Honda Spree and Elite 50 Forums

1987 Honda Elite. I am at my wits end with this thing. I have a complete moped for spare parts and have tried the following. Changed, carb, bystarter, petcock (cleaned), new gas, head gasket, decked head. It will start up with a dry plug and idle up for about 2 or 3 seconds then will bogg out and die whether I give it throttle or not. I have tried sucking on the vaccum side of the petcock with my mouth and no difference. The bystarter checks out fine. Cleaned carb and checked float clearance all okay. After it dies I will pull the plug and its wet with fuel. Originally would not start due to beehive in the exhaust. With that clean it will fire and die. WHAT AM I MISSING?

plug chop? almost sounds like its lean and the bystarter richens it up for a while.

Whats plug chop? So should I bypass the bystarter to see if its lean then?

Run it wide open throttle for 1 minute and while keeping it at wide open kill the motor keep on the throttle till the engine stops completely. Then remove the spark plug and look at the ceramic insulator inside it, what color is the insulator? coco brown is perfect and anything up until black is ok if its black and wet its too rich and if its a really light brown or white then its lean.

I can't get it to run that long. About three seconds and thats it whether I have it wide open or not.

well what does the plug look like after running as long as it can?

Looks coco brown like you described but very wet as well.

Did youcheck your reed valve assy?

I went and bought a new reed valve set from the dealership. I noticed the old reeds were bad but that still didn't fix it.

Are you sure your idle jet is clear?Mine would start and idle for a few minutes and then once warm would die.I thought the idle jet was clean,but it was not.I found a very fine wire(small quitar string) and then one even finer and found the jet to be blocked.Once clean it idled great. Now I have the bogging out under load problem.May also buy new reeds.

lol all i see if plug chop, theres way more to trouble shooting a moped then that. like for instance,using your hand over a carb can tell you tons of things bout your jetting. Anways..your problems sounds like stuck open petcock , disconnect the fuel line and see if its flowing gas, it shouldn't be. Gas only goes thru when you motor have vacuum. if its not pouring out, then i would suck on the vacuum line to make sure once its flowing, it doesn't get stuck open. I assume yo overhauled and cleaned your carb.
hope this help!

Got it fixed ended up being a clogged idle jet even after I cleaned it with a piece of wire. It has great power but will not go above like 15-20 mph. It likes its topped out way before it should be. My book says to check and see if the drive belt is slipping. It doesn't seem to be because i try to hold back on it and give it fuel and it was to go. Any ideas? Thanks for the help thus far.

What about the clutch pads?Could they be slipping under load?You may not be able to hold it by hand but it may slip under load.Where is your main neeedle jet clip positioned?

Factory position...how would i check the clutches? I don't think anything is slipping because it will pull right up a steep hill no problem. Plus I don't smell the clutches anyways.

Did you check for proper compression?You sure you got all the bee hives out?Someone suggested I try running mine without the muffler to see if that helps, but I have not got around to it yet.If it pulls well then it probably is not the clutch.Mine pulls well too until it warms up.If reed valves do not cure it it may be the CDI?????
