this is quite an update

i worked with my friend, michael, on a grande i had sold him a few weeks ago. he's got an engine with the intake bored out to 13 and the window inside the case carved out and the crank cut. he also has a 13:13 Dellorto, Malossi Air Filter, and the Simonini Circuit. This is what the biked looked like before we startedHe wanted to put some lower handlebars on so we took all the controls off and then the stock handlebars, mounted up the new low ones, marked where we needed to chop to shorten them width wise, and then got out the hacksaw.
yeah, it went pretty dang well. we also shortened all the cables for the new handlebar height, switched out his left controls as there was a busted brake lever part, tightened up his brakes, fixed his tail light blowing problem (hopefully), put on a headlight, wired for that and a horn and a little hidden killswitch that sits underneath the back left side of the seat, it's so sweet how it's secretive. but anyways, here it is, done about 4 or 5 hours later.
whew! dang, that looks good.
i also worked on my friend, meagan's engine as she just bought a grey ciao off ebay that didn't have spark. i tried to diagnose it very quickly and thought i had figured it all out, so i split the case halves, drilled out the intake, put it all back together as i wanted to do that for her as well. when i tried to test for spark to see if i had fixed it, still no worky. so i need to get under the flywheel again and check over all the wires again. here are the photos from the case spliting process as i haven't posted those before:

flywheel off, here are the coils
i removed the little collar piece that the points rub on, that's called the cam, right? well, also, take out the woodruff key, so it looks like this:remove the nuts that hold the case halves together, like this.don't forget to take off your cylinder! also, i had ladybugs crawlin around and living in the fins of this one!

next, you can either put it in the oven, or if you have a 3 jaw puller, like me, you can just pop it off right away. also it can save you from having to put in a new crank seal as you won't damage it with heat, they cost 8 bucks a pop which is quite a lot to me. make sure you check the old one before you just leave it in there though, you'd hate to go through all this work and not even look at it and have a leak. some would say just replace it no matter what, which you can do if you want as well i guess.
anyways, i always put the crank nut, or whatever that's called on the end before i use the puller on it, as it can widen the tip and cause you not to be able to put the nut back on later, so it just keeps everything where it's supposed to be. you'll notice a pop once you start cranking down on that puller and then the cases will split apart like so:
here they are completely apart, yep. one of the bearing stuck in there, on the side where i wanted to bore out the intake, sometimes they both stay oh the crank, which makes it really nice to work on the engine as if you don't need to replace the bearings, you don't need to remove them (as they would bend and not function properly after removing them whether or not they were good to begin with as the inner and outer race get bent) oh, here's the intake before:
and the inside:
anyways, and i don't wanna get shards of aluminum in there where that bearing is, so i took one of jason's candles (sssshhhhhhhhh) and melted a little wax to seal it off as i didn't have any silly puddy. it seemed to work alright, although it was kind of a brittle wax, and so if i did it again i'd need to use a softer wax. also, i only did this because my crank seal was bad, otherwise when i would have gone to melt all the wax out after the cutting, the torch would have melted the seal, which would be dumb.then i got out the trusty 'ole rotary tool and started on iti only took a little off the inside, out the outside looked something like this, as this is a photo from a different engine, actually, the one michael has now:then i put the crank in freezer, as well as took a vaccum and sucked up all the shards that were all over and inside the engine, took one of my roommate's creme brule torches from the kitchen as we don't have a proper one and melted out all the wax. then i sprayed a bunch of times with carb cleaner just to make sure that all of the pieces were gone, then put a new oil seal in, brought the crank back and pressed the case halves together. i used a hammer lightly by the way. it should go back together pretty freely though, as the different in temperatures of metal help with that.
lastly, jason and i went to handybikes yesterday without knowing that they were having a liquidation sale as they hoped to sell the entire warehouse soon. it was our first time there and it was a dream come true. jason will probably have a write up on his blog which you can check out and if there are any extra tidbits i wanna add about the trip i'll put up another little post about it. but here's what i scored, everything NOS!

CEV all chrome short headlight bucket
CEV puch style bulbs with sockets for non sealed beam bulbs
CEV headlight clips to keep your bulb in, we got 100 for less than 99 cents!
Two sets of Domino Grips, still in the plastic
Front Brake knarp kinda things that you stick the cable through, kinda like a on road bike but for italian mopeds
Buddy fold down pegs
Franco Morini Variator inside cylinder piece (to try out on a stock vespa variator as it's a little longer)
Franco Morini Rear Clutch...COMPLETELY disassembled, or rather, jason and i looked up all the individual parts off a diagram so that i could build one from all the NOS replacement parts they had lining the shelves...it's going to be pretty crazy to put this together, and was FAR more expensive than i realized until after we had left (jason and i are kinda kicking ourselves, but it'll be something new to try out as they are very bizarre clutches but are interchangeable with vespa variated ones.
and lastly,
A Piaggio Ciao/Bravo/SI booklet that i'd never seen before, it's pretty cool.
You know what's also pretty cool. BJ from handybikes, i can't even describe him to you. Just so sweet and just wanted to make our visit special and gave us a tour, and understood our passion for mopeds, and showed us all these little treasures in the warehouse. he's pretty great.

crazy race car, not really sure what to call it

also, turns out that the grab bag was for local pick up only but i missed that in the german shipping details. i'm trying to negotiate for some of the smaller parts to be shipped still, we'll see. otherwise, i haven't paid for that auction yet, so it'd be like i never won it. but the engine has been paid for, so that's a go!

