Hey all, i am just getting into the fun world of motorbikes, and just got my first bike, a 1980 Yamaha xs400 special.
I know the bike will run, because i have gotten it to run! when i took it home and changed the battery, turned the starter, and it started right up, however it sounded like crap. After the initial start, she would always start right up and promptly die after the choke was turned off. So i thought it was a dirty carb.
Since then, i have changed the oil/filters rewired the old rusty fuse box, and done a few other small things. My guess of a dirty carb was correct, I took the carb off, disassembled it, and cleaned the living hell out of it (including getting a replacement for one of the jets). After i re-assembled everything, it was to my surprise that it wouldn't even start up like it used too with the choke on. It sounded like nothing was happening at all, no fuel was getting to the engine.
Using some engine starting spray applied directly to the carbs, she fired right up and burned for 2 seconds or so, till the starter spray burned away, then died. So now it is not getting any fuel. I know fuel is hitting the carbs, because the bowls are full.
Any ideas??
i would really appreciate any advice.
Thanks
