We had contacted Randy Ashlock at CPI a few months back and inquired about a possible race bike to compete in the Pacific Northwest Scooter Racing Association using CPI's GTR 50 as our platform. Here are some pics of just how stout a frame the scooter employs. We even noted that the tail section is already pre-drilled for a bench seat! We'll be installing an SIP 70cc top-end kit (nikasil lined sleeve and ceramic coated piston) and doing some other work to the bike soon. We're hoping to achieve between 24-28 hp when we're all through. We'll keep you posted!
De-restricting the Sachs MadAss 50 (electronic governor extraction):
You can expect to see a 7-8 mph top-end gain following the removal of the electronic governor:
On the automatic
49cc MadAss:
stock speed = 29 mph / 46.67 kph
derestricted = 36 mph / 57.93 kph
On the 4-speed
manual 49cc MadAss:
stock speed = 29 mph / 46.67 kph
derestricted = 37 mph / 59.54 kph

1- Electrical stuff is hidden away under the rear of the frame by the rearwheel. |
2a- Start by removing the four phillips head screws that hold the battery cover in place. |
2b- Continue removing the phillips heads |
|
2c- Keep going at those screws! |
3- The battery cover will slide down out of the way. |
4a- Three 10mm wrench size bolts hold the upper electrical cover in place, so get those guys out of the way once the battery cover is off. |
|
4b- Your gettin' it! |
5- The electrical cover slides out of the left hand side of the bike with a little bit of effort. |
6- Once the cover is out of the way, Voila! Electrical mayhem. Try not to unplug anything you don't mean to. Yes, there is one stray connector that doesn't hook to anything. Don't worry about it. |
|
7- The object you're looking for is located top and center of the blob of electrical bits. The ignition coil itself is larger than the limiter and has a green electrical plug on it. The limiter is a black box approx. 1" X 2" X about 3/4" thick. It has some letters on it that read: DIAN HUO QI. |
8- Once you get the two pieces kind of pulled away from the blob of electrical stuff, you can see that the harness plugs into the limiter, which in turn plugs into the ignition coil. |
9- Start by unplugging the limiter form the harness. |
|
10- Now unplug the limiter from the coil. Remember the coil itself is larger and has a green plug on it. |
12 - Now plug the coil back into the harness.- Put everything but the limiter back the way you found it.- Put all your covers back on and enjoy speeds greater than 28 mph! |
The 2005 Portland Adult Soap Box Derby, Team Eurotrash:
Ptown Scooters is proud to help sponsor Team Eurotrash's last minute entry into the 2005 Portland Adult Soap Box Derby being held this Saturday, August 20th at 10 a.m. at Mount Tabor Park (SE 60th, between Belmont & Division). Team Eurotrash 1st made their appearance in last year's derby and placed an astonishing (well - we think so) 17th out of 34 cars and even survived the dreaded Gauntlet Run.
So c'mon down to Mount Tabor this
saturday and cheer the team on and be sure to swing by the
Oregon Scooter Club's food stand for some yummy eats and cool drinks. And
don't forget to pick-up a Soap Box Derby t-shirt screened by Modified.
So what the hell is tucked away under that pretty paint you ask?
Update 05/10/06: "The 5-speed transmission failed horribly. Went to an EFL P200 unit (4-speed modern transmission)." - Steve

Bio-Diesel
Vespa Project:
Loren Fennell of the Oregon Bio-Diesel Workshop LLC called-up
PTown a couple of months ago wanting to know if we'd be interested in trying
to get a Vespa to run on his mixture of bio-diesel. Patrick thought it would
be pretty cool to give that a whirl. In early April '05, Loren came by the shop
with his mixing jars, notepad and cans of fuel ready for round one. "Smells
like chicken" was heard around our shop numerous times as the engine was
fired-up, another of Loren's mix ratios scribbled down, adjustments made to
the jetting; it's an ongoing project but we're pretty sure that Patrick's knowledge
of the two-stroke engine and Loren's ever expanding list of fuel mixtures will
turn-up a viable bio-diesel powered Vespa.

Patrick's Lambretta Chopper:
"Why would you chop up a Lambretta frame?" I think
the assumption this Spring Scoot 11 participant was making is that Patrick started
with a "good" frame. I don't think that was the case. I recall our
friend Peter Dixon beaming when he popped into the shop to drop off his freshly
welded front forks. Long was all that came to my mind. And hard - the bicycle
seat Patrick had mounted to the bike when he roared into the parking lot at
Prescott Park for the sat. bbq at SS11, well I think he went through a tube
or 2 of Prep-H that weekend.
