Finally got everything from SF. Now to get organized and get busy!








This isn’t all of them, there’s still the Motobecane VLX, Critical Miss, HobBAD Sparkle Butt, Ciao Ciao and the other DR350. But now everything’s more or less in one place and I’ve got my tools. I’m stoked!

L’s magnum and some laguna stuff!

a while ago i got L’s magnum up on my lift to pull apart the transmission and check out the shift pucks. the bike has 201 miles on it, but it has been sitting for many years and i didn’t want to just assume they were still in good shape.

well, they totally were.

everything in there was in great shape. totally not suprised, the whole bike is clean and in good shape. it was just one of those better-safe-than-sorry things.

besides, i still had the low mile PAZ pucks that were removed from sparkle butt when the prototype atomic pucks went in. since i had this thing opened up, i figured i’d throw them in.

i threw on a new clutch cover gasket and sealed everything back up and topped it off with atf.

since i’m putting this thing back on the road for L, and this is pretty much her first real 2 wheeled ride out side of bicycles and the hobbit she rode around for a bit, i am making it as little and compact as possible. i decided the rack had to go (though i’m keeping it so that it can be thrown back on for possible camping adventures or whatever) and the rear fended needed bobbed so that the tire was the thing that stuck out the furthest.

first pulled the carb to run it through our ultrasonic cleaner. it’s always a good idea to get that going while you’re doing other stuff to minimize sitting around time. while the carb’s cooking, i can take care of little stuff.

new fuel line, fuel filter. stuck a drill to the crank and turned it over enough to make sure the oil pump is pumping as it should. replaced the starting cable.

pulled the rear fender off and removed the tail light, then kinda eyeballed where i wanted the fender to end, rolled the fender back and chopped off the front of it to retain the stock lip on the rear (and keep that sweet ‘the marvelous moped’ sticker intact).
the carb was done by this point, so i rebuilt and reinstalled it.

i picked up a little led tail light for the rear. i think the stock lighting coil should run it ok? we’ll see. i haven’t mounted it up yet, because i’m still trying to decide if i want to drill holes in that perfect trunk or not. i did run the wires for it, though.


with the carb reinstalled, pump working as it should and a new sparkplug thrown in, i hooked up a fuel iv and fired it up with my drill. the thing started right up and proceeded to smoke out the whole 2nd floor of our building. it was awesome.

i’ve since installed a new petcock after unsuccessfully rebuilding the stock tap (i can’t find a proper rubber piece for it) and replaced the left hand grip. i also pulled the pipe apart and cleaned it out as best as i could, but it’s still pretty smokey.
i need to get some brake knarps, trim up the stock brake cables and then i can go ride the thing around and hopefully burn out the rest of the junk in the pipe.
then it’s a matter of wiring it up proper and getting the plate for it and L can finally start ripping it around sacramento!

in other news, the kickstart guts for the laguna’s gpr engine finally showed up from europe!
so i pulled the clutch cover on that engine and went to work installing the parts.
it required me to remove the clutch itself, which i wanted to do while i was in there anyway. the clutch pads look alright, maybe a tiny bit worn. i think they will be fine for now. also, it’s got yellow springs in the clutch, i have no idea if those are stock or not.

everything where it goes.

i don’t have a replacement clutch cover gasket just yet, so it’s not quite ready to go all back together, plus i need to fix some shady stuff the previous owner did to this engine. for example, see those marks on the clutch’s face plate? they are from the oil level bolt being replace with one that was too long, it was dragging on the clutch. how do you not notice that?

i also remembered that the previous owner had said the cylinder had some porting done to it. i figured now was as good a time as any to pop the top off and have a look. the porting is actually pretty ok. everything looks clean and nothing looks horrible. i’ll run it as is.

i bolted the engine back together loosely until i get new gaskets for everything, and put it aside. i hope to be able to afford to get the parts sometime soon, it would be awesome to have that bike on the road this summer at some point.

but then, i have so many project sitting up here..

