be far easier to use an alternator mounted ignition and system

Have a search for silent hectik or electronic Sachs

Silent hectik is my personal fav

The biggest problem would be locating the hole in the case for the distributor bore. There's no reference surface on the case, so you would need to locate the hole by reference to the centerline of the cam. That's doable, but would require some pretty sophisticated measuring tools. I'd turn the job down if it came to my shop. Wouldn't want to see the customer's face when he saw the bill.

You would need to us an abbacus to work it out since you don't like computers.

yes carbs!

maybe if you took a block that was already machined you could use that to make fixtures for machining . Just a thought, Ive never done it

Just install a 1978 engine.😁

thats funny...i have a motor and a frame...few odds and ends lol. im just building or trying to build a bike.

guzzisteve · « **Reply #11 on:** February 25, 2017, 03:03:46 PM »

I think it's all set, you only have to enlarge the hole in the block. I haven't done one either but a few here have. My cover plate is leaking so I'll be looking in there and swap the oring soon coming up.

troyhamilton · « **Reply #12 on:** February 25, 2017, 03:14:43 PM »

i ve been pretty busy so i havent had the time to pull the cover off. i think it could be done. i want to run points lol. if i can get my honda gone so i can accumulate some more parts. in time ill get it done! ive built some crazy stuff.

johnr · « **Reply #13 on:** February 25, 2017, 03:21:46 PM »

Curious to know how you plan to drive it?

troyhamilton · « **Reply #14 on:** February 25, 2017, 03:29:10 PM »

im looking for a dead bike. to be honest. i need a trans. swing arm, rear drive...Im not sure even what fits my bassa frame. we need a what fits what thread, lol

BillinPA · « **Reply #15 on:** February 25, 2017, 03:46:05 PM »

Have not done one myself, but I think in addition to the hole for the dizzy, the dizzy itself you will need a different cam. The FI cams do not have the gear to drive the distributor

troyhamilton · « **Reply #16 on:** February 25, 2017, 03:50:24 PM »

Billinpa you are correct.

The part number for the '97-'00 EV cam (2905 3350) is the same as the Cal III, so there's a chance it might still have the gear on the cam.

If the hole isn't machined at all or incompletely, it really wouldn't be a huge deal to do it. A friend did his with a hole saw! The perfect fixture-in-the-making is an old distributor lower housing from an (original) Eldorado.

Bolt that to the block, with a couple of bushings in the bore, it would guide the shaft of a (self-made?) cutting tool perfectly straight.

troyhamilton · « **Reply #18 on:** February 25, 2017, 04:22:49 PM »

I think it would work. im going to dolly my motor into my bathroom-workshop tonight. dont laught i rebuilt a distributer and a few other things lol. its huge!

guzzista · « **Reply #19 on:** February 25, 2017, 04:36:53 PM »

On my 94 Cali, the engine has the hole in the case and the oval cover. Have seen a 95 Cali Carbie with the same hole and cover as mine. My cam, when removed to install a B10, did not have the gear for the dizzy. I suspect that at least from 94 0n, the dizzy gear went away.

troyhamilton · « **Reply #20 on:** February 25, 2017, 04:40:15 PM »

just went to the shop/tool room...fully machined! woo hoo! no gear on cam though...but its good.

Are you sure about that? I'm not sure on the 95, but on a 98 and 2000 it looks machined, but it isn't completely finished. You may need to open it up for the dizzy shaft and gear, all the way to the cam, and then go deeper on the larger diameter where the dizzy body seats, if using a dual point distributor, that is.

Oh, yours is a 98. Don't know why I thought 95 ?

troyhamilton · « **Reply #22 on:** February 25, 2017, 06:42:31 PM »

well it sure looks it. i dont have a dizzy to fit it and it was pretty cold out there. ill take a gander tommoro.

troyhamilton · « **Reply #23 on:** February 25, 2017, 06:56:52 PM »

any one know what mm the hole should be? i can find that out but i can see the cam turn when i spin the motor.

of a machined and non machined hole please anyone?

you know me, but no lol. I think 5 years ago my wife took a picture of me grinding something at night and the sparks were beautifull and its lost to history lol. but no, im the do no harm dr. frankeinstein now...

dxhall · « **Reply #26 on:** February 25, 2017, 08:09:15 PM »

I was thinking that there was only the casting ridge where the hole would be (as on my '96 Sport 1100) and not an actual hole in the case where the distributor shaft goes. If you've got a finished hole there, not a difficult job. Having raced with point ignition systems though, I don't see the purpose.

troyhamilton · « **Reply #27 on:** February 25, 2017, 08:33:20 PM »

ill try to get a picture of it in the morning. i gotta wrestle a bunch of stuff outa the way. heres my theroy on points. they usually dont fizzle out all at once like electronics do. i can file the points in bum f egypt, make it run enuff to get home. but as for racing and points i have a 73 f 250 that im running a 429 and i make 450 horse, lol

I don't even know what a dizzy is (except for those of us stumbling toward the tents at certain Guzzi Rallies

), but what I've read on this thread suggests you might want to simply find a P8 computer and "go with the flow".

still just stirring the pot brother! ive been helping a neighbor on his farm. hes been outa town...
