$1100 Big-Bore Yamaha YFZ450 First Ride (EVERYTHING WENT WRONG)

[@joeymac837]

24:28 T0 24:38 the front left wheel is locked solid while you are riding.

Hope you get that Yamaha figured out Joe. Keep up the great work. No matter the weather or circumstances you put in a lot of effort to save these old machines. Appreciate you 🤙🏻

[@mmaaddict78]

If you have to go over three turns with the fuel screw, you need to bump up the pilot jet. These oversquare high compression four strokes will get super hot if it’s sitting idling. They will actually boil the fuel in the tank if they don’t get enough air moving(riding very slowly) to keep everything cool.

[@benny33730]

Even Stevie Wonder can see that bikes running real lean

[@braydenburkett3452]

@@benny33730 he’s not wrong at all, no bike should sit there and just idle, if you have around a 98ish millimeter piston sitting there and the antifreeze isn’t getting any air to cool off. It’s gonna over heat

[@benny33730]

@@braydenburkett3452 I'm not sure of the point your tring to make but he's way up north in the snow and bike has an electric fan to kick on when coolant temperature get hot and a water pump circulating coolant but that has nothing to do with header glowing it's doing that because not enough fuel in mixture

[@braydenburkett3452]

@@benny33730 no I understand why you mean, and it takes quite a bit for the fan to turn on, I was chasing my tail on my 07 tuning it and any time I got it running good or in the general area, after a few minutes of idling my pipe would glow… not trying to show you up or anything. Sorry about that man

[@showmaster0377]

My yz 450 was the same way. You had to keep her moving or she gets hot. Ultimately the reason I got rid of it because I only ride woods most of the time

[@danebowen729]

Careful with the aftermarket fuel screw at 4.5 turns. They have been absolutely known to fall out when turned that far. Look it up. Best is to bump the pilot to a 55 (which is huge, I know), and then turn the fuel screw back in.

[@2vintage]

Yeah that's the plan. Definitely a huge pilot.

[@sandmanbub]

Hey Joe, does that front left wheel spin freely? Noticed it sliding through the snow, at one point, while the right one was spinning.

[@braydenburkett3452]

If it’s just sitting there and idling for more than 2 minutes and still gets red it’s not good but it’s normal, yfz’s run very very hot and don’t like to sit and idle… they like to scream

[@frederikmesser7463]

Some engines do not charge the battery at idle. Try revving it up and see what the voltage does. I doubt the stator is shot.

[@preez77]

Correct! Most engines actually won’t. I check it at 3k rpm

[@larrywarner9314]

Joe put a bigger pilot jet in your carb , you shouldn't have to turn fuel screw out that far

[@dallasstepto8409]

Before you go pulling it apart to check head gasket go and buy yourself a test kit that tests if combustion gases are in coolant. Your water pump spins so that will also cause the water to push out of the fill port when you're reving it. Same thing a car does when you have the cap off and rev it

[@douglasuhde799]

When you drop spark plugs down the hole like you did there is a chance of knocking out the gap clearance. You should have placed a length of 1/2 inch fuel line on the end of the spark plug and turned the plug in. the same for removal. This also works on the HEMI engines!

[@James79561]

Voltage regulator is bad . That is the best running bike on the channel so far !

[@carlnelson1400]

I have same wheeler with bige bore. I installed a cbr 600 battery and that is 180 cca. And also bolt on battery charger for better charging. There is a little cutting by the battery area to fit the bigger battery.

Not sure if you noticed joe but the front left wheel wasn’t spinning just after you got her started in the snow with the screwdriver in your hand 👍🏼

[@royhenson3379]

I noticed that also.. The front left wheel was locked up..

[@clintcando8028]

Yep. Judging by the baldness of that tire, I would guess the brake is hanging up on that side once the caliper gets hot.

[@riley_swan]

Try changing the voltage regulator for the charging issue

[@1982HondaATC70]

You don't have a working charging system, it is running on battery voltage until the battery can no longer power the electronics. It should be of no surprise the radiator fan doesn't have enough voltage to work and it begins to overheat. Stop riding it until you have a solid 14+ volts at the battery while running.

