hi there, it could well be old fuel,or as said ,carbs shited up, the pump should stop pumping when the the carbs are full ,if its not , then it could be a split petrol pipe , put new pipe on & drain all the old petrol out of the tank& carbs , replace with new, might do the trick

well if i was talking from my back side,then so be it, ive done ok from it, i have 3 blokes working for me, 4 hols a year, 750i BMW, and BMW M5, not bad for talking shit

thats right ,that's why i think it could be inlet rubbers or compression, one more thing i just thought, on the inlets there are blanking rubbers, they are for carb vacuum gauges,they sometimes brake down & let air in, when a bike with CV carbs is at tick over,the butterflys are amost shut,there then is a very lagre vacuum in the inlet rubbers ,if there is a very small spit it will pull air though that spit,but haveing a good old think, its more than likely to be cloged air filter, that will make it run rich, & you did say she run ok with the fillter out and air box off,or you could say fu** it & fit some K&Ns !!!!!!! make life a lot easyer when you need to take carbs off,

most obvious , ok, but it wont be that,if a set of carbs you know are ok & still you are having probs, you need to get compression test done, i know you siad the inlet rubbers are ok, but how did you check ? its not always poss to do a visual check, run the bike with the tank off , ues a long petol pipe, tank must be conected or it'll run lean, then put plenty of oil on each inlet rubber,in turn , if you get smoke out of the exhaust then that inlet had a split, or if you are in the Norwich area bring it to my work shop , ive been trading for 16 years, i have all sorts of diagnostic equiptment,

yep water pump seal,deffo, like he siad,water jacket is no where near the box, as for rs50,well sorry to tell ya mate,you'll never catch that !!! dont get pump kit off ebay bud, they just dont last, gen yam will be a bit dearer but it will fit properly & last longer, i have loads of youngsters bring their bikes to me to fit a new seal kit saying they had a go at it with ebay crap thinking its them not fitting it correctly Parsley ps your bike looks rite nice

just thought of something else , has the bike ever been fitted with K&Ns or the like, it may have been up jetted, have a look at the plugs, are they black, thats a sign that she's running rich, if none of these, then try getting a compression test, um, have you tried adjusting the tick over , sometimes they do vibrate out,sometimes it the real obviouse things that get over looked,I once had a bike in my garage, bloke trailered it over to me & he said it wont start,its completely dead,it was nothing more sinister than the kill switch was off!!

Its the idle mixture , its too rich, it may just be a cloged air filter , if not then ,what you need to do is this, take the tank off ,to gain access to the carbs ,on the top of the carbs, where they join the intake rubbers, there are 4 screws , 1 on each carb, they are slightly lower than the suurface and made from brass, turn them all the way in,then unscrew them 1 and 1/2 turns out, if you still have probs turn in 1/2 a turn untill its ticks over ok, if you still have probs, then your idle jets are blocked, but thats very unlikely coz she runs when cold , its deffinately not coil or leads, coils either work or they dont, leads will play up when they are wet, plugs play up when they are under pressure ,pulling away, uphills ect, if you need any help just i.m me, Parsley

Ment to say, to see if your sprockets are geting worn, spin the wheel backwards, the chain should sound the same as spining forward, to see if chain is worn, you should not be able to lift the chain off the back sprocket, ie- pull the chain at abt the 3 a clock poss, toward the back of ya bike, it should'nt move ,the more it move,the more shaged it is, Parsley

Hi when you say a tight spot, do you mean ,at some pont the whole chain gets tight or you have a thight link? if its a tight link then as above, but if the whole chain get tight as if its be over adusted, it will be a hores shoe link, if you get the back wheel of the ground, turn it untill it gets tight, the link will be just getting on to the rear cog, if this is so, take the link out , & bin it, replaes with a rivet one, hores shoe's a crap,& must not be relaed on ,Parsley

Hi, i recon its the power commander soft wear, its very un-likely to be petrol, all moden bike are made to run on std unleaded, power commander cost a good few £££, id take it to a dyno & get it set up by the pro's, if your map was free, whos to know if it a good or bad map, or you could spend a bit more, & get the proper soft wear, then you can load what ever you like onto the cammander, ie race, bimble,town ect Parsley

Hell, whats a photo bucket? never mind bucket, think ill say f###et thanks for your help,think ill get one of my lads to sort it for me,they'll know what all then fields & IMG's are all about but ever need advice about bikes & bike motors ,im ya man

How'd ya get pic on here??? Im a bike mec,not a pc bloke,its took a good while,with help from my teen age boys, to work this out!!! but got some pics of my FZR & some of the wife's YX, i've done a fair to both bikes & would love show em to ya all ,Parsley

Ahhh Im always the last to know,

have a look at this made me smile i think i've pasted the link on here right

Yep ,a good car wax,then when the water build up ,look to one side & then the other, the wind blows the water of, works for me or you could try what my missus do, she wont ride her YX if there's the slightest risk of rain, she recon it'll make her bike dirty!!!!!

Thats gonna be ya batt, you can test tha alt by starting the motor,with the lights off,put a multimeter on the bat,try to hold the revs at 3k, meter should read 13.8 v to 14.2, if you dont have a m/meter,a indication that the alt is charging is to turn on the light then rev the motor to 4-5k light should get brighter

hi, DONT DONT DONT put car oil of any kind in a bike, Car motor oil has a detergent in it & it cleans the clutch plates & make them slip at high revs, just when you need a bit of power to over-take, clutch will let you down, trust me on this one ,im a bike mechanic, Fully synthetic is mainly for high reving motors R1s ect, semi is good for your bike , I use Motul in my workshop,the difference between synthetic & mineral is, synthetic stay the same hot or cold,ie it does'nt go thin when hot, so is much better for high reving motors that run hoter than low reving motors, Parsley

were are you? if you are in the norwich area & can get it to me, ill fix it for you Parsley

Oh mate, sounds like it sized up,two stroke will sizeup ,then when they are cool they will free of a bit,but what happens is the rings damage the cylinder, resulting in compression loss ,look like you need a top end rebuild,Parsley

hi yes the best way of getting them out is to pump em out with the brake master cylinder, take the pads out,if you havent already done so, then pump the brake lever, watch which piston that gives first, then clamp that one with mole grips or some thing like that, then pump untill the other piston gives, when it does, take the mole grips off and pump untill they both come out, Parsley

hi , no you have nothing to worry abt, the 600 motor has the ignition slightly advanced for top end performance,so thats why it feels sluggish under 3000 rpm,driving through town is always a pain with them,i've a good few customers who have to have their clutch adjusted & even reyplaced Parsley

hi, there is a pipe that runs from the rocker cover to the airbox, its the breather for the motor ,idear is ,any oil mist is burt with the petrol ,it some times there is more oil mist than the motor can take in so this usually settles in the bottom of the airbox,then it will run out through any gap it can find,so give the airbox a good clean and keep an eye on it,if it gets worse then there could be a another prob, but that is very unlikely Parsley

Hell man thats realy bad luck, that is criminal damage, i would ask the seller if he had a falling out with any one,it might just be that some one was trying to get back at him not knowing he was going to sell it, if some one is cought ,they will be made to pay, aslo speak to the old Bill

no worries i'll be glad to help
