You could look at the VMC ignition too. About £130 All based on idm same as the others I believe

love the avatar

are you going to try a plan "b" on the three phase stators ignition circuit? It would be good to see all your effort result in something that works and most of the work done to the crank can't now be reverse engineered, maybe an External magnetic reluctance sensor to trigger the ignition instead of the internal Ducati pickup which you mentioned when you first thought up the idea

Yeah mines the large taper type. I didnt know if i`d get afew complaints about the chubby t-shirt but as most people on here seem to be grown up`s thought most would see the funny side. It does make me chuckle every time i see it still.

i thought maybe shielding the pick-up might be worth a try , maybe even something as simple as wrapping in tinfoil leaving only the side facing the trigger might cut out the ignition scatter your getting .is there any chance its a duff pick up ,as i expected any scatter to be at higher revs not down low .

brand new pickup, as you say it is worth trying the simple things like a wrap of foil, this is the fun of trying new stuff, you just never know how you can get caught out. at the moment i might as well try a few things as i cant afford the expencive option till after the party season.

well i tried to get a 3 phase system and came unstuck. so following links from shaggy and Gareth, i now have one of these on it`s way. over £100 cheaper than the kits being offered by the big german shops. VMC ignition . it works out at about £170 inc p+p though i have seen them sell for less than £100 on bidding it`s just a shame that it can`t be used with the Khepper CDI

Very interested in the quality and performance. Seems like a great alternative for Vespatronic or even standard electroic ignition when upgrading from points.

what make is the cdi in the kit steve , if its ducatti or equivalent that should mean the krptronic variable/mappable cdi would be usable with it . H

the kit arived today and it`s the polini version.
no instructions or diagrams of any type at all. so currently looking at lots of old posts on vespatronic type kits. the plan is to go 12v DC. so a bit of head scratching at the moment.

Aah ,isnt it nice when they trust us to be so clever we dont need the "destructions" ,they will only of been in technical italian that google translate would mangle anyway.better off without em. H

This little project has been dogged by things that do not fit this is mainly due to the use of the falc 1/2 case. it is not designed as a simple to use road case but rather as the basis of a race case. one of the reasons that i tried to get the Honda stator working was i had a hunch that the vespatronic type stators would not be a simple fit. i was right, the big lump that serves as the transfer needed a little ground from the outside to allow the flywheel to spin freely. also the backplate for the stator needed a little metal removed to allow the stator to sit in the case. all easily sorted things. a few pics of todays fun so flywheel and stator fitted the next job is to look at the wiring. for now i just need to get the ignition and lights working and at some time in the future rewire the stator for true 12vDC via a bridge rectifier. [i once contacted SIP to ask what flywheel and stator fitted a Falc case and they sent me a link to a standard ets flywheel and stator kit, obviously their staff have more incommon with warehouse operatives rather than engineers, tuners or enthusiasts but that seems to be the way in the world of scooters in general. (Rant over)] more fun after the new year and hope for a new mot in january

that is a tight fit , an only 2 bolts holding the laminates/coils to base plate ,neat shoulders/spigot on base to locate them tho . when using a bridge rectifier are you also thinking a zener diode regulator, as the recent links to banggood i saw a chinese copy of a honda rect/reg box all in one.if memorys serving less than £10 , H

£10 thats cheap. i could use any bike rectifier/regulator. single phase or three phase they all work well on single phase systems, i still have my three phase LC350 one knocking around and a TZR250 unit.
the kit i bought comes with what looks like an ac regulator so if i get it running i can see what comes out of the reg and consider a simple half wave rectifier as a temporary solution.
i`d like to know what bike these new kits are actualy coming from as the parts are likely to be very cheap

tzsteve , I don't know if this is of use, but here's a link to a thread on the LCGB forum where a guy has converted Varitonic to fully DC link (varitronic is Lambretta talk for vespatronic). All the best, George.

thanks mate, seen it, that guy is on this forum under a different name and is my tame welder. he`s done a couple with no problems so i will be picking his brains when i get round to doing mine. but it does look quite straight forward

MOT out of the way, as my mot testing buddy is a round trip of abut 25-30 miles i had a chance to have a little tootle. the timing seems a little advanced at mid revs so i`ll knock the timing back a couple of degrees and see how it feels. the motor seems to have plenty of go coming into the power once i got over 55 in 4th, not had a real blast on it yet so i cant judge the response at full revs. but it does feel lively for anyone considering one of the newer type flywheels from avotechnica.com via ebay at £180 there good enough and will fit a standard case with no problems. but they dont come with a flywheel holder of any type so you`ll need to buy or make one. the wiring was simple enough four wires red/black to CDI. blue earth. plus two live wires for lights etc yellow high power. blue/white low power. this will be rewired for true DC at some time. and the diskbrake will have to come out of the toy box for a little playing with, but thats another job for the future so current spec: Quatrinni M1-GTR, 34mm Amal, Franz pipe, own gear box, DRT flame primaries and clutch, VMC ignition, and the fuel consumption seems to be very good. a dyno run will happen (early feb i hope)
