69 BSA Rocket3... the Unholy Virgin

Got the lathe going then..

If it worked on the car engine it should work on the bike engine , the machine dont know or care where the parts came from !!

Thats what Im thinkin....

Well its always been ready...just dont have tooling for it, & dont know how to use it.I got a cutter off someone & went in blind.

Cool. I'm working on putting a Fairbanks Morse from a Wisconsin generator on my Triumph. It started but only ran on 1 cyl because it has 1 set of points and 1 lobe on the rotor. A dual lobed rotor should fix it but I haven't had time to work on it lately.

The distributor is electronic.Firing order is just a matter of swappin wires around.Being it doesnt run off any kind of sensor, my thought is that when the spark gets to where its suposed to jump, it will jump regardless of what direction its spinning.It will be awhile yet till I find out if this will work or not.If it doesnt work...Ill be putting a Boyer unit in....But I think this looks pretty wild hopfully it will work.

Shouldn't be an issue, just like a boyer works CW and CCW so should the distributor. The Geo and BSA both have 120 deg cranks so that should work. Awesome idea!

Hope you get it worked out dude....a mag is the way to go.

Man I've been thinking about your distributor set up and I'm not sure how different BSA's are from triumphs but a triumph cam turns half speed of the crank. So you need fire every 120 deg of crank turn, this means if BSA and triumph are the same your distributor needs to fire every 60 deg of turn. This is why my mag only fired #1 cyl on the compression stroke. Triumph has a 360 deg crank so I bought a 360 deg firing mag and I actually needed a 180 deg firing mag (360 crank turn = 180 turn on the mag). If the Geo distributor is designed to spin half of the crank then you're good to go. I've been looking for info on it but no luck so far. Not sure if you already know all this, I'm just trying to save you from some of the same issues I went through. I'm also looking for a 3 cyl tractor mag! If I find one that will work I'll send you the model number. Old tractor mags can be had on ebay for around $40

[Jeff L]

No....I didnt know any of that man.....I really appreciate this kind of feedback.My plan (like most of what I seem to do) was to just put it together at relatively cheap cost & see if it worked.I did run my plan across the guy who fixes our cars, & he says I will need the ICU off the car for it to work.Unless I can pick one up REAL cheap, I might be scrapping this plan.I have looked for a 3 cylinder mag... I haven't been able to come up with any.

On a whole other note....(fuckin ADD is great isnt it?)....no wonder I never finish anything.I picked up this glass lens for my tail light some time ago

...so I made this little spacer...with one of my favorite caveman tools...the trusty hole saw & I used the boring bar on my shitty little mill.

....the only thing is it doesnt have any clear glass for the lisence plate....but fuck it

[yona]

A super brite white LED could fix that .... small and bright ...!!

[Jeff L]

Right now the bulb is a regulal old 1157.Are you saying replace that with LEDs or add them for the plate?Brighter would be better.

[Jeff L]

I was able to scrounge up most of the little parts for my front drum.Now the front end is basically complete, minus one return spring & a cable.

[TattooLeeRoy]

Looking good. I would love to chop a rocket3, but I have been called sick.

[Jeff L]

thanks man....One of these days it may actually get finished

[Jeff L]

I decided that since the springer sale went south,& still have the neck bolt from it,I'd put the leafer back on.Just gonna slightly tweek it from how it sits now.I don't like the bars, so I'll make new ones.Still need to make a longer axle too.
