Finally an informative video I can follow and learn from. Well done and Thank you 🤙👌

[@joystickdad3035]

Best video out there this is my first time doing any work on my r6 as I'm a new rider this helped alot thanks man

[@vp573]

Awesome video, soothing and easy to follow… Thank you!

[@madabouthistory4611]

after reading few comments my question is answered sorry my bad, great vid thanks

[@daarkke]

Great video! Thank you for sharing beautiful bike btw

[@welmercabugwas3977]

Really nice video 👍🏾 just ordered the kit and ready to work on my bike 2001 r6 soon. Going to clean my carbs through your older video. Keep up the good content dude

[@welmercabugwas3977]

Also do you know where I can get a wiring harness for the rear? Mines was all broken and fucked up

[@WillowsWorldofDIY]

I would look on eBay or call a Motorcycle salvage yard to see if they have a wiring harness.

[@bandit08]

Nice Wheelie!

[@madabouthistory4611]

hi again, when adjusting the screw am i looking to see the gauge settle or go to a certain number? im kinda confused. thanks

[@KevinBeGood]

Hey I just got a 2000 yamaha r1, can you help me out with the vacuum lines/forced induction lines and coolant lines running to the carburetors.? Like where do they come from and where do they go? Mine is missing all that and I'm trying to piece it back together. Also are the vacuum cannisters necessary? I'm also missing those

[@johnshanahan1673]

Very good video thank you

[@davidlmf]

whered you get the steerping damper? i can't find a bracket for this gen :(

[@johnhorstmann8585]

great job

[@seanhayden103]

So vacuum hose from carb 1 goes to carb 3, carb 2-4?? I have a 2000 YZF R6

[@martinpeat8374]

I've got a thundercat, is the process exactly the same? New to riding and (very) novice at any mechanics

[@TheJanis1993]

You're the best.

[@kickersixx9014]

You rock willow

[@iankee7433]

Can u tell me where the vacuum for all four is at? 2001 YZF r1

[@Fox_Pawtography]

So for the adjustment screws. Once u set the gauges do u tighten or loosen the screws? If u do tighten do u tighten hard? Nice vid btw!

[@WillowsWorldofDIY]

It depends on the vacuum pressure readings on the gauges. For example if the vacuum pressure on carburetor 1 is higher than carburetor 2 you will tighten the adjustment screw, but if carburetor 2 has a higher vacuum pressure then carburetor 1 you will loosen the adjustment screw. The adjustment screws all have springs on them to keep tension on the screws and prevent them from backing out from the engine vibrations. So when I tighten the screws I don't tighten hard like when torquing a bolt. I hope this is helpful. Thanks for watching!

[@shinobisensei4027]

Thanks you have very good and detailed videos! I just have a stupid question, what values have to be on the gauge?

[@WillowsWorldofDIY]

The values don't really matter. You want to make sure that all 4 gauges are reading the exact same vacuum pressure. I hope this is helpful. Thanks for watching!

[@shinobisensei4027]

@@WillowsWorldofDIY Thanks ! :)

[@kickersixx9014]

Hey willow kicker here again, could you tell me how the air fuel screw works on these carbs does screwing them in richen or lean out the carbs? It's a fuel screw not an air screw if I'm correct in my thinking so screwing out half a turn should richen it a bit? It's not a huge fan of my new k&n filter and d&d exaust pipe I'm guessing, it runs fine when it's warm and horrible when it's cold so I reckon it's running lean at the moment

[@WillowsWorldofDIY]

Hey Kicker! You are right, it's a fuel screw. It's recommended to start at 2 turns out. 3 turns out will richen it and 1turn will lean it out. Most exhaust systems will recommend installing a jet kit that has #152 main jets on carburetors 2 & 3 and shims on all the needles to richen it depending on your altitude or elevation. I don't usually do air/fuel adjustments without an exhaust analyzer hooked up because it shows each individual cylinder air/fuel ratio's and how well it burns the fuel. I hope this is helpful. Thanks for watching!

[@joystickdad3035]

About to do my 08 wish me luck grate video

[@bakangsebitloane5013]

how did it go

[@crystalclearlightingelectr3263]

​@@bakangsebitloane5013i bet it didnt go so well when he found out it wasnt carbureted and it was fuel injected lol

[@branko917]

Can i synch throttle bodies on 04 R1 with this type of gauges, are they precise enough, i think that vacuum values are 22 kPa (165 mmHg) at engine idling. I saw this type of gauges on ebay. Where did you buy yours. Problems that i have with my 04 R1 is that she wont start normal (longer cranking) when hot or cooled down a little, she starts ok when applying little throttle, she starts ok when cold. Engine work normal, no strange sounds (ticking, rattling, exhaust backfiring) fuel consumption within specs, pulls strong.

[@WillowsWorldofDIY]

Yes you can sync the throttle bodies on a 04 R1 with this type of gauge. It's not as accurate as a mercury gauge set, but it's accurate enough to balance the carburetors and about 1/4 of the price. I got my gauge set from Amazon, I posted a link for the gauge set I bought in the description of this video. I hope this is helpful. Thanks for watching!

[@silverfox9875]

Thanks man ! Ive had a probem with my R6. When i am in 2nd gear and go from 5000 rpm and higher, my bike is " lugging". Hope that a sync will help

[@WillowsWorldofDIY]

If syncing the carburetors doesn't help you might want to check out my other videos on removing kzbin.info/www/bejne/qnOpaWiOa8aAmKM & cleaning the carburetors kzbin.info/www/bejne/hJPGimeMjrClm9E. I hope this is helpful. Thanks for watching!