[@txgamer9428]

Great video. I have a 2006 yfz 450 that I need to start working on and your videos will get me motivated. Just an fyi, you need to install a kickstart b/c the batteries suck.

[@Alexwinter123]

You have to account for three things, Elevation-Temperature-jets, lets say you have proper jetting already. When its colder weather you have to add about a quarter to half turn on fuel screw rich, Listen to the rpms very closely after each slight turn on the screw, Find the happy middle point, where its not too extremely high/fast but a nice solid idle, Your pilot jet is for idle/low rpm, Your Main is for 70% to 100% throttle, if its spitting and popping depending on the color of flame it is either too rich or lean. Only turn and adjust fuel screw when the motor is at operating temp. Start up procedure,(cold start only)*,( Key on, Ignition on, Pull choke out, Blip throttle once to get fuel in carb, turn on bike, leave choke in for 5-10seconds, Turn off choke, after once warm adjust fuel screw. Keep a Battery junior 800 Battery Maintainer on your battery so it always starts up 1-2nd time, When in storage for long time and u have the gas turned off for carb during storage, turn it back on, then on cold start procedure blip the throttle 2 times and let it wake up to its normal idle

[@justinmyers6449]

Really hope it sorts itself out, seems like you really have a lot of fun on it

[@frederikmesser7463]

Are you sure the battery was charged 100%? it seems really weird that the stock battery barely cranks the engine over. maybe it is losing charge from a parasitic draw?

[@cheto2952]

No the battery is not working they need time charge like 16 his time get a full charge. Slowly trickle charge

Bro that pop at 31:04 though 😬.. u could even hear it on the video.. anyway thanx for the videos.. u one bad dude and your videos keep getting better.. did u ever find out what brand big bore is in that quad..? I got a buddy of mine that wants me to install one on his 06 yfz450... also I just finished building my very first yfz450 (had bad piston n cylinder /broken valves) any way at first it was leaking coolant (after first start up)and then after it stopped I think I overflowed it.. but now runs good (semi good lol only choke on 🤪 got adjust carb) anyway my headlights won't turn on i checked a bulb looks good and when I hit the switch to turn them on i hear a click sound coming from maybe area around cdi I think there's the rectifier or some electric box.. so I assume they are trying to switch on but nothing.. what would you check first.. btw mine is an 07..also I gotta mention that my light switch is broken from the part were you switch from engine run or stop...might that be it?

In my experience, those kind of batteries are junk. The best ones I’ve found so far are Yuasa brand sealed gel batteries. They last a long time and perform well even in the cold. They are a bit pricey though.

[@Daniel-Biruk]

Actually I found that a Duracell gel agm battery is the best battery life and instant power when you need it but the problem with these batteries is they need a recharge every 1-3 months

[@frederickgiordiano2105]

If you suspect a short, measure the current instead of the voltage when attempting to start it. If you measure the current from the battery and the current going to the starter, the difference in going somewhere. Without the head lights that should be no more than 2-3 amps.

[@motomechanic5711]

Your crank might be bad. It cranking over slowly could possibly be a crank with a tight spot.

[@jimmy1life]

Did it still glow after the new piston.

[@jadanparra582]

Thats because a dirtbike isn't very much meant to run lean and glow red hot. A yfz450 is notorious for glowing red hot. I build them and I own 7 yfz450 carb models. These bikes just aren't meant to sit at idle and be reved at idle.

When it first cranked over slow a stuck compression release was my first thought

[@bdrook2]

hey man, do what you do everyday just dont vlog it, but was watching this and noticed you checked coolant while bike was hot/warm, looked like that anyway, pressure will be created when its hot from being hot and water pump forcing coolant around, you open that up hot and thats the weakest leak its gonna come out there, id re check the system while the bikes cold, if it still sprays out of fill area when cold then its most likely pressure in system, if it doesnt i dont think itd be head gasket, plus it didnt look like it was dropping white clouds of smoke. Just thought id throw this in the mix so you dont have to rip head off if you dont “have” to. Goodluck!
