Drain hoses??

There are two small hoses that protrude through the belly pan of my '17 RR. They were there on all my other RR's as well. This time when I had my oil service done (a new guy did it), the hoses were left inside the belly pan.

1. What are these hoses for? I assumed one was coolant overflow, and the other fuel tank overflow.

2. Is it permissible to leave them inside the belly pan?

Thank you.

yes.

No.

You don't want gas in your bellypan. Hoses should go through the bellypan, so liquids go outside.

I'd ask for a complete refund and warranty on a new replacement bike. This will clearly cause catastrophic engine failure.

Not helpful. Thanks for playing.

Thank you.
If your belly pan is sealed (no holes), like those used in racing then it is NOT ok to leave those hanging there. Why? Because if it ever rains, and you have water in your pan, water and debris will get sucked into your gas tank and cause all kinds of issues. This happened to a buddy of mine and it drove him nuts trying to chase down the problem. Something so simple cost him a lot of money and track time to troubleshoot. So do yourself a favor and cut those hoses to where they are several inches from touching the pan, no harm in it.
