ok guys, made a big boo boo on the we, basically i was cruising along at 60 along wickam street near normanby 5 ways on sat, and the bike all of a sudden became really sluggish and wasnt responding well at all. Got to the lights at the 5 ways and the bike died, i thought fark wtf is going on. *Bing* light goes on and i check fuel level, the fkin tank was bone dry, like nuthin and it was on normal tank level not reserve WTF?? i thought i had 3.1L in reserve but apparently not, as when i swithched it over it wouldnt start. so my question is, how many k's should i be getting outa 1 tank, as i filled it up and have done around 60ks and the tank seems to be 1.3 full, which sounds really low to me. advice?
about 150 k's is normal pre-reserve (some get more, some a bit less). There should be 2-3 litres in reserve. Are you sure you had the fuel cock set to normal, and not reserve? If you definitely did this, and still ran out then there may be something 'odd' in your tank. Could you hear any sloshing if you moved the bike side->side? I ask that because it is very difficult to see to the actual bottom of the tank. Do you have a fuel pump? If not then this may be the problem. Without a fuel pump you can't use the full tank - you will always have about 2 litres that you can not use. This is because the bottom of hte tank will not gravity feed into the carbies and you need a fuel pump to get it there. Many fzr's have had their pumps removed because of problems, though no one has been able to tell me what these problems actually are...
Hey, ummm.. on the topic of fuel... i just got a carb overhaul and it seem to have fixed my problems.. i dont kno what he did exactly but yeah... he also told me to use 98 premium fuel.. said its better for the bike. jsut stay away from optimax.. is this true??
Check that your fuel lines from your tank are going into the right inlet in the fuel switch. (Reserve to reserve and fuel to fuel). In regards to 98 fuel, I beleive the FZR250 might have been tuned to run normal unleaded. The extra cost of the premium doesn't really warrant its use unless the bike is tuned for that fuel. By the way, I get to around 150-160km before I fill up.
Yea i havnt tried reserve yet. i'll give that a try too.. i use to get 160 ( full tank + researve) before service. now i am on 130km and still on the ON switch. so i'll see when the ON runs out and i'll have to switch to reserve. if i get to 200km / tank i'm happy. i think i'll use 95 premium just to be on the safe side?
So could someone tell me again, on the 2kr model, the fuel tank capacity is 10L, and of that the reserve is 2L? And on the 3ln its 12 - 2 reserve?
reason to avoid optimax - it includes detergents in the fuel to clean the fuel system while riding, and these can hinder performance and cause problems if not properly burnt off during riding (i.e. running rich). This particularly effects carburetted engines, and efi should adjust the fuel mixture so it doesn't run rich.. From a press release (bold is my own emphasis): Although Shell Optimax is compatible with most bikes there may be a requirement in some cases to make slight adjustments to the engine such as changing spark plugs, and reducing the size of carburettor jets, or a combination of both. Bikes used mainly for city running (and therefore subject to considerable stop-start running) are likely to need such adjustments when changed to Shell Optimax. Some fine adjustments may also be required to ensure that when the bike is hot it runs smoother and with better overall performance and in particular there is more power at the top end. In short - don't run optimax unless your bike was specifically tuned for it or if your bike has fuel injection (and even then people found problems with it). See the press release for more info. The fzr250 was originally tuned to run on regular petrol. However, if your mechanic has overhauled the carbs it may run better on premium. Try premium, try regular, try the in-between stuff (i.e. 95 octane) and choose the one that you feel your bike runs best on (performance and mileage). If there is no difference - go for the cheapest option.
info found elsewhere on this site... 3ln: Fuel tank cap; 14ltrs (11.2 + 2.8) Fuel reserve amount; 2.8ltrs 2kr: Fuel tank cap; 12ltrs (10 + 2) Fuel reserve amount; 2ltrs
BEST ADVISE EVER!! <!-- s --><img src="{SMILIES_PATH}/icon_smile.gif" alt="" title="Smile" /><!-- s --> it seems like all of you are in other states and non in Sydney!!! maybe i shoudl move up!
so if my bike was running rich would it be possible that i could be getting only 70km~ out of a tank, or does it sound like i have another problem?
The only reason optimax has the reputation is cause it was the only high octane commonly available and being marketed in the mid 90s. You run any 98RON oxygenated blend in your fzr and you are wasting money. Your bike doesn't have the smarts to advance the ignition and adjust the fuel curve to best practise stoichiometry. The type and octane of the fuel you choose to use is irrelevant. Your bike should be professionally tuned to whatever fuel you choose to use. It is factory calibrated to 89RON so use it, want to run higher? Spend the dollars and have the ignition advanced and carb calibrated with a sniffer, otherwise you waste good money on no gain.
I'd be putting my money on a major fuel leak somewhere. Never, EVER did i see below 100km's including reserve out of a full tank. Even when the little 3LN-3 was running pig rough and in need of a service. In all honesty i'd say anything less than 130km's and the bike has issues. As for the 89, 91, 95, 98 RON thing. I alternate between ULP (89/91), ULP+ (95) and PULP (98) depending on what is available, the price of petrol and the colour of the sky. I've found my FZR1k has the best performance on the 95 RON stuff, yet there's no difference between 91 & 98. Therefore i put it down to a placebo effect and just stick whatever is available - unless there's a petrol tanker filling up the station in which case i don't go anywhere NEAR that station for 24 hours.
It's either running so super rich it shouldn't run or leaking. When you refill it, how much petrol are you putting in??? I get between 160 to 200+ out of 10L depending what type of riding I am doing. Generally closer to 200 on long runs.
