I came home tonight and found this rad beast in my garage. Its a magnum thats been modded to hold a huge battery pack and electric motor. All the moped elements are there (pedals, MikeThomas disk, freespirit seat, 5 stars) and it look sick. I guess it belongs to one a friend of my roommate, but they left and its past my bedtime, so the specifics will have to wait until my next encounter. In anycase though, wow!


whoa what happened

I don’t know what happened, but here I am. Back from Reno, living the dream right now. On the topic of reno, it was pretty rad. I liked riding mopeds around and meeting cool peeps, but my pipe mounting bracket decided to snap so I had to rig some fencing to hold it on. After amazing clutch blasting and the broken pipe I decided it was time to change the fluid and switch pipes. Fluid was black, now I have some fresh synthetic 10w-50 in there and its still slipping like a dream, but with the n8p it needs to be geared shorter. Also, its really freaking loud, but the cop I rode by didn’t seem to care.

Check out the custom clutch puller. Also the perfect clutch shoes.

Here are some photos of my trials today. The heat is gone and it’s nice out, so now I can hang out in my shed without dying. I’ve got 2 projects in the works, if one of them actually comes together be ready for the craziest bike ever?

Oh yea, got the G3 running but it needs a choke and some type F. It sure looks pretty though.

Finally, if you haven’t seen Fast 5 yet, GO NOW! Saw it last night and wow, it was way better than I expected; almost as good or maybe just maybe better than tokyo drift. You be the judge.

I got home and was really wanting to go ride around, and of course all my bikes except chappy are broken. So of course the best option was tearing chappy down (stole the master link and the head), and got the old magnum running (I also stole the pipe from my pinto, which runs- well ran, but has bent rims). Its the old polini, with a head gasket, selettra, mikuni and so on. It fired right up and ripped. I raced sean around town and it only got up to 340 so I think its fine. Unfortunately the clutch is on its way out. I knew the pads were chewed up, but I think the posts are now bent or something because sometimes it slips and works like a dream, and others it grabs way to fast and is a turd. Regardless, its nice being back on a fast bike, at least for a little while.

We also went to the archery range. You may remember me posting about this gem awhile back, and its really fun. We started with 18 arrows and only lost 4. Pretty good for a bunch of newbies. Check the rad pics.

Hey look, a moped!

Matt’s Moped Madness

So I was moping the other day how I have 12 mopeds in my shed and they are pretty much all in a state of disrepair, but fortunately most are fairly straightforward projects and I have most of the pieces to get them done. The key element I currently lack is time to wrench.

Now on the other hand, super-cuperteen, mr. matto, has a lot of really big, mostly very scary projects. Matt came from building race cars and has been a life-time tinkerer (lego constructions consuming rooms, or so I’m told). His first moped was a Puch AD, but he quickly dropped that and built a mean old magnum.

You’ve seen it in old posts, but this bike really is impressive. It wasn’t quite so pretty when it first hit the streets back in 2008, but it was FAST. Remember back when Tommy hit 70 on his metra 80 magnum? That was back at the Mopedheads first rally, and Tommy was gps’d, but Matt was not. His motor has survived every rally since (except Seattle and SF where he rode Gerbi) and it has been right up there at 70 the whole time. The MB-5 wheels and forks make the bike a beast, but whatever, it goes. I wish I had some original photos of it with the simo and hero-gizmo tank and uncovered seat. Not nearly as nice, but still fast.

Like any builder progression is natural. We all got excited about Derbi motors a few years ago, and after I got my original variant, he put a wanted ad on MA and got a real nice flat reed motor for $100. He built it up and was out on the track at the 2nd polini cup. It was fast but it seized due to a pinched fuel line. He wanted something cooler so he grafted the motor and swingarm onto a Garelli SSXL frame with the help of one of our buddies, another dude into building cars. You’ve seen this bike and its been equally as rad. Its loud and its fast. Its also reliable, that is except for cracked seat mounts and just recently a blown seal.

Now his new projects continue the ingenuity. Another Gerbi, this time a piston-ported giladerbi has been made to fit another SSXL frame. Who would have know the mounts all align perfectly, just the cases need some trimming?

With the help of Tom and others, he is building a 50cc moby. He was going to go the whole GR1 route, but some creativity means a stock crank and cases pumping out 15+ hp. Its obviously early, but it has potential.

