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..

prototype atomic ZA50 pucks

atomic mopeds and sf moped mechanic andy has got these new 2 speed pucks he’s wanting to prototype, so i’m letting him throw a set in sparkle butt to see how it goes. they are harder than the standard atomic pucks and supposed to be more durable for big boy kitted ZAs.

these are a set of unfinished prototypes, the completed ones have been flattened on the edges…

…as seen here.

i didn’t really get any pictures of the process, as i was working on a scooter on the other lift for first kick. here’s sparkle butt all buttoned up after, though.


he plans to rip around on it some next week, and then hopefully i’ll be getting it to sacramento where it’ll be my little sac ripper. it’s doug’s rally bike, but i want to keep it fresh and make sure it’s not a pain in the ass for him like the laguna always was.

also, new shop toy awaiting a cart that should hopefully show up any day now
super stoked!

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.

SPARKLE BUTT puch maxi

there’s a kinda long story behind this maxi, and it kinda goes all over the place. i had a foxi (ktm style that accepts puch engines) that i was going to build for L. but the gas tank was so rotten that it was a total loss.
i had a little k-star e50 already built for it, and had most of the parts needed to build a complete bike laying around, just no frame.
latebirds of la were throwing a rally and my bff doug wanted to fly out to sf and take me and his west coast bike (a poopy derbi laguna) down to la to play. however, i had no working mopet and no money to get one of mine back on the road.
doug, being the total sweetie that he is, decided to take this newport frame he has hanging in his garage (in upstate new york, btw) and get it powdercoated all crazy rainbow darkness and ship it over to me, free of charge.



with doug’s frame i was able to throw together sparkle butt maxi, using the front end and rear shocks from black betty, the rear wheel for my moby 50cc race bike that hasn’t happened yet, bars from dirty, a borrowed hi-pipe from atomic andy, seat donated by the lovely dr.thomas and a slew of other random bits i had laying about.



we went to la and the rally kicked ass. sparkle butt, however, sucked ass. that pipe, you see, it meant for a high-strung 80cc dirt bike, not a not-even-ported kstar with a 19mm carb. i had no low end at all. once the thing finally got moving, though, the pipe would come on and it would book for being a not-even-ported kstar with a 19mm carb!

(_stole this picture from the late bird’s facebook page. dunno who took it_)

down hill it ripped!

a little while later it was creatures’ turn for a rally. andy took back his pipe and i traded the e50 bottom end for a za50. with the help of paz, i rebuilt the bottom end with a race crank, new bearings and paz shift pucks. flipped the first gear clutch and ported the cases for a gila.
i had a proma circuit pipe laying around that was meant for L’s foxi forever ago, and a 21mm carb left over from some other project. atomic andy made me an intake manifold and i was good to go.




this time the bike performed flawlessly. i threw some buddy pegs on and L and i ripped around sf on a post rally date with fellow dorados troy.

sparkle butt is now doug’s west coast ripper (till further notice) while i get silly on his poopy laguna. more on that in a later post.