some more mini magnum

so last time i had the magnum on my lift, i got the forks “kinda” on. i needed to work out a spacer for the headset nut and some spacers for the front wheel.
i was also planning on flipping the fork legs (left to right and right to left) to run the front wheel the right way around, but really, there’s no need for that with snowflake rims. it all depends on if i decide to use the speedo or not, as the speedo drive will run backwards with the wheel on backwards. i kinda do want to use the stock speedo, it’s got the actual miles of bike on it and it would be rad to run it, so we’ll see.
i also discovered one of the ball bearings had fallen out of the bottom cup upon assembly, so i pulled the fork apart again real quick to sick it back in there.

after searching high and low for a spacer, i decided to just cut the top off the headset nut and run it upside down.

i didn’t get a picture of my wheel spacers, but they aren’t anything exciting-just some washers that fit nice.

i decided to pull the side covers off to have a look at everything. plus i wanted to pull the wiring harness out. it’s not the cleanest thing, but everything’s in great shape!
i think i might replace the 12mm intake and carb with a 15mm intake and carb, but probably not right away.

the oil fill plug is still nice and rubbery! that’s rare to find on a za these days it seems.

if anyone needs a stock magnum wiring harness, including bar and brake light switches, i’ve got one for ya!



a dark poopy picture. i need a camera!

mini magnum!

since i’m waiting on figuring out parts for the sr250, last night i pulled down L’s magnum to start with the minification.

i picked up a set of maxi length magnum ebrs and a set of maxi length shocks and started tearing into it.

the shocks went on real easy, of course. the ones i grabbed are rad because they have 10mm and 8mm inserts for the mounting hardware, they came with the 10mm installed but i swapped them out for the 8.

i’ve never pulled a pair of these magnum hydro forks apart before, they are great! the best quality fork i’ve seen come on a moped. i was going to try and sell them off, but i may hold on to them.

the new forks went on super easy. i pickle forked the inner bearing race off the stock triple tree and installed it on the ebrs. it was a nice and tight fit, no need for a spacer!
i was also stoked to see the stock fork covers/headlight ears fit right onto the new fork! the up and down spacing isn’t perfect, but i can make it work with a little trying.

i also threw on the pair of $16 bikemaster bars i had originally planned to put on the sr. i like them on the magnum though, so they may stay! i’ll cut them down, of course.

now it’s just a little guy! those 300mm shox might be a bit too small. maybe i’ll grab some 320s and try them out.


as you can see, the rear fender is kinda weird to look at now that the wheel’s all up in it’s face. i have a couple ideas as to how to deal with that. i’d rather not trim the original fender, so i may end up removing it all together. we’ll see!

now i’m left with this rad bench-side cup holder. if anyone needs/wants a rubber magnum dash in great shape, let me know! same goes for the forks and fender, as i’m not quite 100% on keeping them just yet.


next is to simplify the wiring, vinegar the tank, clean the carb and oil injector, a little mini tune including a new chain and cables, and to get the darn thing running!

L’s puch magnum

a few months ago i got an email from someone looking to sell a couple mopeds that used to belong to his grandpa. i told him that i was interested in seeing some pictures.
it totally blew my mind when he sent a couple pictures of two nearly mint 78 puch magnum mkIIs. i figured the guy was going to want a ton of money, but when i asked what he was looking to get he said he was hoping for $400– for the pair of them!
needless to say, the very next day i enlisted the help of my buddy maitland and his truck and we went and picked them up.




i sold the one that was a little bit more rough with more miles (~1400 or so) and held on to the other one with only 200 miles on it. now i’m going to build it for L so that she will have a moped to ride. i’m hoping the sr will be great for her, but a little magnum will be nice to build confidence on. plus she’ll have a moped for rallies.



i almost hate to do anything to such a clean magnum, but whatever. i’m going to put maxi length ebrs and shocks on it, some shorter bars and possibly a disk brake on the front.
the engine will stay stock for now. it MIGHT get a pipe, but probably not right away. a stock za50 should get L’s 95lbs around town ok for now, i think.
