Quadzilla Banshee vs Yamaha Raptor 700 race coming soon!

[@theboogieman401]

700 has shorter gears .

[@savagehawk4750]

Can't wait 👍

[@noostNL]

Yes. Let's go!

[@titletownclowns1545]

You know I love Warriors so I'm really glad you found the price to be fixable rather than part out. When you do put the Warrior back together use the manual, I think you'll find the other guy did rebuild the engine but missed some parts or just jammed it back together. The pin at 27:50 is a roll pin (as spilt on one side and hollow) not a bearing I don't remember ever seeing or needing a roll pin inside the engine as they are not strong enough to retain anything inside. Pops If you want the YZ80 cylinder ported I can show you what power Yamaha left on the table.Free as usual, if interested let me know.

You better shim the case where that gear/washer seized together as that sets the clearance on that gear. Just my .02

hi i just wanted to say i love your videosand you helped me get into dirtbikes and fourwheelers and one day i wanna repair stuff like you

[@joeypooschke7914]

Good job so far, the only thing different I’d do is when I take Engines out of the frame I would pressure wash the frame really good while the engines out, and I would clean all the Engine parts cases etc. before putting it back to together. I have really bad OCD so I’m a clean freak when it comes to my quads..

[@shaynedonnelly374]

That’s the way to do it. It’s best to do that as a habit and I’m pretty OCD myself but I’ve never once seen him once pressure wash anything other than the plastics. Then again wd40 is his preferred lube for everything including for the motor when he rebuilds them at all. Never seen him use engine lube and most times he’s working off the garage floor and new parts on dirty cardboard boxes. Fun to watch though cause he’s baffled when his rebuilds blow up lol

[@joeypooschke7914]

[@weeeee3468]

@@Davido50 i was just asking why does it matter if its slower😅

[@Stephen033]

That will be a good race and also if I was you, I wouldn't waste my time on the warrior engine. The early 2000's 350 raptor engine is the exact same as the warrior engines, all you gotta do is take the stator off the warrior engine and put it on the raptor engine. That way you can have a nicer newer 350 engine on the 97 warrior. The warrior engines are alright, but all the ones I've had, they all had weak oil pumps and them no oil gets to the top end and it shears the cam gear. That's why I put a 2005 350 raptor engine on the 98 warrior I had and I had no issues at all

[@Davido50]

2015+ Raptor 700R motors are enhanced even more than pre '15 models. Higher compression + even stronger internals etc.

[@Stephen033]

Yea they are nice engines but I was talking about the raptor 350 not the 700r. The 350 raptor is the exact same as the old warrior engines except the stator, so that's why I took the stator off the warrior engine and put it on the raptor 350 engine. It ran so much better and smoother and faster than the 350 warrior engine.

[@4.5.0.Garage]

@@Stephen033 the HP difference is good too between the raptor 350 and the warrior 350. The Warrior is so weak for a 350 it's gross.

[@Stephen033]

@@4.5.0.Garage you are right about that one. When I had the warrior, and it had the warrior engine in it, I couldn't hardly stand it up cause the engine was weak and the quad was really heavy to. But even tho the quad was heavy, it didn't take much for that raptor 350 engine to stand it up. It done really well. I wish I still had it.

[@DonKelleyMusic]

seriously - fantastic video. Please hold things further from camera in your hands though cuz it is always out of focus and makes me feel sick :-) LoL, but you know so much, thanks for sharing

[@sandmanbub]

Hey Joe, I couldn't see the clutch basket well enough to be sure, but it appears to have been "repaired". The clutch bolt with the head that was ground down was going through what looked like two tubes that had been placed there to replace what had been broken off. The broken, threaded piece may be where some of the metal that you found came from. Also, that roll pin looks like someone tried using it in place of a missing pin. It's been apart before and some of the pins (3?) were lost. Did you notice the scrape marks on the counter balance weight? Looks like it had made contact with the crankshaft counter weights. Did the gears that had the chewed up insides have bearings that are now missing? Might have to grind or mill the case where the gear shaft was held and use shims to regain the proper clearance. Can't wait to see it running with you wheeling it down the road. Peace.

[@sandmanbub]

Just watched the end of the video and one of my questions has been answered (the missing bearings).

Hey i have a taotao db14 i checked the oil and it had a lot of small metal shavings the engine works great but it has the shavings, what do you recommend me to do?

[@4.5.0.Garage]

I think your assumptions of someone trying to race this is correct. That clutch basket looks like it's eaten alot of clutch dumps

[@jonnyonwheels]

Not sure if it’s the camera or I’m just seeing things but it looks like the nosecone screws on your big impact are loose Joe. I know I’ve even had them eventually work loose on my SnapOn impact.

[@theboogieman401]

Joe please get a breaker bar lol the impact works i get it but when u have a 8k quad and shit gets stripped . cmon u got that nice google check .

[@trose7620]

Very clean motor. Get er running. Probably is new.

[@moval79]

Hey I have the same quad that had the same bearings and axle go bad. It looks like the axle also spun nside the crankcase and wore out the area that holds the axle in place so now the axle spins along with the bearings. Will this be a problem?

[@larrywarner9314]

To the Yamaha shop you go Joe

[@troyrosenbaugh9935]

YFM 350 X very solid motors. I can get whatever ya may need and get it shipped to ya. It's a new motor so no worries, my running one is cherry.

[@Steve-jg1yc]

I just bought an 02 Warrior And it wasn't running I finally got it running But once it fires up and warms up every time you hit the throttle The RP m's stay high Or if you shut it off and start it it will idle normally for a moment and then the RP m's slowly climb up Any thoughts of what that could be I already checked for vacuum lakes and I can't find any

[@RDEnduro]

Did you just get a fresh battery for the impact or keep trying? I thought you were going to get stuck at the flywheel bolt, nice man!

[@2vintage]

I got the air impact out haha

[@agethauno6592]

[@user-fi3fx5my2s]

I remember a year ago I did top end for a guy on a 2000 warrior it was really beat up, he said he had tried to rebuild himself but lost interest, he put it back together without oiler ring, I pulled top end and bout snapped, thought it was a joke or something, called him up, he found the other rings on his work bench.

[@trose7620]

That counter weight is your clunk. When running it smoothes out. Turns high rpms.

[@Stephen033]

That moped cleaned up pretty nice and runs dang good. Heck, you could probably sell it for 1,200 to a grand.

[@MaNNeRz91]

The hollow pin with the slit down is called a collet.. but where it came from?.... I do not know this information.... And someone put the wrong length bolts in to pop the chunks off the casting at the back of the threads

[@gbenother8755]

When I first watched your calculations at the end of the video, I was thinking, "Wait! He's not valuing the time, blood, sweat, and tears he's put into this machine. Obviously he's already invested several hours, maybe even a full day to diagnose, and it's going to take another full day to install the new parts when they arrive. Shouldn't the estimations include two full working days labor? " Bit then I thought, no, he shouldn't include that in the calculation at all, because I figured he'd be doing this anyway, whether there was money in it or not. That, to me, is the very definition of "passion".

[@bananabrooks3836]

Wondering what caused those rollers to fail like that. If it was swarf from the clutch side going places with the oil wouldnt other bearings be demonstrating wear?

[@2vintage]

The guy put the rod that the rollers go on in wrong. One side of the rod has a stopper that fits into the case to prevent it from moving.
