Hey There All! I'm new to this forum but have always had a love for Yamaha's in general, I have had a TZR (250 2 stroke) previously x2 and loved them, had a brief stint on a Kawazaki GPz550 (was short on cash and just wanted a bike, any would do!) but not bad for an old cumfy lounge chair on 2 wheels! And I am now the proud father of a '94 FZR250RR 3LN! Anyway, my question is what sort of k's do you all get to a tank of fuel, country & city riding? I am currently only getting high 120's in the city & high 170's in the country before hitting the reserve (I haven't been game enough to push the reserve as far as it can go) I know bikes like the CBR's, ZX2's etc and even my old TZR would get close to 200k's per tank in city riding! Are FZR's a lot more thirsty than other makes & models? Next question is what can I do (preferably without taking it to a mechanic) to increase fuel efficiancy? I have tried adjusting the air intake screw on right side of bike (not sure of proper name) but that affects the idle speed too much if screwed in too far causing the bike to stall. The carbies have been balanced probably 2mths ago and it has only done 1000k's since then. Please help! (sorry about the essay!)
I get between 130-140 pre-reserve, and can stretch reserve up to around 160. Outside city I can get over 200 with reserve. What do you tend to cruise at (rev-wise)? When I first got my bike I enjoyed cruising around like a bee, with my revs constantly above 10 000 (usually around 12 000). When I did this I was getting around 130-140 with reserve max. I soon learned that was a poor way to ride (and not very economical). Great for acceleration, but puts a lot of hard work on the engine (more repairs, less life), and more a lot fuel. I now cruise between 7000-8000 revs, and only when I need to accelerate do I get to the higher revs. Aside from that I can't think of much as you said your carbs are tuned properly...
I do tend to cruise at around 10000 - 12000rpm, the bike feels alot more responsive at that range without reving the crap out of it, but if cruising at lower revs is going to significantly decrease my fuel efficiency I'll give it a go. Thanks
It is a lot more responsive at that range. The optimum rev range for acceleration is somewhere between 12-14000 revs on the fzr (which also corresponds to when the exup is fully open). However that isn't the best for fuel economy. So I guess you will have to pick and choose which you prefer. I personally prefer the fuel economy, and then get to the higher revs when I need them (sometimes dropping back a gear or two), but then once I am steady again I am back to around 7-8000 revs.
So 140-150 km per tank is normal? I was expecting to get over 200 out of it, then ended up running out on Epping Rd and having to switch over to reserve while stalled on the side of the road. The fuel economy they mention in the specs sheet is so incorrect!
fuel economy that is stated on factory specs often comes from testing either on dynos or on tracks where the speed is kept at a constant rate. The fzr isn't too bad for fuel - suzuki acrosses get around 160 before reserve, and the cbr 250rr I have ridden with a few times gets only a fraction more fuel/km than I do. I think the main issue is simply the size of the tank (10+2 for 2kr, 12+2 for 3ln) - I am able to get 15-18 km's / litre out of mine which is respectable given the class of bikes it is in.
and what class is that, boz? My mate's CBR250 98 model gets over 200 he reckons... maybe his is slightly less thirsty being a newer make than mine, which is 92. Not having the side fairings on wouldn't make any difference would it? Would you think the smell from the engine, eg. oil and petrol fumes, would be worse without these on? I"m riding around a la streetfighter at the moment, as I need to get the fairings welded/painted (cringe - more money going into the fizzer!).
Fizzer i did the same when my fairings were getting repaired!, atm I can get about 160-180 out of my tank. i think i hit 200+ once.. but it was with the exup value operating and i was riding on heaps low revs.
The 250cc sports bike. It all depends where your friend gets 200 k+. If it is purely city commuting that would be pretty impressive - but as you said it is a newer bike so perhaps that is where the difference lies. I have several friends who ride acrosses and they tend to get ~180 from a tank when commuting (14 litre tank, as opposed to my 12 litre tank where I get ~160 when commuting). I also have a friend who commutes on a cbr250 and says that he typically gets around 170-180 on a 13 litre tank. Country riding I can get over 200 k's per tank. But then again there is one person on an across who gets 210 / tank when commuting. So there may be something to do with riding styles and also routes that people take to/from work. 160 / tank I consider pretty average. Given that a 12 litre tank (I ride a 2kr model) is the smallest of all the tanks on this class of bikes I expected to have less distance per tank. But they are all reasonably in the same km's/litre range.
Don't forget to factor in those double cheeseburgers as well. I'm one to talk, porking out at the seams. Oh, I'm 6'3" 155 lbs (on a good day I can break 158 lbs)
lol. 6'3" and at 155!!! I think you need to eat more of those double cheeseburgers! I'm 5'8" and at 150 lbs and am considered 'average' (see http://www.yourpurelife.co.uk/bmi_calculator.html. Think we should start calling you stretch...
I rated "Desirable" with a score of 19 on the link you posted. Try finding clothes for someone this skinny. 36" inseam is normally associated with a 40" waist, not a 31/32" waist.
Im desirable as well! i weight 185 pounds and i think 6'2 or something im 185cms tall. But i dont eat mc donalds i just eat too much!
wow i get like 300 + ks per tank and its running like **** might not help that i cant rev it past 9000 rpm but im fixing that i hope i keep the economy
hey guys i get about 160 - 170 kms per tank pre reserve. city riding, rarely rev it over 12 000rpm unless i have to.
