It looks like the can comes off the pipe to change out the rear wheel, that's a plus.
I got an email, must have been translated from Italian, 220 euros ($300 Canadian) plus shipping and I imagine duty and if ups is involved an extra hundred just for them. I want it but don't think I will be able to afford it at the going rate of escalating costs. Looks nice though. Does it offer any performance gain? Does it rob any performance? How does it sound? Once I know these things It might be easier to find the money somewhere. Mega. |

Webcamshafts is the best place to make a camshaft,i trust them. Peak valve lift: stock= 7.154mm=.281" mine(reprofile)=7.735mm=.304" webcam= 7.365mm=.290" As i see,webcamshaft's paper doesn't show at how many inches of valve lift they count 264 degrees of duration but i feel that this is a very hot stage 3 camshaft. |

The grind number is probably used on a few different engines, but they may respond to an email or phone call about availability if this Vespa dealer used to get them made in the past? |
Hi guys, I am a happy owner of Piaggio x8 125cc. For myself it's a great way of transport. I mean enough space to fit everything I need, comfortable (maybe too comfortable
![]() ![]() Any input is highly appreciated. Thankyou! |
Project report:
12,000 kilometers and six months later everything runs fine. Valve gap,belt,transmission,clutch,carburetor and engine's sound are okay. Camshaft has no sign of wear. I just made two oil and filter changes,i replaced spark plug and i washed the filter pod with water and dish soap. The malossi piston now is running free in it's cylinder and the scooter is very fast,maybe faster than it should be.

AFR (oxy sensor bung)

Ask here:
info@turbokit.net <info> OR tig weld an O2 sensor bung as i did on my akrapovic. ![]() ![]() Without silencer,it sounds like a small off road thumber. |
NIce job
DROOL!!! AKRAPROVIC nice pipe. (think I spelled that wrong)
That welding job is very nice, im not the welding man myself but I know it SHOULD look like a stack of pennies covering each other. yes that was my original plan. I have 2 spare bung things in my shopping cart with the oxy sensor n the gauge. and awesome, im sure it must sound like a hot pitbike with that thing outa the exhaust. |
IGNITION CDI
I had to do do something with the rpm limiter. Camshaft after reprofile,the bigger valves,big carb and ported head ask for more rounds per minute to give their best. I was thinking about using the cdi from LXV 125.It's a watercooled model with 4 valves and as you can see on the left table,it has the limiter at 10700 rpm instead of 8900 rpm of et4-lx150. ![]() This is how looks the magneti marelli 486954 from ET4 150 ![]() ![]() And here is the lxv 125 cdi.It seems that is a bolt on modification,the plugs are the same. ![]() But if you compare the advance tables at the first picture,you can see that ET4 150 has maximum advance 26 degrees and LXV 125 even lower,at 23 degrees. These prices are not enough for me,i want about 30 degees maximum advance to match with my camshaft. Last edited by dynagrego on Tue Nov 19, 2013 2:44 pm; edited 1 time in total |
I had to take a risk.
Malossi sells a cdi for 4valve watercooled leader engines.It's the 5512341 model vor vehicles with immobilizer. http://www.malossistore.eu/Prodotto.aspx?type=M&&C=5512341&Search=si ![]() I asked from malossi infos for that cdi,such as advance curves,about custom programming,etc but never came an answer. I found a special price on ebay and i ordered it.Many days with suspense passed and finally: YEEESSSS,MALOSSI DIGITRONIC 5512341 WORKS PERFECT ON LX-ET4 AIR COOLED LEADER ENGINE. I said goodbye to rpm limiter(11000),there is no signs of detonation from excessive advance,i have even my turn signals work! It is bolt on,just unplug the old and install the new cdi. It also removes the immobilizer. Engine pulls hard,i have now to connect my rpm gauge to take some measurerments according to gps readings |

scootermarc69 wrote: I am confused. I though you want the ignition to retard as rpm rises. Can you explain? If i could make a personal advance table,i would set a first step of 26 degrees from 4000-6000 and a second step of 30-32 degrees till the end using good fuel. Of course,the best way is to set the ignition timing on the rolling road using several steps of advance timing but i think malossi cdi is not adjustable. I filled several times the form below,but malossi doesn't answer,maybe they are dead. http://www.malossistore.eu/contact.aspx?Product=5512341 |

Is it a 2T v 4T thing? Clearly this product I purchased for my 2T Vespa shows ignition retarding as rpm increases.
http://www.kytronik.com/sb |
2-stroke and 4-stroke motors have about as much in common as they each do to diesel motors. Not much!
This may explain 2-stroke timing requirements better........... http://www.dragonfly75.com/motorbike/timingcurves.html And believe it or not, this Wiki isn't actually half bad......... http://en.wikipedia.org/wiki/Ignition_timing Hope it helps a bit. |

Carb Help Needed
Thought you folks may have some ideas.
We just put a Liberty 200 jug and PM Tuning pipe on my Fly150. Bike started fine, ran smoothly but power no where expected. Carb had not been touched except to remove for motor work. Pulled the carb to check. Found the slide was not moving freely. The slide spring appeared to have gotten wadded up. Testing with a shop vac would only move the slide half way. Diaphragm looks good. Carb was functioning as expected prior to this. Bike was falling flat on its face after re installing wouldn't go more than 20mph! Any ideas how to sort this out? |
