What Happens?
I am part way through a valve adjustment and wonder what effect not refitting the plastic filler plate above the front valve cover would have in relation to the running of the VTR?
The conditions I ride under are mild to say the least and very rarely does the VTR experience rain.
Is the filler there to keep water , mud etc off the motor , or does it protect the carbs from debris or insulate them from the heat of the motor?
Is it vital to the air flow into the air filter via the Snorkle?
Anyone on here running without it?
What does it do I wonder?
What purpose does it serve ?
Thoughts please guys!

I've also wondered this in the past without ever getting a straight answer on the effects of removing it. I believe at some point someone said its supposed to reduce wind turbulance going to the snorkel but I have no idea.

I just recently took it back out. It seems like it would let more air get to the filter for the FIL mod. I noticed ZERO difference. But my bike is now lighter

I did a lot of reading on this last winter from both vtr sites. It's a turbulence issue. Everyone i read who tried it noticed a big (negative) difference in how their bike ran at freeway speeds because the airflow wasn't smoothed out by it... So, i reinstalled mine.

I tried cutting a hole in said shelf and the bike developed a surging at highway speeds. Closed it up and problem went away. Now, this may not be an issue for those running the FIL mod (since it's getting its air from higher up), but those that still have a snorkle in place, keep it in there......

Factories are in the business to make money. There are very few parts that are included that are not needed because that would cost money and profit. (except of course for the PAR system and the anti-rattle gear) My thought is if it came with it i put it back on. It might be channeling air through the radiators I don't know.

It is going back in for a couple of reasons.
1 I spent ages getting the thing jetted right.
2 I believe that it has an effect on the air delivery.
I want to do the right thing by my bike and was curious if there was a definitive answer to my question. Sort of like an oil thread, anti rattle gear or carb heater hose question I guess.
For now it stays !
