I recently bought a bike for dirt cheap i thought ($1500), bike looked in good shape and rides great; but recently i noticed two things and I think it might be the same problem.
1st - When the bike is in neutral, and the clutch is released i can somewhat hear (faint) and feel (faint) a grinding noise (similar to when a car is out of coolant and the fan is trying to run); but when I run the bike it all goes away, or if im in first gear with the clutch pressed and stationary, no noise is heard and nothing is felt.
2nd, the other day I was riding with a bunch of guys who know bikes, and somebody riding abreast to me said they might''ve heard a wheezing noise usually heard when I take off (maybe first gear or neutral)
Question being, transmissions or gears (chain set) if needed, is it SUPER expensive or cheap enough to keep the bike around?? I''m not totally mechanically challenged, I know my way around cars and don''t initially see motorcycles being that different. Any suggestions to what I can do to pinpoint the problem so I can fix it??

I have an 05 with the same problem. Sounds like your STVA went out. Do you still have your butterflies wired open? I know how to repair the stva fixed mine, and saved hundreds....if your still on this post email me so we can get our bikes fixed. also check your kick stand sensor! This can malfunction and cause same stalling problems.
Sounds like the starter pawl has failed, a tab may have broken from return spring plate, it is a simple job for a home mechanic with a workshop manual, and won't cost too much from a qualified mechanic. However, it is a good idea to search on the net the appropriate models specifications so you have an understanding and are not taken for a ride, literally. Enter your bikes model and year into search, many diagrams and specifications are available to download across the spectrum.
The site below provides exploded views of all the parts on your bike, just scroll down to your model and click on it, then select any section (listed) for your bike. Cheers.
(great old bike Kevin) Sounds like selector forks, cams and/or grooves on selector barrel are at wear limits. Drain gearbox oil over magnet and check for metal splinters. Metal silt is common but shiny shards (very small) or foil like pieces indicate excessive wear. These old girls will still keep turning but will jam eventually. I suggest you pull selector mechanism down and either shim behind the cam plate spring or get replacement selector barrel. In the mean time thoroughly flush and give her some good quality gear oil of the lighter viscosity. Drive and driven shaft end bearings are often at fault on long haul m'bikes also. Replacement is inevitable.
well first off i never wash my bike....i hand towel everything and for the tough greasy spots i use Chemtool b-12 basically MEK, please wear gloves and mask when using this, it has highly toxic fumes!! Second when you wash a battery with water and dont wipe it dry it'll cause a drain across the top because there is now a water conection between the two...always keep the battery top clean. thats what probably happen to you the first time. first off let me know ..does it bump start o.k. everytime? and there is the possiblity that since you've be washing your bike that the kill switch is not functioning properly you might have got moisture in there. by a cheap trickle charger let it charge for about four hours leave the seat off and take a meter to it to see what the voltage is..it should be about minmum 12.6v that sufficient. 13 would be excellent. 12.2 means it dying. Crank it up to 4000 prm and watch the votage go to 15v and then regulate down to about 13v...if this checks out your battery system is in good shape. also make sure that all your spark plug wires are securely connected..it"ll only take one to mess it up. Yours is probably fuel injected and im not to much up on that so thats about all i can suggest or you can do something that i swear by that i used when i had bad hesitation and just a crappy ride and wont hurt your engine...by some Seafoam for an automotive store and pour about a tird of it in about two gallons of gas and ride a minimum of fifteen miles getting up to speed once in awhile to work this stuff through after ten miles it just kicked in and back to normal ever since...so now i use a tad everyweek to keep it that way. i now have only a 1% starting problem as opposed to at 10% non-starting problem....must still be a little dirt or gunk still in there.Just remember bump start it add some sea foam...it might ride rough for the first five miles but keep at it dont let it stall. later.
