Mine we left the Funduro jets(133.5) and needle settings in for starters. Runs fine, good economy, although lacking the grunt.

Will change when I get to the rebuild

Fortunately my Needles and slides are 100%. Had an issue with flooding though but have adjusted the floats and it appears to be sorted now. Also replaced the O rings and gasket's on the bottom bowls. What is considered a good or average consumption on these bikes

Pretty. Its not the parts that are the problem, the housings they fit into wear out. Mine had all new parts, we spent hours on settings and it still over fueled that I only got 9km/l on it.

16km/l considered good. On my trip in April it varied between 16 and 19.5km/l depending on terrain. Oil at 420km/l

I get 13km/l. I guess a little heavy. Maybe it's just the way I ride it. It tends to bring the hooligan out in you

I have a ZX10 pipe on mine with a lovely growl. You can't help but twist the throttle. Note also that I have 133.5 jets in the carbs and not the stock 140's which could account for my fuel consumption. Looses a bit of the grunt though.

I need to re-do the top end on my bike. Can die head and barrel be removed without taking the engine out the bike.

It runs like an electric sewing machine, but I need to sort out the violent oil usage
