Help. I have a '78 Kawi KE250 that i am rebuilding. I cannot seem to find a good replacement piston. Any guidance on where one might be available or an alternative that would work (with minor mods if needed) well would be much appreciated!

I checked all the places I get parts from and I can't find one. The part number is 13001-1017. |

I don't suppose an F11 piston will fit. I see that they are available. |

One thing that hasn't been given, is that after bore, pin diameter, is the compression height of the pin. this is the dimension between the edge of the top of the piston, down to the center of the pin bore. One year, in local class racing, in the 600cc stock class, there was one competitor that ran a different piston in their engine. this piston still had the 4 valve reliefs, top, and STD stamped in the top of the piston, but, it was 3mm larger bore. NOBODY caught on. I used to use a better Moto-Beta piston in my G31M, same bore, pin diameter, but, .020 more compression height, raised the piston deck the .020 in the bore. In my 215 all aluminum Buick V8's, a simple .036 bore allows me to use a .600 added length stroker crank out of a Leyland, early Chevy rods and HP 305 Chevy pistons. These pistons have .020 more compression height, raising the deck in the block to within .005 to the gasket deck. The lower performance 305 pistons would sit down in the bore .025 or so. Just an example of what is what, and don't be afraid to use pistons from other makes, if it has the dimensions you need, or, can work with, go forward. So, look for a piston that also has the same, or workable compression height. |

In the early days of Japanese motorcycles in America, our government decided to impose time limits to the Big 4, they weren't responsible for vending repair/replacement parts after 7 years from last year of new motorcycle year sales. So, H2 parts wouldn't need to be kept after 1981, and those parts supplies that had depleted, wouldn't need to be replenished for the 7 years. A friend of mine and I proposed to Kawasaki that we be allowed to set up a warehouse to house, and vend/sell out of production, over stock parts, those after the 7 year time limit, and that a portion of each part sale went back to Kawasaki, We almost got to do that. It was one extremely adverse American executive that thought every penny for those parts should only go to Kawasaki that stopped the whole works. Assassination was very seriously considered. |

I always assumed the policy of not stocking parts very long was intended to make motorcycles become obsolete when they got "old", therefore encouraging the sales of the new ones. If I'm right, that executive intentionally blocked your efforts, and if it hadn't been him, it would have been someone else in the organization. In the late '70s and early '80s I would occasionally to go a local dealer to buy a part, and the parts guy would condescendingly tell me that my '72 H2 was too old, and parts were no longer available. That attitude caused me to make the parts I needed whenever possible, and avoid dealers as much as possible. Nothing any car or motorcycle dealer has ever done since then has convinced me to change my attitude, although I've seen plenty of stuff that reinforces it. |

You will find that if you put ANY Kawasaki part into the standard search engine it will show up on at least 25 motorcycle, lawn mower, out board engine, 4 wheeler sites as if they have it but when you go there it of course says "obsolete". If Partzilla, CMS, or Ebay doesn't have it you have some serious searching to do. |
