Friends, My friend mechanic Carlos was right, you disconnect the brake pedal from the master cylinder, and the master piston shifts abt 1 or 2 mm, and there is a sweet spot, and the oil just dribbles in, without pumping it. All this wisdom he shared with me during his lunch break, sitting on the garage floor, eating his rice and beans. He is a good friend, I donated my old CG Today 125 to him last year. Now then, I got pressure on the rear caliper, and pumped out the caliper piston. Then I cleansed it, took off the rubber boot. The groove on the piston had some rust, so I used some waterproof fine sandpaper. blah blah. The thing is that the rubber BOOT does not fit anymore. I think the heat treatment enlarged it?? Anyhow, it seems about 6 mm to big or wide for the hole it is supposed to go into. Now I got to find out where to get this boot, might as well change the piston, there are some scratches on it. Who done it? All this junk reminds me more of a toy than of a 48 horsepower powerful motorcycle, that can get you according to the latest tall stories, a good 115 miles per hour. It is just too vulnerable to my taste. But I am grateful for the six San Miguel beers a kind, merciful Philipino captain gave me. Boy, did I need them! Now I need ideas from the infinite wisdom latently available on this site, but seems a bit recalcitrant to come forth. It seems more a bike to talk about, than to ride, but that s just my take on it today, and may change again soon. Cool it, Jacostarica.

Was it a pretty hot day out? If so, it *might* be the same thing that one of my old Seca II's was notorious for... If it had less than half a tank of gas and a vacuum would occasionally build in the tank as it got hot. It was pretty rare, but it generally happened if I started with a full tank in the morning when it cool, ran half the tank out and parked it, and then it turned out to be a hot afternoon. If I then ran about 30 miles or so, the thing would act like it was out of gas. I'd flop the petcock to prime (basically changing from vacuum fed to gravity fed) and run a mile or so and flip it back to ON. Once I decided to open the tank and see how much gas was actually in there and I had to pry the gas cap off due to the vacuum that had been created. It's a long shot, but if it happens again, pop the fuel cap and see if it sucks in air. Be careful that your face isn't anywhere near it though... I've had other bikes that would build up pressure and blow gas out when you popped the top. Not really a good thing if you happen to be looking at it when it burps.
