fantastic video and production! I don't even own one of these, just love tear downs and root causing problems, which is what you did!

[@PartzillaParts]

Glad you like it Pearl! Thanks for tuning in.

[@dannysolomon3467]

Can you replace timing chain with out taking bottom case off

[@886165]

Good Video, the plug had no gap because the rod bearing failed and caused the piston to travel up too high

[@akawireguy1197]

Very professional. Well done.

[@gregdixie7637]

VERY informative!!!

[@denseleit]

Very well done video

[@cwirtz1854]

I got a kick out of John being passive aggressive

[@readmore3634]

Engine blocks are actually very intuitive.....Carburetors are a different animal...but if you study them very close...you can find the problem...

[@jorgecallegher9352]

Fantastic vídeo

[@chriscastillo9695]

thanks john, do you have video on changing a razor 900 jug'

[@AdrenalineJunkieProd]

Excellent video!

[@PartzillaParts]

Thanks AdrenalineJunkie! Glad we could help you get your RZR back up and running.

[@dennisbermudez7058]

Wassup man invite me to go ride out there I see most of your videos

[@dennisbermudez7058]

Yes good video

[@dennisbermudez7058]

Good video

[@jimmystiltner5267]

Why doesn't anyone show taking the timing chain out? Of a 1000 XP.

[@jimmyseamster6570]

Hi partzilla ! I have a 2003 kawasaki bayou 250 any videos on engine work or electric problems ?

[@rogerl8488]

dam you good!!!!!

[@PartzillaParts]

Thanks Roger!

[@chriscastillo9695]

do you have to pull motor to change jug on razor 900

[@SGTKILLJOY]

Can you replace the jug and pistons while motor is still in the machine. I see the top end kits with pistons. I am getting blow bye and have low compression in one cylinder.

[@zombieman382]

Anyone know how to get the timing chain off the crank gear on the bottom behind the flywheel? Do you need a puller, or do you have to split the case?

[@davepanko272]

How much different would this rebuild be on a 2013 Ranger 900xp?

[@josephjquintero8325]

can anyone tell me how to fix a airlock promblem for a polaris sport 400 coolent system?

[@Oldmanriverman]

Is it possible to remove the timing chain without splitting cases? Also what is the purpose of the U shaped retainer other than keeping the chain in place if dropped from the top?

[@michi_danksta]

Not possible. The lower block traps the chain. It is only accessible by splitting the lower case from upper case.

[@juanvilla5545]

Hi there could you tell me where can i find. Any piece of de engine. I need to repair one. But i dont found the piece??

[@PartzillaParts]

We have parts diagrams on Partzilla.com. Select the year and exact model, then click on the component area you need. All the parts are listed.

[@MrJerrid98]

instead of replacing the head wouldn't it be easier to put a thicker head gasket? Then it would put down the compression and give more room for the piston don't hit the spark plug? This coming from auto tech, those engines might not be possible to do.

[@PartzillaParts]

It's definitely not recommended. You'll just end up replacing it later.

[@Gen3Benz]

7:06 You called out main bearings even after seeing the smashed ground electrode on the spark plug...caused by the extra stroke by wasted rod bearings. Come on man this is first day stuff....lol Just joking btw, great video.

[@rodrigocampos9731]

Where is the number engine?

[@cumminsdakota1375]

are you continuing with the engine rebuild videos?

[@PartzillaParts]

Yes we are. Finished the engine reassembly yesterday so it will be released soon.

[@grantdubridge7995]

Isn't that a manufacturer defect?

[@PartzillaParts]

It was most likely a rebuild with the wrong size bearings.

[@ToyotatechDK]

The coloration of the oil on the lobes had me cringe 😮

[@realcyborgh]

terminator eye

[@PartzillaParts]

... is always watching.

[@chriscastillo9695]

[@PartzillaParts]
