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.

Lol I am still trying to get this quote thing to work. Anyways I'll turn it on tomorrow and try to pin point where the actual sound is.
Wow I have so many questions!

When I bought this atv it had the stock rims and tires on it! Woo bad shape they were in. So I just bought some steel 12" rims and 25's tires.
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

!!!Wow!!! I never knew that! So I should usually start in 1st and use super low for climbing hills and pulling things! Is there a way in changing this to make it faster in super low?

no..thier isn't anyway to change the gear ratio..well..there is..but..you would have to split the cases.and swap out the internal gears..and it's not worth it..lol...and your tapping noise you hear..is most likely your valves that need adjusting.

I have the owner's manual. How do I go about and adjusting them?
i don't think the owners manaul will cover this..but..you will need a filler gauge set..a 10 mm socket or open end wrench a 17mm socket i think is what the flywheel calls for ?..remove the spark plug..remove the slotted inpsection cover ( on the flywheel side ) remove the flyweel slotted cap..remove the ex and intake valve covers..should have a 10 mm bolt on them ?..with the 17 mm socket..turn your crank where your piston is on TDC ( top dead center ) make sure your on the compresson stroke ( turn the flywheel backwards..while watching the intake valve..if it moves..then your on top dead center on the compresson stroke..loosen the intake and ex valve 10 mm nuts..with the filler gauge ( the right spec'd one )..stick it under the round valve bolt..turn it down to where it barely touches the filler gauge..then tighten the 10 mm nut back down..re-check with filler gauge to make sure you didn't over tighten the valve..do the same with the ex valve..also do this when the engine is cold..DO NOT ADJUST WHEN HOT OR WARM !. watch the flywheel's mark..line it up on the outter case line..this is to show you your piston is on TDC.

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.

Alright I just got done checking the actual noise that was making a tapping and clicking noise.... lol it's coming from my carb. every time I give it gas just for the initial start or in gear it does that clicking. I did put my head close to that super hot engine! from reving it numerous times I really think it's coming from the carb. Any idea why?

it's not your carb..thats the intake valve you hear..adjust the valves both of them like we said to do..this will solve your '' ticking ''.
