Hearing tapping noise.

I just got done riding all day today and yesterday. While riding I happened to hear a tapping or clicking noise where the filter and engine is. So I rechecked it and held the break and reved it a little and heard it again. Put it in neutral and still heard it. Any idea what this is from?
Thanks!

96 Honda TRX300 fourtrax



Another question is I did a little tuning to my clutch and ended up screwing the nut and tightened the screw and lost order in where it was. Could this make that noise?
I also found that it doesn't have the power or take off like it did before I messed with it?..

Does the tapping noise sound like it's coming from the top of the engine? The valve clearance may need to be adjusted.

To adjust the clutch free play, loosen the locknut and slowly turn the adjusting screw counterclockwise until you feel resistance. Then, turn it clockwise 1/4 turn and then hold the adjusting screw, so it don't move, while you tighten the locknut.
I can't tell but when I put my finger on the right side of the cover I can feel it from there. Where the oil filter is located that and looking towards the front of the atv the cover that says honda on it. That's where I hear it and feel it.
That sounds like it might be toward the bottom of the engine. I don't really know what that could be without actually hearing it.
I noticed that my atv of course works harder but for some reason the 1st gear is I dont know how to say, once you take off or press the throttle about 4 miles a hour you already have to change it.. That would mean that I have a very low gear ratio?
Yes, first gear is actually "super low". The gears are as follows:

Super low

First

Second

Third

Fourth
Is there a way in changing this to make it faster in super low?
No, no way that I know of.

Looks like Shadetree covered it pretty good, but I will add some pictures. LOL. Here are the instructions from the Fourtrax 300 repair manual. Like Shadetree pointed out, make sure you adjust the valves on the compression stroke and while the engine is cold.

Man you guys got this stuff down! I didn't realize how much work that is. I think I can do it. I would hate to have screwed this up. Where do I get this feeler gauge from?
after 13 or 14 years of working on these..you learn as you go !..feeler gauges can be found at any auto parts store..even wal-mart for that matter.
If you can find the feeler gauges with the angle tips it will make things a little easier, but those kind can be hard to find.
