Hey guys, finally get to post something in the Jap forum! Just picked up a 1997 Yamaha RT 100 as a first bike for my girlfriend. Not sure if it exactly qualifies as a "mini", but it is small, about the same size as the Suzy DS 80's. Since the lady is only 5'2", it fits her pretty well: It's a pretty basic little two-stroke. Air cooled, dual rear shocks, drum brakes... looks like something straight out of the 80's! As of right now it starts and runs for a bit, but will die if you give it any throttle, or all by itself after 15-30 seconds or so. I have no doubt the carb is totally gunked up, as the PO says it's been sitting for 4-5 years. This bike has Yamaha's "Auto-Lube" oil injection system on it, with which I have zero experience or info to go off of. I also know that he has pre-mixed gasoline in the tank, so the bike is most likely using way too much oil. So, can anyone explain to me how the oil travels through the system? I can see the line at the bottom of the oil tank that runs over to the right side of the engine and goes into the crank case, I'm assuming to the oil pump, and there is a small line that runs out of the same spot up to the bottom/side of the carb. So is oil fed into the pump and then distributed back up to the carb? How do I know if the oil is flowing like it should? I'm afraid to run straight gas in the tank in case the auto-lube system is gummed up. Also, do I just clean the oil passageway in the carb the same as the fuel passages? Do I have to bleed the oil system or anything? Probably a lot of dumb questions, but every other two stroke I have owned has always been pre-mix setups, so I just want to make sure before I go ramping this guy up and down the street. If anyone can point me towards a service manual for this thing that'd be awesome. I found a download for the owner's manual, but no service info whatsoever. Thanks ahead of time, guys, much appreciated as always. Lots more pics to come, as well. The GF wants to work on her own bike, so I actually have time to sit back and take some pics for once =P.
