By the way, I ordered an electric scooter from Safer Wholesale. 800 watts will make gas powered transport irrelevant.

Ok. I'm back on this. Spending this evening getting the procedure down correct. I plan on completing this tomorrow. Easier said than done. I'm sure everyone has told me that over and over. I spent about 2 weeks watching and reading every BBK install video I could. When I found Brent's video Insat down and wrote it down step by step. I put little check boxes next to each step and sub step this way I knew where I was and what I had done so far. Take your time. Who gives a rats ass if it takes you all day or 3 hours. Do it once, do it right. After you get it running let it idle slightly high for about 20 minutes. Let it cool down completely and check the valve lash again. It will probably need to be done again. And possibly one more time before it holds and everything settles in. Run It on the fat side for some miles than start tuning it. Than enjoy.

By the way, I ordered an electric scooter from Safer Wholesale. 800 watts will make gas powered transport irrelevant. Except for the very limited range due to the battery limitation. EV's are just not there yet...they are indeed getting better but still have a long way to go in my opinion. Good luck with it though. Bill

My understanding of this is there. I plan on working on it after work this week. It would be a good idea to get the ring expander. I was dealing with the issue of rebuilding it as 50cc or 72cc. I am going with 72cc. These scooters are underpowered anyway. The xr50 engine stock 49cc has about the same horsepower as one of these scooter engines modified to 72cc. The limitations of electric can be mitigated by installing extra batteries. Winter is going to be very interesting. Sorry for some of my more irritable posts. Irritability is a consequence of being married to an abusive woman. Not married to the abusive woman anymore. It was that scooter that allowed me to walk out on her. Thank god for scooters, hey?.

Adding more batteries increases weight which slows the vehicle and also makes the motors work harder. Until there is a significant change in battery design and capacity and towns and cities build enough charging stations to make EV use viable EV's will be limited. Having ride in a Tesla P85D yes the torque is mind blowing but the cost and range make it a rather impractical vehicle for most of us.
Although a ring expander is a nice tool to have it really isn't needed to complete the install. Lots of assembly lube, proper ring gap and patience are all that's needed. I had one from building the motor in my Mustang so I used it. But Inwouldnt have gone out and bought one if I hadn't had one.

Ok. I am getting this. Got the piston set up right with the rings sans ring expander. I am going to go for it tonight before the next rain storm due here on Friday.

I am back on it. I may have to abort. You need a ring compressor to get the piston in the head. I am not having any luck doing it without one.

Done many many top ends without ever using a ring expander or compressor... maybe there is some other issue? Checked ring gap?

You do not need a ring compressor to do the job if you are inserting the piston from the bottom of the jug (That's the way it should be installed) the bottom of the sleeve has a chamfer. If you take your hand and gently compress the rings while wiggling the piston into place it's not difficult at all. Make sure you line the cylinder wall with a coat of oil or assembly lube as well as coating the piston skirt and rings with either of the above. Another option is to insert the piston/ring assembly into the bottom of the cylinder while it's on a bench. That makes the piston installation easier. And make sure you have the piston positioned so that the intake relief in the piston is oriented correctly.

I am going to have to abort. You definitely need a ring compressor to do this right.

you can see the chamfer in the image above. This AIDS in compressing the rings allowing the piston to slide into the bore.
