mopeds


my favorite mopeds (off-road)

As I’m sure many can tell, my favorite mopeds are those of the “off-road” variety, I.E. my C5, Magnum X, my earlier desires to build a rhino-lined trails maxi, my love of the Motobecane VLX, Derbi TT, RD50, and Sean’s Tomos TX50 Super Tom, and others I am probably forgetting.

Well now look at this bad boy some fella in New Jersey was trying to get more info on:

The Peugeot TS Enduro (aka the TSE). I know nothing about it other than holy crap this thing is awesome. 103 motor/swingarm, MX bars, what look like a 17 rear and 19 front tire, beefy forks, an upswept exhaust, and of course beefy skid plates. That and some rad tank decals; this thing is really awesome. Oh, and don’t forget this one is mint. This looks like my cobra did, under an inch of dust, sealed for the day it hits california sunshine. If I didn’t have a shed full of mopeds and did have a job and some money, I would be on my way to New Jersey and ride this thing through the trails of AMERICA back to California. Damn, one day.

I mean look at this beauty:



Derbi Day

Today was a busy day getting all my derbi junk together.

Tony hooked it up with pretty much all the plastics, controls and other bits from the revolution, the complete revolution motor (which someone managed to strip in one of the swingarm bolts and cut off the head, extracted it wrong and drilled a new hole at an angle to hold it together, wonderful!), the revolution wheels with new 2.75 Pirelli ML75, Rev. shocks, the messy pyramid reed motor (missing clutch, variator, cylinder and head), and a ducati cdi stator and flywheel. Oh yea, also a spare new revolution crankshaft. So yea, quite the collection.


First order of business was comparing fitment of the revolution motor in the c5 frame. Obviously its going to take some work but its not too far. A fellow down in the LA area put a Flat-reed motor on his rd50 (same frame) and basically had to modify the kickstand/motor holder and add an upper bar to support the upper/front bolts on the case. I’ll be doing much of the same. The rear holes in the mount will need to be slightly modified but beyond that it should all fit very well.

Here is the frame with the original piston port and another with the start motor. Kickstart lines up perfectly!



To keep everything simple to work on I will have to drill out the stud holes in the cylinder and head to fit the funny c5 mini-studs and bolts. All easy. Much of this will be on hold until school is up in may. So yea, just getting excited about what is to come.

To keep things complicated I’m going to be putting together another derbi with the help of Matt who has a really spiffy green Variant frame. We are going to build it mostly as a loaner for friends or us when all our stuff is broken. The setup will be simple, piston port bottom, stock cylinder bored out to 60cc, homeot 4p, milled flat reed head, tjt, malossi clutch springs, 20×30 gearing, 19phbg, revolution mags, and so on.

Tom had this cylinder on his Variant a few years ago and hit a hair under 50 with an estoril with a janky header. So optimized it ought to be a pretty rad bike that is decently reliable and quick. I’m going to try and get most of it together tomorrow, but I gotta switch a water pump on the diesel first.

Lastly, here is the nasty pyramid reed. Crank actually turns pretty well but it sure is crusty.



derbi factory

Tom has a lot of derbis. Yesterday we BBQ’d and I saw most of them: Senda, GPR50, Revolution, C5 diablo, Variant SLE, Variant TT, and probably more. One was in boxes, others apart. Also a few frames designed for flat reed motors, including a hobbit and a grande. No pyramid reeds and I didn’t see a flat-reeder, but that doesn’t mean he doesn’t have one. Its a pretty sweet collection. Once my c5 is done we are going to wreck havoc.

update: now he has a laguna. Collection complete





In less exciting news, progress has been made with magnumX. The top end is on, intake there, carb and controls solid, so now the fun part of making a pipe fit. The only setup will not clear unless I want to pull off the pipe everytime I change the plug. No thanks, so I’m going to have to get crafty. I might play around with it thursday. I think sean is getting close on super tom, so mini-bruisers are going to be rolling soon. The cuperteens are also on lookout for a fleet of the coolest bikes ever. Check out The Stand for a preview.

Also, I didn’t go racing. It was hot, I was tired, and I didn’t think anyone would be there, so I skipped the 5 hours of driving and $50 race fee. Next time we are going to try and be there, hopefully others will show as well.



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!



boston built diablo

that may not be entirely true, but a few very generous Bostonians are making my diablo build that much better.

KHZ Daniel was very kind and sent some sidecovers my way. Handybikes was only selling the right side cover, so that was no good. I emailed Daniel regarding his spare covers from his amazing diablo build, and he was more than happy to part with them and send them my way.

Old mopedhead Ben, now a boston resident was also very kind in lending to the power supply of my derbi (possibly unknowingly at the time). Some kid bought his red Maxi N with a metra 80 and proceeded to seize it very soon after. Ben thought the cylinder was dead and sent it to me, giving me a shot at its rebirth. I’m pretty confident it will blast again.

So the c5 is slowly coming together with the help from many. I still need to order a few more decals and other misc. bits from Handybikes, and I also need to find somewhere to get the seat reupholstered (as well as flatten out the seat pan). So while its coming together slowly, the project is moving ahead. Seals are in route for the motor, but the crank is still a situation. I’ll figure it all out soon enough.

was pretty rad. I finished midterms, so i headed home for some cupertino debauchery. We hit up a bar, some people blacked out, someone woke up in a closet, we went bowling, justin was a newb “no my stator isn’t spinning. Oh, its loose”, had a smokey bbq, and all more. I tried to jump a curb on magnumx, but instead planted my balls firmly on the tank. not fun.




magnum x is tiny

new toys. a35 is going to go on the swinger. freespirit will be rad for april.

its coming. Pickup this weekend! I’m going to sell the swinger maybe now, maybe over winter break, we’ll see. I’d probably rather do it later with some spokes. Vespino will go when the times comes. So stoked! Me and Tom are going to be C5 buddies. I’m super pumped! I’m not sure exactly what will go on it or how it will turn out, but I’ve got a few big kits so the options are there.

This is a boston c5. I don’t think mine will be quite as pretty, but whatever! Photos do not do size of the bike justice.

an aside: all my bikes are red, or at least partially red. Why!?
