A contact breaker ignition is prone to faults，only suitable for tuning to a limited extent and always a risk factor on long journeys.
This is why it is often replaced with an electronic ignition.
Riders of classic models such as the Vespa 125 VNB/GT/GTR/Super/TS and 150 VBA/VBB/VGLA/B/GL/Sprint/V/Super usually only had the choice between a BAJAJ ignition，which was discussed in terms of quality，or a first-class but expensive VESPATRONIC.
At the suggestion of STOFFI’s Garage，SIP has implemented a suitable solution.
The idea behind it is to merge two types of crankshaft：The basis is the classic Sprint crankshaft with original bearing and shaft seal seat.
This is combined by MAZZUCCHELLI ex works on the fan wheel side with a revised cone of the modern PX shaft，while the clutch side remains unchanged.
This makes it possible to ride the proven and affordable PX-E ignition on the oldies - while retaining the original Sprint bearings and shaft seals.
In addition，a racing shaft and a long-stroke shaft are now also available：The SIP racing shaft provides a noticeable kick with adapted timing，the SIP long-stroke shaft works with original timing，but with 60 mm stroke for a particularly high-torque result.
Due to housing tolerances，clearance or ignition problems can occur during ignition installation.
To prevent cables from being crushed or the base plate having to be reworked，we recommend installing a spacer under the ignition base plate.
Design：Racing/long stroke shaft
Stroke：57-60 mm
Shaft seal seat：20 mm
Bearing seat：25 mm
Thread/cone：M12，blunt/thick PX cone with M12 thread
Lima cheek：Φ 95 mm
Rotary slide cheek：Φ 97.9 mm
Application：Crankshaft for conversion to PX ignition
Scope of delivery：including connecting rod bearing
Conclusion：Perfect solution for conversion to electric ignition and at the same time a strong basis for crankshaft tuning.
Don’t forget new wedges，M12 pinion nut and star washer.
Order the PX Lusso ignition base plate and PX fan wheel (e.g.
SIP Touren，PX200 or HP4) at the same time.
The spacer for the ignition base plateis also useful .
“We’ve been waiting for this for years.
At last，the old sprint engines can be converted to electric ignition cheaply and reliably.
Perfect.”
