I'm trying to get the piston out. removed the retaining rings and got them out, but i'm having difficulty getting that pin out of there. Manual says it's supposed to slide out easily, but it can move side to side for about 1/4" both ways. Any ideas or did I miss something? |

It only removes and installs that easily when its new. After the engine has run, you need a piston pin puller to get it out and if reusing old parts, to put it back in. Some take a hammer to it (I dont recommend that). You can buy a piston pin puller (The HD tool is listed under the "tools" section, pg# A-9 PT# HD-42320) or you can make your own using threaded rod, long nuts and various spacers (undersized piston pins work really well!) DONT drop the piston pin retaining clips in the case! |

ah, thanks for the reply erik. I noticed that as I looked at the piston even more, and yes, I"ll need that tool (or a hammer). Do dealers sell this tool? Rob |

I doubt the dealer will stock it. They probably get theirs from Snap-On, Mac, Ken-tools, etc. I'd do an online search for a generic "fits-all" type toll. It shouldnt be hard to find. I made mine with the threaded rod and spacers, but I did already have all the parts 'laying around'. Some other style pullers will also work, but you might end up with the same deal as the threaded rod and trying to find spacers that work. |

If you are using a new piston, it wont matter.The pin will slide right in. |

yeah, I remembered I'm getting a new piston, so I did the hammer idea. I didn't hit it very hard at all, but it came out. Thanks for the references and ideas~! |

I think I'll be needing that piston support plate...unless there's alternatives? |

I've never used one, sure would make it easier, but not necessary or you could make your own. You have two choices: you can mount the piston on the rod and slide the cylinder over the piston or slide the piston into the cylinder (while on the work bench) then slide the whole assembly onto the rod and insert the pin. The second option is easier imho, but DONT drop the piston pin clips into the crankcase! Install one clip in the piston before you get to the rod with it. For future readers: The reason not to use a hammer is possible damage to the rod and rod bearings. Wash the cylinder thoroughly with soap and water, then you may use carb and choke cleaner, brakeleen, etc. Make sure everything is well oiled before you start moving the piston in the bore. |

PS You have installed the updated high performance oil drive gear? 2000 model year Blasts were most prone to this gear failure. |

hmmm, no i have not. if it's an easy to get part at the dealer's then I'll certainly do it. It's hard to get time for my bike as it's sitting in grandpa's garage and he's getting ansy. I double checked the rod and everything after the hammer for damage and found none. Everything should be okay. |

High Performance Oil Pump Drive Gear pt# 26391-06 Should be readily available at the dealer or from American Sport Bike and perhaps any of our other sponsors. You can wait to do it since you dont have the cam cover off. You'll have to pull the rocker cover off again to do the gear, although it may be possible to finagle the gears out without pulling the rocker cover. Just dont wait too long. |
