PROJECT: Yamaha R1 Fuel Pump and Pressure Regulator Check

[@cunkrr2335]

Can i replace my current fuel pump with an outside pressure regulator like the one in this video that connects to a hose, with one that has an internal pressure regulator?? Where a hose wouldn’t be needed anymore

[@BIGWILLSCARCARE]

Im not sure but if you do some research it might be possible

I need some advice regarding to my 2004 R1, i service the bike myself, bought it 6 months ago, before 1500km (now 45200km) changed oil and filter, spark plugs, coolant, repaired starter motor (new brushes), adjusted TB intake vacuum. Engine runs smooth and pulls strong without any hickups, starts cold and hot without problems. The problem is when i start the bike and take it to warm at working temperature and higher (fans kicks in) without riding it and then shut it down it starts without problems, when cooled down a little (70 deg C or so) it also starts at once without problems. BUT when i ride it for i while and then shut it down and let it cool down a little (70 deg C or so 5-10 min.) it WONT start at once, starter motor is cranking with normal speed but it takes 3-5 seconds to turn off the fuel light and start the engine. Another thing, when i ride it for a while, shut it down and start it instantly there is no problem. I dont know what to do, it is a minor but annoying problem and i cant solve it. Other than that thing bike running smooth, pulls strong, fuel consumption is normal, no abnormal mechanical noises from engine.

@branko917. Try running Cevron fuel treatment at least two to three tank full with the treatment. It's available at Autozone in a black bottle

I have a 2006 r1 and I just replaced my motor not I am having a problem with it getting to much fuel it floods out if I unplug my fuel pump I can start it but only idles. When I plug my fuel pump back in it floods my motor out any help would be greatly appreciate

[@BIGWILLSCARCARE]

@tony zsvasky did you change your spark plugs, air filter? Other possibility may by the computer

[@F30Gee]

O ring in the fuel pump sending unit.

[@BIGWILLSCARCARE]

What was the original problem why you changed the motor?

[@dchrislerj]

Oring on injectors

[@alejandrotirado8846]

Hello did you find the issue? What causing the problem?

[@BIGWILLSCARCARE]

@Alejandro tirado yes I did it was the spark plugs, even though they only had about 1k or so on them

[@mikhail805]

@@BIGWILLSCARCARE have the same issue right now. My spark plugs were burnt. And one of them was wet. I changed the plugs and still the same issue. It’s possible the coils are bad. Not sure

[@BIGWILLSCARCARE]

@@mikhail805 that's what I would check next. Spark plugs, coils, injectors and also change the gas if it's old and put a treatment in it Techron was recommended to me by a dealer. Thanks for watching please Like and Subscribe if you haven't already

What are some symptoms of a bad one? I was slowing down to a stop. Was at 13mph, I pulled the clutch in, and then the bike just died . Struggled to turn on after. One person said it’s the valves but I just did them 3k miles ago and spark plugs too. Then my friend said it’s this and he’s having the same issue with a Honda he has after I showed him this Link to video of it happening kzbin.info/www/bejne/Y3OzoHxvf9dmhck

[@BIGWILLSCARCARE]

@ExtraSync that is one sign of a bad fuel pump, also check the coils, and if you had the bike sitting for a while the spark plugs may not be good. I know you changed them but I had this problem before with only about 2k miles and it was the plugs. Thanks for watching please Like, Share and Subscribe if you haven't already
