can anyone confirm this with their fzr250 or even any other carbureted 250 around the 1990s

also there is alot of knocking sound around the engine.. will a valve clearance and adjustment sort that out?

hey guys check this video out http://www.youtube.com/watch?v=aRXkZNkW5i4 this is my bike.. and this video explains better than words what my problem is.. is this normal for fzr250s? if not normal, can this lag/delay in revs be tuned out? if it can, how can i tune it out? it happens throughout rev ra...

hey S01 yeah fine tuning these bikes takes sooo long if your noob like me haha when you checked your float levels was your bike on or was just the battery on? (wondering if that makes a difference) cuz i cant get my levels THAT low with just the battery on.. im about 12-13mm above the line where im ...

hey thanks for the links guys!! really saved me time and helped me out! ok so did the carb sync.. not a professional sync because i didnt have vacuum gauges.. so i did it how one of the 600 boys did it on the wiki with the guitar string and feel! wasnt too much of a difference.. i guess my carbs wer...

hey every1.. so i did the floats but am still not 100% happy float heights 15mm from the gasket (at 45 degrees as to not push down on the button thing) float levels 13mm above the line needle clip position in the middle (haven't changed) idle air screw still 3 turns out exup cleaned and adjusted to ...

ok exup checked and adjusted.. took it for a ride.. felt the difference actually but still theres that delay at low revs under 8-9k.. still back fires at higher rpm

gonna try and get those floats sorted now!

hey don.. yeah exactly the 3lns are so awesomly rare they dont have a manual haha its so hard to try and incorporate the 2kr and the 400s manuals to the 3ln.. but yup ill try tuning the floats some more doing the exup right now.. the links GI posted are a real help THANKS.. the hole doesnt line up e...

hey GI i did check the manifolds rubbers.. they were split and were slightly restricting air flow into the engine.. i shaved the edges on the inside.. do u reckon i need to buy new ones? the leads are correct.. ill check them again.. check the spark plugs again to.. im doing the exup today.. let u k...

happy New year everyone hope you all hada blast! got my bike moving again. float heights all 18mm float levels around 10-12mm above the exterior carb line bike still doesn't start without me giving it throttle i think the idle air screw is to high might need to go go from 3turns out to 2.5.. am i ri...

gotcha George
i was reluctant to make and use the nifty tool but i guess il have do it

happy holidays everyone and have a happy new year

hey George yeah i found it haha i checked one and it was on the middle.. i havnt changed it so i think il leave it for now (ill open them all and check they all the same before i put it back in) ok i just wanted to ask now i double checked the floats 2-3-4 were 14mm from the gasket (inside the float...

Gotcha George. Yeah nah i dont recall there being anything to adjust with the diaphram and needle. strange as that guy says hes got a fzr250 3ln that is fully stock..i was assuming it was the same, though one of his jets it different to mine also.

so i found this thread while reading up on carb tuning

http://www.netrider.net.au/threads/fzr2 ... ng.135481/

the person mentions something about a needle being set to the second highest clip position. anyone know what hes talking about?

^ awesome!!

yeah ill do some reading and post up a tune that works well for me

cheers guys!

hey thanks GI

the thing is i tried the very useful links and it still comes up to the sign in..

Dave@fzr .. sorry im really slow.. got it thanks
