My quannon 150 will start then die.

[quannon guy]

Hi, I recently purchased a quannon 150 I've put only 400 kms on it so far....After it reached 100 km my quannon started having starting problems...it would start then after idling for 20 seconds it will die and won't start anymore...the engine will turn over but no ignition...I've tried playing with throttle to no avail, anyone know what would be causing this starting problem? Even my Remote control nitro cars and helicopters start much better then this quannon ...i'm so dissappointed.

Sup man...

Sort of a similar problem that I had....

Check the gas cap, seems that the factory doesn't vent them after shipping and expect that to be part of the PDI.  Pretty sure you just have to drill the hole, but don't take my word for it, my guys at the shop did it and I just caught the start of the procedure.

I also had an issue with the idle... long story short....

It was too low, so we turned it up so the engine wouldn't quit. Then we figured out the gas cap situation.  Left it a bit high, then turned it down to about 1600-1700 (adjustment when warm) but I kinda like it at 1800-1900.  It's something your mech should do or at least show you how to do on your own. 

Pretty sure if you do the venting on the gas cap, it will solve it.

oh yeah...the gas cap...

there's a little hole if you flip it over on the edge... apparently you have to punch a hole in it so that there is a flow of air into the tank so the gas gets through.

Hi badjoke, ya this is my second time in with the mechs, the first time they drilled to vent the gas cap it solved it for a week or so, then the problem arised again, it seems like when I leave the bike alone for a few days I have a hard time starting it... I do cover the bike with bike cover so no dust gets into the carb, anyways the second time I brought the bike into the mechs they said the carb is clean as a whistle, the problem was a kinked fuel line...fuel was just dripping into the bottom of the carb not getting enough fuel, so now I have it back in my garage it seems to be fine so far....i'll update again when things go wrong again.

[badjoke]

Ahh... that's a new one. 

Glad they found the problem, hope it goes well.

Ok so today I wanted to take the quannon to work, and it didn't want to start again, it started but then sputted when I tried to give it a little gas then died...then after it just didn't want to start anymore.

From what I recall everytime I take her to the highway the next day she doesn't seem to want to start....so after I got back from work I tried again this time b4 cranking her up I released the fuel cap waited 10 seconds put her back on and she ignited this time.? Now i'm wondering if it started because I let in air in the tank and let pressure out of the tank???

Another thing is also when the temperature is 25 degrees celsiius she won't start, when she did start the outside temp was at 20 degrees celsius?.

just wondering if the outside temp has something to do with my starting probs or was it because I opened the cap on the fuel tank that made it start?

Anyone with insight please respond....My mechanic thinks I don't know how to start a motorcycle and that I'm just bugging the crap out of him. 

[badjoke]

Weird...

FYI I'm no mechanic, so I don't know too much...

but if you're gas cap is vented then it should be letting air in.  If it works fine when you open the tank, maybe the vent isn't fully drilled through? (the gas tank isn't supposed to be sealed.  there's a vaccuum pump under the tank that supplies the gas..how it works I have no idea)

As for temp, I've run mine here with temps from 15C to 35C no problem.  Also rode on the highways and no problems the next day. 

Are you using the right gas? I think it should be 91 octane (at least it says so in the owners manual)
Fuel filter clogged?

Wish I knew more to help you with

When you're having problems with it starting or running - open the gas tank.  If you hear air rush in - then it had a vacuum and wasn't venting.  It should only take a splt second.

Riding on the highway uses fuel the fastest - so it would create a vacuum the fastest.  It sounds to me like the tank still isn't venting.

Air temperature and humidity do affect your carburation.  I've never been a fan of bike covers because most of them trap humidity.  Can you try leaving it uncovered one night?

The gas should be 91 RON, which is regular. 


P.S.  I wish it were getting as low as 20 Celcius here.  Night time lows are closer to 30, and the highs are 40 or above...

ok check this out, I finally made a video to show my mech why it starts sometime, I don't know why he didn't figure this out but I think the problem is occuring in the gas tank, lastnight I tried to fire it up and it was a no go...opened her up shook the cdi, wildly shook the gas tank, and saw a piece of thin tube sticking out underneath not sure what it does but here's the vid.

First try


Second try

[badjoke]

The tube is the overflow for the gas tank... if you over fill it, it goes down the hole (you can see it right between the hole where the gas goes in and the front of the tank...sort of in that painted collar. 

Have you been going to studio to have it checked?

[quannon guy]

Ya, i'll be going this Wed or Thursday depending on weather, i'm pretty sure its a clogged autocock or petcock.

[quannon guy]

I don't no why it would be clogged the bike is brand spankin new, only 450km on it.

[JustWantToRide]

First try - you gave it no gas and a short crank on the starter - then a lot of gas and a longer crank.  You might try cranking it for a full second and then slowly roll the throttle on to make sure you aren't flooding it.  I don't think the way you're starting it is the problem though.

Did you open the gas cap before trying to start it?  I'm suspicious that the tank still isn't venting - and it's easy to check by just opening the gas cap, close it, then try to start it.  Do it before you try cranking it.

[quannon guy]

Hi Justwanttoride, i've tried taking the cap off a couple of times, at first that trick worked a few times then it simply stopped working, the cap was also drilled by mech so its venting.

[badjoke]

I dunno...seems like they're doing everything and more for you.  Kinda lame you copy pasted and email....lol... pretty sure anyone who's a part of kymco might just maybe maybe know about this forum lol.
