So last Thursday I tore the thing down. On Friday I took the tins and the frame to the people who will be painting those. I did the frame myself on the 650 but I'm way too busy right now to take that on. Especially with the short timeframe I'm giving myself on this one. I want it done sometime in June. We will see how that works out. So the plan for the intervening weeks until I get the frame and tins back is to take apart the engine and clean it up. Quite a lot of oil on the front side of it, I think the guy had a bad exhaust leak. Other than that it looks good. Going to have the bolts and stuff plated and the ignition boxes rebuilt. Then I'm going to refurbish the handlebar switches and build a new wiring harness. Not sure this will be done by the end of June haha.  |

Man, looks like you've got a great bike to begin your build project with tdub56!  |

Very nice, if it were mine, I`d ride it as is, as a surviver.
Not too many survivers out there any more, most are being tore down for parts, pretty soon there will be tons of parts and few bikes to use them.

I couldn't ride it as-is. The front of the engine is covered in oil, the wheel bearings are shot, it has a later swingarm and wrong rear wheel. The bodywork/tank had started to rust, the seat pan was from a S model and disintegrating fast, and numerous rubber parts were cracked/not there. Plus more. It would have been a survivor if the PO had stored it properly. But he didn't, so lets move on. I'm not interested in driving around on a 40 year old bike that hasn't been maintained very well. Thats not safe.
I'd like to think that my bike will be something that will survive another 40 plus years. I'm a young guy so I need something thats going to last another 30 years at least. If there will be lots of parts thats great!

Finally got a chance to work, been busy at the house. Got the cylinders off using the tapped hole method. The outside two were stubborn, the middle was easy. Now I can finally start getting everything ready to go back together. Questions: 1. Is the scarring on the piston normal? Rebore recommended? 2. Here in NL, 91 octane fuel is the max we get. Should I have the heads reworked? Some pics:     |

That piston does not look like normal wear. personally, I would re-bore. You then know exactly what you have and don't have to worry again for years.

crank rebuild req'd i can almost guaranteed. you'll see why once you split the cases
91 octane (0% ethanol ideally - shell ) ok on stock engine

Make sure the rings are free and groves are clean, clean some of the scuffs off the piston skirts with emery, lightly hone the cylinders , check piston ring and cylinder clearances to the book, if ok...tune it properly make sure the oil tank screen is not plugged and pump is running fine , run it...wow you dorks have a ton more cash then i do. If that engine is near the top of spec tolerances...20,000 more miles when tuned right...hassle free. I have run piston slapping bell tinging H's that sounded like diesels coming down the road at 90psi per cylinder and could still stomp a 4 stroke crap bike into the dirt. no white smoke screen streaming from one pipe going down the road..crank seals are awesome. Lou  if you think i'm wrong..check some of the shit crap bikes RB has fired up and gotten 1000's of more miles out of. do major rebuilds only when required or when they are going to the strip and track. my 2 cents |

you're right,500's are still fairly easy to get cylinders...H2's...I get every last mile i can squeeze out of a set of bores.  |

Thanks for the input guys. I think I'll rebore. I don't think I'll have to do it much in the life of the bike, and you can do it a few times. It wont be ridden every day or anything, since I have multiple bikes and the weather is pretty crappy down here.
Now I'm looking for recommendations of people in Canada to bore/chamfer the cylinders and to rebuild the crank. With the exchange rate right now I don't want to send this stuff to the states if I can avoid it.
