@@dakavanagh David, I put the carbs back in the bike, but I didn't have the success you did 😒. The bike will start with the choke but it won't idle. I'm feeling a little stuck. Not sure what my next step should be. The bike did idle before I replaced the mixture screws. So, I'm not sure if the screws are the problem or if it may be something else. Any advice you have would be greatly appreciated. PS, the previous screws were turned all the way in. With the new ones, I did the 2.5 turns back you recommended.
It was a surprise how clean your old fuel filter was! I will replace my fuel lines soon. Do you know what size clamps and lines are? Maybe 8mm? Thanks for sharing!
I remember tightening those screws, and I changed them to socket head cap screws so I could use a ball-end Allen wrench. Some of the angles can be tricky.
@dakavanagh Mine is 25 feet. Model is 747 O.D. designed and built at northern Spain, that I bought new in 2001. It's a one design racing boat for 5 or 6 with a maximum crew weight of around 800 pounds, designed by this naval engineer named Iñigo Echenique, who had designed the rudder and various parts of the Spanish America's Cup boat that raced in San Diego. My rudder is a downsized A.C. rudder huge for the size of the boat and looks like the fin of a big whale. In fact it's almost a carbon copy of those kind of fins. Most boats went to France and the class went to the smaller and easier to be trailed and raced Laser sb3, now renamed as SB20, which is a 20 footer for three. I'm from Bilbao, located in northern Spain near France, sailing the coasts of the Bay of Biscay since I was 3 months old.
I like idling below 1 thousand rpm. Adjustable idling screw of mine doesn't align well to pass the screwedriver through the hole below the plastic or rubber round grey cover. Maybe my carburators are not perfectly in place after they were removed to rebuild them? Do you have problems finding the idling screw with screwdriver through the hole?
I've been able to find the idle adjust screw pretty easily. I shine a flashlight into the hole in the frame, to be sure I know where to put the screwdriver. If it isn't close, yes, I suspect something isn't installed properly. The engine is hard-mounted, so it would have to be carbs, or how the idle screw bracket is installed.
@@Errol.C-nzIl There is a hole on the left side of the bike, covered by a gray plastic circle. A long screwedriver and a flashligt and bit of patience allowed me to adjust idling to 1000 rpm +/- 100 rpm as specifies the service manual.
I think you're right. It runs smoothly once I get it off idle, but at idle, it's not so smooth and getting it off idle takes a little coaxing. I ought to check compression, and ignition wiring. I do think cylinder 4 is a little "off" based on plug inspection.
Spray the header pipes with some water after minute or two of running and you will know which one is not firing. It sounds like it runs on only 2 cylinders when you hit the throttle.
hi David can you show where exactly the hoses from the carb tuner kit go in the carb ? you said there should be an allen bolt you took out and then inserted them...?
I knew I should have filmed it when I re-sync'd the carbs a couple weeks ago! Cylinder 1 and 4 are pretty easy to reach. 2 and 3, harder due to the water pipe.
Nice work 👌 question dude I have 1992 fzr 1000 just wondering what’s the battery voltage should be as I measured and it’s between 14 and 15v is it correct ?
I think that around 14.0 to 14.5 volts above 2000 rpm is alright. It depends on rpm and... meter accuracy, battery charge state, and a maybe a little on temperature also. 12.6 volts at around 20°C is what my meter reads the day after I had run the engine. Volts drop down to 12.3 if it's colder in the garage.
Thanks for the video, David! I recently bought this bike. I'm not an experienced mechanic, but I enjoy learning, and your video has helped a lot.
I'm glad to hear it! I'll try to do more.

Thanks buddy, very helpful, I'm getting my 1993 EXUP running after being stood up for a long while.

Do you know what size clamps and lines are?
Maybe 8mm?
Thanks for sharing!
HELLO !!! WE DONT SEE THE DETAILS BECAUSE OF CAMERA. !!! FROM GREECE !!!
Hi, I didn't notice in your video if you tightened the boots after setting the carbs. Did I miss it?
I remember tightening those screws, and I changed them to socket head cap screws so I could use a ball-end Allen wrench. Some of the angles can be tricky.
Some of my tools are onboard sailing sportboat too.
What boat have you got?
We "used to" have a Catalina 27. We've given that up to focus on other things for a while.

@@dakavanagh I have to try the flashlight.
Thank you!

Its not firing on all 4 cyl, you can clearly hear it. Did you manage to get it run on all 4?

@@Jumbojt I have a thermal camera that attaches to my phone. It shows them all heating up, but I think 4, not as much.
@@dakavanagh They will heat up but not as nearly as those which run properly.

These came on the bike.
