I now have the frame all stripped down. It took awhile to get the tank rubbers out of the frame as I had to improvise with pullers.Swingarm bolt was rusted in but eventually got it out.I have got the barrel off the motor. Piston is soso bore sort of rusty and the head has been pocked by blown rings or bearings before the piston was put in. Forks are seized in their sliders but that is a problem to be tackled further down the track. Next is to split the motor and learn about the gearbox etc. Looking forward to it.
I am now ready to powdercoat the frame etc. I know there have been references to paint colours/codes in other topics but can somebody tell me what they think is the closest powder coat colour to use. If there is one readily available can you please tell me how I can get some shipped to Australia. ps just got a 400 MC5 to restore. Not sure which way to look in the shed at the moment. Oh the dilemma!
Finally after 3 years I am recommencing the resto.Now comes all the silly questions starting with.. I need a new big end pin and Al B says he doesn't have any. Is there another pin eg Wiseco that I can use even if the ends need to be ground down. The other question is I am after some stainless steel spokes for the ST. Can somebody tell me if they are available and from whom. Cheers Bill
The first new stages have taken place. I have got the tank repainted etc. Its more than ok but not perfect. That's what you get with people who are not experienced with old bikes I guess. The other stage is getting the new crank put in. This has been done where a new steel rod has replaced an old alloy one. Al B supplied me with the correct length pin as well as the oversize B pin. When the new rod was pressed together it was found that the new correct length pin was a loose fit in the lobes that would not survive if the motor was reassembled and operated. Has anybody came across this situation and if so what was their remedy. Do I just buy another crank and try again? The person doing the rod reassembly is experienced in this procedure with a wide variety of motors. His suggestion is to TIG spot weld the pin to the lobes. He has done this in racing jet ski engines and found it to work successfully. I know this is an almost last resort fix. Bear in mind I want the motor to last but the bike won't be ridden in anger. Thanks in advance for your inputs.
Okay, time to tackle the frame. My frame appears to have taken a serious hit to one side. The middle of the seat locating crosspiece does not line up with the centreline of the backbone which I am assuming is the result of a side on hit that has bent the wishbone. The reason I am stating the obvious is the wishbone appears to have been manufactured about 10 mm out in the vertical plane and so was there some inherent misalignment in the manufacture of the frames from time to time. I will try to straighten the frame out as best as I can but I am curious about the misalignments in both the vertical and horizontal planes.
