instead of guess work ?, why don't you down load the service manual from the site here, and start taking it apart. I would start at the front , pull the front cover off ( drain oil first ! ), and start inspecting the clutch, shifting area, and see if anything doesn't look normal ?. if nothing there looks bad ?, you very well may have to dig deeper into the motor ?. who knows ?..until you dig in 
.
.
if its that new ?, then its under warranty ?!..lol. if not ?..why worry about it ?. whats the worse that can happen, you take it apart, and can't get it back together ?..lol. don't be afraid to tear it apart !!!. you got us to help you, and the service manual, sooooooooo ??????????. it wont fix itself !. and changing the oil wont make a bit of difference to be honest. as for what oil ?. this is an open an closed case around here..same thing with winches, tires, some things are just left up to the owner
. myself ?..I run castrol full syn, 10w-30, or 10w-40, one thing you must know for a fact ?..IT MUST BE MADE FOR WET CLUTCHES !!!.
very well could be the cam chain. loose valves, someone been in the front cover already ?, I see a lot of yamahabond sticking between the front cover and engine case...lol. crank it up, take a long screw driver, put the end all over the engine, starting at the front cover, put your ear on the handle, listen, sound loud ?, move to the top, at the rocker box, same thing. I say start with checking the valves. there is a great sticky in the repair section by me explaining how to set and adjust valves on all 4-strokes ( my method ), very good info, you should read it
.
you need a clutch cover gasket, please do not use hondabond or yamabond on the front clutch cover !
.
unless your valves are not adjusted right ?, then a new cam chain, and chain tensioner will solve your problem
.
check the friction disk, clutch arms, replace if needed ?, yamabond/hondabond, clutch puller tool. cam chain, chain tensioner, air impact gun to zip the nuts off, 1/2 drive,27mm deep well impact socket to fit the clutch nuts. this should be all you needmatter of fact, after you install the new chain, and tensioner , go back and re-adjust the valves
Oh, I adjusted those valves perfectly. But will for sure check them again after.Lol, looks like I need a clutch puller too and some Honda bond. Is that it or do you recommend anything else well I have it apart. Will obviously check all the clutch disk clearances as well. Thanks :grin:grin

Ok so here's the update, got the new Honda can chain and tensioner and installed them. The old tensioner was completely maxed out so was probably still good but I changed it out anyways. Installed the new parts,put back together used some Hondabond on the case, filled with oil, READJUSTED VALVES and started it up. No noise sounds perfect now and way smoother. THANKS A LOT EVERYONE for the help.
