Purple Dave's SC 500 Project
« on: February 03, 2013, 04:51:43 pm »
Well a lot has happened since I discovered this site in December.........I would first like to thank Freakshow for offering the makings of an engine......and SlideRulz and cyclegod for pointing out a near complete machine.....I would like to make very clear up front, I am a complete novice when it comes to machine restoration, so I will need all the help I can get to make this bike competitive.....I was always a RIDER not a MECHANIC.....that having been said, let's start work.  ???

The bike arrived yesterday ..........Yippee !!!




and for Slider29.......THE YELLOW HAS TO GO !! ;D

Purple Dave, welcome to the wonderful world of old bike restoration.  We've all been there, and many will share useful tips and tricks that will save you a lot of bother, while others will know a lot about the SC500 and/or where to get parts.  You should start by doing a search on SC500 on the site.  A good thread to start with is

http://ozvmx.com/community/index.php?topic=26902.0

A mate had one of these critters back in the day.  I was too young to know good from bad, just mightily impressed with the sound, the nice yellow/black colours, and the go fast bit of course.  it was way fast for a 15 yr old - scared the heck outta me.

Purple Dave are you going to keep it a 4 speed or go for the 5 speed box ? the great thing about the 73/74 Yamahas is the interchange between models . If I can be of any help give me a call . Iain

Is that the one off ebay?
I'd go for the grey silver paint job.

I'd be surprised if you couldn't find all of that stuff on ebay Dave  :-\COME IN CYCLEGOD (the Guru of all Ebay searches - can find things others can't) ;D ;D

There's a seller in OZ that sells Yamaha coils like that.  Woul dsave some postage.
Looking for YZ250C parts NOS if possible

Dave before you start on the ignition the SC can be made to work with its standard set BUT a DT400 cdi is a lot better solution and a shit load cheaper . the side covers are available from Prixhistoric F/glass .Air filters from UNI filter NSW .Topdog or speed&sport in the US http://216.168.60.165/speedandsportinc/index.tpl gear and Kick are DT 250,360 ,400 parts easy to get .carb to air box speed &sport again they make repo's , the rest your local Yamaha dealer as they are all general parts shared between lots of other Yamahas .  Give me a Pm and I'll send you a parts # list .
