Dirtbag Challenge

Today Justin and I went to the Dirtbag Challenge in SF. The premise is you get 1 month and can devote a maximum of $1000 to building a rad motorcycle. On the day of the party you gotta ride your bike 100 miles then do a bunch of burnouts and stuff to get people to love you. I’m not sure what you get for winning besides a cool trophy and a bunch of new friends, but I don’t think it matters. All in all a cool event. I felt extra cool arriving on the back of Justin’s scooter.

The scene was madness with tons of rad bikes, custom contraptions, burnouts, wheelies, stoppies, and crazy motorcycle folks. It was loud, smokey and quite exciting. We saw Terry Dean and Paz there along with another Justin from the sunset. Here are some pictures of it all:











Oh yea, check out the scooter gang doing laps around the circle by my house. So rad!



magnum stuff

So hopefully you say gabe’s awesome polini guide, and I thought I’d show you mine. I’ll be honest, the quality of my work is subpar. The exhaust port is nice, but the intake embarassing. Regardless, it runs really well, and its done stupid speeds, and It’s going to only get dumber.

In the cylinder (exhaust raised a lot, widened a lot, intake opened completely) The little scuffs, one at the rear of the port and the other 2 in front were me not good at using a dremmel.

The intake, again opened up all the way, and I filled it a bit with JB because the malossi 4-petal has a lot of wasted space in there

Transfers opened up just a bit. The most important part is opening up the upper transfers. Plenty of meat on the cylinder, so its un-tapped potential. Also, remember you MUST open up the outer portion of the exhaust port to to actually match the flange of your exhaust. Polini’s are tiny, just a bit bigger than stock, but much smaller than 99% of expansion pipes (except proma circuit, they are a perfect match).

Paz originally built my ZA for some other fella in SF. He didn’t go super deep with the upper transfers, but everything is nicely done. A roller rod was pressed in at the same time. The crank has 2k+ miles on it, so super solid!

Thats my ugly polini. I’d like to get another one in the near future as I worry this one may be slowly heading out. It was seized before I bought it, and there is now a fair amount of discoloration on the nicasil around the exhust port. All the cross-hatching is gone. Compression is OK, but not as good as it could be. That, plus I’d like to re-port another with a lot more care.

So in semi-related news, I’m going to make this thing rip harder than it ever has. Either selettra or HPI ignition (selettra is a few OZs lighter, but I think HPI has a little better curve), and my flatslide mikuni.

I want to race something come april, and even though this probably won’t be competitive, with the right gearing (N8P forever!) it should have really good pull. I don’t want to scrape up my LTD seat or tank, so I’m going to be using a freespirit pan and my spare C5 tank. That plus my disk brake EBRs. My goal is to have it running and semi-tuned by tomorrow. I’ll keep posting. Whistler from the 20th to 27th!



COBRA!

So after waiting like 2 or 3 months, this cobra is finally mine, in my hands and totally awesome. Now I must first admit, I hate cobra’s. They are weird, bulbous, offensive mopeds with horrible design cues. They threw a huge tank on a pinto frame and added a butt ugly seat on the already stock pinto rack. They simply are not attractive. Now all that said, I’m still super stoked. I got what I thought was a good deal for the condition, so again, I’m super excited.

There is about 10 pounds of sawdust covering this thing, but underneath it all is one of the nicest, well preserved original mopeds I’ve seen (not including First Kick Dave’s amazing pink champagne newport). The tank is flawless, perfect paint, like 3 small scratches (it might be 4), awesome decals, a perfect seat, original tool-kit, shiny chrome wheels, bars, racks, and only 470 miles. When we drained the transmission fluid up in Arnold, it came out looking brand new, even though it hasn’t been ridden in years.

The motor has great compression, solid spark, and a clean 14mm bing. Unfortunately, there is some residual ancient gas stinking up the tank. I need to flush it out, then this thing is going to fire up like its brand new. I’m really excited (if you couldn’t tell). I also need to finish cleaning the rims, and dust off the front then just wax it up because I have to, its that nice. More amazing photos will come once its running perfectly later this week. Oh yea, its got an original california blue and yellow plate and registration. Sick!

Also, the other new love of my moped life, a paz’d out za50. It now has my ported polini and proma circuit making for awesome around town riding. Up at last week’s creature ride I was quickest off the line and up to about 30, when Lee overtook me on his racer poopgeout. Sure it only goes 45ish, but its so fun, going to like 25-30 before shifting, shifting on command, downshifting perfectly and everything. so fun!

So yea, you can probably count the 3 magnums in the shed now. The black beauty (4 petal polini, estoril?, powdercoated tank, nos nostalgia rims, etc), the new one from brando, and the other one up on the shelf (soon to be my za50 ltd). I’m going to be selling 2 of them pretty soon, and just keeping the ltd. I’m not sure what will happen with the cobra, but right now I’m going to enjoy my new moped.

Oh yea, I won a flat reed motor for derbi! This has been an exciting week. I’m going to be putting that on my sle frame, I know, mods must be done, then the piston port gilarblowme on the hobbit frame. 2 racers. I need to get rid of some mopeds.
