Hey John,

Guess What!

I've been keeping track of the last couple tanks and i can say its around 40mpg.

I took a trip out to Westlock this morning, 130km/h was do able, but its pushing alot of wind around, cuising around 110km/h was much nicer.

The only problems is, i broke it already.

On the way back from Westlock, i came in on Hwy 2 into St Albert, after slowing down from 100/110 to near 80, i lost all compression. It didn't feel like a seizure nor did it sound off normal since i was reved up in the power band.

Now i get to try to find the time to rip it appart to find out what kind of damage i did.

Sigh, been there, done that, didn't even get a t-shirt. I hope that it is something minor.

40 mpg! Nice to know someone is doing worse than me.

See you tomorrow?

Sounds like you might have top end problems. Check the Cylinder head or maybe there is a hole in the Piston. I hope it's not that serious. Lambretta's are not known for handling long runs at High speeds and that sounds like what you were up to today. That's why alot of guys that like going fast have moved to nicasil lining to disapate the heat quicker. I hope to see another Lammy on the roads in Edmonton.

Cheers

Took it all appart this evening before the storm rolled in. Ahh just in time.
Shock out, boards off and bump stop up. Just enough room to get everything out while still in the frame.

NOT FOR AIRCRAFT USE LOL
Like i was going to use it for that.

An indication to what broke. HINT: Its mostly likely a part that comes really close to this.

Ooh, Ooh, Ooh, i think i see whats wrong

Angelo, you get the cookie

John and others,
If the piston slag and carbon crap comes off and cleans up, does anyone think the barrel is salvagable?
Of should one chalk it up and get a new one.

Can anyone suggest an easy way to get the wrist pin out of the piston and connecting rod without using another wristpin and a hammer?

The engine is still in the frame and i would rather not hammer on stuff if i don't have too.

Is there some sort of puller i can acquire and use?

OUCH!

There is such a thing as a piston pin puller but I have never used one. I use a 3/8" drive deep socket. Hold the piston in one hand with the fingers curling around to hold the socket as well. Now tap out the piston pin absorbing the shock with your hand.

You could also sneak Cathy's hair dryer out of the house and heat the piston up. The pin would probably just push out then. A propane torch would work as well.

Melted slag is not a problem as that will clean up with a quick hone. Just as long as there aren't any deep scratches. The rule of thumb is that if a finger nail catches then it's toast. That said, one or two may be livable.

Kevin,
I wish in this case that I was deadly wrong

, really sorry to hear of the Detonation. I was hoping that it was something simple like a loose spark plug wire or something, but that is only a common problem with modern machines

Cheers
Angelo
