NYC Streets vs French Pipes!

I took The Green Machine out for a couple of rides and its running even better than before! The NYC streets are still essentially the surface of the moon (why are my taxes so high?). I’ve heard of Doppler silencers falling off but never expected it to happen on a busy street! I pulled out, the bike hesitated, and then I was riding a monster chainsaw!!! I pulled over and turned around just in time to see the guts of the silencer hit by a car! Great!. Then as I pulled out to go get that part, the actual baffle cylinder got launched another direction and promptly squished…

NYC streets 1 Doppler welds 0!

After getting back to the garage it was time to rebuild this thing. Two hours of hammering things back into round, grinding off bad welds, and I was almost there. Luckily, my garage is next to a motorcycle shop who’s owner is a great source of info/and he welds! So the 3 spot welds were replaced with one nice weld the whole circumference of the baffle mounting plate. A little repacking of the baffle material and some M6 nuts and bolts and I’m back in business. Screw you NYC roads! This thing is solid!

PS..it broke off again…I’ll need to re-engineer this thing…ugh.

The Return of the Green Monster

I’ve finally found the time to assemble the Gila + Polini cases engine and with a little bit of this…
20120304-130303.jpg

this case should be sealed up tight!

I wanted to use the Polini spring that came with the cases but I’m sans the hardware to mount to the case. I cut up an old 103 engine mount and created a mount myself. It ended up looking pretty good but I have no idea if it’s putting this mount in the correct location. I’ll have to see when I get out to the garage…I’m guessing it’s a tad off…hmm20120304-130802.jpg20120304-130820.jpg

I’ve never used a launch level but it sounds like fun and it comes with the case so what the hell!

Next up add my trusty Multivar and the old 2 coil points. I’ve heard horror stories about these points but I’ve never had a problem (other than some flywheel slipping) so I’m going to run these until they self-destruct. 20120304-131116.jpg20120304-131128.jpg

I have to get better lighting in my work space. These pics are a bit dark…sorry about that

At the garage it quickly became apparent that the Polini spring is not going to work (crap) I was so ticked off that I forgot to take a pic of the mess…I need to look at some cases to see how the spring fitting/exhaust mount fits/looks so I can copy a set. Until then then the launch lever is coming off and the old Doppler spring is going back on…I have another lever somewhere that might work…I just need to remember where I put it…

I can wait on the launch lever so I decided to button this project up!

Gave the moped a push an it started right up. It’s still a bit rich (95 jet) but its still pretty cold here in NYC so I’ll leave it alone until April.

Bring it Spring! I’m ready!!!

Same Old Kit. New Monster Case!

Well I said I was rebuilding the Green Machine’s engine and so it begins. After being lazy and bolting together the Gila power plant, the original seals made it a year and a half before giving into the high compression. This failure was totally my fault too. (note to self — riding dubs on an air-cooled moped on the hottest day of the summer is not a good idea)

The kit, piston and head look perfect and I had this Polini race case just laying around so what the hell lets get to building!!!

FAG bearings and monster transfers, this whole setup should be a bit more durable than the stock cases, more or less.

I’m going to smooth out the transition from the case to the cylinder transfers. I’m just trying to make the transition gradual as I’m not looking to add the giant transfers to an already smooth running kit. So mark it up.

Grind away the excess…

Next up bearings, seals and closing this thing up!

Green Machine (or John Deere’s moped)

My favorite moped of all time is a Peugeot 103SP in green…any of the shades of green! After riding Jeff’s from sHs I wanted a French variated moped but I just figured they were had to find. I was skunked twice on Craigslist deals in the Pittsburgh area and mostly gave up looking. Then the move to Brooklyn happened and having no job was a great way to keep me with only one moped.

Once a job was acquired I was always looking for a 103SP or a moped with a Minarelli (I wanted to play with the 90cc kit). The Orphanage had exactly what I wanted but not anywhere near what I could pay. I’d saved the picture as a benchmark for my search but nothing turned up. Then I found an orange General top tank in nice condition, so I picked it up.

I bought some new tires and set to work stripping and cleaning the moped. Winter struck and the NYC moped scene slowed down (except for a few of us who where thermals under our jeans as we are nuts). I then started getting mystery text messages about someone lusting about my General. Little did I know that Cliffy wanted one more than me!

I was picking up tubes from the Orphanage and while talking with Ryan mentioned that I couldn’t believe the 103SP was still there. I was sitting on it imagining when I’d get one. To my surprise Ryan asked what I’d pay. I apologized ahead of time as I knew my offer would be low and then Ryan said he’d take my offer! Yay Orphanage! I paid for half on the spot and called Cliff to sell the General.

In the mean time we were asked (M23) if we had some mopeds for a commercial but everyone we new only had mopeds in parts (winter rebuilds). Eric’s Magnum (The Great Snack) was running and to get a second he made the final payment on my 103SP. So I hadn’t even had a chance to ride it and the moped was crossing the Williamsburg Bridge. Eric did send me this:

After the shoot the Green Machine was safely parked in our garage and I paid Eric back for the rest of the bike. I’d started on Tomonstr but was still in search of parts so I began making som little adjustments to make the SP’s seating position perfect.

A quick ride around the block made me realize I was almost there but the seat still wasn’t quite right. I kept the SP engine stock for a while while I began absorbing everything I could about variators. Luckily I’d seen how they worked in sHs and Pete had built a fast 103 in M23. So outside of the Sparta sidetrack I began building my dream machine.

70cc Gila kit, Malossi 70cc Hi-Comp Head, Doppler Spring, Doppler Pipe, 21 Dellorto PHBG, Polini 2 pedal reeds and Malossi Multivar. With a little case matching for the third eye and some tuning this is, in my opinion, the most bulletproof Peugeot setup you can build.

[Keep in mind a 50cc water-cooled setup or even 50cc air-cooled engine can create a ton of power but it’s all happening at crazy rpms. So once you leave the land of stock, pick what you want to replace more often; Hi RPMs wear top end parts faster, Bigger displacement wears bottom end parts faster…either way shit breaks…welcome to mopeds ;-)]

Well I just finished it in time to ride it for M23s rally. I was going to wait to tune it but the weld holding Old Blue’s tank on broke and I needed a ride…

Well stock gearing (12×56) made this thing a wheelie machine! I was expecting quick not “oh shit the front tire is off the ground again!” The moped was running great but the seating was still not quite right. Time to make a new seat mount up.

20120129-174621.jpg

Seating solved + gearing and suspension tweaks and the Green Machine is perfect!

Specs:
70cc Gila Kit
70cc Malossi Hi-Comp Head (decomp plugged)
Stock Cases matched and third eye added
Polini 2 pedal reed block
Delloroto 21 PHBG
Doppler Spring
Doppler 70cc pipe
Malossi Multivar
Stock 2 coil points

This build made it for over a year and a half before the seals blew out. When i opened it up everything still looked new! So now it’s rebuild time and this time I’m starting with a polini race case but that’s for another post…
