I built my engine from scratch with NO experience!

[@namesake7169]

Godaamnn son!!..mad respect..i'm inspired to blow my engine out..nah..but i'm inspired to remove each and every component in the engine and reassemble it, looks like a lotta fun.. (i do have a legit mechanic on speed dial) i have an FZ1N 2012

[@TheDonInLondon]

Haha thanks buddy, was a lot of work but great fun and I learnt a hell of a lot! But I would say, if it is not broken, don't mess with it haha. I am happy I managed to get the chance to rebuild it, but it was full of hard times wanting it to be simple. Thanks again buddy!

[@megamember6195]

I also own a Yamaha FZ1 Fazer and i love it. Such a beautiful and comfortable bike and that brutal accleration over 6000rpm is just addicting. Cant belive how its possible to rebuild a engine with no experience but okay ;). Be sure to treat her nice afterwards and offer her the best full synthetic oil possible. :D

[@TheDonInLondon]

Thanks buddu, they are great bikes!! Cannot get rid of her hence why I gave the rebuild a go. Really happy to have done it. Was pretty straight forward to be honest but felt amazing to start her up the first time!

[@jeffreyyeater1780]

After 6000 you better be hanging on . I have one too. 2012

[@AndyManCam]

AMAZING work! That broken stud would have had me on ebay looking for complete engine!! Awesome effort and big balls for all of it mate. Definitely not for the faint hearted and you've saved yourself thousands!! Hats off.

[@TheDonInLondon]

Thanks buddy. Well I did consider a new engine but I wanted to do it all myself. I ended up spending more money than buying a second hand engine as I had to buy a lot of parts, screws and gaskets which all add up. Thanks for watching Andy :)

[@janvandebeek3576]

Great respect Guys, That`s called a daring difficult job!! Hope it runs as good, or better as before. Good Luck!!

[@christopherhuggins3212]

Great build and I know that feeling when you snapped the bolt also new sub from America wish we had a better variety of bikes like y'all do in the UK

[@TheDonInLondon]

Thabks buddy! Yes was a horrible feeling at the time but the feeling of removing thr bolt felt amazing! Glad to have you with us... we do have quite a few bikes here :)

[@maumauhun]

What an incredible job you doughnut! Hats off to you, I could not have done it myself, I`m really happy for you and also that your channel is doing really well!. Lets go on a ride soon dude! PS... no speeding! :-D. Much love

Hahaha cheers buddy! Soon she will be on a ride out don't worry :) speeding, never!! Always got to stay legal right haha

[@tonyb5884]

Very well done on the build!....i used the same stud extractor on a Bandit 1200 when i snapped one stud changing the exhaust...worked a treat! I also have a Fz1 and looking at the exhausts studs i think i'm gonna snap every one when i take the header off to clean around there cos the rust and the heat looks like its welded the studs in there.....a lot worse than the Bandit looked

[@TheDonInLondon]

Thanks buddy!! Yes was a pain to remove but had to get them out and happy I did to get new screws in :) thanks for the comment

Nice one man, I remember changing the clutch cable on mine having to take the tank and airbox off I thought that was a big task lol BTW I'm guessing the stud extractor worked well? I have one of those ones too just in case.

[@TheDonInLondon]

Haha yes still a big job! They work pretty well but worth heating up the stud before. I will explain more in the next video:)

[@MyRandomLife247]

Well done mate and good effort with the rebuild. What happened at the end during first startup?

[@TheDonInLondon]

Cheers buddy, was just a quick start up as pipes were not on properly etc... will post another video once the custom build is finished on her :)

[@DeWoodysShop]

Since you changed the crank did it have the same journal size numbers as the original? One thing about the rings, its not always necessary to change them, but i would check all of the end gaps before putting them back in. Especially when going in a different cylinder set. It should be fine though unless your rings were really bad. Looks like you may have a bit of an exhaust leak?