We all got into the mini-moped dirt-bikes a year ago, and he followed suit by picking up this rad pink magnumX frame. I don’t know what he wants to put on it, but I recall hearing about cheap monoshock swingarms and rad pitbike forks.

Also seen on the boards is his AR50. Much like the AR80, but with less displacement, this guy is rad. It has slicks, race-ready rear suspension and a cool custom seat. He showed me an English site that has big kits, CDIs and pipes, and how the power will far exceed that of an AR80. This is a blast to ride now, and it’ll be crazy with some more power.

Lastly is this death-trap he is constructing. I want to say its a honda frame and some big single cyliner 2 stroke. Apparently the motor will put out something like 30 horsepower and should weigh in less than 150 lbs. He has a cool fiberglass tank and other bits. I don’t support this, but its cool nonetheless.

Yep, Matt has a lot of bikes. All are rad and constantly pushing moped tech to new levels.

Got the beast running today. We had some little troubles with a bad head gasket then the wrong base spacing, but we got it all dialed in and it fired right up. Runs like a beast! Pretty quick, especially for a 12.12 sha. I can’t wait to get something bigger on there. We have some minor things to do still, but basically its all there. Score!

Sean got his new build fired up and its looking good. Obviously need some more little things, but hey, almost there and it sounds great.

Return of the Magnums

I built this guy about 2 years back and its for sale yet again. The first dude who bought it was really cool and did a few things like new shocks, painted and added the sidecovers and rear trunk, as well as some other misc. additions.

I’ve always really liked this build. The Nostalgia rims, custom ebrs, and a super reliable e50 made this such fun bike to ride. I sold it for quite a bit back during the big moped market, and each time the price goes up a bit. I’m glad to see its still in such great shape. There are little things I’d change now, but its so simple and clean.

Unfortunately this dood, what I consider the nicest bike I’ve built did not suffer the same glorious fate. This guy never made me happy in its handling or performance. Tom bought the frame, the motor went to la, and other misc parts have found there way onto various builds here and there.

Somehow my slightly ratty magnum with a 2 speed and mismatched parts has remained my favorite. Its always been the most comfortable, performed the best and been a lot of fun. I always wonder when it might be complete. Still gotta figure out how to hide the EBRs and get my dash mounted up. One day…

busy day

So the weather is just about perfect right now. Sunny with highs in the mid-70s, and everything blooming and green. No dead grass or fires yet. Matt and I decided to hit up the archery range for a few hours and hit some targets. We aren’t that good, but whatever, its still fun

The hanging targets are the most fun.

I pretty much got the magnum done. Its not quite tuned yet, but the seat is one, tank secure, HPI on and kind-of timed, and mikuni and intake done.

Everything went pretty well. I just used my derbi intake, but drilled new holes so if came off to the side for the mikuni. I think this was the first time all my holes lined up the first time. Seat brackets took a few, but the freespirit seats are actually really close to mounting up on magnums. I bent the rear bolts out just a tad and built quick brackets for the front. The derbi tank is a tad wider than a magnum tank, so I built up the rubber mounts so it didn’t move around. I know the lines aren’t perfect, but I’d hate to rip up my perfect seat or dent/scrape my ltd tank, so it will have to do. The riding position is actually quite nice. The red bike theme continues

While working Bro and Matt went up the hill, Matt to ride his bike down (drivetrain missing), and Bro to longboard. This hill is awesome when everything works right, but speed wobbles are not good. I lost my brake once coming down and crashed into the bushes. This time Bro’s hand and elbow took the brunt of it.

Putting the HPI together was quick and easy, just the first time I didn’t tighten the nut all the way down so the flywheel came loose on the first test run. I’ve got it set just about 2mm BTDC and it seems pretty powerful. I’m geared 18×36 and it gets up to speed a bit quicker than it did with treats CDI and the phbg. Top speed somewhere close or at 60. With some tuning and shorter gearing it should be pretty good for the track. I really prefer top tanks over step-throughs when it comes to riding as its so nice to have something to hold onto with your legs. So while this thing will be nowhere near a contender, it should be a lot of fun.

Finished the night off with some tri-tip, guacamole and jalapenos. A busy, but very fun day. This kind of day makes me very excited for summer.

Whistler in the morning. I’m bringing the mini-camera so I’ll take so pictures and update (sorry for the crappy pictures, this camera sucks in low light).
