Hey everyone! First post on the forums here, and it's mostly because I'm stuck big time. I have a '73 G5 100 that I just turned over 3000 miles on. I've been having issues about every other year I've had it. The bike is pretty much identical to the KE100. Last year, the bike was getting so hot that the fuel was vaporizing before it could reach the carburetor, often bubbling up in the line. Threw in the next step colder plug (BR9HS) and the next step larger main jet. The bike ran okay for a while. Most recently, the bike was running terrible/intermittent. Found the points were corroded and the condenser was only making 2V AC. So threw in the new parts and timed the bike with a timing light (when a guy at work helped me initially time it, it was actually about 10 degrees retarded). Also happening right as we speak, the tank is rusting and sending sediment down to the carb. Luckily I installed a fuel filter off a snowmobile that a buddy gave me. I would like a plastic tank if possible. Fast forward to today. I threw new fuel line in (had some Tygon line that expanded and was pinching itself) and ran the bike around my subdivision. Ran okay until it started getting hotter. When I'd get hard on the throttle and up in rpm's, the bike would sometimes pop, and I knew I'd have to try to get home (just in case). Some instances it seemed it wasn't getting any fuel for a second or two. I dropped the bowl before I threw in that fuel filter and there was (and I say was) a large flake that I could bet the main jet would suck up and block off anything else. I would like to think that with this filter that nothing should be getting down to the carb. Crank seals? More ignition issues? Any ideas? This bike is a 50/50 learning experience and pain in the rear Thanks guys!
