Evil 4 wheeler question

[thestud25]

I have a Honda TRX 90 with a noisy top end. I am pretty sure that it is a valve noise. I adjusted the valves but the noise did not go away. It is "clicking" like it is low on oil. I put the exact amount of oil needed in. Any ideas?

Thanks!

I would check the timing chain.

[thestud25]

To see if there is slack or what?

yeah.........

adjust the cam chain.

[thestud25]

Can someone paint me a pic. The cam chain is the same as the timing chain correct? If so, How do you adjust that?

what about valve lash? my CT 90 did that and it was just loose valve adjusters. I thought those chains had an autotensioner.

Here is a link I found from someone else. Had a similar problem. The TRX90 has a automatic adjustment.

Thanks, I will try and locate that, and see if I can make it a little tighter.
