How heavy is ur shee on juice? I got fmf fattys and boysen reeds. . .and i ride 4 about an hour on 50bucks. . .fast and slow jst mesing around. . .sy suip soos n vis ek se! Lol
I have no clue dude. Somehow have have this idea of +-6km/l. My Yz gave me bout 4. That I measured. My friend with his kdx emptied about half his tank that day. The YZ had a tank and a bit. hahaha.
Haha holy cow! 4! Thats insane! Damb!
Km/l? I prefer to work in minutes/litre

My laaities yz125 uses about 3,5l of petrol on a 32km loop and that is open throttle or racing mode.
Roughly my other sons banshee with fmf,vforce and ported used between 8 and 9 liters of petrol on 32km loop also open throttle and racing mode.
My new 2006 back in the days with pipes and filter gave 10km/l...
Seriously most off roads should be in the 8-10 range otherwise something is clearly wrong....
My new 4mm uhhh yeah, lets just say, I will never be able to run a stock size fuel tank again....

My YZ was runnig VERY rich, Oil would drip from the exhaust, but I wasnt really clued up on jetting, so that didnt bother me.
I do an hopur of hard riding on the flay track and there goes a full tank....
klaus just remember that yz 250 of yours had a 5-8 mm stroker kit. so sy is baie sterk gewees en daarom dors. my shee is very dors 2 but that is just when u ride hard,
10km/l liter is biq pushing it jy sal nie in 'n 60km enduro met die gewone tank kan maak op 'n stock banshee nie. al die enduro's in die land het 'n refeul op 60km +-.
