Help..she Is Bogging Then Shutting Down.


Recommended Posts

Ok, just finished up putting in a new swingarm and axle. She was apart for about 2 weeks. Now its all back together and I go out to crank it. It takes MUCH longer to crank then it ever did before! It FINALLY cranked. full choke-half choke-no choke....Seemed running good.

Then once it started getting warmed up, it wanted to bog when going to 1/4-1/2 throttle!! Then it stopped. I roll out to the street slowly in 1st and at 1/4 gas, it shut off!! Kicked it and NOTHING....Would not crank back up. Took back to the garage. CHoked it and it cranked again, ran for a second then stopped.

 

I Really Dont think this is a jetting issue since it was running perfectly over a year with this setup. I Never took apart the carbs to clean them which I am thinking it might be something there.

My main concern with doing this is that I dont want to mess up the jetting or needles while doing this. I also dont know how to take them apart and where all the needles and screws are :(

 

Does this sound Like I need to clean the carbs out? If so do I need to take them all apart or just some of them...Can someone give some direction on this?

 

Thanks

Update: I took off the carbs and cleaned them out fully with carb cleaner. Took out the mains and cleaned them and the air screw and put it back the same # of turns. Also took apart the float assembly. Put it all back together and now it still dont start.

 

I think this time its not starting since there is no gas in there and there is left over carb cleaner. I am going to mix up some new gas in the am and put some starting fluid in the cylinders...We will see how it goes

I have the same exact problem with my bike this very second

and thanks to you I think I just figured out both of our problems.

I just installed my +4 swingarm a few days ago. Ran fine before that.

I don't know about you, but my brake line was long enough, but the

emergency brake cable was not. It's not hooked up on mine and if

that is the same case with yours I think we both need to do a search

on proper disabeling of the parking break. There must be a switch

somewhere that cuts the ignition or phases it back that is associated

with the emergency brake. Tell us what the deal is somebody.

04le, sorry man that is not the case with mine, as I dont have that installed any more. Was not instlalled when I bought it. Thanks for the hope though ;)

 

Also, now that I am looking at the carb diagram, I cleaned the mains and the air adj screw, but forgot to remove and clean out the PILOT JETS!!!!!!!

 

Would the pilot jet be responsible for this, or the main jets?

Well 99% good news: ITS RUNNING AGAIN :headbang:

It seems to be running pretty good now. Cranks on 1-2 kicks again.....

 

The 1% is because while sweeping the garage floor, I found a small crome spring which I hope is just for the air screw valve so I can easily reinstall it.

Is this what it is for? I dont remember removing it prolly becuase I blsated it with the carb cleaner and did not see it pop out.

:huh: We have no idea what kind of spring you found on your garage floor. Could be for anything. Good luck in finding that part out. :rolleyes:

sredish, the spring was a small 1 inch that went in one of the needle valves....There is not too many of these springs on the carb.

Question: the main air screw has a spring in it right? I think this is where it came from.

yeah, there should be a little spring in there.

 

what I hate is when I drop the clip from my needle, that is a big SOB to find. I did that twice when I was out at the dunes. I dropped it while working in my trailer and the floor is black and I could not find that damn thing for anything. If I wouldn't have found it, I wouldn't have been able to crash and break 3 ribs and collapse 2 lungs. Funny how that works. :rolleyes:
