Re: 1988 SB50 Resurrection

Belated Merry Christmas All. I got silly question how often do you all foul out plugs? Does it happen often? The reason i am asking is i took a 3 month break from the scooter and when i tried to start it it the other day and she would no fire up. The bike had run just fine (little hot on the top end...

Re: 1988 SB50 Resurrection

Thanks BONESV! I spent close to 45 minutes searching and never found that post. To admit i was doing a google search the first 30 minutes. I found the problem, the coupler was on backwards. The Coupler has a bigger internal rib on one side. This should be mounted on the manifold side vice the carb s...

Re: 1988 SB50 Resurrection

Ok some Updates: The bike is running super good. Slightly warm at WOT for extended periods of time (5 to 10 minutes with up-hill pulls included) at 370-400F Cylinder head temp. Have not seen any signs soft seizing and the plug reading looks good (dark tan to light brown in color). I changed out the ...

Re: 1988 SB50 Resurrection

Update: I had to get a new CT manifold, since i messed up the first one. Got the 30mm OKO carburetor installed. Needle jet e-clip in the middle position and she seems to run real good. The cylinder temps on low speed break in 15-20 MPH are at 220-260 F range. With a few up hill runs getting towards ...

Re: 1988 SB50 Resurrection

Ok, made some progress. I got the shock mount in and welded. The stock SA50 carb installed and the bike fired up. I wired the AF16 coil and starter harness spliced in to the SB50e harness. The interesting point is the wires matched color to the coil, except for the starter which is red/white on the ...

Re: 1988 SB50 Resurrection

The Flu took me out for almost 2 weeks, but back to work now. I got a few more items from the Philippines, but the fit and quality is less then expected. both the expansion pipe and PG copy did not fit very well. I will have to cut and re-weld the flanges so the rest of the pipe will align correctly...

Re: 1988 SB50 Resurrection

I have a few more questions, I just ordered a PG oil pump delete and a few other small items from Scooterswapshop. This should get me up and running for the mean time. The question i had was about the electric choke on the stock AF-18E carburetor. The one i received had the wires cut off at the sole...

Re: 1988 SB50 Resurrection

Ok all, made a bit of progress. I have added a few pictures to the Bucket. Looks like i will have to modify the motor mount a bit. First I have to notch the bottom and angle cut the rear of the mount. This will facilitate the continued the use of the stock kick stand and provide the clearance for th...
