Re: Need throttle to start up bike
 

Actions:
-Turned the idle knob .75 turn clockwise. After the idle speed knob was adjusted when there is no throttle at all the bike moves about 5-6 MPH. (I don't have a tachometer so I am describing the RPM of my bike through how fast/MPH it moves without any throttle at all instead.)
-Put one-fifth of a can of Seafoam into the gas tank and rode bike for about 40 miles total since then

Results:
-Bike does not stall during stops anymore. Bike idle is louder. -- probably due to increased idle speed
-Bike seems to run a little bit smoother now -- due to Seafoam or placebo effect?

Lack of Results:
-In order to fire up the bike I still need to put it on full choke and throttle before I even press the starter button
-When it is on full choke and throttle and I press the starter button I still sometimes have to hold the starter button for the length of a several "tuh tuh tuhs" and when I get off the starter button the bike has to quietly make a few "jug jug jug jug" sounds while my bike is on full throttle & choke before it will sound off with a loud RRRRREEEEVVVV.

Any ideas on what else can be done to fix the latter? What is the problem? Or should I just bring the bike to a mechanic?

Re: Need throttle to start up bike
 

Sounds about right. Keep using the carb cleaner for the next 3 or 4 tankfuls & see if you get any further improvements. What do you mean when you say that idle speed is 5 or 6 MPH. Idle speed is measured in revs per minute (RPM)? Idle speed with the engine thoroughly warm, & the choke off, should be around 1400 to 1500 RPM. I wonder if the problem, all along, has been that you don't understand what "idle speed" means? Can you give us a run down as to what you understand by "idle speed" so we can see if there's been any misunderstanding?

BTW, 1400 to 1500 RPM means that the bike should sound more than 50% faster than the car, at idle. A car idles at around 860 RPM. :2tup:

Is it possible to set up a rev meter to a gz? Is it worth of hassle? anyone has it?

Re: Need throttle to start up bike
 

I shall digress off topic for a while to answer your question, alantf. Hopefully, there won't be more posts asking this because I want to focus on my problem.

I do know what idle speed means. But since I don't have a tachometer to check the RPMs I have been measuring and paying attention to my idle speed through a different medium/method. In addition to paying attention to the sound of the bike, I have also been paying attention to the MPH of the bike when I do not give it any throttle at all as a means of sensing what the RPM of the bike is.

Before I increased the RPMs/turned the idle speed up/idle knob clockwise .75 -----> the MPH my bike would travel without throttle was 3-4 MPH.
After I increased the RPMs/turned the idle speed up/idle knob closewise .75 ------> the MPH my bike would travel without throttle is now 5-6 MPH.

So yes, I understand idle speed is NOT the speed the bike travels when it is doing nothing. I'm just mentioning that the bike now moves faster without throttle so that other posters have a means to see where my bike is at in terms of RPM, since I don't have an exact RPM to tell them where my bike is at.

Did my explanation make sense at all?

Now back to talking about my main question, so I can get my bike working properly!

Re: Need throttle to start up bike
 

I thought that's what I had done! The bikes starting, so I said to run carb cleaner through for the next 3 or 4 tankfuls, & see what improvements you get. Next, forget all that nonsense of how fast the bike goes without throttle. LISTEN to the engine! Like I said, it's around 50% faster than your car idle. So - warm your bike up, make sure the choke's off, not in gear, and LISTEN to the engine. It's not rocket science! It should sound like a very fast idle - 50% faster than your car! If you can't grasp this concept, then I'd advise you to find someone who can LISTEN to your engine, and advise you. Notice that I keep highlighting LISTEN. That's the ONLY way you'll get it right without a tacho.
Phew, Hope you'll try this! :) :2tup:

Proper idle speed in a warmed up engine is 1300 rpm.

Re: Need throttle to start up bike
 

My handbook states 1200 to 1400, so 1300 is a good starting point to adjust it to what you're happy with. :)

Thanks alantf, Mrlmd1, and Gz Rider.

I will go with alantf's suggestion of using Seafoam over the period of several tanks of gas and avoid going to the service center if possible. It could be possible they did a shoddy job on cleaning the carb. When I first got my bike back after they had cleaned it I had to keep throttle on my bike at stops to keep it from stalling (this stopped eventually and the bike would run like normal). The full throttle/choke and stall@stops issue returned after I did not ride the bike for four days. Could four days cause so much problems?

I'm just afraid if I don't get a quick fix though, there might be one crappy day when I can't start it when I'm trying to get back home or something.

I have been calculating the gas mileage on my bike:

The tank was full at 917.45 miles and when I reached 1068.8 miles I filled it back up with 2.182 gallons.

1068.8 minus 917.45 then divided by 2.182 equals 69.36 MPG.

The tank was full at 1068.8 miles and when I reached 1226.45 miles I filled it back up with 2.47 gallons.

1226.45 minus 1068.8 then divided by 2.47 equals 63.826MPG.

My current mileage is at around 13xx and I still have not filled up the gas since I adjusted the idle so I'm curious if the idle speed change will effect anything. Is my current MPG normal?
