Do u no what size pin to fit in headstock to lift thanks

Que utilizaste para limpiar la motocicleta?

Thank you so much for this video. It helped me so much, because i have same model 1979. I bought this with only 5k miles and it was equipped with a no name brand carburetor. That one works frome driving perspective very well but obivously too rich since s spark plug is always sooty. I also have the original MIKUNI VM 28 SS which looks realy good. Main Yet 130 I carefully cleaned it up an gave it a try. It works but last Quartier of gas there is no performance above ca. 40 miles/h. then stop. With no brand i could go up to ca. 60. So was it sucessful when you changed your Main Yet? Maybe that could be solution for my old Mikuni to step Main yet up. I'am wondering since my Mikuni is still equipped exactly with stock components. No modifications have been applied so far. I think it should normally work with that at best performance.

Very useful video thank you. Question: what is the function of the 'switch' cable attached to the clutch lever please? I couldn't see you mentioning it on the video Many thanks

Thanks for sharing, i am doing similar mod on vfr800

I got one for the track. Love it there. Oregon Raceway Park... Wonderful rolling hills añd fun. I upgraded the forks with springs and tuned it to my weight and style. raised the rear and dropped the front. Changed to GP shifting and not many bikes were faster lapping. De tuned the settings a bit and rode it to Idaho...Ride dirt and gravel roads, too. Best bike so far, other than my 1st bike, a 500 triumph tracker, waay back.

I also have a 2012 wr450f and wanted it street legal so took it to this old man that said he's been working on motorcycles his whole life. Big mistake I made. Wanted it street legal now I have a wire shortage that's frying the starter and relay or solenoid somewhere. Took it back to him and says he's too old can't work. Mechanic shops for motorcycles charge too much an hour just to troubleshoot problem. He used very cheap wire with any abrasion or cut on it it'll touch ground and cause a shortage which I think it did already. Friend of mine is recommending this other guy but will see what happens. Thanks for the video

These F4i’s seem to have been gaining in popularity recently. They were extremely popular bikes when they were new and then it seems around 2015 or so they had became just old bikes. Now it seems, people have realized these bikes are not only durable and fast, but they have insane performance for a 600. I owned a 2001 f4i back when it was almost new and I loved it, but I heard all the talk about the 600RR being better or move up to a 1000. So I’ve had liter bikes and RR’s, a new busa. Now I’m back to riding a 2004 F4i and it’s my favorite bike ever. I love the gixxer 750 and I’ll keep that bike just because, but the f4i is fast, comfortable, and smoother, more enjoyable to ride than any super sport or cruiser I’ve spent any amount of time on. My son got me this 04 that has very few miles so it only needed tires and fluids, was otherwise like new. I’ll never part with this bike.

Great video, I too have a 2012 WR450 and I just got it street legal last week. I just got the license plate mounted today. I did most of the same things that you did, but did wire up the lights a little differently. I connected the positive wire for the tusk harness to the relay in front of the battery that turns on the lights after the bike is started. I like it because I don't have to have another switch on my handlebars and it doesn't turn the lights on until the bike is started, so it doesn't drain the battery. I also bought a switch from sicass racing that combines the start and kill switch into one switch, so that I could get rid of one more switch.

I have a 2013 with the dual sport kit. These 2012-2015 WR450’s are great reliable bikes.

great video this will save me so much time when people ask in the fb groups how to fix their bike i have yet to swap my pump out i only have slight issues starting specifically with the e start without the plug being pulled out but other then that i have my c1 mixture at 15 compared to your 6 i have a full exhaust though smells a little gassy but not nearly as bad as my friends carbed wr

Appreciat you

Which hose is connected to the map sensor

I did the fan switch mod today. Fan kicks on at 185 instead of 215. I ran the ground to an engine bolt instead of the radiator mount. Works just fine.

My 2015 WR450F often stalls at idle. I installed a Yoshimura muffler and it became hard to start and failed to idle at all. These bikes are fussy and need lots of fine tuning.

Awesome video. Thank you for sharing. Went to buy a bike this week and the guy was honest about the hard start so I pushed away. After watching your video I am more confident I can resolve or at least significantly improve it. Thank you again

I like the video I bought my 03 f4i during Covid 2020 And it’s also my first bike Like you I ride dirt bikes at 13 and loved it. I bought my bike at 27k and currently it’s at 42k I’ve gone out on some long rides 450+ miles in a day as well as a nice 13 hour ride. And I’m 6’2 and it is very comfortable during those long rides.plus having a 4.5 gallon tank makes for less fuel stops averaging 170-190 miles per full tank. I was going to sell it but decided nah I’m just going to change the plastics and keep it lol I highly recommend anyone to buy an f4i for their first bike.

