Modern Vespa

some observations ...

I had it installed for about 2 months and have temporarily uninstalled for the last several days (will stick it back in soonish).

with installed (not high speed / freeway):

1. lower mileage. 30-32 km/l -> 27-28 km/l This is to be expected

2. more clutch slippage / shudder at lower revs (10-15 km/h in carparks etc)

3. more 'go' when taking off at the lights (with ASR disabled). WIN!


I'm pondering the clutch slippage still. Was able to easily adjust my style. May install a malossi or polini clutch ...

Notes:
* It's a supertech so I can check things like mileage by using the phone app that records the telemetry
* using an Arrow after market exhaust

Lower mileage might be because of the way you take off with the Lambda Emulator installed.

Dr.Pulley HIT clutch is good for locking the clutch and preventing slipping, but this can cause jerks when you open the throttle at low speed. It is expensive. But I don't know anything about tuning the HPE transmission, having only worked on earlier models.

doubt this as this should be a minor effect when doing enough kms
