Four years ago, I started to take apart my '76 150 Super to get it stripped and painted. The project didn't progress!! However, I have now decided to put in back on the road in it's original factory condition. The paint is Piaggio code 580 (described as beige but it's more like a mustard yellow). It has a number of battle scars and bits of surface rust, but the bodywork is remarkably dent free. There's absolutely no filler or post-factory weld. I'll be using whatever products I can find to keep the rust at bay, and I may even touch up the beige if I can find a good match for 38 year old paint.
The engine is pristine (later 3 port VBC1M). I've decided to put it on the shelf so that the scooter can be returned to factory at any time in the future. I am using a surplus PX150 engine, which will give me 12v ignition, EFL gearing/cruciform and 10" wheels. I decided to go 10" for the gearing and because I like the look (others disagree). With a PX rear shock and a 26mm spacer, I hope to achieve the 'squat' Rally 200 stance at the back.
I have a new DR177 kit which I bought five years ago and never used. I'm going to use it for this build because I want to experiment with tuning. Some people have altered the DR cylinder transfer ports to match the Polini, but I will be using a Pinasco 177 base gasket as a template. I am a Pinasco fan, so if this all goes wrong, I'll dig deep and buy the Pinasco kit, knowing that my cases are already matched. Conscious of the DR's inadequacies, I will be using Grand Sport rings (still 2mm but stronger) and a Polini 177 head. A 24/24e (original Dellorto) and SIP Road 2.0 Sport will be used. I decided against the full Grand Sport piston due to cost. Let's see if it was a good decision!! The aim of this engine build is to get good usable city power on a low budget, but I suffered a drunken internet buying accident and now have a Worb 5 flowed crank. This may prove a bad match for the other components. Anyone care to comment?
I will report my progress in this post, as others may be interested in how it turns out.
