Alsenor, man what a bummer. Maybe with some luck it won't be that bad. I'm sure you'll keep us posted. I'll check the socket size for my spark plug and let you know what it is. Gary S. I certainly will. Now I am waiting anxiously for your socket number! ;D

Alsenor My NGK plug DPR7EA-9 uses an 18mm. socket. I remember it being a little hard to find one.

I was afraid of that too. The only ray of hope I still have is the fact that the engine idled smoothly after the power loss, before I switched it off. Should a scorched piston idle smoothly? Yes. Low compression won't keep an engine from idling. It will keep it from starting. When my valve spring broke I still had the inner valve spring left. The scooter ran fine at 40 mph and idled perfectly. It just wouldn't run over 45 and made a racket as the valve floated if I tried to go faster. It started fine too.

I've taken an interest in this cause i may get a new scoot soon, i hope. Sounds like a hard break in is alot of varying your speed. Never just running along a one speed More on and off throttle. Don't hold it at any one speed for to long. Sounds like you need a long road with very little traffic so you can hit 50 20 40 30 and other mph back and forth. Does this sound right. Your right. You need a quiet road. This was what I did: "One night after work, a rider and his new scoot at one, working on a single goal, to get perfection needs wisdom and patience..." Sorry I got carried away, wouldn't bore you more with rubbish like that. ;D Changed oil then I took mine with 15km on the clock to a quiet road. From stand still accelerated to 20kph with WOT, then as soon as it hits that speed shut throttle totally down and let engine brake the scoot to stand still, let idle for about 30 s cool down time, repeated this 3 times. On air cooled scoots I would shut it down. Then repeat to 40kph WOT, close throttle totally down and let engine brake scoot to standstill with cool down time after, repeat this 3 times. After that when I increased the speed I did it by 20kph and repeated procedure 3 times with cool down time between each run. I took it all the way to 120kph that way. The total distance of this was probably close to 100kms. Changed oil after that. After that I always accelerated WOT to about 20kph (speedo) above speed limit, closed throttle to engine brake back to speed limit and limited constant speed running. At traffic lights I tried to use as much engine braking to bring my speed down. As a final I took it to the hills, accelerated WOT up to the top until I hit speed limit, engine brake to get speed down to make U turn, then WOT to 100kph speed limit and the closed throttle down steep hill to get as much engine braking (suction on rings) to clear them real good. I changed oil often in the first 1000 kms too. Also changed the gear oil a few times. From then I ride it as I feel that day. Mostly at a moderate pace ;D ;D ;D

So much for that...this was the last hope I was clinging to, and your revelation just shot that down as well. Sounds like you got all the symptoms covered.

Hey, Alsenor,
Just read what happened with your bike, it about made me sick. I hope it's not as serious as it sounds. Keep us informed.

If you have a C plug its a 5/8" socket.The D plugs need a 18mm socket.I doubt you have a D plug.Typical scoot plug is the cr7sa ngk brand.

But I'll tell you what Al, run your compression test and see what you get. After that take it back to the dealer and have him work on it. I understand abuse, others might disagree with me, but this is 2009. Engines should have some leeway, especially water cooled ones. If you rode for an hour, uphill, WFO, in 100 degree heat that would be one thing. but I don't think you should have burned your rings into the lands this easily unless there was no oil in it. Or the coolant system had an air bubble and no water was flowing. Maybe your warranty will cover it, you have nothing to lose by pushing the issue.

My personal problem seems to steer this thread away from the intended subject. Since I am the one who started this thread I feel responsible for moving my problem to a new thread. I really should have named it "70-year old idiot cooks new motor", but I called it "Al's problem": scootdawg.proboards.com/index.cgi?action=display&board=talk&thread=25441All you nice people trying to help please find me there!
