I work for O'Reilly Auto Parts and we are dealers for them. J&M's # is 1-800-367-9603.

 

thanks for the phone number for 300 kit iv go a few 3 wheelers myself 5 250sx 1 250es 1 250r 1 200s and a 185 with org tires still on it

 

i found the 300 big bore from powroll.com. they still have a few left on their shelves. and i want to do this just to be different. i don't like having what the next guy has. plus, with a little more power, it will do even better wheelies through fifth gear.
