Mostly tore down my Honda urban express (NU50) tonight and I'm still only getting around ~90psi for compression.I cleaned the exhaust and the head but there's a horrible brown slop coming out of the piston and crank. I did my best to clean the piston but it didn't make an impact on the compression.What's involved with rebuilding an express engine? Any way to bring the compress

New plug and there is spark both on the wire side and the plug side.I don't have a battery hooked up. Not sure how to test the cdi. Guess I'll look into it.It's so tempting to rip this thing apart and rebuild it. I'm so frustrated cause I can't get it to turn over.
No luck. I double confirmed spark (cut and wrapped the wire), something was wrong with the elbow.I can hear the engine cycle through 6-8 times when I try to kick start it but it still won't turn over.At this point I'm out of ideas other than stripping it down re-cleaning the carb and/or rebuilding the engine.Anyone have any other ideas I can try? Anyone close to Texas? ;)
Thanks! I'll give it a look. I didn't have the black and red looped up by the ignition.
I guess it doesn't help that I had to rip out the ignition because I didn't have a key. (Hot mess, I know).What wires need to be crossed in the ignition to act like the key is in the "on" position? Do I need a battery hooked up for the CDI?I thought I could kick start without any of this? I just want to make sure the engine will turn over, I can fix everything afterwards.
Picked up a 83 Urban Express the other day and I'm having trouble getting it started.• I fixed the starter gears so I'm able to move the kick start and I can see/hear the piston moving.• Compression is ok ~90PSI. I've read it's suppose to be higher but I'm not sure that's a deal breaker.• I haven't seen a spark but I can see it complete a circuit with a wire test
Not to hijack but I'm having a similar issue. Picked up this bike the other day and the wiring is shot.I've got 6 wires running out the side.1 & 2) These two black and red wires look like they were cut so I've attached them together.3) Green - assumed negative/ground4) Solid red - assumed positive5 & 6) Solid red with fused - looks attached with fuse on purpose.I'v refe
