Round 4 from rowrah

[Fladdem]

I'm trying to prep my pitbike for racing but I'm struggling with a catch can....
What does it do?
Where are people connecting them?
Does it need some sort of special fitting to the hoses?
Does it need to be sealed? If not, what's the point of it when an off will still result in whatever's caught in it spilling onto the track?
Does it collect both fuel and oil?

I was also thinking about lock-wire, what needs doing?
Is it just the sump plug and filler cap?

Should I take the sidestand off? I thought that that might dig into the track as well in a spill.

Would I need to remove the brake light and holder or just tape over?

The bikes got no baffle, my daft mate took it out and threw it away , would one of the cheap universal baffles fleabay, modified to fit, be OK?

I've been reading this repeatedly and nothing springs out

I think I best just try to head to Whilton Mill seeing as it's only in Daventry and see what the others are doing.

I'm having more fun than a well-oiled midget.

The idea is to catch oil that may come out if the bike is upside down.
On my M2R it has two hoses - one goes in to where the dipstick would normally be and the other ti what I would guess would be an oil breather.

I presume the idea is that it's at least at a different angle to the engine breather - so if oil goes into it, it won't immediately get on to the track.

Have to lock wire sump plug, not sure about filler cap.

Haven't seen any regulations about brake lights - they're all plastic these days, so shouldn't be an issue, bar letting people see when you're braking!

NMRRC is ok with louder bikes, as opposed to Matchams where they need the REALLY quiet c90 exhausts.
