Strange bits on my new pit bike roller

[fray_xsport]

I picked up a pit bike roller yesterday and have found a few strange things on it, nothing thats a problem tho im really happy with it. First there was a microswitch on the front break lever which clicked everytime i put the brake on. Then there was an extra cable on the clutch side with just an on and off position and lastly i cant pump the front tyre up because there is like a milky stuff in it!


I know hes proberly had a puncture on the front a put that gunky stuff in to repair it but i havent a clue what the other two bits did :confused:

Anyone shed any light :thumbs:

switch on the front brake is for a on road bike brake light switch and wires on the clutch are normaly for electric start pullclutch in then press start button for it to start, as front inner tube take the valve out and have a look:thumbs:
