I will fix case gasket leaks with crazy glue and cinomin...

I will make epoxy hybrid leather brass rubber clutch pads.

I have used a launch lever as a throttle...

You should get off this forum and join hara-kiri .com

Only problem is that there not many second posts.

That’s not a problem, it’s a feature.

You SHOULD shove an egg up your ass and see if u can lay it.

Only problem is a whole carton is needed to keep it from falling out.

If you've mastered finessing a tire on and off the rim then fixing a flat does not require removal of the wheel...

You had to go and give it all away, I mean who would have thought the manufacturer would know how their product was put together/worked? :)

Holy cow! I can't even finesse the tire off the bike. Tried zip ties and everything else. the hand strength just ain't there. I just love this though.

Re: SECRET REPAIR TIPS YOU DON'T TELL TO THE PEOPLE FROM MOPED ARMY

There is a video on the tube of Jeff fredette (motorcycle racing legend) wrestling on and off a set of ice tires and he dies a really good job explaining it, it helped me a lot.

Re: SECRET REPAIR TIPS YOU DON'T TELL TO THE PEOPLE FROM MOPED ARMY

Cylinder diviting has to be on that list. On a serious note I think it just ruins your cylinder though. Also even if you mention something secret, the average mopedder would do it wrong anyway.

HAHAHA! I just did this on my Tri-ped microcar because getting the drive wheel side off the axle is such a chore. I upgraded to 2.50-16 from 2.25-16 right on the stand. It is not so much hand strength as physics and placement of the beads.

Re: SECRET REPAIR TIPS YOU DON'T TELL TO THE PEOPLE FROM MOPED ARMY

This is #2 out of a 5 part series but this dude is an absolute beast. He makes it look easy but these ice tires are 3 layers thick and covered in sharp ass studs, they are the worst tires to mount and unmount.

Re: SECRET REPAIR TIPS YOU DON'T TELL TO THE PEOPLE FROM MOPED ARMY

Don't tighten your head down all the way. The opening between the cylinder and the head allows for a better fuel/air mixture that aids in combustion thus increasing horsepower.

Thanks Captain, how you been?

I did that for a couple of reasons. I'm a sucker for a challenge and removing the wheel requires removing the exhaust. The NC50 uses a crush gasket and I didnt have a spare. I was not about to go to all that trouble when it ran perfectly fine and had zero exhaust leaks. Sold that ped about a year ago. (edited)

This is number one in a series of tips that have taken years of serious moped meddling to figure out. I will slowly disperse them in this thread .

If you have a vespa that will not run ,but seems to have compression , spark , and fuel , remove the cylinder and check the piston ring end gap. If it is larger than .012 on the lower end near the transfer ports the cylinder is worn out.

We have found several vespa cylinders will wear out on the lower half and because of the way the fuel charge is delivered through the tiny crank case on those motors , the pressure is not enough to draw fuel through the transfer ports to the compression side of the cylinder.

Out of curiosity , what is the piston skirt to cylinder clearance when that happens ?

Checking your ring end gap is not vespa specific, but always a good idea anytime you are servicing a top end.

The theory about Vespa's specifically not being able to meter and pump appropriately is just not true. They have great case pressure and with the small transfers have no problem filling the combustion chamber. Even if this were the case, why this would result in a worn lower portion of the bore and not seizure/top end failure, is beyond reason. If it doesn't have enough charge to lubricate the cold, un-stressed lower portion of the bore, it DEFINITELY doesn't have enough to lubricate the high-stress, high-temp portion under compression and detonation.

Linda’s profile has some great tips for moped people.

Don’t know if everyone has seen them.

Re: SECRET REPAIR TIPS YOU DON'T TELL TO THE PEOPLE FROM MOPED ARMY

The secret tip I don't tell anyone, is, "you're doing it wrong," and, "that won't work."

Stack two used crush gaskets instead of one new one.

Id try that but at the time that was not an option.

I have no cause to argue your points , but I did find out the probable the causes of wear.

I was talking to a shop owner who has sold mopeds for 50 years.

He said that its the piston skirt wobble that causes the lower cylinder wear.

My theory on whether the fuel charge doesn't get to the upper is just that , a theory.

Either way , We have twice measured the wear with our micrometers and after installing a better cylinder , the bike starts up instantly and runs fine .

So , what was the piston skirt to cylinder clearance before the new cylinder ?

Did not measure the piston to skirt clearance . .
