Using a carb sync and a Gunson colortune can really get the bike running smoothly. The colortune will show mixtures in the cylinders and you can visually see the rich/lean burn in each one. For the FJ you always want a richer mixture as it keeps cylinder temp down. Keep the great videos coming.
@@reneverheij6938 depends on how you ride the Yamaha fjs. They are air cooled and running them lean to get more power means they run hotter. Out on the highway at speed this is fine. However if tuned lean and ridden slowly in traffic on a hot day they can over heat and cook rings and valve guides. So running them on a slightly rich mix keeps the temps in the safer range when doing slow riding on extreme hot days.
@@carsonharding9852Makes sense! I try to never get stuck in traffic jams with the FJ. I kind of want a temperature gauge so I know when to shut it off in time.
Haven't done this with my FJ yet but I only do this when the idle is rough, the higher the RPM the lower the differences will be relatively speaking. So if you get it near perfect at idle it will always be really good at higher rpm's.
You should do a video on adjusting the carbs on the R1 just the idle screw because i cant find mine lol. All the forums say left side under the tank there is a thumb screw but idk.
Only if it has a throttle for each cylinder (*edit or multiple throttle bodies) - you are balancing the cylinders by adjusting the throttle body opening or air valve screw on each cylinder, then you want to get the o2 right on each cylinder, a colour tune is cheap way to do it - unless you have a 5 way gas analyser :-)
@@Numbnutz-Uk Thank you for the explanation! The car motor has 4 cylinders + 2x dual Dell'orto carburettor 40, these carburettors, have a screw to adjust (but I'm not sure about if they have "the throttle to each cylinder"). I'm not aware of those color tune, and that's amazing! The kit cost around 80€. I was thinking of buying an air flow meter, will that do the job? Cost around 50€. The 5 gas machine is too expensive :S More than 1500€.
Hi@@Filthat Well maybe I should have said multiple throttle bodies not just one for all cylinders. I'd expect your twin dellorto 40's have a throttle body for each cylinder / trumpet and 1 carb supplies 2 cylinders (one side) and the same for the other two. Google 'how to balance twin dellorto carbs' and see if you can see the youtube 'easy guide on a alfa'. You would need to adjust all 4 throttles You could use a carbtune (if you can fit the vacuum pipes ok, or a pressure meter (as in the vid) if you can access the trumpets ok. I'd prefer the carbtune as you can leave the air filter on etc. But have a look at both vids and decide which may suit you set up. The colour tune is a basic spark plug with a glass body so you can see the colour of the flame .. and you adjust the mixture to get the right colour .. but you'd have to move the colour tune into each cylinder and make sure you adjust the right screw. Tbh it may be better to take it to someone who can tune and set these up if you havent do this before and get them to explain it to you .. unless you want to do it and learn 👍
@@Numbnutz-Uk Yes, I already searched and saw some videos (including that one), but, have different methods and machines. I was checking this CartunePro, if it works. My strategy will be: 0 - Set the Valvules 1 - Air flow meter 2 - Cartune Pro 3 - ColorTune 4 - If's not right, not to go to a shop with 5 gas meter 5 - go to a shop if cant made it :S This will be quicky over 300€

Thank you I didnt know about the colortune. I will research it
But will you need 4 colortunes?
Why do you want the cylinder temp low though? As long as it doesn't overheat it's fine, right?

I used mercury. Explains a lot
I found out that I had a vacuum leak on cilinder 1 with this device.
Is it possible use this device in a car?
