TRX450R Valve Adjustment HOW-TO

ghott · 02-22-2007, 07:27 PM

This is my own personal Valve Adjustment HOW-TO write up for the TRX450R....complete with detailed pictures.

Its long winded...but its complete and, I would venture to say, idiot proof.

It outlines the tools you need, steps, precautions, and detailed pictures.

Special thanks to all of those involved behind the scenes!

Nice ghott! That should help a lot of people! That must have taken some time to put together?

wow, that made the valve clearance issue a cake walk. i only have one question...if i take the head off what all changes from your instructions. it would be sweet to see something like that to do a complete top end job....new piston.... :)

thanks again for the great write up! we need just a couple more to complete an entire engine build....then we will all be too smart for our own good.

good write up man kudos to you i wouldent be able to do that... hey was their a reference to the decompressor arm and how to adjust that? i didnt see it on their but it is also late for me and my eyes are fuzzy. what are the specs for the decomp arm??

ghott · 04-14-2007, 05:23 PM

For a complete top-end tear down how-to: http://www.rockinhorseweb.com - then click on "TRX HOW-TO GUIDES." - then click the Piston Install.

Use a compression gauge to adjust the decompressor arm.

The valve adjustment page doesn't work anymore. Does anyone have it saved somewhere?

ghott · 04-15-2007, 06:55 PM

Should be working now....My university had ISP problems this weekend.

Let me know if it is still not working, and I will rehost the site....I have it saved in it's entirety.
