Man, Quadzilla has a special place in my heart. Growing up in the 80s and reading about it in magazines it was revered and basically put up into mythical status. I would beg my parents to take me to the local power sports store to see it in person but it was never in stock. Got me hooked on quads for sure.
I had a lt 250 R when I was 14. My buddy blew it up on me. I've wanted a lt500 for 25+ years. I finally pulled the trigger n got myself one. Best choice ever
Had the piston skirt break off in my Quadzilla also, did the same thing. Total rebuild, added the crank bearing sleeve's and been running for 15 years now.
I have also built one of these. You'll want to speak with Todd Witz. Since you are tearing down you'll want to do at least the following - main crank bearing journal inserts - cylinder ear reinforcing - o ring the head The cylinder head also needs a major reworking to make reliable, they just weren't right from the factory. - use 2 green o-rings for the powervalve (known leak point) - RM wrist pin bearing & kevin cunningham billet thrust washers. - mic the shift forks! Best of luck with your build man! I have almost 10K into mine, worth every penny when it's done! Pair it with Todd's porting, LED trx250r airbox delete, VM44 carb, Steiner billet intake, Q2.0 pipe, and that thing will be NASTY! I also have some sweet billet Mossbarger reeds for this if you are interested :)
Mike Steiner did a billet intake for my 87 LT 250R. took almost 2 months of wait time and 200$ but was worth it. And bought some billet thrust washers from Cunningham. he's actually gonna be at our local track..Newtown Drag way in Newtown VA next week. he always comes out.
Need more videos ASAP!!, I’m going through withdrawals not getting videos faster lol…really looking forward to this build. Don’t do a full on restoration like 250r but just restore/clean up really good what you have there besides plastics they Dunzo.
Mike, ur KFX 450 & new YZ125 are absolutely keepers! 💯 Both came out better than anticipated. U have best of both worlds. Tho a newer Raptor 700R would round things out real nice!
Deff gonna make a sick addition to quad wars!!! Sucks about the motor but I had a feeling it was more then the piston when he said he got it to move 1/4" but stayed stuck lol. Dude bro u gotta do an engine vid on that right?!!! Hell ya man, love all ur engine builds bro. U legit should be a pro, u need to be in a shop somewhere haha
I grew up riding 3 and 4 wheelers. Mainly Honda's on my uncle's farm in Georgia. He always had a quadzilla in his barn that I never saw him ride but I always pictured him flipping his hat around and flying up and down the road on it everytime after I left.
I have an 87 zilla as well, y’all may have opened Pandora’s quad. The zilla’s are notorious for being the biggest pieces of junk ever. Don’t get me wrong I think they are boss machines when running, but just so many stupid motor issues. Like the fact that the water pumps are all faulty from the factory and leak through the weep hole. They also pull head studs loose unless you get stud work done. And not to mention the fact that they literally rip the ears off the cylinders on these bikes. All this happens on stock bikes for no other reason than the fact they just were not manufactured right. And finding parts is also very fun. This is going to be a tough build and if y’all have any questions feel free to hit me up. Good luck👍
Aso I figured out my warrior new clutch issues, I removed the shutter springs and added a steal ring to the inside of the stack. I used to slip in every gear now it hangs the front tires first through forth👌
The Q-Zilla is worth fixing properly. These old big bore quads and dirt bikes are like Toyota's, regardless of age they always hold their value. I have too many toys and all of them need fixing. Sadly I don't have a lot of time and endless fat-stacks to work on everything at once. Luckily my three-wheeler is the cheapest thing to work on since it's a small displacement unit. I've got some parts on the way to fix up the valves/head. :)
The washers for the wrist pin is a mod for the lt250 and lt500. Don't remember what it helps. But love and hate the way the bottom end is. Wanted to see it rip. But glad to see a build
I sure miss mine. All I know about speed is that the road got so narrow I had to slow down! My local Suzuki tuner "Chris Grissom" said it WILL go 100 if you can ride it. So I sold it. Common sense sucks sometimes but I'm still alive and can feel my legs...
I'm only going by your description of this video. "Only this (Suzuki 500) could stop the fastest quad of all time". You are partially correct. Only a wheeler with that size engine, and being a 2 stroke, could compete with a Yamaha banshee. Not stop it though. Lol
I was excited for the "giveaway " and I didn't even enter! lol Congrats #45 BUY A HELMET!!!! And tear it up on ur new predator! since Mike built it prolly has about an extra 73hp so be careful!
Hi guy's just subbed to your channel i live over the pond up here in Scotland and iam looking for a Yamaha blaster fly wheel can you recommend somewhere i can purchase one. All the best guys 👍👍🏴
Damn man where did you get my quad?.... I want it back.... In 6 months... You can keep it until Janurary i reckon, just clean it and make it nice for me!
FMF makes a wicked pipe for these, makes a huge difference. These machines can eat clutches so i'd upgrade or at least rebuild it. These engines are in a low state of tune. Id at east mill the head and run it on race gas.
