Re: 1988 SB50 sputters high speed

I saw there is a 48mm BBK on ebay in Nevada. Is this from the same guy?

Re: 1988 SB50 sputters high speed

I sent a message to tazland. Is there anywhere else I can get a BBK? Where can I get parts if I just decide to bore it? I'm going to need at least new gaskets, piston rings and piston.

Re: 1988 SB50 sputters high speed

Well the scores in the cylinder do catch my fingernail. So the best thing to do is get a BBK then right? So where can I get one for a reasonable price? What choices do I have to choose from?

Re: 1988 SB50 sputters high speed

So I got the cylinder off today. I checked to see if it's warped and it's not. I took a few pics of the bore. It's slightly scored on the exhaust port side as you will see in the pic. The piston rings weren't stuck to the piston. So where do you think I should go from here? I think a light hone, new ...

Re: 1988 SB50 sputters high speed

I am on a trip right now. I won't be home to take a pic til Thursday. I hope I can just get by with honing,new gaskets and piston rings. So what would be a good BBK for my scooter if I decide to get one? What else would I need to change if I do it? Thank you for the help!

Re: 1988 SB50 sputters high speed

Once I get the cylinder off I will determine what I will do next. If I decide to get a BBK where should I get one? Where can I get parts if I just need gaskets and piston rings?

Re: 1988 SB50 sputters high speed

So I took off the cylinder head. The cylinder head is not warped. I can see into the cylinder and it's scored along the exhaust side of the wall. It's not too bad and should just need to be slightly honed. I didn't have enough time to get the cylinder broken loose and removed. I am assuming I will ...

Re: 1988 SB50 sputters high speed

I did the compression test with WOT and 75psi was what I got. So that is bad news for me. I will be tearing it down this morning. I will post what I find. Where is the best place to get parts?

Re: 1988 SB50 sputters high speed

I performed the compression test today. The result was 75 psi which is well below what it should be. So the next step is to inspect the cylinder, piston and rings? I was pretty certain that this was the next step. So where is the best place for parts? I didn't have time to tear it down already.

Re: 1988 SB50 sputters high speed

Well I will be home tomorrow morning. I plan on working on it first thing. I just hope I don't need too much in the way of parts. I'm prepared to do whatever it takes to get this scooter in good health. So what would be your theory on what all is damaged?

Re: 1988 SB50 sputters high speed

Do you know where a good place to get parts is when the time comes? I am assuming I will need to buy some just don't know what yet. So anything below 142 psi I can consider there is something damaged?
