StillStanding462 is the name I used at the 450 forum - won't go into why.

Okay so a few of you have mentioned the XS650 replacement coils from Mike's XS. I've just received mine in the mail today and I really would like to install them correctly... I'd hate to melt them because I hooked them up backwards.
I think a few of you have already installed these coils so any advice / instruction would be fantastic. I've got new wires and non resister plug caps (thanks to the group for that advice). My 1973 CL450 k5 runs pretty good on 1.5 cylinders... I can't wait to ride her when the right cylinder has consistent spark.

Sure wish someone would answer this, as I am getting some in the mail tomorrow.
I'd especially like some details on the physical mounting - the electrical part is easy enough.

Here's a link to how I just did it...

Thanks! That's pretty much how I'm fabricating my mounting brackets except I'm using a wider piece of steel so the coils will be further apart. I would have had is finished this weekend but multiple Halloween parties got in the way.

Be real careful about having the coils further apart - the tank won't fit on !!
I had to move mine in from the first position that I tried, because they hit the tank.
There's lots of vertical room, not much sideways.

COP - Coil-On-Plug coils are very cheap and plentiful.
From outboard motors to BOP Americans to aircraft.
Ebay to junkyards.........

The problem with COP coils is that they are too low in resistance for stock points or common aftermarket ignitions.
Without a way to limit current there is no way to use them.

Current-limiting resistors. Wheyou have 1.9 ohm coils and that is too strapped, drop in series 3.0-3.2 ohm resistor, about 5 watts, looks like a grey block of concrete. Dino suggested to keep aftermarket coils to 5 ohms.

Mounted and wired the coils. Bike fired right up. Plenty of consistent spark on both cylinders. Went for a quick ride then noticed a big oil leak out of the left rear cover. Looks like it's time for allen head bolts and fresh gaskets.