Badass quad but I'd still take a banshee. Reasons behind why I would take a banshee. It's twin cylinder/carb. They have numerous parts out there available, you can make them into fire breathing monsters given enough time and money. They are over all durable, don't suffer from transmission issues or other problems that plague other quads.
I'm about to recieve 2 1985 (I believe, I haven't looked too closely) honda 110 atc's I'm really taking 2 to make 1. Should I throw some videos up of me doing the rebuild? I'm only 20 and this is the first full rebuild I've done to a machine. So the quality won't be amazing, but it's a learning process. I'd like to note that the quality if the videos probably would be the greatest at all haha 😅
Trying to message him on Facebook!!!! He needs to steer away from trinity lol, stiner or Todd witz the only 2 guys and most definitely big volume pipe and carb
87 zillas with the 6 stud head and other issues being a first year model are much less desirable than 88 to 91s and to make an 87 reliable you should be prepared to spend alot of money. It's a luxury machine to have, if machined and modded enough to make it reliable, the main issue being the head gasket on the 87s, in stock form they are guaranteed to blow, run lean, grenade we all know the story. There are other frame and suspension issues I believe with the 87s as well. I hope if the machine is being rebuilt it will be done properly, so it will be a reliable, long lasting insanely powerful motor. They're supposed to handle pretty bad hence the aftermarket a arms, so as I said, a completely luxury to own and really meant mainly for being good in a straight line. Very similar to a Tecate 4, a macnine I have a ton of experience with having rebuilt one mechanically pretty much front to back, besides the motor. 42hp at the crank stock, these kinds of machines are like shopping carts with rockets strapped to them and owning them is not because you want the best riding experience lol. Just my opinion, I assume you do have an 87 and that is why it's in the state it's in fresh after a "full resto". I came very close to purchasing an 87 but once I learned about all the issues and how inferior they are to the 88 - 91, ill just keep waiting for an 88 to 91 thats not destroyed but needs some love. Either way vintage machines of this era are becoming so popular and expensive that its becoming a rich man's game, though deals do still pop up. If you guys do this one right I have a feeling it would generate a strong response from the audience base and maybe you could show in detail how to address or make superior the 87 issues. Id love to see it rebuilt, properly.
@@fastmachines500r8 If you say so. Duncan racing I believe are the premiere zilla builders. I've never owned a zilla, but I have a ton of machines of this era, this is what I've heard about the 87 zilla. The head is a shitty, inferior design, why running without a head stay on a motor that has inadequate head gasket sealing would have any change on whether it blows or not is beyond me, but I am not the ultimate authority. 88 to 91 cylinder is the quick, best way to make it somewhat reliable. Duncan racing has built some really nice, amazing 500's. They seem to be popular with the sand or desert riders where too much power is never enough.
@@Donny_Buysall the vibrations cause the head stay to pull the head up, that’s how it blows head gaskets, Duncan, full Tilt, DrQ, hpr, trinity are all great when it comes to zillas
Stock air box is junk don't over tighten. We trashed ours and made some aluminum pipe and k and n filter with outer ware with t clamps. Looks like you have a 87 with 6 headbolts 88 and up have 7 no but deal. Look on top of the piston and see what number you have, I think you can bore it about 10 time's. We had a lot of top ends until we went to straight race gas and motoul 800 at 50 to 1 , remember more oil more heat . One other thing is on top of the head blead the air out after you get it warmed up every time you run it you'll be shocked how much air you'll get it makes a hot spot if you don't
0:14 I could feel the pain in his voice when he said it wasn’t his own bike 😞
Lmao
You guys diagnosing this quad is like a hospital drama “its not looking good” “dont know if we can save it”

Always flattering me with the comments Den; here is a link to the engine build - th-cam.com/video/AdnBYPCWSDc/w-d-xo.html
So good to see you guy’s working on something together. It’s going to be a beast.
My friend had one of those bikes, it had gobs of torque. Porting really wakes them up even more, add a bigger carb and a good pipe and hold on.
That Zilla looks so good on your channel!! Excited to see it going again!
Hopefully another series of restoration vids like the Raptor or M309R. Those are my favorites
The raptor was the first videos Michael sabo did
I grew up riding 3 and 4 wheelers. Mainly Honda's on my uncle's farm in Georgia. He always had a quadzilla in his barn that I never saw him ride but I always pictured him flipping his hat around and flying up and down the road on it everytime after I left.
Lt500 is fun and torquey but feels like riding a jet ski and it isn’t the crazy out of this world end all beat all quad of people’s imagination.

even John said RAFFLE!!! LOLOLOL 😆 I can't help myself sry lol😝
Definitely do billet thrust washers and a 98 rm 250 wrist pin bearing.
X2 on that.
Glad to see you getting your hands dirty on your own machine. Take your time its not as bad as it seems it will be a beast when its all back toghter!!