When reinstalling the rear wheel on an f4i, do you know if the smaller and larger spacers go left or right side? I mistakenly mixed them up when getting my tires swapped

You will never see it again going to be torn apart and stunted.

Thanks for this VID! Not many out there like this and it is super appreciated!

Why on earth did Honda decide to makes this so fiddly...?!

insane information, thank you

Curious to know how you personally adjusted the cct once installed. Id prefer not to put fuel rail on and off just to restart bike (with air filter off), and have seen some people talking about how tight it should feel before moving locknut into place. Thoughts?

Great! 🥰

Hi, I also have the Honda CBR600F4i Sport version (exact same as yours) - I didn't get a manual with mine and the 2 I have found online have stated 2 different spark plugs to be used - IMR9C-9H and IMR9A-9H. Would you help me with identifying which one is correct? Also, how long should the chain I buy be, and how many teeth on the front/rear sprockets. Im new to bikes and trying to figure out what I need to order. Thanks for help.

The GYTR power tuner is available through Partzilla. They're useless though if you don't already have the competition ECU.

What rear jack is that?

Hello brother, do you know that yesterday my motorcycle started to fail when hot as if it ran out of gas, it is a 2015 wr 450, when cold it starts excellent but after 5 minutes of riding in 4th or 5th gear it is as if you turned off the gas and it goes off, could the fault be the fuel pump?

Thanks I’ll take a look

Where did you Order those turn lights. Cant find em lmao

Hi, You did not say if the bike run better with the 150 Jet.?

Ppl acting like this is hard to do lol. The fuel rail is literally 3 8 mil bolts like he said. And it frees up alot of space. It will make life easier. Get some quick disconnect fuel fittings and u can take the whole tank of easier but even without its not bad.

You did a great job don’t be so hard on yourself

Really helpful video. Recently bought a 2006 model and just starting to find my way around it. Your video really helped. 👍

How did you get the throttle bodies off the mounts the kne bit i needed 🤣🤣🤣🤘🏻great video though dude

Hey man can you tell me how many turns there are from full hard to full soft? I can’t find it anywhere in the manual. I know the stock settings but I rebuilt my forks and want to know if mine are still are still correct.

That had to be so scary... you did well. Are you going to do a debrief video about the experience?

Hey, thanks for this video, it's very informative. But I'm curious, what do you mean by wrong plastics in the beginning? They are not factory?

Just removed the throttle body on my 954. Remove the screws like he does, then there is a rubber seal that you need to CAREFULLY pry open with a crowbar (that what i used).

Is there any footage of you putting it back together? specifically putting the air intake back on because I cannot put the air intake tubes back in and I am wondering if there is a trick to it or if I just need to brute force it. Someone help me plase

This is probably the hardest way I’ve ever seen somebody change this. You could literally just barely lift the tank and use a couple extensions from the rear swing arm. Easy 10 to 15 minutes

👍🏻👍🏻👏🏻👏🏻

Can you post a link for the part for the temp mod please?

Air filter was upside down, that is why it didn’t fit properly, it even says “this side up” on the side you had downward. Thank you for the video. 🤘🤘

Dude thank you so much! My ex coworker knocked my bike over in our work parking lot and ruined it. Without this video, I never would've gotten my 2002 Honda CBR apart to find the issue. I really can't thank you enough! Keep doing watcha doing because even if you don't know what you're doing it's still helping people like me sooooooo much!❤❤

Aloha🤙 my friend bought a honda CBR 4fi 2002 and he has such a problem that when the motorcycle is cold, the engine speed rises to 4k. but when the engine warms up, the speed becomes normal 1k-1.5k. Maybe you know what the problem is?

How is running now that hot temps are coming?

Is it possible without the fuel rail being taken off and how much should I tighten the manual cct bolt down just enough for it not to raffle and maybe a little more or no

Those throttle bodies are tough to remove, go back on much easily though thankfully!

what is nomal temp mine gets two 224 sitting at idle is that normal for just letting it sit and run ?????
