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!

rally torn down + dirty’s dirty shock

not too exciting i suppose, but that rally from the last post is just about ready to go to paint. gotta stuff the cables and wires into the frame, remove a few more little things and it’s off.



also, the yamaha yz80 rear shock finally showed up. it was $10 shipped, though i’m wishing i had spent a bit more and got a nicer one.

the seller said it was in good shape and ready to bolt on and go, but i’m not so sure. i can’t compress it at all with just my weight. not sure if i should be able to or not, but i fell like i should be able to.

i guess i’ll just clean it up and see how it works? i won’t be too bummed about tossing $10 if it ends up being trash.

that’s pretty much the last piece of the suspension puzzle, now to get to cutting and welding!
erm, once the welder arrives, that is. haaa

dirty fork and a couple small things for the sr

i’ve not posted much lately because i’ve been mostly tweaking my ninja. i don’t know if anyone really cares about me and my 09 er6f, so i haven’t really bothered. if you DO want to hear about it, let me know!

anyway, i picked up this all-in-one handle bar switch thing for the sr. it’s got everything but a start button on it. if the bike were mine, i probably wouldn’t bother with half of the electrical stuff, but it’s gunna be L’s and so i say it needs it all.
i’m was a little bummed that it doesn’t have a start button on it as i didn’t plan on having any other buttons or switches on the bike, other than the ignition switch.
so why not a keyed ignition with a start position? it works like one you would find in a car, you turn the key to start and it’ll crank the bike over. you let go when it fires up and the key springs back to the on position. why don’t motorcycles use this style of ignition anyway? the only thing i can think of is they want you to be able to start the bike with both hands on the bars. there’s no other reason i can think of.
the fit and finish of both of these parts are kinda meh, but they are robust enough to hold up, i think. besides, i’m on a $1000 budget for the whole build.

oh, and my fork bits for the dirty moped showed up!
i’m totally taking this build in a different direction than i started with, and i’m super excited about it.
i also have a yz80 front wheel of the same vintage on the way. one good thing about using old little dirt bike parts is that this whole front end, including front wheel and caliper (assuming i can get one at a decent price), is shaping up to cost me a lot less than a set of hydraulic ebr moped forks, and these are much better quality.

i might be getting fancy with the rear end of the bike. i’m still sourcing parts and trying to make sure my ideas will work out on paper before i commit to spending paper. i’ll fill you in on all that later on though, once i’ve made some decisions.

so yeah. how’s life?

dirtbag virago

i’m mostly posting about this bike because i don’t have anything else i’m quite ready to post about just yet, plus it should be in here somewhere.
this is a bike that i built for the dirtbag challenge in 011, but didn’t quite finish in time. poll, the guy that puts on the dirtbag every year, told me to finish it and use it in 012, so that’s what i did! kinda.

here it is when i got my hands on it. 1984 yamaha virago xv700. hadn’t been ran in a year or more. abandoned at the shop, my boss sold it to me for $200, i think.

i stripped it down and put most of the bits on ebay. i think i made back $175 in selling parts. i lowered the front by flipping the top triple tree, this allowed me to drop the front a good 3″ or so without pushing the fork sanctions up through the triple, which would interfere with the bars. i used the stock handle bar risers and threw some moped clubman bars on it and was stoked.

i cut the rear subframe off and engineered a rigid rear end that would allow for the swing arm to drop so that the rear wheel could still be removed. because the bike is shaft drive, it took a little critical thinking.

got a honda tank off ebay, hammered the tunnel a bit so it would fit over the frame, found an angle i liked and welded in some moped fender brackets to hold the tank there. that left a bunch of room in the tank tunnel, so that’s where most of the electrical lives. the seat almost had padding!

modified a moped headlight bucket to bolt up to the forks, threw on a cheapo quick pull throttle, fashioned an intake out of some pvc and a k&n filter, made a seat pan out of some metal shelving, bolted on an autozone trailer tail light threw together a wiring harness, zip tied in a scooter battery and called it good.

here’s jamie lookin like a little bad ass on it-

a useless mirror to try and make it a little more “legal”

the bike and i made the 012 dirtbag challenge, but i got about 80 miles through the 100 mile ride my battery crapped out on me. here’s the bike where it left me stranded for about 3 hours in the woods with no reception while i waited on rescue.

i was eventually able to get a hold of justin, and just as he was picking me up, a truck rolled by with another dirtbag bike in the back and they took the bike back to the party for me.

it’s such a fun ride. 15 year old tires, no fork oil (most of it has leaked onto the front brake and tire), no foot pegs (feet go on the engine cases), no padding for your butt and having to push start the bike makes it an interesting ride, but surprisingly not all that uncomfortable! and it’s so much fun to rip around on. it’s pretty fast for an early 80’s 700cc cruiser!

i know these photos are horrible, as are most in this blog. i’m working on getting a good camera, when that happens i’ll pull the virago down and take some quality photos.

more sr250 parts!

well ok, just one new part. the vm32 came yesterday! it’s a super rad little carb. screw top and main jet access on the bottom of the float bowl’s going to make it a cinch to tune, too!



probably the best part is that it fits right on to the stock intake manifold, which is still nice and supple after all these years.



