if not did you clean the strainers under the float seats

did you check the float heights and movement.

Did you check the diaphragms for pinholes or splits.

and did you replace the fuel filter.

John.

No I didnt buy a rebuild kit. I didnt clean the strainers because they looked clean. Everything else I cleaned though. Yes the floats measured at 7mm and 8mm. The one that was at 8mm needs a new float valve. It had some corrosion under the rubber tip and when i was cleaning it off the rubber tip fell off. I then cleaned it completely and put the rubber tip back on. Its on pretty secure but wiggles a little unlike the other good one that is firm. The diaphragms were good. No I havent replaced the fuel filter. I looked inside the tank and saw some varnish but not too bad. I havent checked the petcock strainer either though. Although they are probably dirty, I dont think they are the problem. I do plan on cleaning and replacing all of that soon though. Im getting ready to go check the battery and do a load test.

The smoke is gone though. And it didnt smell sweet before. However I wondered this myself. I was thinking ok maybe when it heats up enough thats when the head gasket starts to leak and bogs the engine down. The level in the overflow tank was near the low line but still in between them.

OK, so I tested the fully charged battery. It's not the battery. Battery was at 12 something turned the bike on and it dropped to 11 something started the bike and it was charging at 13-14 something. It ran fine until it was warmed up pretty good and the same thing happened, bogged down and died. So Im thinking it warms up and the head gasket starts leaking? Hopefully the gasket expands and opens up the leak and not a crack in the head expands and opens up the leak. No smoke from the exhaust still. At least not enough for me to see in the dimly lit garage. However there was (possibly white) smoke coming up in front of the bike near the head light. I couldnt tell where it was coming from without some one reving the throttle while I look but I would assume the front cylinder. But I did spill a little coolant on the engine yesterday so idk. I guess I should do a leak down test. That will tell me. If it only leaks coolant when its warm will the leak down test still tell me if there is a leak when the bike is cold? I guess I could warm the bike up until it starts dying and then do the leak down test.

What else could it be? What other problems would only occur when the bike is warmed up? I really dont think its the carbs or clogged fuel lines or anything. I dont know how I would have gotten a head gasket leak though...the bike never overheated. Well, at least the light never came on and I never noticed any coolant bubbling in the overflow tank. Could it have been from when the oil level was high due to the gas in the oil? IDk...thoughts? Im good at fixing and replacing parts but Im not experienced enough to guess what the problem is.

Maybe some junk or pebbles fell in when removing the plugs? And 2 miles down the road, they caught in the valves and bent one? Or maybe its wedging the valve open?

Maybe that's why it smoking??

Just an idea, no idea how likely that is to happen.

Do a search for a broken piece of porcelain from the spark plug falling into the spark plug hole. It happens. And I'm not sure what bike you have, but dirt and stuff does tend to accumulate around the spark plugs, in my experience. That's why they always tell you to blow the debris off with compressed or first lest the crap falls in. If sh!t falling into the cylinder were not a concern, then why is it standard procedure to clean the area off?

I'm not saying that that is the answer, but I was just throwing the idea out there. The last I checked, an answer hasn't been found yet.

Sorry for the input.

Run it with the tank open.

Tanks has to breath in to let gas out. Plugged tank breather will cause vacuum in the tank to prevent gas from flowing. Also, when it heats up, bogs and dies open the bowl drains and see if its getting gas. Bogging out means its either starving or choking.
