Ok, well I was talking with an old time mechanic earlier and we were discussing old tricks of the trade and he told me something that makes so much, and is so easy I can't believe I've never heard of it before. Anyways warning lights are a great thing, but when you're racing MX or XC as I do you seldom have time to notice the lights. So he told me to take the puke line from the radiator and splice into it and run a short piece of hose and zip tie so that it will drip onto the exhaust. This will cause smoking and steaming when it pukes and best of all you will still have the warning light operational.
