there's an owner's manual and a shop manual on THIS page
I get to the carb by removing the one large pivot bolt at the top-front of the engine. Once the center stand is retracted, the engine/swingarm will then drop to the floor. At that point the 4 reed-block/manifold screws can be removed and the manifold/carburetor assembly is removed as a unit.
But before you just let the engine drop down, you gotta disconnect or un-clip some cables, wires and stuff or they'll get stretched or broken.... the decompression cable, throttle cable, possibly the rear brake, and a few others.
Disconnect any obvious stuff and then, to be safe, pile blocks of wood under the muffler so the engine will drop only an inch or two. Pull the big pivot bolt out, retract the center stand and let the engine drop an inch, resting on the blocks.. and inspect the area, looking for things that need to be disconnected.
It may be easier if you have help the first time around.. someone to hold the bike and keep it steady.
After raising the engine back into position many things, like the rear brake cable, can be re-routed so they need not be disconnected next time... and this annoying procedure will go much faster.
