SCOOTER DETAILS
Name of scooter: PX220LC Martini Racing Scooter model: PX200. Date purchased: About 10 years ago for £100. Inspiration for project: The paint was inspired by the one of the most iconic rally car ever, the Lancia Delta Integrale in Martini colours. Time to build: Ten years, most of it by myself apart from the ally welding and the paint. Frame modifications: Cut and reshaped panels, trimmed rear frame section with sunken rear light. Twin CR250 radiators fitted in toolbox, cooling holes for radiators, holes for cooling hoses. Frame and fuel tank cut away for increased carb and filter clearance, spare wheel brackets removed and electrics relocated. Cutdown front mudguard. Headset modified to suit Aprilia brake master cylinder, fluid reservoir and stage 6 display. All done by myself. Specialised parts: Water-cooled Malossi barrel and water-cooled standard head, all the ally fabrication was by myself with the welding done by Didge at Mecweld. Self-made reed block and inlet manifold, self made exhaust, one off flywheel cover, VW water pump with adjustable water pump control. Strengthened side stand to prevent floorboards bending. Engine: Malossi 210 original, Crank: Series Pro 60mm Bell Crank, Carb: Keihin 35mm AS, SIP fast flow fuel tap, BGM reed valve, Flywheel machined down to 1500g, Ignition: Kytronic 16 map, Exhaust: Self made expansion with SIP silencer, Clutch: BGM superstrong with SIP springs and XL circlip, Gearbox: P200 with 37T DRT 4th, Porting work by: myself. Dyno done by: Shiny Red Tuning in Stroud. It’s currently producing 22bhp and 15Ib-ft. Other unique details: The barrel base was skimmed by 0.5mm to give timings of 118/178 with a 60mm crank. The barrel top was also extended by 4mm to allow the head to sit into the bore to centralize it. The exhaust port was widened, lowered and a one off bolt-on exhaust flange fabricated. The bore was then ceramic plated at Aptec in Gloucester. CR is 10.5:1 with a squish of 1.3mm. The cylinder head needed to be put through vacuum impregnation to seal it, works well so far. Top speed: On current gearing it’s about 75mph. Paintwork: Banger at PRH, Stroud, prep and paint, Vital Signs in Stonehouse, graphics. Powder coating: Pete Marks in Stroud. Overall cost: These things are never cheap. Hardest bit: Probably keeping going with something that’s taken so long to complete. Any advice or tech tips: When it’s freezing cold in the garage and all going wrong just remember it’s a hobby and you’re supposed to enjoy it! Anything still to add: Pinasco casings, SIP speedo, new gear ratios, maybe another exhaust. Anything you would have done differently: The shocks, tyres, exhaust, carb, clutch, crank, ignition, seat, grips, battery, were all different when it was first built. Favourite dealers: SCK, SIP, SRT. Thanks: Banger at PRH. Gary at Shiny Red Tuning. Gus for the barrel and many others who have helped over the years.
