Re: 1989 SA50 will idle but not rev after bearing replacemen

I tried to compose a single comment, but it kept getting rejected by the spam filter.

What is "the facebook"? ;)

Re: 1989 SA50 will idle but not rev after bearing replacemen

<sigh> I'm an idiot. I know.

I replaced the spark plug on a whim, and it runs fine now. I thought I had excellent spark, but no....

Hopefully someone else will be able to gain something and troubleshoot their scoot based on this thread.

Re: 1989 SA50 will idle but not rev after bearing replacemen

Alright, lets go through the checklist: Spark a. Pulled the plug and cranked the engine. Saw some sparking. See video. http://youtu.be/BoiKh_nkSUg b. See close up of the spark plug. Looks like it is a little rich? IMG_0803.JPG Compression a. Put the compression tester on there and cranked with WOT. ...

Re: spree runs kind of...

So Wheelman, the theory here is that at idle, when there is high vacuum and low fuel demand, the carb gets enough gas. But when the throttle is open, either the vacuum is not strong enough to open the gas value in the tank, or if the value does open, the strainer in the tank is clogged. Either way, ...

Re: 1989 SA50 will idle but not rev after bearing replacemen

No idea what to do. It will start and run, rev up and then die. I dumped some oil in through the plug hole and it started and reved high until the oil was burned out. Pulled the vacuum line to the fuel tank and the engine speed up, but it died after and wouldn't run right. It reved up before I repla...

Re: 1989 SA50 will idle but not rev after bearing replacemen

Here's what I've done: Carb: I've cleaned it three times and everything seems in order. Spark: pulled the plug and cranked it to see lots and lots of sparking. Reed: reed seemed fine when I put it back together. I pull the reed again, and it still seems fine. Compression: i put a tester on it to ver...

Re: 1989 SA50 will idle but not rev after bearing replacemen

The other balls were running freely between the two races. Crank has play in it. Replaced only the bearing and reused everything else. Crank spun smoothly after the replacement. Now, she won't rev up. Starting can be a little difficult, but once idling, it will sit and run forever. Open the throttle...

Re: 1989 SA50 will idle but not rev after bearing replacemen

Pulled out the engine and tore it down. Used the kitchen table, which is one of the perks of not having a gf. ;) Main bearing was shot; the cage in the bearing was only holding 2 of the 7 balls in place.

1989 SA50 will idle but not rev after bearing replacement.

Well, as the title says, my scoot won't rev. History: Found scooter in a garage. Hadn't been run in 20 years. Cleaned out the carb, put a bolt in place of the screwdriver that was holding the front suspension together. Put about 3,000 miles on it over the next two years. Even ran through the gas tha...

Re: 1984 Honda Aero 50 - headlight bulb replacement

My low beam on the headlight for my '89 elite went out. I'm current running with the high beam on. Seattle PD doesn't seem to care much about legal equipment on vehicles, what with all the gun violence this year... :confused: Anyhow, I do want to replace the headlight to get back a low beam. Looks l...

Re: speedo cable

So, do all the Honda Scooter cables have the same P/N that starts with 44830? I bought a speedo cable off of Ebay that was advertized to fit an '88 LX SA50, but when I got the cable it was just under 32" long. It is too short; it's part number is 44830-GW0-000. The original cable was about 35-3...

1988 Elite LX

Found an Elite LX at a former crackhouse.... Hadn't moved for 15 years. But that is a different story..... I'm all about efficiency. Well, I'd like some top end. And a little bit off the line. No seriously, I'm about efficiency (and top end). The scoot is bone stock. I found it with 1071 miles on th...
