my fzr has just got bad it wont start when it is cold i am yet to do a compression test but would it be the rings or just the valve clearences i had it dynoed and they said air was getting in somewhere but it starts fine when it is warm si i am unsure mechanic said it would cost around 500 to fix but he is a mate of the families so i get the family discount will it be just adjustment or will i need top end rebuilt any help would be appreciated , also need new front and side fairings as the idiot i bought the bike off bodgied them up way to bad now need them replaced cheers
hmm on the 3LN there are major problems with the rubbers connecting the air box to the carbs... they go hard... similar thing with the 2KR but it is mostly the air box that warps... so that is the first place I would look for an air leak
what model FZR you have... I will have both sides for the 3LN bouth in plastic and fiberglass... NEXT WEEK!!
its the model with the deltabox frame and the twin head lights i have replaced inlet manifolds all filters oil had it all professionally done by a mechanic but i had to stop somewhere funds ran out and a kid came along as well so know i am stuck to get it fixed and it is still registered it is a shame to see it just sit as i ride the cbr around so know i am trying to do it myself
you didn't really say what the bike runs like (ie. is the problem only with starting or does it run like crap too?), but if it starts fine when warm maybe it just needs more fuel at start when cold - definitely you should try full choke (and variations of that if it doesn't work) when starting from cold - maybe give the throttle a coupla twists before pressing the starter... simple stuff i know, and if you're well beyond that then move on to more difficult stuff (compression, valve clearances etc..)
i have got it running really rich so as to keep it running only runs on two cylinders till it warms up fully then fires on all 4 sometimes it will foul the spark plugs cause of too much fuel thats why i think maybe it is the valves or maybe the rings but it doesnt blow any smoke when you nuts it so i doubt it is the rings but i would like some input before i go and tear the thing apart and spend where i dont need to so any help would be great
check the valve clearences... they do go out on these bikes!! and EVERY body forgets about that!! AND doing a carby balance is usseless unless the valve clearances are perfect!! Also check out the idle mixture screw on each carby... it should be set to 2.5 to 3.25 turns out but if the jets are warn than each one needs to be individualy set... (lots of fun)
hey tbone i read in the other forums that you have made some moulds how hard are they to make and whats the process cause i have a couple of bikes i could do with making my own fairings hopefully be cheaper than bying them
You have shitty float heights and clogged carbies. A clean air filter and spark plugs mightn't go astray too if it's been awhile.
Simple, straight forward and honest. Means your dealing with a true 'no-BS' kinda person. <!-- s --><img src="{SMILIES_PATH}/icon_cool.gif" alt="" title="Cool" /><!-- s --> <!-- s --><img src="{SMILIES_PATH}/icon_biggrin.gif" alt="" title="Very Happy" /><!-- s -->
hey starter i have had the thinbg in the shop spent almost 1500 bucks on gettint the this serviced and tuned then took it and had it dynoed changed the leads anbd sparkplugs again dynoed again now at a loss thats why i am on here trying to get help but thats cool ill see what i can do and ill let you all know how i went
You need to itemise all the repairs/replacements made in the servicing and decide what WAS done at the shop and start from there. Put it this way, if your getting good spark, have good compression start looking at the fueling system.
