Now, that is a transformation!
But surely not a standard 150 lump?

The other bike is a 1931 Francis Barnett I have had for 20 years and I still haven't started to restore it.
The engine in the GP is a standard 1969 sx150, I guess its original engine got blown in the past before I got it into the family in around 1996, I did have to extensively repair the chaincase and attendant bits, weld up the fins on the head, fit a new barrel and piston (the old one had loads of bits knocked off) although I have thoughts of overboring it a bit and fitting an oversize piston at some time. All the other bits are what came with the engine. All the bodywork is original but again extensively repaired, I've got a pic of that lot I will post. then got my buddy to retrim the Guiliari seat that is on the bodywork pic
The frame was basically straight but the forks took a lot of straightening as did the back where number plate fits.
The restoration was written up in Jet Set a few issues ago as 'Restory'.

Your comment prompted me to have a look at the 'standard 150 lump'.Scootissimo wrote:Now, that is a transformation!

Last week I did a good session or two of porting and fitted big bore exhaust and surprised myself just how much improvement I could make to the engine with a little cash and a decent portion of effort, thanks for the kick.....!

The sort of time scale I'm well familiar with, but I'm just a mere novice, 10 years being my current best offering.sunrisemac wrote:....... I have had for 20 years and I still haven't started to restore it.
