Hi, Blogwit.

I looked at the bth but at 500uk they are out of my price range, i was thinking on the lines of contactless coil and a box with a maped advance.
Thanks for help.

Wolram,
I fitted the Mistral engineering Mag replacement kit to my Venom and the difference was UNBELIEVABLE, the best single mod I've ever done to it, I also have a BMW R69S with the B-T.H self contained electronic Mag-generator and that ones a beaut too.
The mistral one uses the Rita system which is now out of production but there are alternatives, very similar, using Boyer Bransden, try RGM or Norvil, they still advertise them, much cheaper than the B-T.H.
Only thing is as far as I know for Rita or Boyer you must be on 12v, and you'll need an ignition switch, the B-T.H is self-contained, and in my opinion, better made.
Either are dead easy to fit and set up.
Highly Recommended.
Cheers

There's also this: http://tinyurl.com/329wh3 I've just installed one on a Gold Star. Haven't run it yet but it looks like a well made item. Others I know who are using rave about good running and easy starting. This replaces both the dynamo and magneto as a unit.

Hi Wolram,
This is the Mistral unit on my Venom, the coil I mounted under the tank in the tunnel, the amp unit is under the seat.
Cheers

I love it when threads take a haitus for a year and then suddenly come back...
If I had unlimited funds, I'd outfit my Venom with a new BT-H unit, and stop messing around with my K1FC. Why do they have to be so darned expensive? I know, I know... they need to recover tooling and R&D costs, etc. Also doesn't hurt that they're the only ones making a self contained, flange mounted magneto replacement that doesn't force you into a 12V conversion, and doesn't look out of place. They even have a magdyno replacement now for those Gold Star guys!

I thought about making my own ignition system,
a housing and shaft would not be a massive
engineering problem, a trigger, sensor, pick up,
could be chosen from available components, the draw back is the elctronics, i draw the line at
circuit design, one that would allow for minor
voltage drops would be good, and one with mapable advance would be ideal.

Actually, a few years back I toyed around with the idea myself along with a couple of colleagues from work (one an instrument engineer, the other an electrical engineer). A microchip and digital advance programming is relatively cheap and easy. The biggest costs are designing and fabricating housings, and the final assembly labor. There's really nothing special about the electrical components.

You'd never get rich off it, and you'd never survive if it was the only line of business, but we determined you could make decent profit if it was one of many products offered. Still couldn't see how you could charge $800 to $1000 for a mag replacement though... or who apart from serious racers would buy them at that price.

Hi
Happy to oblige, Velo, but no, unfortunately, I only have the one Velocette, and I bought it when I was a teenager and they were cheap(er).

In answer to your question re. the brake, its an ex-works Yamaha TD3 unit that belonged to Mick Grant at one time and (reputedly) was in a bike that won an MGP at one time. I used to have another out of a production TZ250 in a Norton, it was almost the same but didn't have the airscoops and the linings were one piece, this one has 3 piece linings made of different material depending on how hard you grab.
Keep looking for a Venom, they're great bikes.
Cheers
Oilyrag.