the only thing really holding me back from throwing this bike together with what i’ve got and riding it around is my wheel situation. i really want to go 18’s front and rear, but rims are so expensive. i think i might be better off scouring ebay for 36 hole dirt bike rear wheels that aren’t totally beat and re-purposing the rims, you can usually pick one up for around $50. that’s like half the price of a single aftermarket rim.
actually, i think i might do that. i’m trying to keep the total price of this bike under $1000. original purchase price, all parts, paint, reg, everything. i’m totally on track to making my goal, but i gotta be careful and buy cheap everywhere i can!

sr twofiddy parts

i’ve had most of this stuff sitting on my desk at work for quite a while now. i’m nearly done collecting parts!


progressive 340mm shocks with 70/120 springs, new fork seals and gators (wipers aren’t available in 31mm apparently), shorty sausage muffler, new keyed ignition and a fancy shorai battery! i also got some super big alum dirtbike bars that i don’t really like, so they won’t be sticking around.

once i had the bike running okish, i started to tear it apart. this is how it’s currently sitting on my lift.



my buddy/coworker tony gave me a chain and i threw it on before i got it running. there was no way i was going to ride it around with the stock, mostly rusted solid chain.
he gave it to me because it’s been sitting on a shelf for years as most modern bikes don’t have such short wheelbases as older bikes like the sr. since we haven’t been able to sell it for the last 10 or however many years he’s had it sitting on a shelf, he said if it fit i could have it, and it fit perfect! i only had to cut one link out! also, look at that wacky sprocket.

i’m going to build my own wiring harness, mount the ignition in the frame under the seat, probably chop the frame off behind the shock mounts and weld in a loop of sorts and cut off the passenger peg loops and other tabs i won’t be needing.

i have a mikuni vm32 on the way to replace the leaky stock cv unit. i’ll probably be running a uni filter because, while they look cooler, k&n filters suck. the carb, filter and pipe will be all of the “performance” stuff i’ll be doing to the bike, and i’m only doing that stuff out of convenience.
the stock aribox is ugly and takes up the whole under-seat frame area.
the stock carb is leaky and will flood the engine, even after adjusting the float height and replacing the needle. rebuild kits aren’t available, and while i could buy each piece individually, it would be a pain in the butt. the vm was like $60 new, and it means i get to toss the cv carb. i hate cv carbs.
the stock pipe is rather rusty, and has a goofy pancake muffler that takes up the space under the swing arm between the rear tire and engine, the space where i want to relocate my battery box. i am, however, reusing the header.

i cut the baffle off just past the weld, making sure not to cut all the way through.

my cheapo jcwhitney muffler fits perfect!

i mocked it up on the bike.


i think it looks great, and gives me the space i need under the swing arm for my battery box. i’ll probably paint the pipe in bbq black, masking off the muffler cos it’s shiny, and maybe put some red inside the muffler. we’ll see. doing the pretty stuff is a long way off.

i mocked up the general tank too, didn’t get pictures though. i have some interference with the frame and the tank tunnel. not sure if it’ll be worth the work to get a general tank on there. it would look perfect, though! just the right size. we’ll see!

68 yamaha trailmaster 80

a week or two ago i traded off a stock honda hobbit moped for this 68 yamaha trailmaster. the guy thought it was a trailmaster 100, and since he told me it was i thought so as well, but after doing a bit of interneting i discovered it’s actually a trailmaster 80. i was a bit disappointed, but what can you do?
besides, it’s a rad bike!




it fires right up with kickstart or magic button, and i was able to go up and down the alley with it ok. it runs well, but shifting was tough. not sure if it’s due to the nearly-seized clutch cable or if it’s going to need a little clutch work.
it goes through the gears easy enough, though, so i’m pretty sure it’s nothing catastrophic.

i’m not exactly sure what i’m going to do with this yet, after getting it sorted.
part of me wants to cut it up some and make a little city ripper out of it.
it’s in great shape for it’s age, even though all of the silver bits have been rattle canned, the carquest trailer tail light is screwed on crooked and the whole bike isn’t quite as nice as the pictures would lead you to believe.

but i mean come on, wouldn’t this be a blast?

81 yamaha sr250

here is the 81 sr250 i pickd up for L on the day i dragged it into the shop. bought it from a guy for $250, the bike has less than 2k miles on it and was last registered in 81.



the idea is to strip it down and make it as small, light and simple as possible. L’s tiny, so she needs a small bike to get going on.

really, i would have liked to find her a 125 to begin with, but the sr is a small bike and will hopefully work well for her.

with a carb clean and some fresh gas, i was ripping up and down the ally on it. 30 year old tires and sticky brakes made for a fun experience, and the front of the bike felt like it wanted to twist to the left when i got on the front brake. it’s a total death trap. i love it.

stuff in store-
-strip all that crazy 80’s mini-cruiser stuff off the bike, including the pizza box
-some little mid-rise bars
-low, thin seat
-general 5 star moped tank
-19″ wheels front and rear
-some long shocks out back
-gunna try and reduce travel and height in the forks when i rebuild them (as you can see, they were already pushed way up into the triple trees to make them lower)
-little moped headlight
-aftermarket muff on that pipe
-vm mechanical slide carb (hate cv carbs)
-and more!

(_shitty paint mock up_)
this is going to be a super fun project.