[@silverfox9875]

@@WillowsWorldofDIY thanks man! Have a nice day

[@Kyre5049]

Did you adjust the pilot screw (air/fuel ratio)?

[@WillowsWorldofDIY]

I did not adjust the air/fuel (pilot screws) in this video. I adjusted the carburetor synchronization screws. You have to drill the carburetors at certain points to gain access to the pilot screws if it hasn't been drilled out by you or a previous owner already. I recommend using an exhaust analyzer when adjusting the air/fuel ratio. I hope this is helpful. Thanks for watching!

[@antonvanheerden4999]

Hello where does the vent and overflow go to? Because I just got the bike and it doesn't have that 2 pipes on the fuel tank

[@WillowsWorldofDIY]

The vent and overflow tubes go down from the fuel tank and route down past the mount for the anti freeze overflow tank on the left side of the motorcycle and then continue down to a loop on the kickstand mount and just hang down a couple inches past the kickstand loop. They don't connect to anything and are supposed to be open so they can drain any excess fuel spillage underneath the bike. I hope this is helpful. Thanks for watching!

[@GurillaRon]

Wait what year is your bike?? I didnt know you could put your handle bars on top of the triple clamp!!!

[@WillowsWorldofDIY]

My red R6 is a 2000, I have an aftermarket Scotts upper triple tree clamp that drops on each side and allows you to mount the vortex handle bars on top of the triple clamp. I hope this is helpful. Thanks for watching!

[@valdemar7337]

I got a buddy who said he'd clean and sync my carbs for $150 dont know if its worth it do have him do it or for me to do it following these videos.. Any thoughts?

[@WillowsWorldofDIY]

Synchronizing the carburetors isn't difficult and you really don't have to take much off to get to the adjustment screws. Remove seat, hinge tank up and remove the air box. I would charge $100-$150 to sync the carburetors, but if you buy a cheap gauge set you should be able to do it yourself under $50. I hope this is helpful. Thanks for watching!

[@The_Rejected_Son]

What’s the goal vacuum your trying to reach for a r6?

[@WillowsWorldofDIY]

When syncing the carburetors you're not trying to reach a goal vacuum number. So it doesn't matter if its 5, 10 or 2 HG. You just want to make sure that all 4 carburetors are reading the same vacuum numbers. So for example if it's 2HG then make sure all 4 of them are 2HG. You won't know what HG until you start balancing them. Start with carburetor 1 and 2, get them reading the same HG numbers, then move to carburetor 3 and 4 get them reading the same HG numbers (the 1&2 carburetors will probably be a different HG number than the 3&4 carburetors), then you can balance the 2 and 3 carburetors and all 4 carburetors should read the same vacuum numbers. I hope this is helpful. Thanks for watching!

[@The_Rejected_Son]

@@WillowsWorldofDIY thank you

[@Joseph-jr9cf]

Is the bike running while doing this ? Also why aren’t the needles moving much ??

[@WillowsWorldofDIY]

Yes the motor has to be running and warmed up to sync the carburetors. Mechanical gauges aren't as accurate as a manometer style gauge set, so they don't move as much at low vacuum pressures, especially because you have to close the valves some to get the gauge needles to stop jumping all over the place. Also I'm only blipping the throttle so the motor isn't revving up much and there's not much vacuum pressure at idle. These Mechanical gauges worked good and i noticed a big difference at lower rpm and idle after I made the adjustments. Plus they are about 1/3 of the price of manometer gauges. I hope this is helpful. Thanks for watching!

[@Joseph-jr9cf]

@@WillowsWorldofDIY So I start the bike, runs fine for about 10-15 seconds. All of a sudden the idle goes up to 3k and won't come down. Do you know what could possibly be causing this?

[@Joseph-jr9cf]

@@WillowsWorldofDIY Also thanks for the first reply that was quick

[@WillowsWorldofDIY]

Hi Joseph, Unfortunately I'm not sure what could be causing it without seeing it in person. Is this a new problem or did it occur after a recent repair? Did you remove and clean the Carburetors? Is the throttle cable adjusted too tight? Is the choke on or sticking in the on position? Have you or anyone made adjustments the the Carburetor (Air fuel mixture Screws or carb sync screws)?

[@WillowsWorldofDIY]

Also will the idle adjustment knob bring down the idle at all?

[@brennenmakela2360]

So i got a bike with no fuel lines no breather lines and no vaccume lines and the vaccume lines don't lead to anywhere except hook the carbs together? And when I turn the key on near the back of the motor a pump makes noise would it be a fuel pump or vaccume pump I'm not sure I am looking for help to figure out where gas lines run to and from and vaccume lines because I can't find much about it

[@brennenmakela2360]

And will it run right without the air box because I don't have that either

[@WillowsWorldofDIY]

It sounds like you are missing a lot of stuff, I can try and help. There's a link to a Service manual in the description of this video, it will show you the bike layout. The vacuum lines hook the carburetors together and then hook up to a vacuum canister. The pump you hear running at the back of the motor is the fuel pump. There is diagrams in the Service manual that show how the fuel lines are routed to the fuel pump and from the fuel pump to the carburetors. I hope this helps you. Thanks for watching!

[@WillowsWorldofDIY]

The motor will run without a air box, so I would start with getting the fuel hooked up.

[@brennenmakela2360]

I got it to start now and idle fine but I try rev it up and it's slow and boggy and won't go full throttle

[@WillowsWorldofDIY]

Did you take the carburetors apart and clean the jets?

[@adventuremanintheclouds8968]

I cannot believe you willingly put a metal tool on your painted metal tank.
