I filled the header tank to the full mark and it has not changed at all.

Still the same problem...I let the engine run with the radiator cap off and topped off the radiator. I took it for a run and my radiator is now only 3/4 full....the reservoir is full. When I got back, it spit out a puddle of coolant on the garage floor. My radiator cap keeps it pressurized nicely, but it still likes to spit out of the overflow. I am sure that my cooling system is hooked up correctly. My temp never went above 70 C.

I will do that and go for an experimental run soon. Thank you!

I took the bike out for a spin yesterday and checked the coolant levels once I was back and it was cooled off. I filled the radiator before and after removing the cap, the radiator was only half full. What surprised me is that the bike didn't overheat (70 C all the way). My reservoir under the seat was full and I couldn't find any wet spots one bike, unless they evaporated. Even then, I did not notice anything after turning the bike off.

Update: I replaced the oil, coolant, and put good fuel in it. After a little coaxing, I got it idle nicely and let it run for 3 hours ( I made sure the temp was always in the normal range). I think it managed to clean out the minor gunk by itself because like I said, this bike was running before it was abandoned. It's been 2 days since my last post and she starts very nicely now...hot or cold....usually no more than 3 cranks if even that. Next thing to see is if I can tighten the clutch...it doesn't disengage all the way.

I honestly can't tell you. I received it from my neighbor...someone abandoned it in his yard, but it had a clean vin and I got a salvage title for it. I did have it running about 4 weeks ago, but that required copious amounts of starter fluid. Once it warmed up, it idled fine at 1150 and would start up if I turned it off.

It's on the frame below the tank on the left side of the bike (shifter side). I can hear a click in the carbs when I pull it.

I have a '94 YZF750R that won't start when it's cold. It turns over but never catches. If I remove the airbox and place my hand on the carbs to choke it, it comes to life, telling me that it is too lean and not getting fuel. Is this correct? I would like to note that the choke was fully engaged when I start it.
