Finally Made it - 1980 Magnum II

Kingsley Ned /

Howdy, been lurking on here for awhile and looking for a ped for even longer. Thanks to Rob K I’m finally the owner of a sweet ass Magnum. It runs pretty well and gets my 200 lbs up to 30 mph no problemo. Looking for some suggestions on what to do next, I already ordered some replacement shift pucks and trans oil. Figured I’d flip the clutch while I’m at it too. I like the stock look and don’t plan on kitting it out. Odometer reads 400 miles and it works !

Stoked to be here - Seth

Nice .

Now get the weed killer out and take care of that patio . ;)

Really . It'll make the bike look that much better . :)

Don't fuck up the side covers gasket. If you replace it you need to reshim the transmission.

Re: Finally Made it - 1980 Magnum II

You can make some very easy mods to a stock cylinder to get a little more speed and acceleration.

But, if you want to leave it stock, maybe don’t start that because it’s hard to stop.

well after a few weeks of riding goddamnit I want it to go faster. Thinking i’ll start with a pipe and upjet, trying to get around 35mph since that’s the average speed limit around me.

Replaced the old pucks and flipped the clutch. they were mush

No need to get a pipe your stock pipe will work great if it wasn’t modified to begin with

Pitch the stock air filter thing with the restrictive resonator to get a metal mesh filter, Dremel out your intake to 14 mm or post for one on Buy+sell, up jet carb to a size maybe 62-63#, W 212a atomizer or best bet get a 14 mm Carb and around 68-70 jet 212a atomizer

Drill around 1/4-5/16/ hole down into the exhaust and one into the cap I use a drill bit extender In picture

Sand or mill head flat

And you get this

Of course you have to remove the pin in the speedometer which is not an easy thing to do so it will read past 30

Before you do anything make sure your magneto is serviced and your timed correctly so read this completely

I like around 18° with this set up

I got two bikes with the set up one with a 12 mm carburetor and one with a 14 mm carburetor and they keep up with kitted bikes (not ones I kit though)

Both magnum and maxi heads sanded or milled give more power
