i like to start off by saying that this 750 that i picked up is rough. very rough, but it is good where it counts. Got it for 400 bucks. i now understand why it has such a devoted following. it really didn't take a whole lot to get it going.
i pulled the plugs to check for spark (notice the washers on the 4th plug), no spark, cleaned the points, added a small 12v battery and voila! spark. according to the plugs the bike has been running very well up until it was stored 13 years ago.
next was fuel: i pulled the carbs and checked them and of course they were pretty bad and needed a good cleaning. so i cleaned them up with a bit of carb cleaner, tooth brush, a piece of wire, and compressed air. all the passages were cleaned out and i reassembled. of course i had to break something: the float bowl drain screw snapped right off!
i installed the carbs, hooked up an aux. fuel tank and started kicking. after a few pops and sputters and some disgusting black smoke she fired right up! what a beautiful sound too! these old bikes a breeze to work on and i now understand why they are so popular!
