Is this the kit you were speaking of?

Looks like lubrication issue. 1 year ago I was stuck in a hail/rain storm. Water was over the edge of where your feet go. I can assure you this has to be when it happened cause it has never ran right since that day. I though it was just the ignition coil (it was broken from corrosion) but looks like it was from the rain. And man was that a rain. My neck looked like I had about 20 hickies on it from the hail. Piston with lubrication failure. I use motul (spell check) 2 stroke oil. Is this a good oil?
Zombie, lets chat. It seems you can assist me quite abit. Yes, that is a picture of the scooter. I put that exhaust and the tires on 50 miles ago. Can you talk me through or send me a link for a BBK if it is within my budget. I am gone tonight, but I will check this when I get back.

What should I be looking for in the carb and the oil pump? I know the oil pump works as I have to put the 2stroke oil in when I fill up.

I can not seem to upload the piston/cylinder pics. If zombie you have an email, I can send them to you. The piston has major vertical chunks out of it. The cylinder wall does not though. What normally goes wrong in situations like this? It is a 2001 with 4500 miles on it. I think just a rebuild is the way I can afford to go. I want to get a BBK, but the other items that need to be changed would be out of a budget for now. I want to get ahold of that cylinder if I can for 20 bucks. What is the best way to go about this? Paypal? Thanks again.

I think the investment to put a BBK on is worth the money. However, I am not sure affording all the other items is within the budget. If I can go 45 with OEM, that is good enough for me. I will look into a kit, but I am not sure how to tune a carb very well, so I am stuck with having someone tune it for me. I will talk to my scooter guy back in ST. Louis as I am going down there in July. He tried talking me into one a year ago as I had to decide between new tires or a BBK. Went with tires, should of went with BBK at this point. I might be emailing about the cylinder. Is anyone on this forum in Nebraska?

I will use a rubber hammer to try to get it off. I hope I can get by with just a top end. I will keep you posted and your help is greatly appriciated.

At this time, I have removed the plug and the 4 bolts that hold down the head. I took that off. The combustion chamber looked like the inside of my smoker. Good for smokers, not for scooters. I cleaned that out with a towel. Now, I dont want to ruin the cylinder, but how much force is needed to get that off? Should the piston be up or down when I try to get it off? Can I use a rubber mallet? I looked down the exhaust hole and see lots of vertical scratches on the piston. I do not have any tools to measure. Will a kit OEM be okay to use? Is this something better left to a pro? The scooter scene in Nebraska stinks. No one works on them. How do you know if you can just replace rings and piston or when you have to get a new cylinder? When the cylinder comes off, I assume I would need to buy a new gasket. So on the list is an exhaust gasket, rings, piston, and cylinder gasket. Is this correct?

Okay, so In the last 50 miles, I have put on the rollers and a new belt. I can not remember if I put on slides. I think I can repair the compression problem. Would one of you be able to send me the links to the piston/ring combo I would need? Should I pull it off and send you a picture to ensure what I need? Would anyone have a link to a PDF of a step by step removal and install should I run into a snag?

Okay, so I re did the compression and I am at 99psi. Low for sure. But it should run. I put a new plug in, but it is getting wet within 1 minute of running. Got it going....rode a few minutes....and quit. Pulled the plug and it is wet. Re do it, ran it again and its not wet, but it wont run. I have cranked it and every 20 or so kicks and it makes a 'puff' noise out of the exhaust. Is this a sign of worn piston/seal?
To your question, it is a few times a week scooter. It used to be daily, but do to a relocation, it is 2 times a week. So I guess I would just like to get it to run. I don't want to have to buy a new carb and exhaust to accomidate a big bore kit. 45-50 mph is enough for me. Zombie, thank you for your assistance.

Went to the parts store and rented the compression tester. 60psi. 
Can anyone direct me on what to do next. Where to buy a kit to fix my issue. Maybe even a how to video or even a pdf of how to install.

I am at a point that I need assistance. I have recently purchased a cdi and a new ignition coil. Put them on, ran well, but then died. If I give it a touch of fuel, it will putter, but that is it. It seems like it is electrical as it will run a bit, and do more of an on/off running..if this makes sense. I have been messing with this scooter for a year since I moved. I have cleaned the carb, spark plug, air filter, cdi, and coil. What am I missing? On top of that, before I moved I put on new tires and exhaust because I dont have a scooter machanic here in Omaha, Nebraska. I wanna go back to STL!

Should I also replace the stator? The issues that I am having. The ignition coil wire was rusted and broke in half. Very LOW spark if any at all. While having a broken coil wire, would it affect the cdi at all? Meaning would it ruin or put resistance to the cdi and burn it out at all? Not sure. All I know is I need an igntion coil asap.

I am in need of a new cdi and ignition coil. I have a 2003 zx50 superfever. This is the first issue EVER. The ignition wire has rusted in half. I am not sure if I need to replace the CDI. However, I wanted to know where to get one as I am not sure if it is AC or DC. If anyone can assist me, I would really appriciate it.