[@TheDonInLondon]

Yes same numbers as it came as a set. The orings came also as a set with pistons and barrels to be sure. Exhaust was not on tight but yes it was an exhaust leak as i didn't want to tighten all the way. Since fitting properly she works like a dream :) few changes still to make however

[@patricknumans]

Nice job! Must have been one hell of a frustrating moment when the bolt broke off. How much did those parts cost you?

[@TheDonInLondon]

Yes it was very annoying but glad I took the extra time to remove and replace it. A lesson learnt with aluminium bolts haha

[@HalfdeadRider]

Awesome job mate, especially for a first time rebuild, only one bold snapped and that one was really unlucky. Looking forward to see a startup, if you filmed it. What matts are those mate, they could come in handy for me pretty soon.

[@HalfdeadRider]

A tiny bit hasty on the start up comment lol ;)

[@TheDonInLondon]

Thanks buddy, yes was unlucky to snap but happy to have fixed it in the end. Start up not perfect at the first point, however it needed a new chain and tensioner which has been resolved. More coming soon! Matts from halfords very cheap and handy! :)

[@PsychoPaul13]

Dude I’d have definitely changed the Rings. Old Rings in a different bore what was you thinking 🤔

[@TheDonInLondon]

I bought second hand pistons and the barrels together and of course the same rings so it was all together. Meant i didn't need to rebore etc..

[@PsychoPaul13]

The Don In London that makes more sense.

[@TheDonInLondon]

Haha don't worry I thought everything through :) most of the things were replaced because of the amount of damaged caused

[@desert666josh]

great job mate, but did i see you run it without oil at the end of the vid? hehe

[@TheDonInLondon]

Thanks buddy! No but the first time you till and run it all the oil gets spread so you need to top up after which was done.. don't worry after all this work I wouldn't run it with no oil hahaha

Are you going to have to re torque the head after a few miles mate? Well done for your first rebuild! Time to move it on now?....🤔👍🏻😎

Should be ok without having to re torque as per the manual. Will keep her tbh after all this work. Am currently changing her look so will be making her a custom bike:)

Does the alternator shares the same shaft with the starter motor?

[@TheDonInLondon]

Yes it does, had an issue with the bearing which I will explain in the next video which I am working on currently

[@chong-kenglimdr8922]

@@TheDonInLondon It's a ingenious design to lessen the width of the engine at crankshaft level. Does the starter motor spins all the time along with the alternator, or is there a mechanism which separates the two after the engine starts?

[@TheDonInLondon]

@@chong-kenglimdr8922 i suppose so, not that experienced with engines as this was my first tear down and build. It does look like it disengages after the starter motor turns but I am not 100% sure to be honest. I did look at how it worked but was hard to do without spinning with the case open and didn't want to do that myself haha

[@jettran4465]

what was your riding style like? any signs or symptoms before the bike engine went? do you accelerated hard before the bike is warmed up (5-10 minutes)

[@TheDonInLondon]

Hey buddy, no always let the bike run to temperature before riding hard, even a few minutes before setting off. She did get ridden hard most of the time as I ride quickly. I did have the chain slapping sounds coming before which was quiet to begin with. I should have stopped then and got her recovered. I didn't have much experience on engines before and was told it should be ok to get home, until the big bang 🤦‍♂️

[@dabliatpizdets]

tell me it was running lean from a pipe or something man, the fact that it blew at 44k miles really worries me, im at 37k, about to do my first valve adjustment and i ride it like i stole it. just got my forks done and shit too.

[@TheDonInLondon]

No she was not running lean but my oil and water pump failed on me, would recommend changing your timing chain and tensioner though. I still need to finish a couple of things on her before I make my final video so will explain it there too.

[@dabliatpizdets]

@@TheDonInLondon I was gonna do a graves aftermarket tensioner and Im gonna do a proper coolant flush with engine ice, replace thermo... now I wanna open my water pump and see how good that is, damn thats nuts.

@@TheDonInLondon going off the fact that we are mandatory in replacing the drive chain, ill dreadfully have to take your advice on the timing chain as well. Its a lot of wrenching compared to a car, this is why more ppl dont ride here in US lol.

When u have the pistons out u need to put new rings on them otherwise they will never set right atleast thats what ive heard
