I've done it
Forgot that I'd switched to reserve just before I put my bike away one night. Next day the bike spluttered, reached to turn the tap to reserve....Bugger,F*ck & Shite.
There was a petrol station about a mile away, so I started pushing, it was a GSXR750WR (not the lightest of bikes), it was fuggin hot, no shade and uphill all the away, I was sweating like Cameron reading a Rebekah Brookes Text.
Luckily a van driver going home from the local motoX track stopped and offered me a couple of pints of of 2 stroke premix, refused any payment and wished me luck.
Bikers hey? they're fukkin ace!!
Filled up at the garage, and then kept topping it up every 50 miles or so to dilute the 2 stroke, no lasting problems.
I've now got a warning light on the speedtrip, and panic when it comes on, I don't want to do it again.