Aso I figured out my warrior new clutch issues, I removed the shutter springs and added a steal ring to the inside of the stack. I used to slip in every gear now it hangs the front tires first through forth👌
Them old Honda 3 wheelers use the frame as an intake as well...as the commercials used to say for them "making them a virtual submarine"
Yep my 85 honda 250 sx was like that & he Honda 300 fourtrax fourwheelers are too
That's a legendary quad and needs a frame off build don't half-ass it do it from the ground up
I'm not taking anything away from Q but he is not the only choice out there and there are some that have far surpassed him
@@herbsampson3842 who is Q and what does your reply have to do with the comment above.
So glad to see a zilla. Check the frame over for cracks really good.
Man I can't wait for quad wars 🤣👍🏽
I’m looking forward to the next qaud wars with the Zilla awesome bike
Can confirm every project/used bike has a bent steering stem, my past 4 have had bent stems. It’s heartbreaking really!
Dude hell yeah you gotta do a full build video on the LTR450!!!!!
The Q-Zilla is worth fixing properly. These old big bore quads and dirt bikes are like Toyota's, regardless of age they always hold their value. I have too many toys and all of them need fixing.

Were doing a Zilla build right now, good timing on this series.
Heck yeah I love learning about two strokes. I can’t wait to see what the how the zilla works!
2 strokes are the best!
The banshee killer 😈
Fact
Mike you prima-donna lol gotta change wardrobe on video🤣🤣🤣 can’t wait to see you guys get this beast up and running
Hey man im getting one this Saturday 😂😂 i will keep up with these new vids, havent really seen any since you finished with the banshee
I can’t wait for these videos
I think a banshee motor is better for power than the Suzuki 500..the extra displacement just isn't enough to make up for the shees 2 cylinders.
Banshees have a lot more room and parts availability to make much more power then the quadzilla.
Awesome vid and edits and filming and bike
do you remember the roost boost ignitions from the 80s i ran one on my Suzuki 250R loved it !
Awesome cant wait to see this thing rip always liked these 👌👌👌👌
Great video. Killer quad.
Good luck John an Michael. Hope it's a monster!
Love the zilla you guys will do it right im sure
You should race it against John’s kx500!
You won't want any other after you ride it 😜
Looks like a fun build, too bad you don't go with a stroker crank on the quadzilla, port n polish, ect... soo much potential even on pump gas!
RIP lt500 at least she will be back it will be a beast in qaudwarz!
Use mothers aluminum polish to bring back the fenders used it on my banshee plastic with a heat gun to get the flex marks out looks perfect!
Cant wait to see how this comes out.
Badass!!!!! Should just buy it from John
The washers for the wrist pin is a mod for the lt250 and lt500. Don't remember what it helps. But love and hate the way the bottom end is. Wanted to see it rip. But glad to see a build
What’s goin on with the ap3racing website wanted to order colored hoses but they’ve been down for a while now
Do you put 32:1 for your 250r
I sure miss mine. All I know about speed is that the road got so narrow I had to slow down! My local Suzuki tuner "Chris Grissom" said it WILL go 100 if you can ride it. So I sold it. Common sense sucks sometimes but I'm still alive and can feel my legs...
I had the air cleaner bolt fall off and get sucked through the intake and tore up the case.
I'm only going by your description of this video. "Only this (Suzuki 500) could stop the fastest quad of all time". You are partially correct. Only a wheeler with that size engine, and being a 2 stroke, could compete with a Yamaha banshee. Not stop it though. Lol
Man I hope it's not to bad but it doesn't look good fer quad-zilla but u two will bring him back to life🤟🤟🤟
Pull the whole motor, you're splitting the cases. You need to check the bearing pockets as well, most are worn and need sleeved.
I was excited for the "giveaway " and I didn't even enter! lol Congrats #45 BUY A HELMET!!!! And tear it up on ur new predator! since Mike built it prolly has about an extra 73hp so be careful!
I know you won't see this but my dad has one and the airbox lids are huge restrictions
When you guys going to come out for glamis?
Cant wait to see it ripping
such a good channel
"its an easy one should just be a top end job" hahaha
Hi guy's just subbed to your channel i live over the pond up here in Scotland and iam looking for a Yamaha blaster fly wheel can you recommend somewhere i can purchase one. All the best guys 👍👍🏴
I had the same situation with my blaster. The exhaust skirt blew out
Damn man where did you get my quad?.... I want it back.... In 6 months... You can keep it until Janurary i reckon, just clean it and make it nice for me!
u cant just bend those fender brackets back?
You guys should go all out with the quadzilla
Duncan Racing knows these in an out !!!!!
That is exactly what had happened to the 85 Lt250r that I got. But then I did a big bore on it 😎

Please make a vid on how to rebuild it.
big tip would be invest in a gimble even if it is a cheep one. it is hard to watch a video that is this shaky.
