Anyone using a vape sport ignition?. What have you set your timing at?

This is my general advice for fitting advance/retard systems is this.

Fit it, and strope it at high revs and check it is retarding to about 17degrees. If not, adjust the timing. You might find that at tickover it is at about 25degrees, but that isn’t as important as ensuring that the it won’t blow up at high revs.

It is a starting point.

Set it at 24degree to regarding to16 degree
Cheers for the help

A mate is thinking of fitting a vape sport to his TS1. Its fitted with a TSR touring pipe and sits at 60 at 6000 revs.
When he rides its usually in a group, doesnt go faster than 60-65.
What would his timing retard to at this speed/revs ?
Hes worried that it might not have retarded enough and he might be better off with the road version set at 17 degrees static.
your thoughts...

What would his timing retard to at this speed

You'd need to find the technical information on the ignition system, specifically the ignition curve ideally on a graph indicating the timing at given revs
Use that along with the Lambretta Gearbox analyser (free .xls to download via a google search) to know what revs for given speed to know the timing at a given speed

you would need to know what gearbox, sprocket ratio's you are running though..

the problem is are the ignition charts available? I know with the scootopia system that the charts do not exist. I emailed scootopia about them and they said they did not know!

When you buy the SIP Vape ignition it comes with an instruction booklet which illustrates the timing curve showing very clear and specific values at varying revs.
Unfortunately I can't find any link online, only to the Vespa version.

I think the Vespa chart is exactly the same for a Lambretta as it’s the same system but with a different stator backplate.

Having fitted one to my P200E and to mates Jet 200 I suspect you are right but can't confirm whether the CDI and ignition maps are the same.
