I'm about ready to take this to a Honda Dealer!!

Post by dr.ona »

I'm sooo frustrated right now!
I did an engine swap from one 1986 Spree to another 1986 Spree. The engine I swapped out was running great...I put it into another Spree...hooked everything up and the engine won't go faster than 15 mph. It starts fine...revs up good while sitting on the kick stand...but as soon as I get on it and go, it will not go more than 15 mph. Here's what I've done...
Rebuilt carb TWICE.
Cleaned the gas tank/filter/lines.
Cleaned petcock.
New oil and cleaned filter/lines
Looked at reeds...looks great..no gaps...installed new gaskets
Tried running it with both bystarters..no difference.
I did a compression check twice...both at 110 psi.
Tried a differont sparkplug....same results.
Looked at drive belt...good.
Cooked the muffler.
Pulled head and cleaned piston off....it was very clean.
Loosened back brake thinking MAYBE it hanging up...nothing still.
The gas I'm using is good cause I use it alot on stuff.
I really don't want to take this to a Honda dealer and get charged $50 buck an hour...I know it'll cost a lot of money to fix whatever is wrong but I just don't know what else to do. I've got the normal amount of smoke coming out of tail pipe.
I've double checked my work and everything is back together right. The only thing that looked MAYBE wrong is the O ring between the carb and the intake manifold adapter had a couple small cracks...but it was not broke in two.
Any other ideas?
Here's the results from a plugchop at going 15mph...
The other thing I've noticed is that the sparkplug is always oily...

Make sure the 2 intake holes on the airbox arent clogged up. Also make sue your needle is set in a middle position.
I am not a mechanic, nor do I play one on TV. Actually my advice is probably worth slightly less than what you pay to view it.

Airbox isclean along with a new filter...I'll check the needle position this weekend...
Does the sparkplug tell you anything?
I thought maybe the throttle cable was bend or stuck but it has full range.

Try moving the spark plug wire/coil over from the working bike to the hosed one. I had a similar issue once and it was the coil.

Wrong. It depends on the dealer.

My local dealer had 3 sprees they were working on last time i was in there.
The only problem is most of the guys don't know what they are talking about when it comes to 2 strokes.
"Its not what you ride, its that you ride"
1996--------Honda Elite S-
1991--------Tomos Targa-
And a Bunch of other bikes.

That's true, too. Honda will tell you the thing is totally hosed and that you needs to buys a new something from them. This forum is pretty much your only hope. Don't worry, we'll help you figure it out!

When you took off the head did you put a new cylinder head gasket on or reuse the old one? That may be your problem. It also may be as simple as checking your air screw setting on the carb. Your plug looks like its running too rich. Set the screw to the recommended setting for your year of bike. Are you using the recommended 2 stroke injector oil?

My Honda dealer will work on it...they've been great for advice over the phone but I'm afraid it'll cost me more than what the Sprees worth.
I did use Honda 2 stroke motor oil.
I have the air mixture screw 1 1/2 turns out from stop.
Used the old head gasket...the aluminum one...in perfect condition.

This motor ran great before I switched it over to the other Spree. So far I've done so much investigating/work to it I don't know where I should start again.

If this was a car, I would think it was...
a) fouled plug(s)
b) plugged fuel filter
c) Running on 2 cylinders

Thanks for the help so far though...

I don't know how accurate of a plugchop I can do at 15 mph but the photo is what I got.

Here's the latest...
Change the coil out....same results.
Checked the throttle valve...it was already in the middle slot.
Now...
I decided to exchange the carbs...
Fired right up...sounded better...reved up faster while on stand.
Took it for a spin...much faster!! Had it up to 27 mph.
I had it full throttle as I was approaching a small hill...halfway up the hill it acted like it was going to die then it hesitated...I let off on throttle...felt good again....gave it full throttle...running great...then the dying/hesitiation thing again while on flat surface.
I'm feeling much better believe it or not...
Any ideas on the new situation?
Thanks!
Robert

Sounds like a carb problem all along. Clean this new carb again thoroughly. See if the air screw setting is set the same as the old one by counting the turns it takes to close it and then turn the same amount of turns back out. Make sure the connection is tight between intake and the carb. Also make sure you have a tight connection from plug wire boot unto your spark plug.
