Yup I use my fingers as well when i slide my piston in the hole ... Wait a minute that didn't sound right .....mmm?

Rained last night so this is the night to get it done. I did find the taper in the cylinder. What a smart technique that avoids the use of a ring compressor.

Your fingers. Seriously, unless you got the wrong rings or something wacky is going on here you should be able to fully compress the rings easily with your fingers. Check out a couple YouTube videos. That might help you see how it goes.

Another technique for tight jobs are zip ties. Squeeze the rings, slide the cylinder over the piston and it pushes the zip tie down and then just cut it off.

Rained last night so this is the night to get it done. I did find the taper in the cylinder. What a smart technique that avoids the use of a ring compressor. It works quite well though! It's not going to slide in like butter. It will take a little bit of force to put the cylinder down over the piston, but not much. Also make absolutely sure you do have all the rings in the grooves properly on the piston. If one is not seated properly, then it will catch and bend and you'll be finding yourself a new set of rings. Also, like others have suggested, check your ring gap. Maybe 1 or more of your rings do not have any gap so they won't compress around the piston. All you have to do is place the ring inside the cylinder bore evenly and measure the gap with a feeler gauge. You should be doing this first anyways (Not implying you haven't, just want to make sure you're checking them). Make sure you also stagger the ring gaps from each other so they are not overlapping. One more thing: Don't try to put them in dry. Coat the inside cylinder walls with some motor oil, and do the same with the outside of the piston and the rings. This will help it slide right in. You can wipe up the excess oil in the cylinder, or just let it burn off when you first start the scooter..

I just broke the top ring. Now if people were a little more accurate on here and can lose the bullshit, I would've known to get a ring expander. I can't wait for another ring to come in so we are back to rebuilding this as 50cc. This is very time consuming and takes many special tools. Telling someone something other than that is just simply a lie that is going to undermine them. God, in the last 30 years bullshit has gotten worse.

It can be done, and if you need help you know I am local. Get another set of eyes on it, people have offered to help. Calling bullshit on people that have actually done what you are trying to do sucessfully isnt going help you do it.

I'm in the middle of doing this big bore kit. I am definitely better off leaving the 50cc head on and getting my money's worth of that cylinder until it wears out. Can't get the piston back in the head. This is not as easy as everyone says. You need special tools. Are the rings not on the piston IN YOUR VERY FIRST POST? Had you done research you would know they are brittle and to be careful. I've broken them and know to be careful.
For you to come on here and call us liars and tell us that we are full of shit... You're out of line.
I guess that's all I have to say, but I would definitely like to say more.

Why did someone say on here that they can rebuild it in 30 minutes?. We don't need that kind bs on here. The only reference I'm making here is society is a lot more full of it now then say 30 years ago.

With all of the disgusting politicians lieing through their teeth, we don't need that on here. If I had a difficult rebuild, I am going to say that, not that I accomplished it in 30 minutes.

If the motor is away from the bike, then that's an acceptable time. Motor attached to the bike might be 45 minutes. This is of course to someone who has this done this a few times. They are simple little motors.

Spaz12 I wasn't looking to call anyone a liar. What I am making reference to is my frustration with the current society we live in. In the last 30 years things have rapidly gone downhill with people. We have the rise of disgusting people. People who habitually lie. People who are hollow and petty. I can't stand people like that. They are disgusting. I had a guy recently unfriend (not facebook, I'm not on there) me because I don't drive the same brand of motorcycle he does. How hollow and petty. The world as we know it now I call it fucked-up society because that accurately describes what we are now dealing with. Why can't people be honest and help their fellow man......

I wish I lived closer I'd come give you a hand. I've learned a lot about scooter engines here and I've been frustrated more than I care to recall. I just put an engine together from raw cases this weekend. I'm now doing my least favorite part, carb tuning. I suck at it but I'm learning. Be patient, watch videos, and listen to Spaz. He know his shit.

Maybe it would be easier for you to remove the motor. All that is required is to unplug the wires to the stator, spark plug boot, the engine mount bolt and shock bolt. Once removed it is a lot better and easier to work on. Not nearly as frustrating either. You'll probably need help to preposition the motor back into the bike though. Yes, it would be a lot less frustration for you if you removed that motor.
