View Full Version : 110 Running issues, Ideas?
Well, this gem i picked up from under the tree line http://www.3wheelerworld.com/showthread.php?105442-Got-a-New-Project-83-110-pics&highlight=
Has been giving me a few issues, It got a good service new tires, ect..., Now it dose not seem to want to run past half throttle without the choke on, The carb and fuel system are clean top to bottom, no water,crud ect... The intake has been Trued' and sealed good, valves adjusted, timing is bang on, new plug. i haven't done a compression test as i don't have a small enough adapter, but it dose smoke pretty good, the exhaust is not plugged. I'm starting to lean towards a Venting problem, bad valves/ low compression....Any idea's would be appreciated...have never run into this before... :lol::beer

Well, it seems to me if it doesn't want to run past half throttle without the choke being on, then you have some type of fuel problem. It could be the vent in the gas cap no venting. It could be the screen behind the fuel shut off valve clogged. It could be rust in the tank. It could be something messed up in the carb, but either way, a fuel problem.

I thought so at first to- but all of the above have been checked...and re-checked, Other than some sort of casting flaw of some sort in the carb...but it seems all the passage's do what there supposed to.

The breather system on the 110s are very picky . make sure the boot between the carb and airbox have no leaks and a good filter and the air box lid is tight with no leaks . if your having to choke it the air fuel mix is off . basically it needs a good amount of back pressure on the intake side for the motor to perform correct and if your lacking in back pressure it will only want to run with the choke half open . Hope this helps

Hmmm, I will double check that tomorrow, The filter should be ok, i cleaned and gave it a very light oil... i did notice the seal to the air-box was sketchy...but on .Them old rubber tubes seem to shrink,harden up n shorten up with age...

I'm assuming you changed out the filter and hoses that were pictured on the trike when you got it? Did you rebuild the carb with new jets? Is the mixture screw adjusted properly?

Hose's?...the filter was salvageable, the jets where cleaned, the screw is right, I forgot to mention...it runs the same with or without the air-box, I Highly doubt the carb has been messed with, but i suppose the jets could have been drilled, I will check out some more Tomorrow

Well obviously something isn't right! LOL Sometimes you have to check these things more than you have checked. Been there,done that. But I don't think it would be an electrical problem if it runs better with the choke on, I mean that just doesn't make sense. It's a problem in the fuel system. What exactly, it could be anything. If it changed from being really hot to really cold where you live or it got really rainy or humid, it could change the air/fuel ratio. If you just got some fresh gas, it could be crappy. If I've had leaks on the intake, my trike usually won't run at all. Try running with the gas cap off the tank and see what it does. You could have a collapsed fuel line. It could be a ton of things. You are just going to have to assume it's all wrong and you have to start over on the fuel system. Check the easiest first. Make sure gas is running out of the fuel line and the whole bit. There is something you are missing. If you just rebuilt your carb, did you make sure you replaced the jets with the same size jets? Did you slide a drill bit in your jets to make sure there was no obstructions and that the jets were the same size as the old ones. I've seen new rebuild kits come with crappy jets. Have you checked your throttle cable to make sure your side is going all the way up under full throttle. Is there too much play in the throttle cable. Is the throttle cable hanging up. Does the throttle cable need lubed. Did you leave out a o-ring or has one of your o-rings cracked. Go over it all again, piece by piece.
I hear ya veal, This isnt my first walk in the park, i have worked on a lot of machines ( used to to it daily) Been to school somewhat for this, and this thing is really starting to Piss me off....hahaha, I haven't replaced the jets, but as i remember, they where stock size's or close to it, unless they have been drilled...the thing that gets me is i had it running good on 3 flat tires....go figure....But thank You guys for the insight..and help....never hurts! :beer

I'm 100% the float in your carb needs adjusting, when you have to use the choke like you said,,it is starving for gas. the bowl on the carb does not have enough gas in it, adjust the float.
The float is non-adjustable by standard means, i could bend the pin, but its pretty close, and iv seen A LOT worse run a lot better.... Think it might be time for some rip and tear action....haha...

How is your float needle? Maybe that's sticking? Which notch is the slide needle set at? By hoses above, I meant lines. As cheap as those are, I would replace them. Same with the filter. Is there maybe a little piece of rust plugging the feed hole coming out of the tank? What about the petcock? I see that was missing when you got the bike. Is there something going on with that maybe that's starving the carb?
The needle is good and clean (viton tip) The slide needle has been up down and round, the lines have been replaced, This one has no filter in the tank for the lines, The Whole petcock/bowl assembly is new from honda, (the only way you can get the petcock) The passages all seem to be clear and working right, i might drill the rivets out of the petcock and take a look to see if it is right.

I wasn't trying to dog you out, I just know that a couple of times when I thought I'd checked everything, well, I didn't! LOL And the worst thing is, it's usually something that is simple that one misses. Have you tried running the trike without the gas cap. Maybe a piece of tin foil or saran wrap over the tan inlet with a couple small holes punched in it to make sure the tank isn't vacuum locked? I had that happen once. The vent hole on the cap was rusty and the tank was vacuum locking. That was a real pain in the butt to figure out.

I wouldn't drill out the rivets if it's new. It should be good if it's from Honda. About all you can do is check everything in the carb again and try Vealmonkey's advice about the cap.
Sorry guys, im not trying to come of as a trailpro But i did run it without the tank cap (one of my first thoughts, had it happen before) should have made it a bit more clear i guess, One of the reasons i'm looking for idea's....i am gona mess with it a bit more tommrow...it dose this with or without load on it, Might just yank the motor out n take a peak, could use a good top end anyways.:beer
Well Guys, thanks for all the Suggestions, But i Got back around to messing with it the last few days (took it for a ride)...Threw a carb kit in ect....Tore it down today...Bad intake valve...Looks like it and the piston got a little too close and personal at one point in time...Chiped in a couple spots...:beer
