EFI fuel consumption compared to carb (450 or 510)

A mate has a Kawasaki and reckons he gets another 35klm easily to the tank offroad.

How does the Husky compare between models with EFi and Carb?

Riding street my 09 TE450 is getting 50-52mpg. Off-road it's less and I haven't done the math, but I can do a 60 mile loop without the fuel light coming on. I should mention I'm a hooked-up torque rider, not a clutching, blasting, wheel-spinning rider. That makes a huge difference.

I recently got 37 miles to a tank with about 1/8-1/4 tank left in a race situation with the TE 250 FI if that helps any.

On my 08 te510 i get only 60 km offroad before the reserve light is telling me i have short time to get gas. this is powered up. with the o2 sensor i was getting 80 km. I run the bike with a 12th sprocket which also doesn't fuel consumption.

My 08 TE450 gets 40mpg (14kml) off-road with power up kit. I can easily do a 100 mile loop on my IMS tank.

Before I adjusted FB1 with iBeat it was getting about 30mpg (10.5kml).

Just did a 77 mile ride and ended up with 40mpg. Conditions were widely varied between a max of 50mph on asphalt/gravel and 5 mph cutting my own single track through burned down forest. I don't grab lots of throttle often (hello, torque) plus the surface was frost-ridden a lot of the way. I haven't done much following on my mpg with this thing but in more challenging single track I'll usually be down in the low to mid 30's mpg. Not an aggressive throttle twister, though.

I'll give it to you simple the 07 450te carb with i think an 8.5L TANK gets over the 100kms my 08 450 efi with a 7.2L tank gets about 77kms , the carbie bike gets better fuel economy than the efi and they supply a smaller tank , i'd love an 8.5 L tank for the efi as standard .

That's the beauty of fuel injection - get the software - click click click and you get better fuel economy (but less power/softer power delivery/ more engine heat) or not - all specialized to each throttle zone (20%, 40%, 70%).

On the 09's and forward no 02 sensor install is required, so it takes longer to boot your laptop than complete the "jet" change.

Keep good notes (fuel brand/ambiant temp/gearing/exhaust config/idle air bypass position/co1 co2 co3) and it's as repeatable as putting on your boots.

I've always had better fuel economy using the 02 sensor (plus tweaking FB1 FB2 FB3 according to the long term adaptation table) but just can't put up with the non-linear throttle response vs race mode (no 02 sensor).

I have an 06 TE 450, weigh about 250 in the buff and continually get 110 kms on a ride we do in the high country (big elevation changes) without having to go on reserve.
PS I think maybe the tanks are 9.2 litres on the 07's

Agreed. My 2007 TE250 could get 80-90 miles out of a tank and my 2008 TE250/310 could get 60. I am tired of complaining about the puny gas tank on the TE line so I won't do that here.
