There's no coolant to burn so I concur with Stevo.


As for the "pop" and no-crank, :dunno_black:

Perhaps check your float levels?  I'm imagining fuel overflow into the cylinders causing a backfire for the pop but the no-crank is a bit of a mystery to me.
Maybe triple check your fuel system, since you were in there recently.

I just checked the float levels again and I think I measured them wrong the first time. In the manual it says to measure it when the float arm just comes into contact with the needle valve, but from doing some research people say to measure it when the float arm seats the needle valve, but doesn't put tension on the spring. So I guess my float heights were too high and the engine flooded. :icon_eek:

That probably explains why it's smoking a lot on cold starts, too much unburnt fuel in the exhaust perhaps. The spark plugs were pretty brown and a little wet so it was definitely running rich. I don't think it's burning oil because it only started smoking like that after I messed with the floats. I will do another cold start later today and see if it smokes some more

well you may be stalling it by braking without first pulling the clutch (I know, dumb question, but you never know). "jerking" and then "just stops" when you come to a stop sounds a whole lot like stopping in gear without pulling the clutch lever.

If you are coming to a stop with the clutch pulled all the way to the bar and it "jerks" and "stalls" then I can't figure what would cause it to "jerk"... I mean, it should basically coast smoothly. The engine may run rough and stall, which probably means the pilot jet is clogged in each of the carbs. Remember, you are going to have to go through these carbs and clean them thoroughly, probably replace those tiny pilot jets because there's no way to know they are not clogged unless you have a set of precision drills, and replace all of the o-rings, especially the pilot needle o-ring. Until you do that, bet on it running weird.

FWIW my dad has a '07 or so Honda Shadow 750DC and he bought it with about 2500 miles on it, had the carbs "professionally" cleaned when he got it because it ran poorly about 4 years ago. It did fine until just recently when we noticed it was leaking fuel from the carbs somewhere a few weeks ago. Now it has about 8K and we had to pull the carbs and completely go through them. This time I replaced all o-rings, gaskets, float needle valves, and thoroughly cleaned and re-adjusted things. 5K miles with ethanol gas will do a serious number on motorcycle carburetors. Runs like a champ now but it is a constant effort with carburetors.

"White Smoke" is Condensation, only worry if it "pops" when warm  :cheers:

General GS500 Discussion / GS500f white smoke on startup
« Last post by mrdrprof on March 18, 2019, 11:15:32 PM »
Hi, my 06 GS500f smokes a bit on cold starts and it goes away when the engine is hot. It doesn't look blue at all and doesn't smell oily, but it sits around for a little before dissipating. Also, I went to start it today after almost a week of sitting, and it cranked like normal and went to start and heard a "pop" sound. Then, the bike wouldn't crank. The lights would go dim or out but it wouldn't crank. After letting it sit for about 30 seconds or so, it cranked again and started right up. Could this mean anything? I recently adjusted the floats and added a 20 pilot jet if that helps at all. I have the stock exhaust and airbox/filter.

Starting a GS (cold or sitting more than an hour):

1. put choke on FULL (all the way back)
2. start with NO THROTTLE
3. bike will start and perhaps with a blip of throttle after it starts should idle up to "fast warm up" at about 5K RPM
4. after a few seconds fast idle reduce choke to 1/2, should idle at 1500ish RPM and go ride
5. after a mile or two on the road you can probably turn the choke off and run without choke, should idle at 1100 rpm or so


If the bike doesn't want to run when stone cold without choke, that's normal. it would be worrisome if it does run stone cold with no choke.

"bog" usually means lean, which usually means you open the throttle and more air comes in but not enough fuel to match. If this GS is doing that, like refuses to rev when opening the throttle, then odds are there's a major vacuum leak causing the slide not to come up, or sticking float needles so the carbs run dry of fuel, or one of a hundred other things. Again, you get an old bike like this, expect to immediately have to go through the carbs. I have a write-up on how to do this on my blog.

Thanks for the tips! I was just able to ride around locally for about 15-20 mins just to test it out. This is only my second time riding a bike, but when taking off it seems fairly smooth, I follow all the steps for starting the ride (put in first gear, slowly release clutch, put on a little bit of throttle). Once I'm rolling it does ok, but as I slow down to stop it starts to jerk and sometimes it will just shut off coming to a stop (why does that happen?) However, a couple times the bike was able to stop and just keep idling, and then I was able to just take off again no problem. The whole time I stayed in first gear since this is my first time riding, was just taking it slow.

I'll also add that I checked the battery voltage a few minutes after shutting the bike off when done riding, and it read 12.35 volts, so I put it back on the charger.
