BIKERDAD Posted March 23, 2019 Posted March 23, 2019 Hi all . Ok you might remember few months ago I had problems with my Honda cb750 P reg 1996 . It just after its Ben parked up over the winter I did a service on it which I changed the plugs .to do that I lifted up the gas tank and when I put it back.down I linked up the air breather so the bike was cutting out after a few mins.So I sorted out the kinks and NOW when I was out just now every now then the bike was sluggish as if it was say running on 3 pistons not 4 ( I'm just saying the pistons as its got numbers in it to show 1 not running 3 is ) So I was told few years ago if you start the bike turn off the gas at the petcock then it suck the carb down as its starved of gas .. So I did that and it run out petrol turn on gas started off it went firing on all 4 .. Then about hour later it did it again I was doing about 60mph then opened the throtel and it just went sluggish again so did the petcock thing again . Cuts out turn on gas off like a shot. This time on way home . So from the sound of this I need my carbs cleaned ??????? If so how much do you think it cost .. As I need a new front tyre and the Mrs said one or the other ?? Quote
Guest Posted March 23, 2019 Posted March 23, 2019 Check that the tank breather isn't blocked..... When it starts to get sluggish, try opening the filler cap - if you hear a hiss or a sighing noise, the breather is most likely blocked. It should run OK after that, until the tank develops a vacuum again, when the cycle starts all over again.... Quote
BIKERDAD Posted March 23, 2019 Author Posted March 23, 2019 Ok I'll try that tomorrow . .Ill take the 2 pipes that are on the right side used the tank off and make sure they not blocked then I'll go out for a ride . I'm almost on an empty tank about 50miles.left then I'll take the petcock off make sure that's not blocked The parts guy at Honda parts thinks that as I have a fuel filiter under tank (My bike should not have one ) he says the last owner might have taken the one off the petcock as its £40 to replace its a gauz white tube like thing to a fuel filter outside under the tank which cost £5 Quote

This is easy , possibly dangerous but brave ....... Ignore the Mrs Quote