Simonini!

*EDIT*
Photos of random parts! who knows what's all in there!I just won a german ebay auction...for this:24 Mikuni, 90cc Simo kit, Simo Cases, Simo CDI.
along with a grab bag of parts and hubs and other CDI and a wheel set and ciao forks and the list goes on and on, i'm not even completely sure what all in in that grab bag of parts. looks like some cylinders and head and carbs and HT coils. all in all, i spent 358 euros, plus shipping which has yet to be determined. I got it for a super good deal though. i'm so excited.

however, I'm debating whether or not to put my malossi engine up for sale once this comes in the mail. probably makes more financial sense. we'll see though more pics when everything comes! not sure how long it's going to take.

4/78

i love the way top tank mopeds look, who doesn't? i especially like the way magnums look, again, who doesn't? as we all know, i love piaggio mopeds, but they never made a top tank!

i know this isn't a new idea but i still have yet to see someone actually finish one of these bravo top tank projects. my MINT frame is courtesy of Joe Woytasik, the tank i got from a random dude on ebay. it's pretty clean inside, but has a small dent on either side where it looks like the magnum forks turned into at some point.
but it'll be fun to strip the paint and use bondo for the first time and then do some duplicolor engine enamel on it. i still need to fabricate a bar and eventually weld it in. i can't decide if i'm going to strip this frame as it's in such good shape. it's like it's brand new. but i'm not sure if i'm sold on the color for this project. part of me wants it to be white or black, or maybe some other color. in any case, the subframe, is immaculate. looks like it was never even used (i know that's not true) but there's no grim or belt shavings...ANYWHERE.

here's a crappy photoshop mock up with some snowflakes i don't have, not sure what wheels i'll end up using on this project.
i don't have a seat yet, this is just a picture of a magnum seat i stole online, also not sure what i think of the tail part of the frame. i might need it to attach the seat, so i'm leaving it for now till i find my seat. it also has this really cool tool box that's just so well designed, i don't think i can get rid of it!
this bike is going to be really pretty though. winter project for sure.

70cc polini
malossi reed valve cases
simonini calibrata
malossi/dellorto 19mm carb package
simonini CDI
malossi multivar
malossi belt
ebr crossbar
Bravo forks
vespa SI cross mags
2.25 x 16 SAVA Front
2.50 x 16 Hutchinson GP1 Tubeless Rear
Buzzetti White Sidestand

still learning how to tune a PHGB carb, thought i had it down and then soft seized last night. haven't taken the cylinder off but seemed to run just fine so i don't think it was too bad. if not, have a malossi 70cc on the shelf. i also need to tune the variator more, first i had too heavy lowering my RPMs when it varitated too soon, now i have too light not allowing it to variate all the way. we'll get there though. right now it's running high 40s, but that's with those lighter weights in. so we have room to grow here. there's a lot of buzz about mikuni carbs, who knows, maybe i'll try and finagle one in there someday, but for now, i'm very happy.

yes it is true

i moved to kentucky, and put my crazy project bike together and rode it around for a week and a half. and then promply took it apart again. it is fast, but it i will be faster yet once it's tuned. also, i have a few things on my to-do list for it:

fix rear brakes
check.

the hub i was using didn't work in the cross mags. i was stumped as i thought all vespa hubs were interchangeable, however i couldn't get any of the ones i had to grab enough in these cross mags. it took me a long time, but i figured out that there at at least two types of vespa mag hubs. the only difference i could see was that the metal brake plate that has the actual pad on it is shaped differently. the one that works in the cross mags has a sort of triangle point in the center whereas the other ones are completely round on the inside. pics to come of course.

the engine mount holes aren't long enough on my frame for the multivar and malossi belt, so i have bad belt tension right now, in fact, i was surprised i could even start it, let alone start it no problem every time.

front axle barely fits in forks. i seriously have just a few threads holding one side on. i'm supposed to get bearings in from crush bearings this week, maybe sealed bearing conversion before ghost ride? but probably not. i have a bravo spoked wheel set and the axle on that hub would fit perfectly, however it's stuck in that hub at the moment. i should probably focus on getting that unstuck rather than mess with sealed bearings this close to the rally. maybe some pb blaster or something.

i also need a new headlight bulb, i really wanna hook up my horn too, but i need to figure out where to mount it. the bike is very simple looking and so just slapping it on will make everything not so good.

again, pics to come soon, once it's back together.

PIAGGIO EXPLOSION!

last weekend i had a good time putting together jamie's green ciao, frame compliments of gabeb. i was missing some parts though, so i had to take parts off two other ciao frames i have (the red one in the photo and some other stuff i took off of my top tank project's frame a few months back).
here it is:
hardwired w/horn!
stock cylinder
bored out intake
cut crank
13:13
single speed with malossi black springs
eventually i want to put the lightened clutch shoes on but can't get them to fit in right now. i also want to put the 80mm pulley on, but if the acceleration is crappy, then i'm gonna just wait and variate it when i get down to kentucky. i have two variators waiting for me there.

oh, and i bought a giant bag of soil on saturday and carried it on the back! it was great!
here's the cut crank
bored intake
inside, not the smoothest job, but i was cutting it real close on that top edge there and was worried i was going to wreck the rotary intake seal, so i smoothed it out as best i could without getting too close to it.

wa-bam!
