Naaa nobody pissed me off, where do you get this idea... I cool as sh*te...

If I had loads of dosh to pay people to work for me, I wouldn't mind complexity...

But since I'm poor and design/built everything meself, it's got to be all fixable without sending stuff away.

So that's why, the less lecky or electrolecky stuff on me bikes the better.

OK, points will wear but I know for a fact they won't let me down on the side of the road!!!

I can remember drawing a dizzy top for a Fairbanks-Morse magneto to fire twin plug heads from a single coil, was it on this thread?

Somewhere there are pics of a shovel with Pat Kennedy rocker boxes and a single mag running a 4-cylinder dizzy cap running dual plugs. I'm still not sure how it works, but it looks awesome.

I know that bike. Seen it run and talked with the builder......scary fast, interestingly quiet running, until opened up..

I dream about this bike...

I get busy at some points in time, and have to take a break from sliding through the Journals grasp on my mind. I'm always happy to come back to find what cool stuff is going on all across the map-it makes all my little tinkerings and concoctions all the more worth it as well!! Great stuff, man!!

Why not just use a single fire mag?

If I remember right, it broke the records for it's class at bonneville. I remember it was running lean and farting....then cleared up and flew. Really flew. I want to say it was close to 200, maybe that was the HP.....
Dont quote me.

I do remember he said it made more power to the wheel than his Panhead with the same set up.

I was in love...

The late 75 to 80 XR had single fire conversion on their Fairbanks-Morse magnetos... Means only thicker Bakelite cover, one pole outlet on the coil HT plus little distributor on top of the rotor cams.

It's worth thinking about single fire, cause on a side valve with not so much full advance, you'd be surprised when the front cyl wasted spark appears on the rear cylinder, menacing at every rev to fire up not your engine but the manifold full of compressed explosive mixture...

Thanks....see how bad my memory is. Hence the reason nobody should listen to me.

Anybody know, would these MSF wires work on a distributor/coil setup to block the "waste" spark?

I have read that there's an significant difference between the salt and the tarmac in terms of required power to reach a certain speed.
Altitude, rolling resistence, grip, etc etc
147 is an impressive flathead number on tarmac it must be amazing on salt

Small engine repair shops are a good source for magnetos and parts. They were used extensively on stationary farm motors etc.

There's one interesting youtube clip where that bonneville racer is dynoed.

http://www.youtube.com/watch?v=_vw_LsEhzco


If you have time, check out this other youtube clip. It's about Fastest 45 flathead... Supercharged like the one here.

Visibility @ Beeville Sunday morning was about 100 feet due to the fog . I was watching the concertina wire at the prison and knew the approach to the venue but still missed it and ended up pulled off in the ditch with a bunch of other cats and we all had our windows rolled down and engines turned off, listening for traffic so we could pull a U turn and swing into the front gate . It was comical ,and the high humidity certainly has a major impact on carburetting .

Liked , and shared on potatobook .... That was awesome .I stand corrected , it's a 120 mph 45 .fuuuhh

It is important to note that had they been racing against each other , it is VERY likely that he would have still loaned him a helmet , a cylinder set , or whatever he could spare . If you dont have anybody to race against , than you aren't really racing , just "winning" , as Charlie Sheen might say .

(This does not apply to douche bags . You know who you are .)

That's the thing, surely worth thinking...
'
I'm surprised that waste spark system is in use in heavily tuned engines, anyway. I mean naturally aspirated engines. Doesn't it (waste spark of front cylinder) spoil the advantage what valve overlap causes or could cause to rear cylinder's intake; and it probably causes some extra heat too...

If anyone still thinks im just doing dual plugs think again. Im doing an single fire set up. Because of the fact stated above.

Anyhow. dragged my lazy ass an hour early to work today to get something done on this project. hopefully i have 2 small brass wirewheels to show for it.
started thinking about an ignition retard contraption last night. with my odd handlebar usuall ignition handle won't work.

tigwelder is up an running again.

Also started resto/modding the SU.

Start up this year is gonna be tight..
