Well, OK, here we go. I have bought the 600-750cc version, the one with the point near the sprocket and 14 bolts. I got a DYNA DS4-1 ignition, as he suggested, and asked him to make (extra cost) a custom plate for it. All seems to fit together nicely, and the various parts went into place easily (a dry run only; not yet building an engine with it). It seems you can use any-length crankshaft (can you say 851/916?), and a combination of alternators. I will also use his vented valve covers with this. As for balancing, it seems that most cranks are balanced with the rods and pistons, but not with the flywheel. The latter seem to be balanced individually. You are keeping everything but the flywheel, and many after-market versions now weigh very little (see the photo of the odd TT flywheel I posted a while back). So you could say the weight loss is not that great if you have reached that point already. My concern will be properly installing the ignition pickups, related parts, and correct wiring. And, trying to figure out how to time it with no peep hole!. My weakness at electronics shows up there. Now the corrections will follow! Attachment:

Mike, When you say : You keep everything except the flywheel, do you keep the center portion of the flywheel (the parts that is made of a different material, steel I think) ? Another question : since the Dyna DS4-1 pick-up plate is mounted at the end of the camshaft pulleys actuation shaft (which rotates half less quickly as the crankshaft), does it make any difference to the signal ? I suppose there is no more loss sparks (at the end of the exhaust stroke)and the spark plugs ignite only at the end of the compression stroke. Am I correct ? Gilles |

do you get a timing shaft extension with it? timing will be easy. just put a tdc mark on the alt rotor and the mounting plate. how much did it cost? |

Yes, a timing shaft extension comes with this kit. I think Sauro is asking 800 Euros on Ebay. This price takes into account the fact that Ebay retains a 12% on the combined sale price and shipping charge. If you contact him outside Ebay, he will ask a little less. And considering that the $US is almost at par with the Euro, such a purchase comes much cheaper for Americans than for us Canadians. Gilles |

Thanks Gilles and Brad. You both added useful information. Gilles. The ONLY thing removed is the flywheel bell. You need something for the sprague, for the starter gears, and to space the alternator outboard. Maybe the location eliminates the wasted spark when using flywheel pickups. Many aftermarket systems mount the pickups on the right side, on the other end of the cam timing shaft, at the double cogs. Thanks Brad. But even after reading the DYNA installation instructions I do not know if the igniter boxes are still needed. The MG V35-V50 and Nevada 750 have very similar systems, and use the DYNA DS5-1 pickups. I really wonder if there is any difference. Yes, it is a good time to buy from OZ! Pantah Good has one on his bike. Maybe he will tell me if the Kokusan boxes are still needed. My attitude is that I will figure it all out when I get serious about using it. Thanks, MikeV Attachment: Attachment:

Sorry, I was sleeping, thanks for the wake up Mike. No Kokusan boxes are on my bike, but the Klotz needs to go in thru the breather. Bill |

Thanks for the note Bill. Then that would be one less thing to buy and add to the wiring. Neat. Do not know if the question about the usefulness of the PSH side cover was answered. But, it would save some weight, eliminate the Bosch pickups, simplify timing (I think), and be really cool to look at. MikeV |

Another question : If I use a Dynatek DS4-1 pick-up plate with this left cover, should I keep or delete the ignition modules ? I am not an expert, but I think the ignition modules provide the advance curve. If I delete the ignition modules and connect the Dyna pick-ups directly to the coils, then will the engine fire always at the same ignition advance at any RPM ? Maybe I should ask this question to Sauro. Gilles |
