One of the projects I've been working on finally got its testing day today, the aim was to have a very small/light low inertia flywheel but still have the ability to charge a battery as I wanted a race type solution that would still allow the use of a programmable ignition like the ignitech. After alot of researching, buying stuff, testing and then binning said stuff, I decided I'd have a go at modifying an existing system to make it work as I wanted as these systems are primarily targetted at the big bore engines I do to help reduce load on the cranks. I'd seen a similar system to what I wanted done by Ritchie at RSK on his RD500 hybrid and after having a chat with him I set about making my own (he had a company make his) So after a far bit of head scratching, lathe and milling machine work, I finally had a prototype, initial tests where promising but the charging system just wasn't man enough, so back to the drawing board. The next prototype is what I've tested today, it works exactly as I wanted and produces approx 75watts of charging capacity and upto 13.7v, the testing today has proved very positive with it just about keeping pace with the ignitech power usage on tickover, at 3000 rpm it maintains the battery voltage and at 4000 rpm it charges the battery more than is being used - result The flywheel weighs in at approx 360 grams (a stock one weighs in at approx 1560 grams), the unit is very compact and is fully compatible with the ignitech and dead easy to wire in Once I've done some more testing and got some miles on the test system if it all stays together and works, then I'll start making them to order and selling them as they will be great for race/track bikes that want a programmable ignition with a low inertia flywheel and for road bikes that are running mainly LED equipment etc, it may even be ok for a normal road bike with standard electrical gear, but I've yet to test that Below is a picture of the unit fitted, it starts off as a HPI system, which is then modified to suit my needs   |

Superb news Dave! You really are the man. Ive been wanting to see something like this for about 7 or 8 years now after i came across some of the race systems but found out they wouldnt be able to charge a battery and was a bit gutted to say the least. Keeping weight off the crank end and also having new stator and flywheel components is a win/win i reckon. Less chnace of old parts failing etc. I'm defo interested in one of these for my 421LC so keen to see how you go with testing as it runs a piggy back Zeel, but defo needs to charge a battery as the bike also has GPS Speedo, Thermo controlled Rad fan, leccy temp gauge as well as normal bulbs/LED mix. Anyway, suffice to say, yes I'm excited!  |

Hi Dave
This could be what everyone has been waiting for
No more deciphering which flywheel goes with which Stator or CDI and which wires need to be swapped
If we can buy one flywheel and Stator to run with a modern CDI it has to be a winner
I’m presuming it will work with standard LC’s and YPVS bikes
Good on you for this work, I think you are onto a winner here

Incredible. I love your ability to have an idea and make it work.

Brilliant as ever Dave There surely cant be another system as light as that ! You have literally reinvented the (fly) wheel !!  Well done mate, and I hope the testing goes well  Dusty |

Nice work Dave
Now how can we make it fit with a starter ring gear for my TR 🤣

just a quick update on this system, initial testing is still ongoing, only had one issue thus far and that was the test bike was sat in traffic idling on a very hot day and the owner put the fan on (forgetting that I said it won't charge on tickover), needless to say the bike broke down with a flat battery after about 10 mins of the running the fan !  Anyway, once back up and running (and not using the fan in traffic !), the bike has ran faultlessly and the battery has remained charged etc, it still needs more testing and I've now made 6 more units which I'll be fitting to a few bikes for further testing etc While its still early days, and I've yet to finalise costs etc, I reckon the system will cost between £300 to £350, so no more expensive than a power dynamo system, but having the big benefit of an extremely light/low inertia flywheel - it will need to be run with an ignitech or zeeltronic, but these are targetted at high performance engines/bikes rather than stock road bikes I'll do an update and write up at some point once I have more info and data |

Did this breakdown because flat battery won't power the ignitech ?
Only reason I ask is mine is on standard ignition system but still starts and runs with flat battery ( I know it's not a good idea) albeit not as well as with a charged battery.
Will this flywheel only work with ignitech? Or zeel as well?
Fantastic work tho.👍

Dave I'm going to need a new ignition system as I robbed the VAPE from my 400 build onto my bog stock LC (well you can't tell from the outside!) so very happy to install one of these rather than another VAPE.

Fantastic work tho.👍 yes stopped because the iggy needs a minimum of 10.5v (give or take) Yes it will work with iggy or zeel (using the correct zeel though as there are no source coils for the ignition) |

Dave, how did this testing pan out in the end?
Ive been looking at this type of modern ignition for a mate and was doing some research on HPI and came across this thread.

This is pretty cool! I would be interested in one for my 31k hybrid build, it is a dedicated back road burner and track day bike

Hello, is there any news on this beautiful project ?

funny somebody should bring this up, I've now got 6 systems installed on various bikes from YPVS's right upto big bore banshees, all are working very well so far, fingers crossed it continues
The system starts to charge around 2500/3000rpm, maximum voltage is around 13.5v, maximum amps is around 4 amps, so more than enough to keep a battery topped up. On the bikes that are just running an ignitech or zeel there have been no problems, I've got one fitted to a 385 YPVS track bike with the servo and will be interesting to see if it is capable of keeping the battery charged enough and stay on top of the draw from the servo
I've got one system fitted to a road bike, but is on a day time MOT so no lights to speak of, the next test will be to fit it onto a bike that is running all LED and low power usage components to see if it can keep on top of things
For now I am confident it will be more than man enough for a track bike running an ignitech or zeel to keep the battery charged and quietly confident it will keep the YPVS track bike going, but I'll have feed back on that in due course
Hope that helps

Thank you for the answer. I am looking at a new ignition for my 4L0 road car which has been sitting in my attic for 15 years in parts.
Merci pour la réponse. Je suis en train d'étudier un nouvel allumage pour ma 4L0 de route qui est en pièces détachées depuis 15 ans dans mon grenier.

Jon,
This is a bike I crashed on during the Moto Tour (Tour de France) in 2007. I have since moved and have a big place to live so I decided to rebuild it from scratch but with some fancy touches like a 700 TZ "ducktail seat".
I'm taking it apart completely to change all the parts but I don't think I'll be able to reach the level of your very nice restorations.
Jon,
C'est une moto avec laquelle j'ai eu un accident lors du Moto Tour (Tour de France) en 2007. Depuis j'ai déménagé et je dispose d'un grand local j'ai donc décidé de la reconstruire à neuf mais avec quelques touches de fantaisies comme une selle "queue de canard" des 700 TZ.
Je la démonte entièrement pour changer toutes les pièces mais je pense que je n'arriverai pas au niveau de vos très belles restaurations.
