OK, so the boss was late coming in to the office so i uploaded this while no one was looking :working:

Its not the best ever quality video so I will have a rework of it tonight at home and see if i can improve on it. In the mean time have a squizz at this test run on a gravel road i ride everyday on my way to work.

Hmmm how about a thread of vids that show the route we go to work. I am lucky enough to ride to work everyday, and have a choice of off road routes to take, thoughthe one in this vid is the one i use most often as its the quietest. :riding:

Yep, all I got from that was envy :drool:

A plug chop is where you ride at a constant thottle possision for 1-2kms, hit the kill switch & pull the clutch in at the same time then take your spark plugs out to see if the engines running rich or not, then do the same in a different thottle possision.
It's just a way of making sure your needle clip is in the right groove.
& yes, it is a twat of a job when the plugs are hard to get to.

The only other thing I can think of that gives high fuel consumption is a dirty air filter, but I suspect you have fitted a new one.

Hope the new fuel filter cured the starvation, now to cure the thirst :scratch:

Don't really know much about the S10 Charlie but it sure sounds like the float heights are too low... you sure they're ok??

Nice riding by the way....

Did you check your flow rate after the filters or from the tank petcock? it certainly sound like fuel starvation. :scratch:

Got more balls than me doing that speed on dirt. :rtfi:

Best ive done is 265k (two up on tarmac) :biggrin:

265 with a pillion :omg: .... fuckin hell :hss: mate, now that takes a brass pair!!

I tried the very same run on my way home, and it was still running in top form :yess: So what has changed?? Well i filled the tank to the brim, I made the tank breather hole a little bigger with a hammer and punch, and thats it. However i will have to change my rear tyre tomorrow as I am running my knackered Metzler Karoo on the smooth bit between the treads through the corners at this point. Tis very loose on the tar :falloff:

once I have my new grippy on at the back I will have another go at a top end run and see what the results are. Holding thumbs that it is something as simple as a vapour lock in the tank??
