2. Spark plug cables in bad condition and leaking.
3. Spark plug gap too close or too wide.
4. Faulty ignition coil, module, and or sensor.
5. Battery nearly discharged.
6. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
7. Intake air leak.
8. Water, dirt, or rust in the fuel system, carburetor and/or filter.

if you are realy lucky and the bike wasn't going to fast and who ever was riding it pulled in the clutch quickly.. then you might get away with just a top end
but no two ways about it the engine has to come apart.... to do it properly special tools and knowlede required you will need to find a shop

Stock size for the slow jet is 35. Some guys put in 38's to make them less prone to getting plugged. I would say that you still have gunk in the slow jets. Also turn the pilot screws out 2 1/4turns. If the exhaust pops and you have no exhaust or vacuum leaks turn the pilot screws in 1/4 turn at a time till it goes away.
Did you change the plugs and the air filter? How about checking and or replacing the vacuum lines?
You might try a full bottle of Techron fuel system cleaner in a tank of gas. It may clear the problem up.
I had to clean the jets on my 1999 I/S twice and it's not a fun job.
Hope this helps.

Turn the clutch adjustment bolt towards the clutch-lever surface all the way in-not too tight. Feel the lever pressure as crisp, engage the first gear, and see if the bike moves when you engage; stops when you dis-engage. Give the adjustment-bolt a couple outward turns, and see. Repeat procedure as necessary.
