Hey i have a warrior with a broken valve guide i ordered a new one and was going to try to press it in myself any tips or tricks what did you use in the press to push it out or in? thanks

 

If you can find a good socket head bolt long enough to go through the guide and head put a nut and washer on it and pull it in with the bolt but you will probably have to get someone to reseat it I have done a lot these about half you get lucky.

 

Freeze the guide overnight and warm the head a bit. Pop it in quickly.

 

hey it worked great the new guide went great got the old one out with a brass hammer and punch the new one from yamaha was oversized so i heated the guide hole with the torch and tapped in the frozen guide went in like butta! how much cash did I just save! oh yeah!

 

Glad it worked out for you. I've done hundreds and hundreds of guides the way I told you to do it. Most went in like yours did. A few did not!!! At $75 bones a piece my boss did not like me to screw up!!!
Now have a good 3 angle valve job put on and your done. Double check the valve seal with solvent.

 

how do i do the solvent test? what type of solvent do i use? thanks

 

After your valve job is done and the head is assembled, prop the head up on a table with the port up. Pour some gas in the port and fill it up. If the valve job was done correctly, you should see no leakage past the valve. If you do, the valve job was not done correctly and needs to be fixed before the engine is put back together.
