1. Remove carburetors and intake manifolds.
2. Clean intake ports with Acetone, carb cleaner, or your chemical of choice.
3. Mark the short end center with a sharpie so you can line up the tube with the valve guide.
4. Cover exterior of tube in a thin film of sealant (i used loctite 510).
5. Slide into the intake tubes.
6. Wipe off excess.
7. Rotate to align the valve guide with your sharpie mark
8. Reinstall intake manifolds and carbs.
9. Allow time to dry, Loctite 510 takes a minimum of 30 mins. I gave it that before riding, it did not move after 30 mins.
A note that should be made, is that there may be a better sealant than loctite 510, a buddy of mine who is an ex indy car mechanic and now builds custom race cars suggested it so I went with it. If you know of something better I would suggest using it.
