DYNO RESULTS
Well, this is an excellent result, a straightforward exchange of kits and 17hp is delivered out of the box. No porting, no blending of transfers, no cut-cranks. Look down the bottom of the rev range and the Malossi ‘Sport’ (read ‘touring’) is pulling just as well, if not better, than the standard cast-iron barrel from the word go. More power right through the rev range, then just after 5000rpm as the standard cylinder is levelling off… the Malossi comes on-song and for the next 2000rpm it increases in power up to a peak of 17hp. The only problem we were having at this stage was fuel starvation.
By his own admission, the owner conceded the tank and carb needed a clean out and the scooter needed a service. We up-jetted on the dyno just to check, but the fuelling wasn’t a jetting issue… it was a flow issue. There is a common ‘carb-fettle’ which involves drilling the carb out and fitting spacers, but we decided to go a stage further for two reasons: 1) to check further performance gains, and 2) take no chances on fuel flow. We ordered a fast-flow fuel tap and a BGM 26mm fast-flow carb. That way we will cure the flow issues, and potentially gain more
power over the standard 24/24 carb. Once again, the carb is a bolt-off/bolt-on item, quick fitting, and cures fuel flow issues. The kit hadn’t arrived by press-day, but we will add the results in the next instalment of our Vespa tuning mega-feature.
Next month
Something wheelie interesting – SIP tubeless rims and tyres vs Pinasco tubeless rims with Dunlop ScootSmart tyres. A toss of a coin decided whose scooter gets which combo, we will be covering tech-specs and fitting, plus the result of our 26mm fast-flow carb and tap on the Malossi 210 kit.
