15f valvetrain noise?
My 15f seems like the valvetrain is a little louder than it used to be? What is the valve clearance supposed to be on these? Then again I may just be paranoid it only has 22 hours on it. Over all I am very pleased with this machine ( just needs a little more topend )

hard to say. If you want more top end start buyin some parts!

did the intake, it seemed to help a little ( did make it louder)
Nobody knows what the valve clearance is supposed to be?

My advice is to get sponsons. They make the biggest difference for the money on the 15f. I do not know how agressively you ride, but sponsons are adjustable and you should be able to find a "confortable" setting. I love being able to rely on my boat to just keep turning without breaking loose from the water until i either stop turning, or get thrown off from the g forces. About your engine noise. If the boat hasnt been modified before you got it, and you havent been tinkering around in their. It should be fine. The 15f has a hell of an engine in it. Ask anybody that owns a larger displacement ninja sport bike.
On a side note to Aaron. Where do you have your sponsons set to achieve max speed. Mine are all the way back because I like the way it goes through corners that way. Just wondering.

All mods will help. Look in your manual to see if it lists valve adjustment settings.
Speedjunkie- I have stock sponsons

If you have a Owner"s manual its on page 120. Intake- 0.15-.024mm, Exhaust-0.22-0.31mm. Usually the clearance tightens up on a ohc engine, it doesn't increase.
