It's called normal operation. A 50cc engine only has so much grunt and the faster you make the little engined scooter go the worse the take off will be. :roll:

Too lean, then the piston top got hot on the exhaust port side and melted down into the top ring, stuck the ring and then the ring broke up causing all the ding marks in the head and the top of the piston. Then the ring pieces exited out the exhaust port. You can probably find them in the muffler. Y...

Fuel pump driven by crank, higher rpm=higher pressure, and the 57chevy had mech fuel injection as an option. Many high performance engines were mechanically injected before integrated circuits go cheap. Yeah there sure were. They were not that efficient and were expensive and didn't work well longe...

I bet it could be done mechanically. If it could be done mechanically, don't you think by now at least one of the manufacturers would have found a way to do it? The problem is you can't just use the same fuel charge at all engine speeds. That's why the computer is needed. Also this happens fast, th...

Thank you guys for trying though you answered a question I did not ask. To Clarify imagine two engines one being a small 2-stroke and the other being a larger 4-stroke both making the SAME max HP (not the same displacement). Now which one would get better gas millage? In other words, which stroke s...

I wouldn't put any in my oil but if you must a teaspoon MAX! Cap ful at every fill up helps keep the carbon buildup down and varnish out of the carb. I agree with Kenny. In the gas is good. In the oil not so good. I am however a fan of Seafoam and use it in all my 2 and 4 stroke gas tanks and that ...

Depends on the hill, but if the engine is still reving and you are going that slow, then either the belt is gone or the clutch.

You forfeit the bike, because the towing and storage costs more than the bike is worth. Again the d*** cops can't take the bike anymore than they can take your car for speeding, until your day in court at least. If they arrest you and take you away, then they can tow. No detention and arrest, then ...

P.S. - me4get - Does Iowa enforce that 5 ft day glow flag rule? I don't think there's any other state that requires a flag! I know for a fact that Kentucky has the flag law, and they super-enforce it! :shock: I went down to Louisville a couple weeks ago to pick up a "87 SE50P that I won on E-b...

I have never seen a stock Spree go up a hill without appearing to lose power. The term "gutless" applies.

Anyone thought about just installing manual valve in place of the vacuum one? Ten times cheaper and even if the bag guy gets the key, the scooter won't run unless you turn the valve on. Then you don't have to worry about whether the carb needle and seat are sealing properly. :roll:

Since he was trying to drive around the building I would say he knew how tall it was, he just didn't know how WIDE it was. :lol: From what I understand the company that built the bank is being looked at for a law suit considering how easy it was to knock the drive through over. I'm sure the guy's t...
