£1000 for a frame (why? A new one costs less?! The basic frame and s/a only is about £900 (plus the other parts like footpegs, adjusters, bodywork etc) £500 for a motor (good price), so you are now £1500 in.
plus some wheels (£110 for a rear rim, £100 for a front, £100 per wheel for sainless spokes and a build, tyres, tubes, brake shoes, bearings, oh yes and you need hubs etc etc etc) You can kiss £1000 good bye all day long.
Shocks £500 (more if you want or less if required)
Bodywork?
Bars, controls, throttle, new carb.
hang on a minute this getting expensive!
Oh yes and you have to build the thing. We even if you are very quick and very good and your hourly rate is £0.10 an hour, I cant see how on this earth you can build a bike of this quality for that price.
You you can then you are by far the better person that I am and I salute you!
Anyway, none of that matters, it's a lovely bike and would look good in anyones garage.
