  1. hi i got an 1974 kawasaki f11 i rebuilt the motor ground up except i didn't replace thr coils and points. i put the bike together and it ran really well. but one day i went to start it it would not start. so i cheaked for spark and fuel it gets both and some times it starts for a second but quits and won't start again. i removed the baffle incase it was blocked no change. i have 3 spark plugs so it not them. after it tries to start it floods out. i need some help on what to look at now.
  2. i have an 1990 suzuki rm 125 the crank is bad will a 2000 or 2001 crankshaft fit the 1990 with no problem because i can't get a crank for the 1990

    1986 Honda XR250R Blows Black smoke

    i still can't belive that little 250 ate 2 1/2 gals of gas in 3 miles and it blew black smoke every second of the way i ended up walking it back after it backfire like a shotgun twice and died out

    1986 Honda XR250R Blows Black smoke

    thanks the bike got no leaks at all in the fuel system once i lowered the float to just a little trickle in the carb it started with the choke ran with out it but at idle it blew black smoke pull the throttle it revved and didnt come back down and no black smoke i turned the ide screw down didnt change it then it just stalled started it again blew black smoke then the same thing so i shut it off. so i took it apart and reset the float and cheaked the needle vavle by blowing down the gas line which is new with clamps on each end the and if i had an gas leak i would know it wounld be on the engine there no hoses leading the over flow away from the engine. i didnt have the manuel for this bike but i have an xl 500 manuel and the carb tear down looks to be the same. now i have the pilot screw 1 3/4 turns out according to that book. i have a new air filter but even with it in it runs better with out. what else to say? hmm start bike very very little black smoke can see best wen reviv from a stop first gear lots of power hit second gear good till half way then black smoke and bogs and seems to misfire. pull clutch and revev twice then back to accel perfect but still little black smoke til near end of gear then the same for the rest(at end of gear fine after the reviv in the middle. the reviv in the middle is to clear. the spar plug is black exhaust at end of the silencer like soot. i am stumped i was thinking maybe a bad float maybe how would i cheak it a like plastic rubber one and had the carb off no loose jets none clogged and pilot screw open(not blocked)the very first time i took the car apart to cheak the inside the little plastic cone like peice was up side down i fliped it back over what would that do if anything?and the needle on the throttle is in stalk position. and again there no mods to the bike what so ever just a blowen donut gasket in between the header pipe and muffler. but would that make it run leaner i have got no idea what else to cheak

  6. Hi i am new here i got an 1986 Xr 250 it got two new valves new piston rings and gaskets new spark plug and new fuel. she starts up one two kicks but puffs black smoke she running rich right? i took the air filter out and it helped cheaked the carb float level it all good. it burns gas like crazy with the air filter and no power in about 3 miles it emptied the tank 2 1/2 gal. with out air filter got power not as much as it should tho and a lot better on gas. the carb is like new in side and i cleaned it just to make sure nothing was blocked but still i don't need the coke to start and the choke is not sticking i even tried turning the pilot screw leaner it didnt help at all. the jets in the carb are 125 and 40 i think they are stock jets. could the jets be wore. i need some help i don't want to run without the air filter i need some help please?!!
