I don't know anyone personally who has one but the feedback from around the various forums shows that no-one (to my knowledge) is entirely happy with it.There seems to be a problem with setting the timing correctly for all revs,particulary the higher range.
Although that is all second hand but I'd save my money until it's been proved otherwise.

Ive heared about the high revs bit.
I think they're ok on a 7000 rpm Lambwetta, but not on a 10,000 rev proper bike.

Taking the Lammy slant,I think most are happy with them on a mildly tuned bike but,from what I can gather,if it's a monster the vast majority prefer a "fixed" system.
I'm pretty sure the "Narwitch" lot in particular are very vocal on this view.

if you look on the other group (clue: a bit dull), you'll see that terry ward (lambretta dragster bloke) is importing vespatronic kits and selling for £180 to group members.  |

We use them exclusively for racing. I think its one of the best if not the best ignition i've used so far. Its cheap and reliable.
I use the dc charge circuit to charge the battery that runs all the gauges,power jet and shift light. It starts on the button. The reason people have grief setting them up is 1.Its a wasted spark system 2. on certain dynos they can interfere with the computer system. The operators dont appear to understand a way round this. So far its not broke even revving the thing to 11,500 its not affected it. If anything fails we'll look at it but at the moment its just a bolt on part. Neat indeed.
Also used on all Pt race machines.

ive got one one my pkxl, 1st thing is the difference in sounds, ie revin, before it sounded like a vespa, now sounds like a big trials bike.............  the rev range is quite amazing really. weather the double spark helps much or is just wasted i dont know. the main use is pulling away she now flys from standing position, ie traffic lights ;D can even get her to wheelie.........just put a sat natv on scoot( kept gettin lost on way to rallies ) will power the sat using vespatronic  was thinkin of putting one on my ss90 rep, but i think id prefer the old sound of the 44 year old engine on that scoot, ...............so on the whole if you want a better pull away and a revier scooter then there brilliant, prices are comming down as well.............. |

i use one on my race bike. it has a very strong spark and i had no problems reving even past 12k.
any advance/retard ignition will blow away any static ignition- if setup to make the most of the advance.
the trick is that you need the ignition advanced enough to give you more power down in the revs. you can setup a static ignition to have lots of advance low in the revs- but when the revs go up the engine will tend to detonate- this can cause seizes and holes in pistons. but a vespatronic will retard the ignition higher in the revs to avoid the engine blowing up.
vespatronic has a linear advance/ retard - if you plotted it on a graph, it would show as a straight line.
the very best ignitions have programed curves to give the best advance depending on the need of the engine at that rev range. some times some high powered ignition even advance again after peak power so to extract a little more power as the engines efficiency goes down (wider powerband). nobody makes a programmed igntion for a smallframe yet as far as i know. here in nz, a few people (with drag racing lammys) are setting up program controllers added to existing ignitions to program advance. i think this is the best option, but an expensive and technical one.

Hi I am trying to setup vtronik in my m1l kit, the problem is that at 5-600rpm i see some power los, like knocking, and after that the motor regains power up to 10.000rpm...do you imagine what the problem might be?
is it possible to have any cable connection problems...?
